Hi, and welcome to DryShield’s video on foundation crack injections. To ensure the highest quality seal, we drill out a 45-degree angle every 6-8 inches, alternating from side to side, hitting the centre of the crack. Steel ports – not plastic – are fastened into the holes. The ports are then injected with a polyurethane from bottom to top with hydraulic pressure. It is important steel ports are used, not plastic, to obtain adequate pressure to ensure the urethane is distributed evenly. The hydrophobic polyurethane expands 20 times its volume, to seal off all voids from front to back. An additional option is carbon fibre stripping. Cuts are made perpendicular to the crack, then carbon fibre strips are installed and coated with epoxy. This procedure typically takes 2 hours and DryShield provides a full 25-year transferable warranty. For more information, please continue reading our website (, or call us today at 1800-277-5411
