one method of crack repair is called polyurethane crack injections, where we fill the cracks in your foundation walls with polyurethane foam, completely sealing the foundation wall crack from the inside of your home. All interior crack repairs are backed by our 10 year warranty. We begin the process by examining the crack which needs to be repaired in the foundation wall.
Next, we lay down plastic material to keep our work area clean, we immediately begin working on cleaning the crack with a wire brush. We mark port locations every 8″ starting from the bottom of the crack up to the top staggering each port on either side of the crack.
Next, we begin the port installation. We drill each port location at a 45 degree angle to ensure we have intercepted the crack in the center of the foundation wall and hammer in our ports. Following the port process, we attach nipple couplers to the ports this allows the polyurethane to enter into the port via a high pressure gun, Then with a two cartridge gun, we start at the bottom port and dispense a quick reacting polyurethane until it starts to come out of the next port. This process is repeated up the wall until the entire crack has been sealed. When the polyurethane has completely dried, we knock the ports off the wall using a hammer. Lastly we seal the crack face with a waterproof polyurethane sealant for a clean smooth aesthetically pleasing repair.
