A leaking reservoir or water tank wastes water and damages the surrounding structure. Whether you have a domestic water tank, an irrigation reservoir on a smallholding near the Cradle of Humankind, or a storage facility near Walter Sisulu National Botanical Garden in Roodepoort, a failing lining needs to be fixed before the concrete deteriorates. Call 081 016 3479.
When You Need Reservoir Waterproofing
Reservoir and water tank waterproofing is needed when you notice water loss that doesn’t correspond to usage, visible cracks in the tank walls or floor, concrete that is damp on the exterior of the tank, or when an original lining is showing signs of delamination, cracking, or surface breakdown. Concrete tanks are inherently porous, they need a proper waterproof lining to contain water without leakage and without concrete products leaching into the stored water.
Our Reservoir Waterproofing Process
We drain and clean the reservoir, removing all loose material and treating any active cracks with a hydraulic cement plug. Surfaces are prepared to achieve adequate bonding. For potable water applications, we apply a food-safe crystalline cementitious coating or food-grade epoxy lining, both rated for contact with drinking water. Non-potable irrigation reservoirs may use bituminous coatings. Joints and corners receive reinforcement bandage before coating to prevent future cracking at transitions.
