The joint filler in place.

Control Joint Filling

Control joints are cut into a slab at the time the concrete is placed to minimize random cracking. When concrete cracks it will follow the path of least resistance, typically at the control joint.

The control joints are filled to keep dirt, dust and other debris out. We use a two component polyurea process injecting the mix with a special caulk gun that has two chambers. We use a scraper to clean up the excess while it’s still tacky, making the filler flush with the floor. This product usually takes about 15 minutes to set up.
