Exterior slab and sidewalk repair
Sidewalks and exterior slabs crack and spall each freeze-thaw cycle, widening into trip hazards and liability exposure on public and plant grounds.
The need for exterior slab and sidewalk repair
BHI Coatings performs exterior slab and sidewalk repair across Alvin and the Texas Gulf Coast. Every freeze-thaw cycle takes a little more off a sidewalk or exterior slab. Small cracks widen into lips and craters, and those become trip hazards on public and plant grounds. An open trip hazard is a liability exposure that grows every season it sits unrepaired.
How BHI Coatings does exterior slab and sidewalk repair
We repair exterior slabs, sidewalks, and infrastructure surfaces with a weather-durable composite that bonds to damp concrete, so nobody stands around waiting for the substrate to dry out. Belzona 4181 and 4111 support the patching and resurfacing. The repair is cold-cure and feathered into the existing grade.
Typically applied with Belzona 4181, Belzona 4111, matched to the service conditions.
The walkway reopens within hours with the trip hazard gone, and the new surface takes weather and traffic without a full slab replacement.
