Do you have leaky basement walls? The issue of our times is a changing climate, and the impact that has on all of our lives. As the air becomes warmer, and temperatures rise up, that means a more intense water cycle, with more moisture evaporating into the atmosphere.
That leads to changes in rainfall patterns, and more storms. Downpours are more intense. There is more snow, which melts more rapidly.
With an increase in precipitation comes an increased risk of flooding. If you own or rent a house, with a basement, you know what we are talking about.
The home’s foundation drainage system is interconnected and complicated, just like french drain, it includes the city’s sanitary sewer lateral, perhaps a storm service lateral (in newer homes), a weeping tile system that channels water away from the foundation, drain pipes. Any failure there leaves the home exposed to flooding.
Cost of waterproofing can total thousands
For most people, purchasing a home will be the most significant investment they make in their lives.
How many of us though have directly experienced, or heard horror stories, about walking down the basement stairs to find a foot or two of water, or a cascade of water pouring into a finished basement through a clogged-up window well during a heavy rain storm, personal possessions being washed away forever in some cases.
Cost estimates to fix water damage vary – but it’s in the thousands, all to repair or replace drywall, floors and hardwood, or anything electrical. Those home repair costs go up the more the water damage is left untreated, or if the homeowner is dealing with clean water as opposed to a sewer backup, or contaminated water. Around $1.7 billion is paid out in insurance claims due to water damage in Canada each year.
Moisture will spare no part of the home – timber, block structures, floors, and bricks. Many people spend a lot of money finishing a basement, perhaps creating a rental apartment for income purposes, all to help push up the value of that investment, only to have to do the work again.
For homeowners the issue becomes balancing the potential repair costs associated with a flood with buying flood insurance from your provider. That becomes even more of an issue for people living next to waterways – in case a river or body of water overflows.
Then there are the health effects – water damage leads to mould and mildew growth. You look at it and it seems harmless, but mould spores can travel anywhere, and can lead to throat and eye irritation, coughing, headaches, fatigue, fever, skin problems, nasal congestion, nose bleeds and allergies. It is important to not only get rid of it when you see it, but stop it from showing up in the first place.
Hydrostatic pressure and water leaks
So why does water leak into your basement?
Maybe you have heard the term “hydrostatic pressure”. By definition, it’s the pressure exerted on a fluid at equilibrium (not flowing) by the force of gravity. Hydrostatic pressure increases the deeper you get from the surface due to the increasing weight of the fluid from above.
Hydrostatic pressure is the reason you see water leaks in the basement walls of a home. Water that is building up against the foundation wall will eventually leak through eroding concrete, at the joint where the poured concrete floor meets the wall, and through cracks in the wall, mortar joints or floor if left un-checked.
With more precipitation, that becomes more of a factor, especially as the soil becomes more saturated. The more loose the soil, the more water it absorbs. That expanding soil also puts more pressure on the foundation walls. In the event of heavy rain or a rapid snowmelt, water tables will rise, putting pressure on a basement.
Window wells are one of the main causes of water leaks in to the basement. If your Toronto home has this issue you should contact a waterproofing professional.
Basement waterproofing will take care of this issue as we will install an array of systems to protect your home from flooding, call Canada Waterproofers today!
Cracks along window wells
Window wells are a weak spot in the foundation, and are susceptible to cracking which can cause them to leak.
A crack will leak if your basement isn’t waterproofed properly, Canada Waterproofers knows exactly how to repair those basement cracks the correct way, Call today for your free basement waterproofing estimate!
Cinder block wall cracks
Older foundations are generally built with cinder blocks and this is fine until they age. As the wall ages then the mortar between the blocks tends to loosen or crack which allows water to enter the basement.
Sump pumps have many benefits when installed correctly, but they can also cause problems if they are not installed correctly, or they fail due to either age or just bad quality, there are many good Sump pump systems that will last the test of time, and also there are many backup and warning systems that can be installed.
Drains and sewers backup causing water to enter basement
A drain that is backing up is a big issue and should be addressed immediately, you could have a root issue or even a broken sewer pipe that could be letting raw sewage enter your basement.
