Service Overview
Professional Overhead Tank Solutions in Rajahmundry
Overhead RCC water tanks sit on roof towers exposed to intense sun. Temperature fluctuations expand and contract the concrete, causing hairline cracks. Water leaks from overhead tanks directly penetrate terrace slabs, damaging top-floor rooms below.
When is this service required?
When overhead tank outer walls show wet patches, water levels drop overnight, or the terrace below stays wet.

Preparation & Execution

Answers Before You Book
Frequently Asked Questions
Why does our overhead water tank leak onto the terrace?
The continuous weight of water combined with thermal expansion causes hairline fractures in the tank floor and wall joints. Vibration from water filling also loosens pipe sleeve joints.
Can we use the water while waterproofing is being done?
The tank must be drained for 2 to 3 days to allow cleaning, application, and full curing of the food-grade coating.
Do you also waterproof the exterior of the overhead tank?
Yes! We apply an elastomeric solar-reflective coating to the exterior walls to reduce water heating during hot summer months.
How do you seal the outlet and overflow pipes?
We pack pipe penetrations with non-shrink polymer mortar and apply an elastomeric food-grade polyurethane collar around each pipe.
