Residential Foundation Vertical Crack

Originally built in 1988, This hillside home in Portland, OR was experiencing cracking in the exterior foundation wall.

The Challenge

A homeowner contacted Foundations First NW after discovering a significant crack running across the basement floor slab. The irregular, expanding crack not only raised concerns about the structural stability of the concrete, but also presented a long-term risk of moisture intrusion and trip hazards. The homeowner needed a permanent, cost-effective solution that wouldn’t involve tearing out the entire slab.

The Solution

The team recommended Crack Stitch as the most efficient and economical repair approach. First, they laid out a staggered pattern of stitches perpendicular to the crack, ensuring load forces would be redistributed evenly across the repair. Each stitch was set into cut slots and bonded with structural epoxy. After stitching, the remaining visible crack was filled with epoxy to seal it against future water intrusion and to bond the separated sections of concrete together.

The Result

The Crack Stitch system provided immediate stabilization and long-term durability for the damaged floor slab — all without the need for full replacement. The stitches permanently tied the slab together, while the epoxy prevented further separation or expansion. The homeowner now has a structurally sound, safe basement floor — and peace of mind.

Why Crack Stitch:

Crack Stitch offers a highly effective method for repairing structural cracks in concrete foundations and slabs. Its ease of use and proven durability make it an ideal solution for both residential renovations and new construction projects, especially when long-term reliability is essential.
