EDINBURGH TANK REPAIRS
A new build Hotel in Edinburgh had suffered a catastrophic leak to the sewage tank in the basement. The tank had failed due to high pressure from the water table (ground water).
Attempted emergency repairs had resulted in around 2m² of the 20mm thick polyethylene tank wall being cut out.
It was assumed that the tank could be simply repaired by patching this area with GRP. The tank was, however, manufactured from polyethylene a material that is incompatible with polyester. It was then assumed that repairs could be affected by a PE specialist plastics company repairing the huge hole using polyethylene welding techniques. No company could be found that would undertake this repair far less offer a guarantee.
GRP Aberdeen Ltd were engaged by the main contactor to see if a repair could be achieved using GRP. The client had a deadline of 12 days before the hotel was due for handover. GRP Aberdeen Ltd surveyed the tank and produced a method statement for repair which was accepted by the client.
