Substrate2 sumps
MaterialPrecast Concrete caisson bolted together and sealed with Rubber Gaskets.  The Rubber Gaskets had failed causing infiltration due to poor installation.
Purpose of the sumps Treatment of brewery waste products, including hops, yeast and barley
Significant preparation was required prior to spraying which took 5 days.
Sump 1 Approx size 4m dia x 4m deep
ConditionThe sumps was in reasonable condition with minimal infiltration. The surface had a previous coating which proved extremely difficult to remove.
PreparationHigh pressure power wash. The existing coating was then abraded to provide a suitable key for the epoxy followed by power wash again.
The entire surface was then acid etched and washed down with water prior to spraying.
Spraying1 coat at 6mm thick.
 Sump 2Approx size 7m dia x 5m deep
Condition The sump had extreme infiltration and the surface had a previous coating which proved extremely difficult to remove.
PreparationHigh pressure power wash. The existing coating was then abraded to provide a suitable key for the epoxy followed by power wash again.
Areas of infiltration were then drilled and an injection grout system applied to seal the leakages which included fast setting cement (waterplug).
The entire surface was then acid etched and washed down with water prior to spraying.
Spraying1 coat at 6mm thick.
