A water-retaining tank needs a lining or membrane selected for the tank material, the stored water and the conditions of service. Preparation and detailing at construction joints, corners and pipe penetrations are central to the scope. Product suitability for the particular application should be confirmed before any installation or return to service.
For an existing tank, an inspection should distinguish a local defect from widespread coating failure. Cracking, movement, previous repairs and the condition of the substrate all influence preparation and the repair method. Access, isolation and the required return-to-service sequence need to be planned with the work. Waterseal’s water retention and fire tank waterproofing page describes this service area.
Match the lining to the tank
Water-retaining tanks need systems selected around the tank material, retained water, exposure and intended use. Preparation of the substrate and continuity at construction joints, corners and pipework form part of the scope. Product suitability must be checked for the particular application before installation.
For an existing tank, inspection should consider failed coatings, movement, cracking and the condition of retained material. Removal, substrate repair, detailing and return-to-service requirements need to be planned together. A defined remedial scope helps distinguish a local defect from a system that requires wider renewal.
