Exterior Waterproofing in Mississauga

Project Overview.

A Mississauga homeowner was dealing with persistent moisture problems in their basement, particularly during the rainy seasons, which led to concerns about mold growth and structural damage. Seeking an effective long-term fix, they turned to Aquatech for a full exterior waterproofing solution – excavating around the foundation, applying a waterproof membrane, and upgrading the drainage system to keep the basement dry for good.

Challenges:

Persistent Seasonal Moisture: Recurring dampness during rainy seasons raised concerns about mold growth and long-term structural damage.
Undocumented Foundation Damage: Excavation revealed previously hidden deterioration in the foundation that required structural repair before waterproofing could proceed.
Inadequate Existing Drainage: The property’s original drainage system wasn’t managing surface and subsurface water effectively, allowing moisture to build up near the foundation.
Restoring the Property Afterward: Landscaping needed to be carefully restored to its original condition while still improving grading for better water runoff.

Materials Used

Aqua Bloc 770-06 waterproof membrane
Yellow Jacket fibre mesh reinforcement
Hydraulic cement for structural crack repair
Closed-cell spray foam insulation
4″ x 100′ corrugated drain pipe with filter sock
Termination bar for membrane edge sealing

Solutions Implemented:

Initial Assessment: Conducted a thorough inspection of the home’s exterior to identify the sources of water intrusion and evaluate the condition of the existing drainage and foundation.
Excavation and Surface Preparation: Excavated around the foundation perimeter to expose the affected walls, then cleaned and prepared the surfaces for treatment.
Structural Repairs: Addressed previously undocumented foundation damage and deterioration discovered during excavation, restoring the foundation’s integrity before waterproofing.
Waterproof Membrane Installation: Applied a durable waterproof membrane to the exterior foundation walls to prevent external water from entering the basement.
Drainage System Enhancement: Upgraded the existing drainage system with new weeping tiles and proper grading to efficiently divert water away from the foundation.
Final Coatings and Insulation: Applied additional waterproof coatings over the membrane for protection against mechanical damage, along with thermal insulation to improve energy efficiency.
Backfilling and Landscape Restoration: Backfilled the excavated areas and carefully restored the landscaping to its original condition, with improved grading for water runoff.
