Interior waterproofing focuses on protecting the inside of your property using waterproof materials that add extra layers of protection to your walls. This approach is complemented by effective interior drainage to redirect water away from your home, requiring less excavation than exterior solutions.
We also repair cracks and gaps in basement walls using sealant and cement. If water pools in specific areas, our pump and drainage installations can efficiently channel it out of your basement.

A damp, moldy basement can harm air quality and cause respiratory issues, rendering the space unusable. Our interior waterproofing solutions effectively tackle these problems, restoring your basement.
While exterior waterproofing offers the most protection, it may not be feasible due to access or budget constraints. Interior waterproofing allows us to work from within your home, requiring less excavation while still providing lasting protection against leaks.

There are many solutions that we can use to make sure your basement is dry and cosy once again! We tailor the solution to your needs, and may use any one or a combination of the following interior waterproofing methods:
This is the main type of interior solution available, and provides a layer of waterproof protection that stops damp and mold from reaching the interior of your building. Delta membrane allows the water to flow away from the walls instead of getting trapped. This is combined with a sump pump and weeping tile drainage, which channels the water away from your home, and averts the crisis. The process is described more fully further below.
Foundation Gap & Crack Repairs:
If hydrostatic pressure or damp has already caused damage, then we can repair any gaps and cracks in your foundation walls or ceilings. These cracks are often points of entry for water. In order to repair the damage, we use hydraulic cement for larger cracks, and high quality water tight sealant where it is possible for smaller gaps.
If water builds up in a certain area, a simple drainage system might be the solution. Drainage systems channel water away from your property. They can be combined with sump pumps and basins; the drain takes the water to the pump, which gets rid of the water. This is known as water control. We often use drainage systems in combination with preventative measures such as basement waterproofing.
A sump pump is a brilliant system that removes excess water from your basement, and pumps it outside and away from your home. We can install sump pumps as a quick measure to rid your home of water, or in combination with full interior waterproofing services.
If you require more than just a small repair to a gap in your foundations, and need a lasting interior waterproofing solution that will provide your basement with full protection against damp, then our interior wet basement full systems can do the job. We still personalize the job according to your home, but this is an overview of the main procedure:
The floor around the perimeter that needs the waterproofing will be broken, and the concrete cleared away. This allows us to excavate on the interior of your home. This trench is not too deep, but allows us to accommodate the weeping tiles.
Holes are then drilled in the walls. This serves a very specific purpose. It allows the water that is trapped to be drained away safely.
Any gaps or cracks in the walls of your basement are repaired. In some cases this only requires a water tight sealant. If cracks are larger, we use hydraulic cement in order to restore the walls, and ensure no more water can get through.
A delta drainage membrane is applied to the walls. This stops any water, damp, or mold from reaching the interior of your building, and helps the water to flow off into the weeping tile drainage and pump systems.
Weeping tiles are installed. These are a high quality piping that will soon divert the water away from your home.
The weeping tiles lead to a sump basin, and a sump pump is installed. When the system becomes active, the water will be guided to the pump, and then will be taken outside of your home and deposited in a safe place elsewhere.
The weeping tile is covered with gravel to provide maximum drainage.
Concrete is then poured into the trench to a flush level with the rest of your basement. We make sure we thoroughly tidy up the area, so that your basement is ready to be enjoyed once again!
If your house is being affected by wet basement problems, and unappealing and unhealthy damp and mold, then our interior basement solutions can provide you with a highly effective and cost efficient solution that will clear up the mess and leave you with a warm, comfortable, and cosy home.
