The Delaware Valley's clay-rich soil causes chronic foundation movement. We employ helical piers and limestone mortar injections to stabilize compromised walls without full excavation. For Chestnut Hill's Wissahickon schist foundations, we source matching stone from local quarries.
Our process minimizes disruption to historic interiors - no need to move out during repairs. We install French drain systems where needed to manage groundwater. Every project includes a 10-year transferable warranty against vertical settlement.
