Pennington Borough is a charming small community in Mercer County with a historic downtown and a mix of older homes and newer residential neighborhoods. The borough's older housing stock includes many homes with stone and block foundations that have been subject to decades of moisture exposure, freeze-thaw cycling, and soil movement.
Pennington's position in the Mercer County uplands means that drainage patterns vary significantly across the borough. Homes on lower lots near local streams experience high groundwater, while properties on higher ground deal with surface water runoff that concentrates against foundation walls.
Common Waterproofing & Foundation Challenges in Pennington, NJ:
- Older stone and block foundations in historic homes with deteriorated mortar
- Variable drainage across the borough from upland to low-lying areas
- High groundwater near local streams and drainage corridors
- Surface water runoff that concentrates against foundation walls on sloped lots
- Freeze-thaw damage to aging foundation materials
