Scope of works
Surface Preparation Works – All external surfaces were subjected to a high-pressure clean-down to remove contaminants, debris, and surface deterioration. Concrete Repairs to Structural Ring Beam- Structural elements suffering from wear and minor damage were mechanically removed and repaired using high-performance cementitious repair mortars. Crack Injection- All the joints between the wall panels were crack injected to stop the treated water from leaking out of the tank. External Joint Filling- All joints between panels were solid filled and a protective coating was applied over. All roof joints and cracks were address with joint sealing solutions to stop water ingress. Movement Joint and Crack Sealing- All of the roof joints and cracks were solid filled and then a bandage system was applied to allow movement, while stopping any water ingress. Roof Surface Protection- The roof received a flexible, protective coating to resist environmental damage and extend the life of the concrete. External Protective Coating- The walls of the tank received a protective coating which will protect the tank from the harsh elements. Design & Installation of Steel Tension Bands- AQL designed and installed steel tension bands to help prevent any further movement or cracking within the tank