If you are seeing water rise from any drain in the basement then is it time to call in the professionals. Canada Waterproofers are filly licensed and insured and we will get your clogged sewer running in no time!
Concrete slab cracks causing leak in basement floor
A crack in a concrete slab could mean a few things, but the most common is hydrostatic pressure, which is a build up of water pressure under your slab trying to escape and eventually will push up and crack the slab, but also a crack may be less sinister, and it could just be shrinkage. Watch out for a white powder around the cracks which is the tell tale for hydro-static pressure.
This type of leak may be caused by a few things, one is that the weeping tile has failed, and another is that there is a crack in your cinder block foundation and water is entering into the hollow blocks and showing up at the base of the footer.
A professional will be able to find the cause of your leak.
You can’t control the weather, but you can control how well you protect your home. If you want to stop water from leaking into your basement there are a number things you can do on your own before contacting waterproofing contractors.
Landscaping should be a focus. You need to keep the water away from the house. Slope the ground away from the foundation, around six to 10 feet. Install asphalt or patio stones next the home, so water doesn’t settle into the soil.
Make sure the eavestroughs and gutters around the home are clean. Water will overflow if they are clogged by dirt or leaves and will over-saturate the ground next to the foundation or basement walls.
Make sure downspouts are directed to where you want the water to go, like a garden.
A window well with a clogged drain can lead to water flooding in through the basement walls. Placing covers over each of the window wells will help keep out leaves and other debris that can lead to clogs.
Clear snow away from the home’s foundation during winter regularly.
Protect your HVAC system – make sure the furnace and water heater is not sitting on the basement floor.
But if you really want to stop the problem of flooding at its source, you need exterior waterproofing or interior home waterproofing system.
For the average homeowner, not in the waterproofing business, a French drain, also called a weeping tile, is a trench filled with gravel or sand that contains a perforated pipe with filter fabric.
The purpose of a French drain is to redirect ground water or surface water away from building foundations. In the case of a home, the French drain is usually installed around the foundation on the external side.
We have said it before – with more instances of heavy rainfall, more water is being absorbed into the ground, next to the home’s foundation, meaning there is more water pressure on the concrete walls.
Concrete is a porous material, so over time, especially as the house shifts, cracks will form in the walls, leading to water leakages into the basement. Older foundations built with cinder blocks held together by mortar are particularly susceptible to erosion.
The size of the French drain or weeping tile depends on the anticipated volume of rainwater or runoff. Consult a professional from Canada Waterproofers about this.
Dig a trench alongside the footing of your house. The French drain will intercept water before it can enter the basement.
The French drain pipe is something you can pick up from a Home Depot or Canadian Tire. Rigid PVC with pre-drilled holes is a type of pipe that’s preferable in part because you can clean it with a plumber’s snake if need be.
The trench should be at least two feet wide. If the objective is a dry basement, make sure the pipe is positioned below the slab or finished floor level.
Lay the pipe down on the virgin soil. Make sure the holes in the pipe are pointed downwards. All the groundwater is sitting along the bottom, so it can then percolate into the pipe.
Wrap filter fabric around the pipe so dirt or weeds don’t obstruct the system. Pour one-half feet of gravel on top and over the side of the pipe.
The filter fabric is also laid over the gravel to prevent soil from getting through and clogging the perforated pipe that you just laid down. It is important that the French drain or weeping tiles don’t become clogged. If that happens then water pressure will build up and leak into your basement, through the base of the wall or through cracks in the floor.
Back-fill the foundation with topsoil, bringing it back up to its original grade level. Compact the soil every two feet.
Landscaping is a big focus at this point in the job. Always slope the ground away from the home’s foundation, around six to 10 feet. Install patio stones or asphalt next to the home, so water doesn’t settle into the soil.
A French drain is much easier to install during new home construction. It gets more challenging with older homes, especially if you have taller basement walls and you need to dig deeper to the footing level. Landscaping, cement walkways or backyard decks might need to be ripped up to install the French drain.
Installation is labour-intensive if you take it on yourself. It’s not something you want to install incorrectly, because going back in again to install it properly will be costly. Call a professional to take care of the job.
