Terrace & Roof Waterproofing in Hyderabad
A leaking terrace is usually the first sign of a building’s waterproofing failing, and if left untreated it damages the RCC slab, causes seepage into the ceiling below, and leads to far more expensive structural repairs. Mythri’s terrace waterproofing system is designed to handle direct sun exposure, monsoon rainfall, and daily thermal expansion — the three biggest stress factors on a Hyderabad rooftop.

Common Causes We See in Hyderabad
- Hairline cracks in the RCC slab widening over time due to thermal expansion and contraction
- Ponding water from poor drainage slope, which keeps the surface saturated for hours after rain
- Old or degraded waterproofing coating that has lost its elasticity and flexibility
- Improperly sealed pipe penetrations, parapet joints, and expansion joints
- UV degradation of exposed membranes that were never top-coated
Our Process
- 1 Surface preparation — cleaning, crack repair, and leveling
- 2 Primer application for better adhesion
- 3 Waterproofing membrane or coating application (2–3 coats)
- 4 UV-protective top coat for long-term durability
- 5 Drainage slope correction where needed
Frequently Asked Questions
How long does terrace waterproofing last?
A properly applied terrace waterproofing system with a UV-protective top coat typically lasts 7–10 years before it needs a recoat, depending on sun exposure and foot traffic.
Can waterproofing be done during the monsoon?
We recommend waterproofing work on dry days with at least 24–48 hours of no rain forecast, since the coating needs time to cure before it can handle water contact. We schedule around the weather when you book.
Do you fix drainage/ponding issues too?
Yes — if ponding is caused by an incorrect slope, we correct the slope with screed before applying the waterproofing layer, since coating alone won’t fix a drainage problem.
Is the terrace usable immediately after treatment?
The surface needs a curing period (typically 2–3 days depending on the material used) before it should take regular foot traffic or water tank refilling.
