Waterproofing Contractor in Singapore

It comes down to the substrate, whether it moves, whether the surface is exposed to UV or covered, whether it will be walked on, and how long water sits on it after rain. Torch-on membrane suits large open flat roofs; liquid-applied suits complex shapes with many penetrations. If a quotation just says "waterproofing" with a price and no named system, you do not yet have enough information to compare it against anything.

Membrane failure is the leading cause of recurring repair work in Singapore buildings, and it almost always starts at the details rather than the middle of a flat surface, laps, upstands, drain outlets and pipe penetrations. Exposed membrane left without its protective covering also degrades far faster under Singapore UV than the datasheet suggests. We look at where yours failed before quoting to redo it.

Usually, yes. A membrane has to sit on sound substrate and be dressed properly into upstands and around floor traps, which in a wet area means lifting the finishes. Where a topical or injection solution is genuinely appropriate we will say so, but we will not pretend a surface coat fixes a failed membrane underneath it.

Typically three to seven days end to end, driven by curing time between coats and the ponding test rather than by how long the application takes. If you only have one bathroom, tell us at the quotation stage and we will sequence the work around that.

That is precisely what the survey is for. Moisture meter readings and thermal imaging trace where the water is actually travelling before anything is opened up, so any breaking out is targeted rather than exploratory.

Inter-floor leakage is common in Singapore and it is a shared problem rather than solely yours. We document what we find in writing, so you have something factual to put in front of the neighbour, the MCST or HDB. We cannot enter or carry out work in another unit unless that owner engages us directly.