We’ve used Canada Waterproofers twice and had excellent service both times. A few years ago, they waterproofed our basement wall along the driveway, and they repaired the concrete driveway after the ground had settled. Recently, when we found water on the floor, we called Carl to help with a leak that appeared to be in our main stack. Carl sent Peter who expertly diagnosed and fixed the problem with minimal damage to the drywall. He replaced the kitchen drain pipe connected to the stack and replaced a faulty shut off valve under the sink. All of our interactions with Canada Waterproofers have been friendly and helpful. We have recommended them to family and friends.
I had a fantastic experience with Canada Waterproofers! Salesman Andrew was exceptionally knowledgeable, friendly and guided me through the entire waterproofing process as well as all possible options to solve my problem. He answered all my questions over multiple phone conversations and visits and never made me feel as though I was a bother. The hardworking crew, Dmitri, Victor, and Grigorii, displayed remarkable attention to detail and completed the job flawlessly all while keeping a tight, clean work area so my family could continue our daily routine without interruption of any kind. Haven’t seen guys hustle like that in a long time. I don’t often hire contractors to do work and when I do I take my time to find the right contractor. I can be picky and tough to please as my attention to detail can be excessive These guys hit the mark! Don’t look any further when hiring someone to perform any task listed on their website. My basement is now dry and secure. I highly recommend Canada Waterproofers for their expertise and dedication.
Slava Koval was the best!!! We had 2 different companies who came and quoted us tripled what we paid him. He was very honest and thorough. The other 2 companies couldn't provide us a straight answer and provided us insane quotes. I googled and found this company and gave it a shot. He came by right away to do a camera inspection and was blown away by his expertise. He told us what was wrong right away and helped us with other things. He even offered us complimentary camera inspection after 6 mos. If you google his name you'll see all happy clients. You wont be disappointed. Very honest guy and doesnt rob people! Thanks Slava and Canada Waterproofers!
I called this company to come investigate my basement leak and fix immediately. Upon investigation, it was made know it's was a plumbing issue. I dealt with Andrew and I couldn't question how intelligent he was which speaks from his years of experience. He did not have to rip the wall open. He walked around the house and checked all the wall outside etc .Oh well, it was indeed a plumbing issue and we paid nothing to get the leak source investigated.Thanks so much Andrew for your intellegent.I will recommend this company because it's clear they have experience employees that are ready to help and not take advantage.
Fast response and excellent knowledgeable assistance from Karl to diagnose the source of a damp carpet in our basement. Thanks so much and we will remember your company if we need help again in the future.
Carl and his team did an excellent job waterproofing a large section of my foundation, when finished everything was neat and clean. Carl and his team took pictures and videos during the repair which was very informative and helpful. Throughout the process he has been very responsive and accommodating, always happy to answer any questions that we have. His prices are reasonable and I would highly recommend him and Canada Waterproofers to anyone in need of waterproofing.
Valentine of Canada Waterproofers provided excellent service and good value for a faucet replacement and a further faucet repair. He was very polite and considerate and "went the extra mile" to provide good, reasonably priced service. Highly recommended!
Carl and the crew at Canada waterproofers are the best option in southern Ontario. Carl is honest and professional while delivering a high quality of work on schedule. They are patient and will answer your questions with easy to understand direction. It’s a no-brainer for any of your plumbing needs
This is the second time we’ve had Boris come to help us with our plumbing issues. Both times he was very courteous, knowledgeable and efficient. We highly recommend Boris to others looking for a solid plumber. He is our #1 go to!
Valentine from Canada Waterproofers came to my house and did a FANTASTIC job repairing a water leak we had. He diagnosed where the leak was coming from and then voluntarily chose to repair it with a high quality copper pipe which typically would've costed more. He also noticed another issue with the pipes where the previous contractor had implemented a poor shortcut solution that would've broken down over time and fixed that proactively as well. Valentine and Canada Waterpoofers went completely above and beyond my expectations and did even more than what was required of the job. They did all this at great value for the dollar as well. Highly recommend this company and technician. Thank you for your service!!!
We had a problem with our shower drain leaking and a botched repair job by a previous plumber. We needed to call in the real professionals this time and Val was our guy. Rest easy if he's the one to answer your call.From his calm and calculated demeanor to his willingness to listen and provide the right solution, it was an absolute pleasure to deal with someone at the top of his field. Highest recommendation!
