Stop leaks underwater while Repairs are completed

 NCH, provides underwater cost effective repair solution for an cooling tower application to a renowned Hospital and saves them costs!

India, February 2019

Deenanath Mangeshkar Hospital & Research Center is a charitable, multi-specialty hospital located in the heart of Pune, India. Founded in 2001, today it is one of the largest hospital in Pune, with 800 beds. Deenanath Mangeshkar Hospital offers state-of-the-art diagnostic, therapeutic and intensive care facilities in a one-stop medical center.

The Challenge

During the project execution stage Cooling Tower 600TR sump was not isolated properly with FRP sheet which was to act as the partition. Due to which the engineering team was unable to do the routine cleaning or emergency leakage breakdown activity as the water was getting collected in abundance from the 6 cooling towers placed in a row.

Hospital works at the schedule of 24x7x365 days therefore shutting down cooling tower system was not possible for any kind of repair work. This would have been highly inconvenient for the patients as well would have incurred loss for the hospital.


AQUA STICK - Underwater Repair Compound - Used to Stop Leaks While Repairs Are Completed.

Aqua stick is a two-part hand-kneadable polymer compound in a single stick. its unique formulation changes the product from aqua marine color to white upon mixing. It is designed for application to wet or dry surfaces.

It is unaffected by moisture and many chemicals and reduces downtime and the requirement for replacement parts. The putty consistency provides a “no mess” gap filling application without the use of tools.


After applying Aqua Stick in Cooling tower sump partition, engineering team was able to arrest water overflowing from one sump to another.

Customer immediately drained water from 2 sumps and next day applied FRP coating for permanent isolation. (For partition in Sump area)

Now they are able to do the regular cleaning job of each sump by isolating and draining individual cooling tower sumps.

Clients Feedback

We thank you for such a wonderful invention & implementation done by NCH. Till date we had never heard about under water repair compound. You approached us, understood our problem and suggested to implement repair work online & carried out service to complete the successful task.

If Aqua stick was not applied in cooling tower sump partition and in case of emergency shutdown due to leakage in any of cooling tower sump plant would have to close down its operations and incur huge loss.  

This specialty hospital may have to be closed which has 15 OT setup and ICU Floors patients had to be discharged to other hospitals or elsewhere. This would have made caused great inconvenience to our in-house patients especially admitted into ICU. Thank you once again for this solution.
