Foundation Types Common in Greenvale, NY Properties

The soil composition in the Greenvale, NY area affects how quickly water intrusion happens and from which direction. Clay-dominant ground conditions, which are prevalent throughout much of NY, build up hydrostatic pressure that cracks and infiltrates even solid concrete over time. Understanding what you're dealing with underground changes everything about what solution will actually work.

Greenvale and surrounding Greenvale, NY communities have a wide range of housing ages and foundation types.
