Local Conditions That Drive
Basement Waterproofing Needs in Philadelphia, PA

Waterproofing isn't one-size-fits-all. What works in one climate and soil type can be completely wrong for another. Our crews understand the specific conditions that drive water problems in Philadelphia, PA — and in Philadelphia specifically.

How Philadelphia, PA Weather Affects Your Foundation

Philadelphia, PA sees weather conditions that create real, recurring pressure on below-grade structures — and the hydrostatic pressure that builds against foundation walls pushes against basement walls and floors with real force. It builds slowly — but the deterioration that results are often discovered only after years of slow progression.

The Philadelphia area is no stranger to heavy rainfall periods that push sump pumps to their limits. Residents in this part of PA have learned the hard way that a hard rain season mean checking the basement.

Soil Conditions & Foundation Types in Philadelphia, PA

The soil type common in this part of PA directly determines how water behaves near foundations. Clay-dominant ground conditions, which are prevalent throughout much of PA, build up hydrostatic pressure that cracks and infiltrates even solid concrete over time. Identifying your specific soil type is why our assessments start outside the building, not inside the basement.

Philadelphia and surrounding Philadelphia, PA communities contain properties spanning decades of construction. Properties built decades ago throughout Philadelphia often lack adequate below-grade moisture protection. Our Philadelphia, PA technicians have worked on every era of construction throughout Philadelphia and Philadelphia, PA.
