Ceiling leak repair and PU injection grouting Singapore — stop water seepage from above without hacking. Specialist polyurethane crack injection for concrete slabs and structural cracks.
Ceiling leaks are usually caused by water seeping through cracks in the concrete slab above. Best Waterproofing SG specialises in PU injection grouting — a highly effective non-invasive method to stop active ceiling leaks permanently.
Polyurethane resin is injected under low pressure into cracks — it expands to fill voids completely and cures to form a permanent waterproof seal.
PU injection works from below — no need to hack the floor above. Minimal disruption, no mess, and works even on active leaks.
Our PU grouting system is highly effective even on actively dripping leaks. Works in wet conditions where other methods fail.
Suitable for structural cracks in reinforced concrete slabs, beams and walls — restores structural integrity while stopping water ingress.
Used extensively in commercial buildings, HDB blocks, condominiums and car parks. Effective for both small hairline cracks and larger structural voids.
All ceiling leak and PU injection works are backed by a 2-year written warranty for your peace of mind.
