SwimmingPoolSurveys - Repair and Refurbishment

Injecting water reactive polyurethane into a hairline crack

Problems Solved

	Significant leak in an internal pool supplied with metered water. *Our underwater survey and dye test showed movement around one underwater light pod caused by leakage from the electrical connections behind.*
	A sticky sealant caused discomfort to school pool users. *Our investigations found excessive use of dilute phosphoric acid by the caretaker to remove surface salts in the pool.*
	A client was very unhappy with the quality of refurbishment work to a large public lido carried out by a main contractor. There was poor finishing to the new concrete floor; slight leaks and slumping even though watertight concrete had been supplied. Also the existing old wall render had been patch repaired and was not waterproof, and the water stops between the new and old work were incorrectly installed.
	A large panel pool had been installed and over five years the liner had split, pipe connections cracked, the panels became distorted, and the pool unusable. *The pool had been built on a sloping clay garden without proper sub-soil drainage and the panels had not been back-filled with the correct shingle.*
	A preformed glass fibre pool and spa bath was cracked, leaking below the waterline, and tilting so much that the circulating water system no longer worked. The pool had been placed on top of site debris and back-filled with concrete instead of pea shingle, which should have been added when the pool was first filled with water. We advised complete replacement.
	An English client was quoted 10,000 Euros for a liner to solve the problem of a leaking outdoor pool in Spain. *We recommended the use of an underwater sealant to repair the crack and restore missing mosaics in the tile band. Material cost £80*
