120,000-Litre Underground RCC Drinking Water Tank Waterproofing in Manikonda
!
The Water Ingress Problem
A 120,000-litre underground reinforced concrete drinking water tank developed severe joint leaks. Water was seeping out through cold construction joints, contaminating the potable water supply with surrounding subsoil mud and depleting society water reserves daily.

Engineering Treatment & Execution
1. Complete dewatering, sludge extraction, and bio-wash de-algae treatment.\n2. Pressure routing of all cold construction joints and corner fillets with rapid-setting crystalline mortar.\n3. Pressure injection of microfine cementitious grout into porous honeycomb concrete zones.\n4. Dual-coat application of certified food-grade, potable-safe 2-component flexible cementitious polymer coating (CFTRI / WRAS compliant).\n5. 48-hour chemical curing followed by mandatory water quality potability lab testing.
Underground Water Tank Waterproofing: Ensuring Potable Water Purity
Waterproofing drinking water tanks and sumps demands specialized materials that are completely non-toxic, anti-microbial, and resistant to continuous positive and negative hydraulic heads.
Food-Grade Polymer Barrier
We executed a dual-stage treatment: deep structural crystalline injection to seal honeycombs within the concrete walls, followed by a certified potable-safe elastomeric polymer barrier that prevents algae growth and withstands 15 meters of water head pressure.
