Interior Waterproofing

Reducing the Amount of Mold and Moisture in your Basement Living Space

If you have excess moisture in your basement living space and start to find mold growing from your basement walls, interior waterproofing is the best way to reclaim your basement. Through the process of reducing the amount of moisture in your basement, you will notice a difference in the improved air quality and significantly reduced dampness of your living space. Leaky Basement provides interior waterproofing services to the Greater Toronto Area, including Toronto and Hamilton.

Our Leaky Basement team will use a combination of commercial-grade waterproofing materials in the interior waterproofing process:

  • Interior Drainage Membrane applied over your basement walls the top to help redirect excess moisture and water down towards the bottom of the foundation, where the drainage membrane is connected to a system of drainage pipes. This dimpled drainage membrane will collect the excess moisture that breeds mold and other bacterias, and prevent these harmful spores from going airborne in your basement.
  • Drainage Pipe System that runs along the footing of your basement walls and if possible, inside of your basement floor collecting the excess water that drains from the interior drainage membrane. The drainage piping will redirect the water to your basement drain or to a sump pump. The piping is placed in the trench and covered with 3/4 crushed gravel to further assist with drainage. Then the trench is re-cemented to cover the drainage tiles and gravel.

Waterproofing from Inside your Home is Another Option


When possible, Interior Waterproofing can be used instead for your foundation walls and ensure you will be leak free

When it comes to leaky basement waterproofing from the inside, homeowners can choose an internal system based on a few reasons. Sometimes, the work cannot be done from the exterior as there is not enough room or cost-effectiveness for basements that are unfinished. Another reason for using interior waterproofing is hydrostatic pressure, the water rising from the ground can be routed to a Sump Pump to discharge the water out of the house.

Sump pumps are the main component when it comes to internal systems. Sump Pumps are installed in a sump pit, water flows into the sump pit and/or it collects groundwater and then the pump will discharge it away from the basement. After the internal system is installed, any water that leaks in will then travel through the weeping tiles to the sump which will then be discharged as well.

The Internal System will add drainage inside your home which helps reroute the water flow to a point of discharge. Walls that are being penetrated by water will be drained out by the drainage membrane, which gives you a barrier between your living area and the wall. This can then be framed and finished on top to have a seamless drainage solution.
