Questions & Answers
Frequently Asked Questions
8 Questions
Polyurethane (PU) injection grouting involves drilling small holes into the underside of a leaking concrete ceiling and inserting mechanical packers. Hydrophobic PU chemical resin is then pumped in under high pressure. When it meets moisture, it expands up to 20 times its volume into a dense, flexible rubber seal that blocks all water pathways.
Not necessarily. If the structural concrete slab is sound and the leak is primarily due to compromised tile grout lines, our no-hacking chemical waterproofing treatment can solve it. We apply a deep-penetrating water-repellent compound that infuses into the pores of the floor substrate to create a subsurface hydrophobic shield.
Depending on the repair methodology used, professional residential waterproofing warranties generally range from 1 year to 5 years. For instance, targeted PU injection grouting typically comes with a 1 to 2-year warranty, while full-hacking bathroom or roof membrane replacements often include up to a 5-year coverage period.
Under HDB's co-management policy, responsibility for an inter-floor leak is shared equally between the upper-floor and lower-floor flat owners. Both neighbors must cooperatively arrange for inspection and split the repair costs, unless the leak originates from an external wall or public pipe infrastructure.
Active water leaks typically display expanding watermarks, blistered paint, or visible dripping, and the concrete stays damp to the touch. High humidity usually causes surface-level dark mold spots without structural bubbling. We use precise electronic moisture meters to verify subsurface dampness levels.
Waterproofing failures are mostly caused by house structural settling, micro-vibrations, or natural material aging. As a building settles, micro-cracks form in the concrete floor slab. If the old chemical or screed membrane lacks sufficient elastomeric flexibility, it ruptures along those stress lines, letting water pass.
Outdoor membrane applications require a completely dry substrate to bond properly. If it rains onto exposed concrete, moisture gets trapped inside the pores, leading to blistering later. While we schedule outdoor roof projects around fair weather windows, internal fixes like PU grouting can be safely executed anytime.
A water ponding test involves blocking floor drainage outlets in a newly waterproofed area, filling the floor with roughly 25-50mm of water, and leaving it submerged for 24 to 48 hours. This structural test verifies that the newly applied membrane is completely free of pinholes or weak seams before final tiling begins.
