Epoxy Waterproofing
Food-neutral epoxy lining for water-retaining structures
Applications
ReservoirsSumpsOverhead tanksDucts and tunnelsDamsFood, dairy and process water tanks
Procedure
1
Clean the surface of dirt, dust, laitance, loose particles and other contaminants by wire brushing.
2
Seal leaks, joints and pipe sleeves first, and grout seeping concrete through drilled holes.
3
Apply two coats of CONPROOF EP with 3 to 4 hours between coats.
Important Suggestions
The surface must be completely free from dirt, dust, laitance, loose particles and grease. Use it on internal faces; it is not UV resistant.
Why This Treatment?
The two-component, solvent-free epoxy forms a hard, jointless, water-impermeable lining that seals porosity and fine cracks. Being food-neutral, it is safe where coated surfaces touch drinking water.
