Interior Waterproofing in Toronto

Project Overview.

A Toronto homeowner was facing persistent dampness and water seepage in their basement walls. Because of this, they grew concerned about structural integrity, mold growth, and air quality. As a result, they reached out to Aquatech for a full interior waterproofing solution designed to combat moisture intrusion and protect the home’s lower level for good.

Challenges:

Persistent Dampness and Seepage: Water was seeping through the basement walls, raising concerns about structural integrity and indoor air quality.
Risk of Mold Growth: Ongoing moisture created ideal conditions for mold, threatening both the home and the family’s health.
Tight Spaces and Existing Infrastructure: The basement’s layout made installing a full drainage system more difficult than usual.
Multiple Moisture Entry Points: Cracks and joints throughout the basement needed careful sealing to fully stop water intrusion.

Materials Used

Hydro Guard Pro Series water barrier
DMX Drain 5M interior drainage system
Liberty sump pump
Sump pit
Polyurethane sealant for crack and joint sealing
Delta-MS dimpled membrane

Solutions Implemented:

Initial Assessment: We inspected the basement thoroughly to assess the water damage and identify the main moisture entry points.
Installation of Water Barriers: We installed resilient water barriers on the interior basement walls to block external moisture from getting through.
Sealing Cracks and Joints: We sealed every crack and potential entry point with hydrophobic sealants, ensuring a fully watertight basement.
Internal Drainage System: We integrated a French drain system around the basement perimeter to collect and redirect moisture into a new sump pump.
Sump Pump Installation: We installed a sump pump to actively remove collected water, keeping the basement dry and free of standing water.
Dehumidification: Finally, we set up a powerful dehumidifier to continuously manage moisture levels and improve air quality.

After we completed the project, the basement stayed completely dry, even through heavy rain. The pooling issue was gone, and the new drainage system now handles water quietly in the background.

Because of this, the homeowner no longer worries about mould or long-term damage to their foundation. Their basement is fully protected against Markham’s unpredictable weather. The work is backed by Aquatech’s lifetime warranty, giving them lasting confidence in the results.
