Indoor infiltration
Stains, mould, damaged ceilings
Roofs and terraces
Leak and infiltration detection on flat roofs, terraces, pitched roofs and waterproofing.
Common problems
Waterproofing defects
Membranes, coverings, joints and upstands
Terraces and balconies
Infiltration at slabs, planters and drains
Critical details
Outlets, rooflights, parapets, penetrations
Rooftop equipment
Solar panels, pipework and fixings
Our technologies
On a roof or terrace, the goal is to find the waterproofing defect before redoing it: we reproduce the infiltration in a controlled way.
Fluorescein and UV lamp
Tracer dye links the stain inside to the entry point on the roof.
Flood and targeted spray tests
Flooding or spraying area by area to reproduce the leak.
Smoke testing
Smoke under the membrane escapes through lifts and punctures.
Electrical membrane testing
Electrical scan of the membrane to find punctures.
Infrared thermography
Shows wet areas trapped under the waterproofing.
Moisture meter
Measures moisture in insulation and substrates.
Tracer gas
Reveals waterproofing defects under membranes or tiles.
Endoscopic camera
Checks upstands, parapets and hard-to-reach details.
Our interventions
A few real cases handled by our teams, taken from our intervention reports.
TerraceApartment with terrace
Plaster was peeling at the bottom of a living-room wall. With the water pipes found watertight, targeted spraying of the terrace revealed several waterproofing defects causing the infiltration.
RoofWarehouse at the foot of a building
Water was dripping from the warehouse ceiling during heavy rain. Targeted spraying of the roof revealed defects in the waterproofing upstands and a cracked skylight.
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.
RoofApartment under the roof
Damp and flaking paint on the ceiling of a 4th-floor apartment. Targeted spraying revealed sealing defects along the flashing and around two roof windows.
RoofCondominium
Water ran down an office ceiling every time it rained heavily. A roof inspection and spraying located the leak at a cracked tile and the verge masonry.
