We walk you through the completed system, explain maintenance, and provide your written lifetime warranty documentation.

Waterproofing Systems We Install

Interior Drainage Systems

Sub-floor drainage channels that capture water before it reaches your floor and direct it to a sump pump. The most effective solution for most Philadelphia-area homes.

Exterior Waterproofing

Full excavation and application of waterproof membrane to the exterior foundation wall. The most comprehensive solution for severe water problems.

Wall Crack Injection

Polyurethane or epoxy injection to permanently seal poured concrete wall cracks from the inside — no excavation required.

Sump Pump Systems

High-capacity sump pumps with battery backup to ensure your basement stays dry even during power outages and heavy storms.

Vapor Barriers

Heavy-duty vapor barriers applied to walls and floors to block moisture migration through concrete and block walls.

Window Well Drains

Proper drainage for basement window wells to prevent water from pooling and seeping through window frames.
