Slab Movement & Clay Soils
San Antonio’s expansive clay moves foundations. We assess and repair cracking before coating, rather than sealing a problem in.
San Antonio is home base for CB1 Specialty Concrete, and it’s where most of our work happens. That means the widest range of jobs we do: 1950s bungalows near the urban core with slabs that have shifted, new construction on the far North and West sides, medical and office buildouts along the 281 and 1604 corridors, and warehouse floors that have to take forklift traffic all day. As a local epoxy flooring contractor in San Antonio, we know what this area’s clay soils do to concrete over time — slabs move, cracks open, and coatings installed without proper repair fail early. We diamond grind, repair and profile every floor before a drop of product goes down, whether it’s a two-car garage in Alamo Ranch or 40,000 sq ft off I-35.
