Foundation Waterproofing
BASEMENT WATERPROOFING — EXTERIOR & INTERIOR SYSTEMS
Foundation waterproofing prevents water infiltration through basement walls and floors. Exterior methods include excavation, membrane application (sheet or spray-applied), dimple board drainage mat, and exterior drain tile. Interior methods include interior drain tile systems, sump pit and pump installation, crack injection, and vapor barriers. We diagnose the water source and recommend the most effective, cost-efficient waterproofing approach for your specific situation.

Why Choose Our Foundation Waterproofing
Basement waterproofing requires diagnosing the water source correctly first. Is it surface water, high water table, hydrostatic pressure, or condensation? The answer determines whether exterior waterproofing, interior drain tile, crack injection, or a combination is the most effective and cost-efficient solution. We diagnose before we prescribe.

1. Wet basement after rain
Water appears on the basement floor or walls during or shortly after rainfall events.

FAQs About Foundation Waterproofing
Interior vs exterior waterproofing?
Exterior is more effective (stops water before it touches the wall) but costs more and requires excavation. Interior drain tile manages water that enters and directs it to a sump pit. We often recommend interior systems because they're less disruptive and more cost-effective for most residential situations.
