The Delaware Valley's original builders used whatever stone they could haul - leading to unstable rubble foundations in Queen Village and Old City. Our patented helical tie-back system reinforces walls without disturbing historic finishes.
For severe bowing in Society Hill carriage houses, we install discreet carbon fiber grid reinforcement. Permeable hydraulic lime injections stabilize loose mortar while allowing natural moisture transfer. We won't cover problems with parge coating like some contractors - we fix the root cause.
