Foundation Wall Replacement with HSS Reinforcement (Hamilton)

On exterior, dig down to existing footings by hand throughout entire proposed repair area and remove and dispose of existing damaged block foundation walls and footings in sections. Once removed in sections, form new concrete footings with rebar and connect fresh footings into existing structure.

Repeat the above process around entire perimeter of proposed repair areas. Once full perimeter rebuild is complete, prime walls and apply rubberized membrane to repair area.
