Water Tank Waterproofing Services Hyderabad | GK Waterproofing

Water Tank Waterproofing in Hyderabad

 

Water tank waterproofing is a chemical treatment applied inside and outside an overhead tank, underground sump or Sintex/RCC storage tank to seal cracks and porous concrete so stored drinking water does not leak out or get contaminated by soil moisture, salts, or seepage. GK Waterproofing uses food-grade, potable-water-safe waterproofing compounds for every tank and sump treated in Hyderabad, with a 10-year warranty.

 

Understanding the Problem

 

Water tanks and underground sumps face a leakage problem from two directions at once: from the inside, constant water pressure pushes against the tank walls and floor searching for the smallest pore or crack; from the outside, soil moisture and dissolved salts attack the concrete, gradually eating away at it. An untreated or poorly-waterproofed tank slowly loses stored water — pushing up your monthly water tanker or bore-well costs — while damp patches appear on the outer walls, and in the worst cases dirty groundwater or soil contamination can mix into your drinking water supply. Because tanks and sumps are hidden underground or on the terrace, most owners only notice the problem once water bills spike, walls near the sump feel damp, or a foul smell appears in the stored water.

 

Common Causes & Warning Signs

 

• Cracks in RCC tank walls or floor caused by construction shrinkage or settlement
• Porous, poor-quality concrete that lets water seep through slowly
• Corroded or leaking pipe inlets, overflow pipes and outlet valves
• Missing or failed internal waterproof plaster/coating from original construction
• External soil pressure and salt attack on underground sump walls
• Age-related deterioration in tanks over 8–10 years old

 

 

Our Process

 

Draining & Inspection: The tank or sump is fully drained, cleaned, and inspected for cracks, honeycombing, and pipe-joint leaks.

 

Surface Preparation: The internal surface is chipped, cleaned and roughened to remove loose material and ensure a strong chemical bond.

 

Crack Injection & Repair: Structural cracks are injected with a polymer-modified grout to seal the leak path from within the concrete.

 

Food-Grade Waterproof Coating: A potable-water-safe (non-toxic) waterproofing coating is applied in multiple layers on the internal walls and floor.

 

External Waterproof Treatment (for sumps): The outer surface of underground sumps is also treated to block soil moisture and salt attack from outside.

 

Curing & Water-Fill Test: The tank is left to cure fully, then filled with water and monitored for 24–48 hours to confirm zero leakage before final handover with warranty.

Understanding the Leakage Problem - and How We Solve It

 

Water leakage in buildings almost never announces itself where the actual damage begins. A stain on a bedroom ceiling can trace back to a crack on the terrace two floors up; a damp bathroom wall can mean a failed membrane laid years ago beneath the tiles; a dropping water tank level can mean a hairline crack invisible from outside. This is exactly why GK Waterproofing Services starts every job with a genuine physical inspection rather than a guess — our engineers trace the leak to its real source, explain what caused it in plain language, and recommend the specific waterproofing method that actually solves it, not the cheapest quick-fix that only delays the same leak reappearing next monsoon.

• Protects the structural steel inside your RCC slab, walls and columns from corrosion
• Stops recurring monsoon-season damage to paint, ceilings and interiors
• Reduces long-term repair costs by fixing the root cause, not just the symptom

Frequently Asked Questions

 

Q. Is the waterproofing chemical safe for drinking water tanks?

A. Yes. GK Waterproofing uses potable-water-safe, non-toxic waterproofing coatings specifically approved for drinking water storage tanks and sumps, so treated water remains safe to use.

 

Q. How can I tell my underground sump is leaking?

A. Common signs include a noticeable drop in water level faster than expected usage, damp patches on the walls near the sump, or a musty or muddy smell in the stored water — all warrant an inspection.

 

Q. Can an old tank be repaired instead of rebuilt?

A. In almost all cases yes. Crack injection combined with a fresh internal waterproof coating can restore an old tank or sump to a fully leak-proof condition without demolition or rebuilding.
