Waterproofing is one of the most essential parts of property maintenance in Singapore. With our humid climate, frequent rain, and aging building structures, water seepage and leakage problems are increasingly common across HDB flats, condominiums, landed homes, offices, shops, and commercial buildings. Whether it’s bathroom leakage, ceiling stains, roof seepage, or wall dampness, untreated water issues can lead to serious damage, expensive repairs, and health problems caused by mold and bacteria.
That is why choosing the right waterproofing contractor in Singapore is critical. At Unique Interior Private Limited, we specialize in providing high-quality waterproofing solutions that are built to last. Our team combines professional expertise, advanced materials, and proven waterproofing methods to deliver long-term protection and reliable results for all kinds of properties.
Why You Need a Professional Waterproofing Contractor in Singapore
Water seepage can be caused by several issues, including tile wear, cracks in concrete, faulty waterproofing membranes, pipe leaks, and structural movement. Without professional assessment, most property owners only treat the visible symptoms — not the underlying cause.
A trusted waterproofing contractor ensures:
- Accurate diagnosis of the leakage source
- Long-term protection, not temporary fixes
- Safe and proper waterproofing methods
- Compliance with HDB and Singapore building standards
- Warranty-backed waterproofing solutions
When waterproofing is done correctly, you minimize the risk of mold, structural deterioration, and repeated leaking.
Our Waterproofing Services in Singapore
As a full-service waterproofing contractor, we provide a comprehensive range of waterproofing solutions for residential, commercial, and industrial properties:
1. Toilet & Bathroom Waterproofing
Bathrooms are one of the most common areas for water leaks in Singapore. We provide waterproofing for:
- HDB bathrooms
- Condo bathrooms
- Landed property bathrooms
- Commercial toilets
Whether your tiles need hacking or you require a non-hacking waterproofing solution, we ensure your bathroom is sealed properly to prevent seepage to the lower unit.
2. Roof Waterproofing
Singapore’s heavy rainfall makes roofs vulnerable to seepage. We use:
- Torch-on membrane
- Liquid waterproofing
- Polyurethane coating
- Cementitious waterproofing
Our roof waterproofing protects your building from rainwater penetration and long-term structural damage.
3. Ceiling Leakage Repair
Ceiling leaks often come from upstairs units or roof areas. Our specialists locate the origin of the problem and apply the right waterproofing method to eliminate the leak permanently.
4. Balcony & Planter Box Waterproofing
Balconies and planter boxes are exposed to outdoor moisture. We apply flexible, weather-resistant waterproofing coatings to protect these areas and prevent seepage into interior walls or rooms.
5. Wall Seepage & Dampness Waterproofing
Wall dampness can come from external rainwater or internal plumbing issues. We use high-performance waterproof coatings and sealants designed for Singapore’s climate to stop seepage at the source.
6. PU Grouting & PU Injection Waterproofing
PU injection is one of the most effective methods for sealing cracks and stopping active leaks. It is ideal for:
- Structural cracks
- Basement seepage
- Pipe penetration points
- Lift pits
- Concrete walls
This method provides immediate sealing and long-term waterproofing.
7. Floor Waterproofing for Wet Areas
We provide waterproofing for kitchens, laundry areas, yards, and other wet spaces to prevent moisture from spreading to lower floors or adjacent walls.
8. Basement Waterproofing
Basements are prone to groundwater seepage. We provide heavy-duty waterproofing systems designed to withstand pressure and protect the foundation.
