Joint System Rehabilitation
Concrete Power Plant Structure
Time, and the South Texas elements, had taken their toll on the joint systems at a Power Plant. Heavy seasonal rains caused infiltration into the structure despite continued maintenance efforts.
Based on their history of safety and performance in power plant structures, Jeans Waterproofing of Texas (JWTX) was contracted by the General Contractor to tackle the project. In conjunction with the project team, and under the careful supervision of the utility staff, JWTX was contracted to remove the weathered asphalt-filled joints and clean the surfaces to receive the new system. A high-performance polyurethane joint system was then installed to over a mile of prepared-substrate.
The perimeter joints on the roof of the concrete structure posed a particularly challenging problem to the construction team. Based on existing site conditions, the project-team developed a system to insure the long-term performance of these critical joints. The solution included a thorough cleaning and re-sealing of the joints, followed by a elastomeric sheet system. A UV-resistant elastomeric coating system was added to provide additional protection from the harsh environment.
The project was successfully completed on schedule ins spite of the scope additions and re-engineering required. The system continues to perform and the structure remains moisture-free.
