How Newtown Square, PA Weather Affects Your Foundation

Foundation Types Common in Newtown Square, PA Properties

The soil type in the Newtown Square, PA area directly determines how water behaves near foundations. Clay-heavy soils, common in many Newtown Square, PA communities, hold water for extended periods and push it sideways against below-grade structures. Understanding what you're dealing with underground changes everything about what solution will actually work.
