Why do Basements Leak?

Basement leaks can be cause by many factors. Old pipes, poorly sealed windows and doors and when a basement is excavated, the soils that are back filled around the new foundation will be looser than the surrounding undisturbed ground. The problem that arises is that loose earth will collect water a lot faster than undisturbed soils. Those soils collect and retain water and moisture up against new foundation walls and the water that accumulates will eventually enter into the foundations walls as they age and deteriorate over time.

How to Stop my Scarborough Basement from Leaking?

In order to ensure moisture does not build up against the new foundation is to install protective layers on the walls.  A weeping tile and sump pump system should also be considered as a whole optimal solution. That way any accumulation of water can be redirected away from the homes foundation and allow for the new surrounding soils to dry and settle.

The Importance of Stopping Leaks

Most people may not think twice about moisture build up in their home. But as a matter of fact, moisture can do a lot of damage to concrete floors, timber, bricks, and block structures that make up a home and can cost you thousands of dollars in structural repairs.

If leaks are not properly dealt with, mould can appear and over time be detrimental to your health. Waterproofing is a great option to ensure your health and home are protected.


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.

Inside waterproofing will stop water from entering into your finished basement allowing you to enjoy a dry living space, but there will always be a little bit of water trapped behind the membrane, which will over a very long time deteriorate your walls.

For Optimal Results

Be sure to to use the proper insulation and vapor barrier after a interior waterproofing is installed or else you run the risk of condensation building up, which could lead to mould behind your walls and in your homes foundations. This is often refereed to as a mould sandwich.

How to Prevent a Mould Sandwich

There’s a simple solution to prevent mould sandwiches in your home. We ue a spray foam during the refinishing of your basement. It becomes its own vapor barrier which helps to eliminate the moisture. Instead of having two waterproof membrane you get one continuous membrane since the foam sticks to the waterproofing membrane and insulates and seals.

Protecting your Investment

Interior waterproofing has risen in popularity in the last decade. More people in the Scarborough area are finishing their basements as a solution to neededing more space at an affordable and convenient cost. Homes are located not too far from one another, in order to ensure these homes that are very close in proximity, interior waterproofing would be wise to install prior to finishing.

On average, the cost to finish a basement is around $50,000. When you spend that amount of money you want to ensure that its protected and it will last for many years to come. If a finished basement starts to leak, not only will the drywall need replacement but the flooring, baseboards and all furniture need to be removed to prevent mould.

Cost of Waterproofing my Scarborough Basement from Inside

When compared to exterior waterproofing, interior waterproofing is a lot more cost effective. Many of our customers opt for interior waterproofing. It can range from $65 to $125 per square foot, some of the determining factors include height of basement, amount of footage, concrete thickness, residential or commercial, accessibility etc. To ensure we can quote you accurately, get in contact with us today and receive a FREE onsite assessment.

Does Insurance Cover Flood Damage?

Insurance can be tricky, which is why we recommend speaking to a licensed insurance adviser to get more details. Some may offer coverage for an additional cost and others may have it already included in your home owners insurance. Be sure to keep your maintenance receipts to ensure that if a flood occurs you have the proper documentation illustrating you had the necessary system in place to prevent such an occurrence. This may assist you in getting your claim approved. Please contact your insurance specialist for more detail.