Wow these guys are amazing. I had the pleasure of dealing with Carl. I had quotes from other companies which were comparable or cheaper, however after speaking with Carl I knew without a doubt I would be choosing Canada Waterproofers. His no pressure approach, guidance and sincerity won me over.
Boris is a true professional 5 star rating plumber because he determined the source of the 2nd floor shower leak right away which 3 others plumbers from other companies failed. He fixed the problem without opening the main floor ceiling. He showed up on time, ensured quality service and charged us a reasonable price for fixing the shower, replacing garburator and replacing kitchen faucet. All 3 issues completed in less than 2 hrs. We are so glad we found Canada Waterproofers online. We will strongly recommend Boris from Canada Waterproofers to our families and friends for their plumbing problems.
We recently used Canada Waterproofers for 3 seperate, complicated basement water, drainage, and flooding issues. Carl and his team consistently provided outstanding customer service with quick responses, willingness to answer questions and explain issues clearly, giving us high degrees of confidence in their work. They made these stressful situations more manageable than we expected or imagined. We highly recommend their services. One of the best experiences we ever had with a house-related specialist.
I am always skeptical of companies in these types of industries receiving so many 5-star reviews but with this one, I get it. Similar to others, we had a fantastic experience with Canada Waterproofers. They did interior waterproofing (with sump pump installation), camera inspection and service pipe replacement (from outside the house), as well as a main water valve change for us. Andrew/Andrii (the client rep) was a joy to deal with; responsive, friendly, detail-oriented, and gave the most competitive quotes (balancing experience and price) out of the many places I reached out to. Andrew the technician and the rest of his team were also great; they were on time, worked efficiently but carefully, and were communicative and professional throughout. We had a complicated service pipe issue that required detailed inspection and some analysis on how best to tackle it and Carl (the owner, I believe) came to do the inspection himself, who was extremely knowledgeable and clearly very experienced. We received detailed quotes before accepting the jobs as well as professional looking packages with warranty certificates, etc. following completion. The way this company presented itself - which it then backed up with its work - made us feel confident and comfortable throughout the process and brought my anxiety way down (which is not an easy thing to do, as I'm sure Andrii, who patiently answered my many, many calls and questions, can attest to). I have yet to find any reason not to go back to them for all plumbing/waterproofing related work in the future.
The company is not after your money. Carl, the owner came to our house, inspected everything and explained all the steps. He is honest and has a sense of humour. Afterall, he did not recommend waterproofing our basement. Can't get any more honest than that!
Andrew and his team did an amazing waterproofing job for our basement. Andrew came to our house to do the estimate and I received the quote the next day with all the details. Throughout the process, Andrew was very responsive and the job was done on time. His crew were very professional and organized. I definitely recommend Canada Waterproofers for anyone who needs that kind of project to be done.
I've worked with Slava and his team multiple times. Once for basement waterproofing, the second time to fix a sewage pump disaster that another tradesman caused, a 3rd time to upgrade the water supply, and a 4th time to fix an emergency plumbing issue. All on different properties and occasions, and all of which have been excellent work done! Slava and his team are experts at what they do, pricing is fair, and always professional. There's a reason why I keep going back. Don't look anywhere else, this is the team you want to work with when it comes to waterproofing and plumbing!
Slava is amazing he has been doing this for years... I myself have used his service in two different properties, very wise good price and amazing service! Totally recommend if you have a water leak related problem at your house
You don’t need to call around for a waterproofing company. We’ve done it, and we won’t go anywhere else. Carl is professional, knowledgeable, personable, and timely. Most importantly, he provides HONEST advice during assessment. He’s helped us with our house in Mississauga and our rental property in Hamilton when we found water in both basements. Thanks again
Andrew from Canada Waterproofers just completed the installation of a new sump pump at my basement. He is knowledgeable and accommodating. The owner is very responsive as well. I used to doubt the authenticity of all 5 star google reviews under a single company. But Canada Waterproofers does deserve positive feedback. Thank you, guys!
