Cracking may be caused by over-loading a concrete slab, inadequate number of control joints, or slab shrinkage. Once identified, these cracks should be repaired quickly and correctly. If the crack is less than one inch, it can be routed and filled with polyurea.
If the crack exceeds more than one inch, then the crack must be rebuilt. In order to rebuild the crack area, the crack needs to be cut out at the widest point on both sides, and the area between the saw cuts is removed. Next the void is patched with a trowel grade epoxy mortar flushed with the existing slab.
Filling control joints in a concrete slab not only extends the life of a concrete floor, but also creates a smooth transition between the slabs. Joint filler can be used if the joint is less than one inch wide. By filling the joint with polyurea, this process will protect the joint edge from wheeled traffic damage
When a control joint exceeds more than one inch wide, then the control joint will need to be rebuilt. Rebuilding a control joint requires that we cut out the joint at its widest point on both sides, remove the area between the saw cuts, and patch the void with a trowel grade epoxy mortar flushed with the existing slab. Then the joint is cut back into the epoxy mortar and the new joint is filled.
Over time, all concrete floors will require some type of patching repairs. Daily usage from steel-wheeled carts, forklifts, pallet jacks and dropping materials will cause damage to your floors. Breakouts, both small and large, can cause a trip hazard for your employees. Several different material options are available. Patching concrete quickly reduces future downtime and additional repair costs.
Over time, high wear, chemical exposure and poor slab conditions all contribute to severe concrete erosion. To fix this issue, we apply an epoxy mortar on the affected areas of the concrete slab. Once applied, the epoxy is power troweled smooth and then typically a wear coat of 100% solids epoxy is applied.
Urethane caulks are installed on perimeter walls. This type of caulking is most often required by food and beverage operations. Urethane perimeter caulking is a must for facilities that need superior housekeeping.
Bolt Hole Repairs
Bolt hole repairs may be necessary if your facilities' racking is being reconfigured or if a tenant has vacated your building. If left unattended, these small holes may become larger holes and could potentially become trip hazards for your employees. The bolt is ground below surface and then overfilled with epoxy and ground smooth the following day.
Due to low temperatures, a specially formulated patch material is used to resurface and repair the needed areas in freezers.
Slab Curl Removal
Slab curl occurs when the surface of a concrete slab dries out before the entire slab, causing an elevation difference between the two slabs. The elevated joint edge is ground to remove curl.
