The technicians chose Spetec PUR F400 for the repair. This polyurethane-based material has a closed-cell structure that seals cracks and joints. It remains flexible after curing, which allows for structural shifts. The material is NSF-certified, meeting environmental standards for water-related applications.
Due to the leak's unknown location, a comprehensive approach was necessary. The team injected the solution into all of the control joints and treated any visible hairline cracks within the concrete. The entire process was completed in two days, minimizing operational disruption.
The treatment showed noticeable effects in the control joints. After the procedure, the company refilled the pit. The results met their expectations. Construction at the facility resumed without further delays. The solution effectively addressed the water loss issue while maintaining the structural integrity of the cooling tower lift station.
