Century-old Philadelphia foundations require specialized parging to combat efflorescence and spalling. Our cementitious coatings are reinforced with crystalline waterproofing agents that actively seal new cracks—critical for homes near the Schuylkill where hydrostatic pressure is high.
For stone foundations in Germantown, we apply breathable lime-based parging that mimics historic appearance while providing protection. All work includes interior drainage systems when needed, routed to sump pumps with battery backups for power outages during hurricanes.