We worked with Carl to quote out waterproofing our foundation. On top of the great customer experience during that quote process the on-site team doing the work was hard working, efficient, polite and eager.Carl went out of his way in terms of follow ups to ensure we were happy with the service.Highly recommend this service to anyone having issues with their waterproofing and foundation patching.
Andrew and his team (all the Andrews!) were fantastic. From the initial on-site inspection for basement foundation leak and sump pump installation quote, to all subsequent communication, booking a date that worked for our household, and day of repair, the team was professional, friendly, courteous, informative, honest, on time, super tidy, and provided excellent follow-up. I honestly can't think of a better experience for customer service and quality tradesmanship start-to-finish. Looking forward to quoting future underpinning work with this awesome crew.
I was having water leaking in our basement for a while just after periods of rains. ,but every time it rain the leak was getting worse , therefore making me more anxious. So after looking online for a reputable company I came across Canada Waterproofers. I gave them a call and got surprised on how quick they were able to come and take a look and give me the best solution to our situation. Not only was the technician very personable ,but the workers doing the job as well. When they finished actually the area they worked on looked better than before. Definitely will be recommending them.
We had an excellent experience with Canada Waterproofers - they completed basement waterproofing, a sump pump installation and a back water valve installation. Their prices were comparable to other companies and we appreciated that they provided all the services we required. Andrew was courteous and very helpful answering all our questions throughout the process; a pleasure to work with. The crew was quick and efficient, the worksite was left tidy at the end of every day, and the work was completed on time. We've had quite a bit of rain since the work was completed and everything has remained dry. Would certainly recommend Canada Waterproofers!
Carl and his team were excellent and we have no hesitation recommending. Having undertaken an entire home renovation Canada Waterproofers provided great recommendations and pricing. We had a very tight timeframe to get the work done to stay on schedule. They started on time and finished in half the estimated time allowing us to maintain schedule. Work included a complete replacement of all our underground sewer lines, moving of rough in’s, new window wells and an entire interior waterproofing of all walls.
This is our second time using Canada Waterproofers and would never call anyone else. Their first basement waterproofing job for us has held for the last 6 years with no problems despite occasional heavy rains. They gave us really beautiful window-well covers too- our friends and neighbours ask where to get them . Aside from great work, they are on time, on budget and very polite. Plus they take good care not to damage your property! Also, great communication and follow-up! Carl and his team are top notch!
Contacted CW because a leak in the building's foundation was coming through our drywall and flooding the inside of our office. It took CW less than a day to completely patch the leak. There have been no issues since.
Canadian weather is extreme, to say the least. And unpredictable. Your home will likely be the biggest financial investment you will make. The definition of “home” also goes far beyond any financial connotation. It’s where you rest and re-energize. It’s where you raise your family. For many of us it’s where we work. “Home” needs protection against those weather elements.
Canada Waterproofers award winning waterproofing contractors has your back. After all, when it comes to your home, it’s all about peace of mind, isn’t it?
Basement waterproofing your home is like putting on a warm, dry coat, protecting you against those elements. Canada Waterproofers is the “Canada Goose” of home waterproofing professionalism, particularly when it comes to the basement waterproofing methods we utilize. Ideally, we recommend exterior waterproofing service in Toronto. However sometimes there is no other option than to waterproof from the inside.
Either way, your home will be protected. We guarantee your satisfaction with our lifetime warranty on our 6-stage exterior waterproofing option. Don’t settle for cheap, low quality material. Call us today to receive only the best!
Foundations that leak cause all kinds of damage to your basement walls – whether you live in an older home, or one that’s newer. If your basement is leaking then there is no time like the present to have it repaired. And if it’s not leaking, there still is no better time than now to add that extra layer of protection.
When a basement is excavated for exterior waterproofing, the soils that will be back-filled around the new foundation will be much looser soil than the surrounding, undisturbed ground. The problem with this is that loose earth will collect water much faster than undisturbed virgin soils. After the foundation walls are poured and the ground is backfilled then that soil that surrounds the new foundation will collect water and hold that moisture up against the new foundation walls. This water accumulates and eventually will enter into the foundation walls as they age and deteriorate.
How can I stop my Toronto basement from leaking?
The only way to relieve this pressure is to install protective layers on the walls, through a system of weeping tiles and electric pumps, so that this accumulation of water can be redirected away from the foundation and allow the surrounding soils to eventually dry and settle.
