Is your concrete foundation cracked or leaking? Most homeowners have encountered the frustrating problem of foundation cracks in their basement walls, as well as the resulting stubborn water leaks. Unfortunately, many foundation crack repair techniques deal solely with covering the cracks with hydraulic cement, epoxy or sealer. When moisture eventually loosens the water soluble ingredients and expansion and contraction takes place, these quick fix solutions usually fail. We know that cracks will continue to move as warmer and colder weather causes continuous expansion and contraction of the structure.
If your foundation is in good condition but has 1 or more cracks, the easiest way to permanently seal the crack is from the inside or exterior of your building using a step by step process. Should you have many cracks in your foundation or if you have a concrete block foundation, you may want to consider a full French Drain for your home. Please visit our French Drains page for more information.
Step 1:Drill holes through the crack at a 45 degree angle every 6 inches.
Step 2:Screw in injector plugs with grease nipples to connect with the high pressure pumps.
Step 3:Flush out the crack with a mild acid to remove dust, dirt & debris from one injector to the next (Removal of any obstructions for the injection)
Step 4:Flush out the crack with water to clean out the acid. Water is also a reactor/accelerator for the Polyurethane
Step 5:Cover the crack with hydraulic cement to prevent the outflow of the Polyurethane from the injection.
Step 6:Inject the Polyurethane at 3000 to 10000 PSI to fill all the open voids in the concrete and to push through to the other side.
