A leaking water tank does more than waste water — it corrodes reinforcement, weakens the surrounding slab, and can contaminate the water supply. Unicorn Chemical treats both overhead and underground tanks with cementitious slurry and food-grade waterproofing coatings safe for potable water, engineered to withstand constant hydrostatic pressure from the inside. We first inspect for cracks, honeycombing and joint failure, repair structural defects, then apply a multi-coat system on all internal faces. Our tank waterproofing carries one of the longest warranty periods in our range because tank walls face continuous, not intermittent, water pressure.
