Our technologies
In an apartment building, the challenge is to trace the problem back to the unit or network of origin without opening up several flats.
Electro-acoustic listening
Locates leaks on risers and embedded pipes.
Tracer gas
Finds leaks on pressurised networks in common areas and basements.
Pipe video inspection
Inspects drainage stacks and wastewater downpipes.
Infrared thermography
Shows the extent of water damage from one floor to the next.
Moisture meter
Maps moisture to trace back to the source.
Fluorescein and UV lamp
Identifies the flat or fixture causing water damage.
Endoscopic camera
Checks landing ducts and false ceilings without demolition.
Flood and targeted spray tests
Tests façades, terraces and windows for infiltration.
Our interventions
A few real cases handled by our teams, taken from our intervention reports.
Apartment buildingApartment above a shop
Water damage was affecting the restaurant below an apartment. Pressure testing, an endoscopic camera and targeted spraying revealed water seeping through the shower wall.
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.
RoofApartment building, top floor
The ceiling of a 5th-floor apartment was damaged. Spraying the façade cracks and the ridge caused immediate water ingress in the loft, confirming the source.
Apartment buildingResidential building
Damp was affecting the cellar corridor and a ground-floor ceiling. The investigation ruled out the drain stack and the roof, and pointed the search to the apartment above.
