| The Project |
Killingholme Power Station situated near Humberside is a Combined Cycle Gas Turbine (CCGT) comprising two 450MW modules giving a total generation capacity of 900MW.
EON, the company who operates the station contacted TAM to discuss an issue they had with one of the water outfall culverts which was experiencing ground leakage through one of the movement joints. |
| The Challenge |
The leakage into the joint was estimated to be in excess of 120 litres per hour. Continued loss of water meant degradation to the joint and most importantly, loss of fines to the rear of the structure.
The leakage was occurring at several locations around the joint and it was therefore necessary to design a system to control water loss around the full joint circumference. The remedial design had to take into account the access and limited working space within the culvert. |
| The Solution |
Removing the existing joint fibre board was impracticable and a temporary water cut off method needed to be proposed.
Ram Services undertook the works using TamPur 100 and introduced the polyurethane resin to the rear of the structure through drilled access holes positioned around the joint circumference. This fast reacting polyurethane resin provided a dry working environment allowing the application of a hypalon strip to be adhered to the face of the joint to act as the final waterproofing system. |
| TAM Contributory Success Factors |
TAM’s contribution
- Expertise and knowledge of movement joint configuration and leak sealing methods
- A wide selection of technically advanced materials
