Surface Preparation
- Thorough cleaning to remove dust, oil, and old coatings.
- Crack and joint repair for a smooth base.
- Leveling and preparation of all surfaces before application.
Waterproofing Application
- Use of advanced waterproofing systems such as liquid-applied membranes, sheet membranes, or bituminous coatings.
- Priming the surface for improved bonding and adhesion.

-
We use BCA-approved and HDB-compliant waterproofing methods trusted across Singapore.
Joint Sealing
- Sealing of expansion joints, construction joints, and pipe penetrations using industrial-grade sealants or waterproof tapes.
- Ensuring a watertight barrier in areas prone to leakage or movement.
- Effective sealing prevents water ingress and protects structural integrity.
Drainage and Water Management
- Installation or correction of slope gradients to facilitate proper water runoff.
- Repair or integration of new drainage outlets, scuppers, and gutter systems.
Especially important for flat roofs and terraces to prevent standing water.
Testing and Quality Assurance
- Flood testing or leak detection to verify waterproofing integrity.
- On-site inspection and rectification of weak points.
- We don’t just apply waterproofing—we test and prove it works.
Final Finishes and Protection
- Protective finishes like tiles, screeds, or UV-resistant coatings to improve durability and aesthetics.
- Final handover inspection to ensure long-lasting waterproofing performance.
We ensure the treated area is both protected and presentable.
