Why Swarthmore, PA Properties Need Basement Waterproofing

Local Conditions That Drive
Basement Waterproofing Needs in Swarthmore, PA

Waterproofing isn't one-size-fits-all. A solution designed for one foundation design can be completely wrong for another. Our crews understand the specific conditions that drive water problems in Swarthmore, PA — and in Swarthmore specifically.

Rainfall, Storms & Seasonal Moisture in Swarthmore, PA

Swarthmore, PA receives weather cycles that regularly saturate the soil around foundations — and the hydrostatic pressure that builds against foundation walls works into structures through any pathway available. It builds slowly — but the deterioration that results compound every wet season.

The Swarthmore area is no stranger to heavy rainfall periods that push sump pumps to their limits. Property owners in Swarthmore have learned the hard way that a hard rain season usually mean a wet floor.

What Swarthmore's Ground Means for Your Basement

The soil composition common in this part of PA directly determines how water behaves near foundations. Clay-heavy soils, common in many Swarthmore, PA communities, build up hydrostatic pressure that cracks and infiltrates even solid concrete over time. Knowing the ground composition around your Swarthmore property is step one of any credible waterproofing diagnosis.

Swarthmore and surrounding Swarthmore, PA communities contain buildings from multiple eras with very different waterproofing realities. Structures predating modern waterproofing codes frequently have drainage systems that weren't sized for current rainfall intensity. Our Swarthmore, PA technicians are familiar with every foundation type common in this area.
