Interior Waterproofing in Scarborough

Project Overview.

A Scarborough homeowner was preparing to convert their basement into a rental suite when they noticed dampness along the walls during a routine inspection. Because a rental unit needed to meet a higher standard of dryness and safety, they turned to Aquatech for a full interior waterproofing solution – a drainage system and sump pump built to keep the space fully livable year-round.

Challenges:

Dampness Found Before Renovation: Moisture appeared along the basement walls just as the homeowner began planning a rental conversion.
Higher Standards for a Rental Suite: A future tenant’s living space needed to be completely dry and free of mold risk, not just “good enough.”
Working Around Renovation Timelines: The waterproofing needed to be completed quickly to avoid delaying the rest of the renovation project.
Long-Term Reliability: With a tenant depending on the space, the homeowner needed a solution built to perform for years without maintenance surprises.

Materials Used

DMX Drain 5M interior drainage system
Liberty sump pump
Sump pit
Hydro Guard Pro Series vapor barrier
Delta-MS dimpled membrane
Hydraulic cement for crack sealing

Solutions Implemented:

Priority Inspection: We inspected the basement quickly to identify every point of moisture entry before the renovation schedule began.
Interior Drainage System Installation: We installed a drainage system along the basement perimeter to intercept water before it could cause damage.
Sump Pump Installation: We installed a reliable sump pump to actively remove any collected water and keep the space dry.
Crack and Joint Sealing: We sealed all cracks and potential entry points to stop moisture from getting through the walls.
Vapor Barrier Application: Finally, we applied a vapor barrier to block moisture and create a rental-ready foundation for the renovation to continue.

After we completed the project, the basement stayed completely dry, giving the renovation team a clean, ready foundation to build the rental suite on top of. The new drainage system and sump pump now protect the space quietly in the background, with no risk of moisture interrupting the finished unit down the line.

Because of this, the homeowner could move forward with their rental conversion with full confidence in the space’s long-term dryness. The work is backed by Aquatech’s lifetime warranty, giving them added peace of mind as a landlord.
