The Challenge: Leaking Underground and Overhead Concrete Tanks

Concrete water tanks are subjected to continuous hydrostatic pressure. In overhead tanks, structural shifting and weathering create cracks, causing water to drip down ceilings and damage adjacent walls. In underground tanks (sumps), leakages are dual-directional: water leaks out of the tank, and contaminated groundwater seeps in, bringing mud, germs, and organic wastes into your drinking water supply.

Normal cement coatings or plastic wraps degrade inside water tanks, releasing chemicals and scaling off. To seal your tank permanently and safely, you need a food-grade, non-toxic barrier coating that complies with health standards.

Our Water Tank Waterproofing Process

We follow a health-safe, non-toxic cleaning and coating process to seal concrete tanks:

01

De-watering & Pressure Cleaning

We empty the tank completely and high-pressure clean all interior walls, floor, and ceilings to remove dirt, mud, algae, moss, and chemical residues.

02

Crack Identification & Grouting

We identify all visible crack lines and seal them using polymer cement grout and non-shrink waterproofing compounds to withstand high water pressure.

03

Active Crystalline Base Coat

We apply a crystalline slurry coat over the damp concrete surface. The active chemicals react with concrete minerals to form deep micro-crystals, blocking all pores.

04

Food-Grade Epoxy Topcoat

We apply two coats of premium, non-toxic, solvent-free food-grade epoxy liner. This forms a smooth, glossy, easy-to-clean sky-blue finish that prevents mold growth and leakage.
