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, 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.
The only way to relieve this pressure is to install protective layers on the walls, through a system of weeping tiles and sump 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.
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.
INTERIOR WATERPROOFING SERVICE
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 interior waterproofing 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 interior waterproofing is installed
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 interior waterproofing!).
After interior 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.
Interior 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
Interior 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?
Interior waterproofing is much more cost effective than exterior basement waterproofing. That’s why many people opt for the internal option.
Interior waterproofing 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.
