Does Scoring Concrete to Prevent Slipping Affect Its Durability in Winter

Scoring concrete—adding grooves or texture to prevent slipping—is a common safety measure, especially for stairs and walkways. But while this rough surface may enhance grip during icy conditions, it introduces important considerations regarding the durability of the concrete itself, particularly when exposed to repeated freeze-thaw cycles. These cycles occur when moisture enters the surface, freezes, expands, and then thaws—only to refreeze again. Scored areas, with their increased surface area and exposure, are especially vulnerable to this repeated stress, which can accelerate cracking, chipping, and long-term surface degradation.
