Actively leaking hairline concrete cracks as narrow as 0.02" in width can be repaired using this kit. Hydra Stop 300 reacts with moisture to expand inside the crack and stop the leak. Drill in place packers are used to inject the polyurethane resin into the crack. This is a single component material so no accelerator is needed to make it foam. The 3/8" injection packers have a premium rubber sleeve that reduces leaking as the polyurethane expands. This kit includes premium Hydra Stop 300 expanding foam. Use this kit on any concrete foundation crack that is too narrow for the low pressure method or if it is actively leaking water. High pressure concrete crack injection is done by drilling the packers into the crack and using a grease gun to inject the material at up to 1500 psi. Extremely tight cracks can be repaired with this method. Also cracks that are full of dirt and debris.
