* Overhauls: Comprehensive roof truss replacements and complete re-roofing projects.
* Industrial & Commercial: Heavy-duty cladding replacement and commercial rooftop maintenance.

**Waterproofing:**
* Torch-On Bitumen Membrane: High-durability (15-20 years lifespan), open-flame application, ideal for large flat concrete roofs and HDB rooftops.
* Liquid Polyurethane (PU) Coating: 100% seamless, highly flexible (500% elongation), perfect for balconies, planter boxes, and complex geometric structures.
* Clear Penetrating Waterproofing: Non-destructive chemical flood treatment applied over existing tiles in bathrooms or balconies without hacking.

**Leak Repair & Diagnostics:**
* Advanced Diagnostics: Non-invasive inspection using thermal imaging cameras and digital moisture meters to locate hidden leaks.
* PU Injection Grouting: High-pressure injection of polyurethane resin to seal concrete slab cracks from the lower unit. 90% of inter-floor HDB repairs use this clean, fast, and no-hacking solution.

**Structural Works:**
* Spalling Concrete Repair: Hacking away degraded concrete, anti-rust rebar treatment, mortar patching, and anti-carbonation coatings.
* Roof Timber & Truss Reinforcement: Reinforcing rotted wood frameworks to restore load-bearing capacity.

**4. Singapore HDB Ceiling & Roof Leak Guidelines**

For users inquiring about who is responsible for HDB leaks and what the costs are, reference this standard playbook:

**Responsibility Framework:**
* Top-Floor Main Roof Leaks: If the leak originates from the building's main concrete roof or external facade walls, it is classified as common property. The respective Town Council is 100% responsible for repairs; the flat owner pays nothing.
* Inter-Floor Leaks (Toilet, Bathroom, Kitchen): If water leaks from the unit above, HDB regulations stipulate a 50-50 cost split between the upper and lower unit owners, as the floor slab is a shared boundary.
* Goodwill Repair Assistance (GRA) Scheme: Flat owners can apply to HDB for the GRA scheme. HDB co-pays 50% of the basic repair cost, and the remaining 50% is split equally (25% each) between the upper and lower neighbors. However, GRA only covers basic methods and can take months to process.

**Repair Methods & Costs (2026 Rates):**
* PU Injection Grouting (No-Hacking): Cost SGD $300 to $800. Time 2 to 4 hours. Process done entirely from the lower unit's ceiling. Clean, quiet, and doesn't disrupt the upper neighbor's tiles.
* Clear Penetrating Waterproofing (Non-Hacking): Cost SGD $500 to $1,200. Process flooded over the upper unit's bathroom tiles to seal porous grout lines.
* Full Hacking & Re-Waterproofing: Cost SGD $2,500 to $6,000. Time 3 to 5 days. Process hacking tiles, laying new membrane, 24/48-hour ponding test, re-tiling. Highly disruptive, but the ultimate permanent solution.
