Concrete Repair & Chemical-Resistant Flooring

Most concrete jobs start with loss. Spalled slabs, cracked walls, and deep voids expose rebar and weaken floors, channels, and openings across a plant. Once reinforcing bar is exposed it corrodes and swells. That swelling cracks the surrounding concrete and drives the next round of spalling. A patch over rusty steel buys you weeks, not years.

AAS rebuilds and resurfaces damaged concrete cold, from crack patching to bulk-fill deep repair, using the Belzona 4000 Series of cold-cure compounds. Where rebar is exposed, the crew cleans the steel and primes it before rebuilding the cover. That stops the corrosion cycle that caused the original spall. We restore weathered stone and decorative masonry to the original profile. We reseal expansion and building joints with a flexible compound that bonds to concrete, stone, and brick and flexes with the joint. No breaking out, no recasting, no waiting on a fresh pour to cure.

Process areas and containment zones take punishment that ordinary toppings cannot answer. Acid, alkali, and mechanical attack strip the floor and let product reach the substrate. Acid eats into retaining walls, drains, and channels. It thins the concrete and opens leak paths into the ground around the unit. Bund walls spall from the inside out, expose rebar, and lose the rated volume they are supposed to hold.

AAS lays a chemical-resistant floor system over prepared concrete or steel, sized to the worst-case spill chemistry and the forklift and impact load on top. We line acid-retaining walls, drains, and channels so the structure holds the acid stream without breaking out the slab. On bunds, the crew rebuilds the spalled face, caps it with a barrier coating, and adds a chemical-resistant overlay where the service calls for it. We can match the system to the exposure, including hot acid service. Where the concrete contacts drinking water, we repair and coat with materials certified safe for potable-water contact, so the tank or channel returns inside the utility's planned outage.

Concrete that carries traffic fails where the traffic concentrates. Forklift wheel paths, loading-bay edges, and joint shoulders crater under constant load. The slab breaks up and material handling slows. Outdoors, sidewalks and exterior slabs crack and spall each freeze-thaw cycle and widen into trip hazards and liability. Elevator pits collect groundwater, lubricant, and cleaning chemicals that pool near electrical components.

AAS rebuilds worn loading bays and resurfaces high-traffic floors with a hard-wearing topping, and the bay reopens to forklift and pallet traffic within the shift. Exterior slabs and sidewalks get a weather-durable composite that bonds to damp concrete and reopens within hours. Spalled elevator pits get rebuilt and sealed with a chemical-resistant lining, and the car returns to service inside a maintenance day.

Every one of these repairs is cold-cure work. There is no welding, no hot-work permit, and no heat soak on a structure that has to keep its shape. That matters most in live process areas where a flame is the last thing you want near the product.

The payoff shows up on the maintenance schedule. Floors and bunds return to service in a shift or a planned outage instead of a multi-day recast. Rebar gets protected before it spalls the patch off, so the repair holds and the asset earns more years before it needs capital replacement. Acid stays in the channel, product stays in the bund, and water stays out of the pit. AAS prepares it, rebuilds it, and protects it, then the crew hands the unit back working. Twenty-four-hour on-call service covers the failures that do not wait for the next outage, and our safety record reflects a crew that gets the work done without incident.
