Nextech Waterproofing delivers wall leakage repair Singapore landed homeowners trust, treating water entering through cracked render, a deteriorated waterproofing membrane, or porous brickwork. We trace the entry point with thermal imaging and moisture mapping, then apply PU crack injection, non-hacking sealant, or full hacking waterproofing, backed by a 1 to 10-year warranty.
Landed home walls leak mainly from wind-driven monsoon rain forcing water through hairline cracks, failed waterproofing at boundary and party walls, planter boxes draining moisture sideways into brickwork, and capillary rise from wet soil at the foundation line. Homes over 15 to 20 years old are most exposed because the original waterproofing membrane has degraded.
We don’t patch visible stains. We trace the entry point using infrared thermal imaging to map moisture behind plaster, a calibrated moisture meter to measure saturation depth, and a dye or flood test on suspect joints where needed. You receive a photo report before any repair begins.
Non-hacking wall leakage repair injects polyurethane (PU) resin or applies a penetrating sealant directly onto the existing wall surface, faster, less disruptive, and backed by a 1-year warranty. Hacking repair strips plaster back to brick or RC, replaces the waterproofing membrane, and re-renders, a longer-lasting fix backed by a 10-year warranty. Non-Hacking (1-Year Warranty)
Hacking / Full Re-Waterproofing (10-Year Warranty)
Wall leakage repair in Singapore costs from $80–$150 per linear metre for PU crack injection, $300–$800 for an isolated damp patch, and $250–$450 per sq metre for full hacking and re-waterproofing. Boundary wall and planter box-related repairs typically range $800–$4,000 depending on wall length and access. Final pricing depends on site inspection.

Under Singapore’s Building Control regulations, landed homeowners are responsible for maintaining and waterproofing the external and boundary walls of their own property, even where a wall is shared with a neighbour. This is why wall leakage repair Singapore projects on boundary and party walls often need a joint site visit before work starts, so both households agree on the source of the seepage and the repair method.
Costs range from $80–$150 per linear metre for PU crack injection to $250–$450 per sq metre for full hacking and re-waterproofing. Boundary wall and planter box-related repairs usually cost $800–$4,000. The exact price depends on wall condition, access, and repair method, get a free site inspection for a fixed quote.
Non-hacking repair injects PU resin or applies sealant onto the existing wall surface without removing plaster, faster, less messy, 1-year warranty. Hacking repair removes plaster down to brick or RC, replaces the waterproofing membrane, and re-renders the wall, a more thorough fix with a 10-year warranty.
Thermal imaging and moisture mapping identify whether water is entering from an external crack, a concealed pipe, or lateral seepage from an adjoining boundary wall. We map the pattern during our free inspection before recommending a repair method.
Most Singapore home insurance policies cover sudden and accidental water damage but exclude gradual seepage caused by wear, poor maintenance, or ageing waterproofing. Check your policy’s water damage clause, and keep our inspection report as documentation if you file a claim.
Non-hacking crack injection or sealant application typically takes half a day to one full day. Hacking and full re-waterproofing of a wall or room takes 3 to 7 days depending on wall area and drying time between coats.
Yes. Non-hacking PU injection can be carried out in most weather since it seals from within the crack. Hacking works involving open plaster and membrane curing are best scheduled around forecasted dry spells for a clean finish, we plan around the weather at booking.
As the property owner, you’re responsible for waterproofing and maintaining your home’s external and boundary walls, including party walls shared with a neighbour. If the seepage originates from a neighbouring property’s negligence, a joint inspection can help establish the source before repair.
No. Wall leakage repair is localised to the affected wall, most landed homeowners stay in the house throughout, with dust control during hacking works. We section off the work area to keep the rest of the home usable.
