Belzone Effects Emergency Repairs To Leaking Swimming Pool



Local Authorities & Municipalities (LOMU)



Floor Problem Areas (FPA)


Customer Location:

Public swimming pool, British Columbia, Canada


Application Date:

August 2011


Application Situation:

Public swimming pool in emergency shutdown due to chronic water leakage.



Vibration from the use of a “jackhammer “ by a contractor in the pool basin to expose leaking pipes had caused cracks to develop in the concrete grout forming the edges of this pool’s unique expansion joint system. Dye testing located 12 separate leaks.



Belzona® 4111 (Magma Quartz)

Belzona® 2211 (MP Hi-Build Elastomer)





Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflets FPA-5 & FPA-6. Cracked grout was  removed and joint edges rebuilt with Belzona®  4111, followed by repair with Belzona MP Elastomer  of the expansion joints in affected areas.


Belzona Facts:

The emergency Belzona repairs were completed over a period of two days and the pool was re-opened to the public one week after the Belzona repairs had been completed. Leakage was found to be even lower than before the initial problem had arisen.
