Services
Basement Waterproofing
Our basement waterproofing solutions address water infiltration through foundation walls, floors, and joints. Using sub-floor drainage systems and exterior protection like Platon Foundation Protector, we prevent water damage while maintaining structural integrity. Services include weeping tile installation, sump pump systems, and crack sealing with polyurethane injection to create permanent, environmentally friendly repairs.
Foundation Replacement
When structural integrity is compromised, we perform partial or complete foundation wall replacement. Our trained staff executes this complex work with minimal disruption to homeowners, often allowing residents to stay during repairs. This service also creates opportunities for basement expansion in older homes with low ceilings.
Foundation Underpinning
We address foundation settlement issues caused by unstable soils through professional underpinning services. This prevents further structural damage from sinking foundations, bowed walls, and uneven floors. Our solutions stabilize existing structures while explaining the geological factors behind Ottawa's unique clay soil challenges.
Garage and Basement Floors
We replace worn concrete floors in garages and basements with new steel-troweled or broom-finished surfaces. Our team ensures proper mix design for each application, including control joints to prevent cracking. This service improves both functionality and property value through durable, code-compliant installations.
Window Well Excavation
Our window well excavation services address water accumulation problems around basement windows. Using ScapeWEL and StakWEL systems, we install proper drainage while maintaining window functionality. This prevents water seepage through window wells caused by Ottawa's problematic clay soil conditions.
