What Drives Waterproofing Needs in Philadelphia, PA

Local Conditions That Drive
Interior Drainage System Needs in Philadelphia, PA

Waterproofing isn't one-size-fits-all. An approach that's effective in one region can be completely wrong for another. Knowing the local factors is part of what makes SJ Waterproofing Pros effective in Philadelphia, PA.

How Philadelphia, PA Weather Affects Your Foundation

Philadelphia, PA receives weather cycles that regularly saturate the soil around foundations — and that accumulated ground moisture works into structures through any pathway available. The process is cumulative — but the deterioration that results are often discovered only after years of slow progression.

The Philadelphia area has its share of serious storm events that overwhelm drainage systems. Residents in this part of PA often know from experience that specific weather events mean checking the basement.

Soil Conditions & Foundation Types in Philadelphia, PA

The soil composition common in this part of PA directly determines how water behaves near foundations. Clay-dominant ground conditions, which are prevalent throughout much of PA, hold water for extended periods and push it sideways against below-grade structures. Understanding what you're dealing with underground is step one of any credible waterproofing diagnosis.

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