Before and after: Old Masonry Repair & Waterproofing in Norwalk, CT


Norwalk crack problems are usually manageable when the wall, the water, and the slab are treated as one system instead of three separate issues. See our full foundation crack repair coverage in Norwalk →
The problem
Coastal Norwalk home with original older masonry foundation. The wall had developed deteriorated mortar joints, surface efflorescence, and active moisture transmission through the wall material itself. Period-correct repair required materials and technique appropriate to the older masonry rather than modern poured-concrete methods.
How we fixed it
We performed full masonry repair, rebuilding deteriorated mortar joints with a high-modulus structural mortar matched to the original. The masonry surface and joints were then sealed with a waterproofing system designed for older masonry walls, restoring the wall's ability to resist moisture transmission while preserving the structural character of the original construction.
