Basement Waterproofing Calgary
A Dry Basement Is the Starting Point
Calgary’s clay soil expands when wet and contracts when dry, putting constant pressure on your foundation. We stop water before it becomes mold, damage, or a $50,000 problem.
Water doesn’t just damage drywall. It destroys equity. Mold can form within 24 to 48 hours of moisture exposure, and Calgary’s freeze-thaw cycles create new entry points every spring.
Interior drainage systems, sump pump installation, and exterior membrane application are the three pillars of a permanently dry basement. We assess your foundation’s specific conditions. Soil type, water table, grading. And build a solution that addresses the root cause, not just the symptoms.
Every waterproofing project includes moisture testing, crack injection, vapour barrier installation, and drainage routing to a code-compliant sump pit. We don’t guess. We test, measure, and engineer.
