Waterloo Barrier - Quality Assurance and Control Services

Potential leak paths through the Barrier are limited to the sealed joints. Therefore, the joints are the focus of the quality control procedures. Joints are inspected before the sealing operation to confirm that the complete length of the cavity is open and can be sealed. Video inspection equipment can be lowered into each clean cavity to provide a permanent visual record. Each joint is sealed from bottom to top facilitating the emplacement of sealant into the entire length of the joint. Proven procedures can be initiated to clear identified blockages within the interlocks prior to the sealing process. C3 provides trained inspectors to perform the quality assurance and control during the sheet pile installation and interlock sealing phases. The Quality Assurance and Control program is rigorous and unique to the Waterloo Barrier® and is an integral part of our certification of the system.
