We at Aquatech provide rapid-response, 24/7 emergency waterproofing services directly to Oshawa and the surrounding Durham Region.

You should call our licensed foundation experts at Aquatech. A basement that takes on water after heavy rain is typically suffering from intense hydrostatic pressure pushing against failing exterior drainage or foundation cracks. We will accurately diagnose the intrusion point and install a permanent, lifetime-warrantied solution—such as an interior weeping tile system or exterior membrane—to safely redirect groundwater away from your home.

A musty odor in an apparently dry basement is a primary indicator of hidden moisture and early-stage mold growth. This occurs because porous concrete block and poured foundations allow water vapor to permeate the walls, even if liquid water is not visibly pooling. This vapor becomes trapped behind drywall or under flooring. We utilize advanced moisture-detection equipment to locate these hidden damp zones before they compromise your indoor air quality.

Yes, peeling, bubbling, or flaking paint on basement walls is a classic symptom of moisture infiltration. As hydrostatic pressure forces water vapor through the exterior foundation wall, the moisture pushes against the interior paint layer, causing it to lose adhesion. You may also notice a white, powdery substance called efflorescence. We at Aquatech can permanently resolve the underlying moisture issue so your basement walls remain dry and structurally sound.

• Interior Waterproofing: This is a water management system. We install a perforated weeping tile pipe and drainage membrane beneath your basement floor slab to catch water as it enters and safely channel it to a sump pump. It is highly cost-effective and avoids yard excavation.

• Exterior Waterproofing: This is a water prevention system. We excavate the earth around your foundation to the footing, clean the walls, and apply a thick, impenetrable elastomeric membrane and dimple board. This permanently stops groundwater from ever touching your concrete walls.

The average cost for isolated foundation repair in Oshawa is $400 to $800 per structural crack. We at Aquatech perform these repairs using advanced polyurethane or epoxy resin injections that expand deep within the wall to create a flexible, watertight seal. For extensive structural bowing or deteriorating masonry requiring carbon fiber reinforcement or excavation, costs can range from $2,000 to $6,000+.

Older homes in Oshawa often feature deteriorating block foundations and lack modern weeping tile systems. Because they usually require more comprehensive intervention, the price range typically sits between $5,000 and $12,000. Upgrading an older home to safely handle today’s heavy rainfall often requires installing a brand-new interior weeping tile perimeter and a heavy-duty sump pump. We back all these structural upgrades with our 25-year transferable lifetime warranty.
