This is gradual — but the damage it causes are often discovered only after years of slow progression.

The Allentown, PA communities like Allentown has its share of serious storm events that overwhelm drainage systems. Residents in this part of PA understand firsthand that a hard rain season usually mean a wet floor.

Soil Conditions & Foundation Types in Allentown, PA

The ground conditions common in this part of PA shapes how moisture moves and builds pressure underground.
