Basin leaks
Water level drop with no obvious cause
Pools and aquatic centres
Precise leak location on private pools, hotels, residences and special basins.
Common problems
Lining leaks
Liners, tiles, joints and fittings
Equipment leaks
Skimmers, drains, pipes and plant rooms
Infinity pools
Waterproofing defects and circulation losses
Pipework and plant rooms
Leaks on pipes, fittings and equipment
Our technologies
A pool combines the basin, fittings and buried pipes: each area has its own detection method.
Scuba diving
Inspection of skimmers, jets, main drain and lights, without draining.
Fluorescein and UV lamp
Dye placed next to fittings to see where water is drawn out.
Pressure testing
Each pipe (suction, return, main drain) is tested one by one.
Tracer gas
Locates leaks on pipes buried under the deck and slab.
Electro-acoustic listening
Listening to pipes and basin to pinpoint the leak.
Pipe video inspection
Internal inspection of the pool pipework.
Electrical membrane testing
Detects punctures in the liner or reinforced membrane.
Infrared thermography
Spots damp areas around the basin and in the plant room.
Our interventions
A few real cases handled by our teams, taken from our intervention reports.
PoolPrivate pool
Water was seeping out between the tiles and a coping stone whenever the pool was running. Pressure testing and tracer gas located an embedded leak on the return line, inside the pool wall.
PoolVilla with pool
The water level dropped every day and water was running at the foot of a wall. Each line was tested in turn, then a camera inspection revealed a break on the return line, under the slab.
PoolVilla with pool
The water level was dropping with no visible leak. With every line watertight, fluorescein dye revealed sealing defects around a return inlet and the main drain.
Aquatic centreLarge marine-park pool
The main-drain lines and their collector were tested with tracer gas, manhole by manhole. Three of the four lines were cleared, and the report sets out the tests still needed on the large-diameter sections.
PoolHouse with pool
The pool's return line had already leaked twice before. Tracer gas located a new buried leak in the garden, opposite the ladder, without breaking the ground.
PoolResidential complex pool
The level dropped, then stabilised between the skimmers and the lights. After ruling out any leak on the technical lines, a vacuum-bell test and fluorescein located the defect at the cable gland of a pool light.
PoolVilla with pool
The level dropped every day to about 40 cm below the waterline. With the lines watertight, fluorescein revealed four defects: a skimmer seal and three cracks in the walls.
