Traditionally, concrete water tanks have not incorporated a waterproofing system until a problem has surfaced. If they were waterproofed, it was by using an external membrane, which was vulnerable to punctures, tearing and breakdown over time. Cracks have been filled with Oakum to stop water flow, epoxy coatings have been applied or polyurethane plastic liners have been welded together inside the tank to block water leakage.
While these methods may have provided temporary relief, none have been proven as effective as integral crystalline waterproofing. Cracks and defects repaired with crystalline systems such as Kryton’s Krystol Crack Repair System will outlast traditional epoxy or urethane repairs. When Kryton’s Krystol Internal Membrane (KIM), a crystalline admixture, is added directly to the concrete, a permanent waterproof shield is created. Crystals will form upon contact with water or moisture, filling the voids and capillaries in the concrete to block the ingress of water and contaminants. Krystol Internal Membrane will only grow stronger over time, and will not need to be replaced, saving future expense. By eliminating the time and costs associated with installing conventional membranes, KIM has enabled builders to meet tight timeframe and financial obligations. Investing the time to research, compare and select the best waterproofing system for water tanks provides peace-of-mind to the community by knowing their water supply is safe and healthy for many years to come.
