OUR PROCESS
Interior Waterproofing (Inside Fix)
Exterior Waterproofing (Outside Defense)
Hybrid Waterproofing (Best Of Both, Smart On Cost)
Drainage Systems (Move Water Away First)
Good drainage is step one to a permanently dry basement. Before we recommend fixes, we trace the water’s path with a quick camera inspection, then correct the actual cause—not just the stain. In St. Catharines, that usually means giving water an easy exit: footing-level relief for groundwater, shallow channels for surface runoff, and safeguards for storms or sewer surges. Pair these with simple housekeeping—clean gutters, longer downspouts, proper grading—and your waterproofing system works better, lasts longer, and costs less to maintain.