A leaking foundation may seem daunting to fix, but we can assure you that with the right waterproofing methods your basement will stay dry, in large part via a series of foundation protective coatings, and sealers, which will keep the water from penetrating your foundation walls. Weeping tiles will carry water away from your foundation and protect your basement from flooding in the event of extreme weather. A membrane will protect the wall from damage and keep your waterproofing system intact for a lifetime.
Why is it important to stop leaks & waterproof your basement?
Moisture can cause all kinds of damage to concrete, timber, bricks, and block structures, which in the end can cost you thousands of dollars in structural repairs.
Maintaining a dry basement is more important than you think, as mould spores can travel throughout your home and cause all kinds of health issues. Although a little leak may seem harmless, without the protection that proper waterproofing provides that leak could be detrimental to the health of you and your family.
Waterproofing your basement from the inside is a great option for certain houses, although we always prefer to protect your basement from the outside. Unfortunately sometimes there is no other option but to waterproof from the inside.
Things you should know
Many companies like to tell you that waterproofing from inside is the best option. They’ll tell you it best protects your foundation walls from water damage. But the truth is a little different.
Although you may not have any other option but to waterproof from the inside, at Canada Waterproofers, we always advise you to go into your waterproofing project with your eyes open.
Waterproofing from the inside will stop water from entering into your finished basement, allowing you to enjoy a dry living space. However there will always be a little bit of water trapped behind the membrane of the foundation, which will over a very long period of time deteriorate your walls.
What not to do after waterproofing your basement walls from inside
You run the risk of condensation building up after interior waterproofing is installed if the wrong insulation and vapour barrier is used, which could mean mold behind your walls. We like to call this the mold sandwich.
What is a mould sandwich?
A mould sandwich is when you have two waterproof membranes – a waterproofing membrane and vapour barrier, that doesn’t let moisture escape, allowing your rock wool insulation to become saturated, which will turn to mould.
So there you have it – a mould sandwich.
How do I stop this situation?
There are ways to avoid this situation and it’s very simple (We are not trying to scare you out of waterproofing from inside!).
After waterproofing is complete, all you have to do is have it spray foamed during the refinishing of your basement. Yes, it’s as simple as spray foam.
Spray foam becomes its own vapour barrier, eliminating that mold sandwich, so instead of having two waterproof membranes you get a continuous membrane, as the foam sticks to the waterproofing membrane and seals and insulates.
This method of waterproofing was introduced into Toronto many years ago and now interior waterproofing is effectively keeping Toronto homes dry and free from leaking.
Protect your investment
Waterproofing has become popular in the last decade, as people are finishing basements more often in Toronto and the surrounding areas. Many Toronto homes have a very close proximity to each other and the only way to protect these homes is to install interior waterproofing prior to finishing the job.
The average cost to finish a basement is around $50,000, and this is why it is very important to have your basement waterproofed prior to spending this kind of money.
If a basement is finished with drywall and a leak occurs, not only does all the drywall have to be re-done but also the flooring, and baseboards, so that all the mold can be removed. With the damage, you would normally be looking at an additional $20,000 to $30,000 in cost.
A new waterproofing system can then be installed prior to refinishing your basement – saving you any unnecessary extra cost.
How much will it cost to waterproof my basement from inside?
Waterproofing from inside is much more cost effective than exterior basement waterproofing. That’s why many people opt for the internal option.
Interior waterproofing in Toronto ranges from $65 to $125 per foot. The determining factors are concrete thickness, height of basement, amount of footage, commercial or residential, accessibility etc.
The best way to find out how much a project like this would cost you is to give us a call. We will give you a free onsite assessment.
Will insurance cover my flood?
Insurance companies are great for many things, but if you mention to the insurance adjuster seepage or leaking after your basement gets flooded due to any type of leaking, which includes window wells, cracked, leaking foundation, sump pump failure, then we are afraid you are on your own.
Give your insurance company a call to add extra coverage so that you can be more protected.
Delta-ms drainage membrane is the final layer of protection that is applied when waterproofing your basement from the outside, This product is amazingly high quality that all other products try to simulate.
