Waterproofing Water Tanks

DESCRIPTION

Concrete water tanks are not naturally waterproof. Weather it be a crystalline product or an exterior sealing, if the surface is not prepared properly then failure is inevitable. One of the greatest challenges of working with concrete is cracking. Concrete cracks generally occur for one of three reasons: changes in volume due to drying shrinkage, direct stress due to applied loads or flexural stress due to bending.  Whenever the stress within concrete to pull apart exceeds the strength of the concrete to hold itself together, the concrete will crack.  The best way to protect a concrete structure and achieve an effective, watertight seal is to combine a quality concrete mix with an effective concrete waterproofing system.
