UNDERGROUND TANKS CONCRETE WATERPROOFING.

Concrete Waterproofing of underground tanks requires special skills and expertise to guarantee a lasting solution. A leaking or failing underground tank isn’t always easy to spot. You might not see any signs of a problem. Routine maintenance or an inspection can uncover a leaking tank, but most homeowners won’t be aware of a leak until it becomes a major problem.

Underground water tanks are susceptible to water ingress from external sources like surrounding soil as well as soluble salts can infiltrate the tank and cause reinforcement attack if not properly waterproof. Our vast comprehensive waterproofing solutions can keep your structure free from any harmful chemical attack.

The average lifespan of a concrete water tank is 10 to 15 years, during which the internal concrete walls must resist constant hydro-static pressure of varying degrees, and may also come in contact with chlorine and other chemicals that soften their surface. The areas of concern are: cold joints, failing water stops, penetrations, shrinkage cracks and voids that cause leakage.

An essential assumption for successful waterproofing is that the walls and floor of the reservoir are properly designed so that they are statically efficient to withstand the hydrostatic water pressure developed.

For the Underground tanks, the internal surfaces of the walls and floor are coated with a cement-based, brushable waterproofing cement Nitocote CM210 From Fosroc which provides a uniform and continuous, totally waterproof membrane, which is characterized by high strength and strong bonding to the substrate in order to withstand negative pressure. the Waterproof also ensures Strength and longevity due to the inorganic nature of the material.
