Concrete Floor Repair & Joint Protection

Concrete Floor Repair & Joint Protection

Joint Protection

Industrial & warehouse floors often break down at the control joints. This can be due to slabs that are rocking (see Slab Stabilization service for more info) or from heavy forklift traffic.

Floor Repair

Spalled concrete is concrete that is chipped, cracked, and deteriorating. This often happens right at a joint. The best way to fix these is with an epoxy or polyurethane mortar. The fastest way to repair a spall is to use a quick curing polymer resin mixed with a special blend of oven dried sand.  While most materials do require overnight cure……we do carry materials that are traffic ready in 10 minutes!

Joint Protection

Assuming the slabs are not moving, the solution to prevent further damage is to fill the joint with a semi rigid joint filler.  Both epoxy and polyurea joint fillers are manufactured specifically to support the sidewalls of the joints and bridge the gap that currently allows the traffic to deteriorate the joint edge. Don’t confuse these materials with caulking or joint sealers that are only applied at the surface. These are full depth materials that are strong enough and flexible enough to withstand continuous heavy wheel traffic but not so rigid as to weld the joint together.   Joint fillers should always be shaved flush immediately after cure.  Polyurera joint fillers allow for faster turnaround with cure times of an hour or less.
