Waterproofing Systems & Solutions
Long-term structural protection against water ingress for every part of your building envelope in Singapore’s demanding tropical climate.
Service Overview
Water intrusion is the single most damaging threat to any building in Singapore’s tropical climate. Our waterproofing division designs and installs complete membrane systems — from liquid-applied polyurethane and cementitious coatings to torch-on membranes and nano-sealing treatments — matched precisely to your substrate, exposure and usage conditions. Every installation is preceded by a thorough moisture diagnosis and completed with flood testing where applicable.
What is a Waterproofing Membrane?
Waterproofing membranes are specialized layers of watertight material deployed to prevent water from penetrating structural slabs, walls, and foundations. They fall primarily into two comprehensive categories:
Sheet-Based Membranes
Supplied in rolls that unroll onto prepared flat or curved surfaces. Bituminous sheets are among the most robust roll-fed solutions for industrial and residential roofs.
Liquid-Applied Membranes
Fluid-applied polymers or acrylics brushed, rolled, or sprayed onto substrates. They cure into a monolithic, seamless blanket with no joints or weld laps.
Available Waterproofing Membrane Systems
1. Torch-On Membrane (APP & SBS)
High Exposure RoofsEngineered from a heavy-duty mix of polymers and bitumen, torch-on membranes are thermally bonded to substrates using specialized gas torches. They provide exceptional standing-water resistance on flat roofs, balconies, and concrete gutters.
2. Liquid Applied Acrylic & Polyurethane Membrane
Seamless FinishPolymer-based, fiber-reinforced liquid formulations that cure into a rubbery, seamless waterproofing jacket. Excellent crack-bridging capability up to 2 mm, perfect for complex roof geometry, wet areas, and retaining walls.
3. EPDM Rubber Membrane
UV & Weather ProofEthylene Propylene Diene Monomer synthetic rubber sheets offering outstanding elasticity and exceptional resistance to direct solar UV radiation, ozone, and weathering extremes.
4. Self-Adhesive Modified Bituminous Membrane
Cold ApplicationCrafted from asphalt, polymers, and mineral stabilizers reinforced with polyester or fibreglass. Applied cold by peeling away release film, eliminating open flames in sensitive or restricted environments.
Key Benefits
- Stops leaks at the source, not just masking symptoms
- Systems precisely matched to substrate movement and UV exposure
- Extends structural lifespan and prevents expensive concrete remediation
- Comprehensive workmanship warranty on all completed systems
- Minimal disruption to occupants and daily operations during installation

Frequently Asked Questions – Waterproofing in Singapore
1. What waterproofing services does Yong Feng Buildtech provide in Singapore?
Yong Feng Buildtech provides waterproofing solutions for roofs, balconies, bathrooms, kitchens, wet areas, external walls, basements, retaining walls, lift pits, water tanks and swimming pools in Singapore.
2. How do I know where a water leak is coming from?
Our team carries out an on-site inspection and moisture assessment to identify the likely source of water ingress before recommending an appropriate rectification or waterproofing method.
3. What types of waterproofing systems do you use?
Depending on the substrate, exposure and site condition, waterproofing solutions may include torch-on membrane systems, liquid-applied acrylic or polyurethane membranes, EPDM rubber membranes and other suitable systems.
4. Can you repair waterproofing without replacing the entire system?
In some cases, localized waterproofing or leakage rectification may be possible. The appropriate method depends on the source of leakage, condition of the existing waterproofing system and accessibility of the affected area.
5. Do you provide waterproofing for landed houses, commercial and industrial properties?
Yes. Yong Feng Buildtech provides waterproofing and water leakage rectification solutions for residential, commercial and industrial properties in Singapore.
6. Do you provide site inspections?
Yes. Customers can contact Yong Feng Buildtech to arrange a site inspection so the affected area can be assessed before an appropriate solution is proposed.
