Diesel Bund Linings Lincolnshire This brick built diesel bund was one of many at this location. Project Linings Ltd were contracted to ensure they were all of the correct size and watertight. We could have used various coatings or screeds to carry these works, but they couldn't the promise the longevity of our fibreglass lining system. A system we can guarantee watertight for 25 years. The internal brick wall and concrete floor surfaces were cleaned and keyed by sandblasting before we hand applied a double skin fibreglass lining system to the bunds internal surfaces.
