The geotechnical needs of DOTs and other agencies responsible for roads and bridges are vast. Issues include: Culvert repair Soil stabilization Void filling Concrete slab lifting Sinkhole remediation Slope control Slough control in tunneling
Protecting concrete usually means shielding it from the elements of nature or from harsh manmade chemicals. But it’s not just concrete that needs such protection. Corrugated metal pipe, steel surfaces, material hoppers, rail cars and masonry all can come in contact with corrosive or abrasive materials or harsh conditions.
Industrial floors often break down at the control joints. This can be due to slabs that are rocking or the constant hammering from heavy forklift traffic. (Read more information on slab stabilization.)
Spalled concrete is concrete that is chipped, cracked and deteriorating. This often happens at a joint. The best way to provide concrete crack repair is with an epoxy or polyurethane mortar. The fastest way to repair a spall is to use Floor Fix polymer resin and a mortar made with resin and oven dried sand. This material is traffic ready in 10 minutes. Prime Bond 3100 or Prime Bond 3900 also make a fantastic mortar if you have time for the material to cure (usually overnight).
Max Wall of Floor Consultants, Inc., specializes in repairing the floors of big box retail stores and distribution centers.
“The largest project we used Floor Fix on was Lowes in Valdosta, Ga. Our crew patched 18,000 1.5″ diameter holes 1.5″ deep,” says Wall. “We use 3000 for nosing repairs in every distribution center we work in. We use a lot of 5500 for its quick dry time and durability in every distribution center we work in. We’ve installed over a hundred miles of it.”
