Terrace Waterproofing
Seamless elastomeric PU & acrylic coatings resistant to thermal expansion & ponding
Sub-surface Degradation & Ingress Risks
Tropical heat causes concrete slabs to expand and contract dramatically, tearing rigid coatings and causing severe ceiling leaks and damp patches in top-floor living areas.
Engineered Multi-Barrier Protection
We provide high-elongation (>400%) seamless polyurethane and reinforced polymer matrix systems that bridge dynamic thermal cracks while reflecting UV solar radiation to lower ambient indoor temperatures.
Specified Chemical Formulations
- Vchemics Liquid PU Elastomeric Membrane
- Fiberglass Mesh Reinforcement Layer
- UV-Resistant Aliphatic Topcoat
- Polymer Screed Slope Mortar
Engineered Application Scope
- Exposed residential flat roofs
- Commercial podiums and sky decks
- Green roofs & landscaped terraces
- Industrial metal / concrete composite roofs
Standard Operating Protocol
4-Stage Application Methodology
Slope & Coving Correction
Creating minimum 1:100 drainage gradients and 75mm radius corner fillets.
Primer Impregnation
Penetrative moisture-tolerant epoxy/acrylic primer layer.
Reinforced Membrane Matrix
Multi-coat elastomeric PU embedded with 45 GSM fiberglass mesh.
Water Ponding Test
72-hour continuous water head retention inspection before handover.
Site Execution Gallery
How We Worked
Step-by-step photographic breakdown of real-world site execution, obstacles managed, and progressive structural sealing.
Worker grinding a concrete terrace slab surface before waterproofing
Surface Preparation
Terrace slab mechanically ground to remove laitance and surface contaminants, creating a sound, receptive substrate ahead of waterproofing application.
Fabric-reinforced polyurethane waterproofing membrane laid across a terrace slab
Base Membrane & Fabric Reinforcement
Nitoproof 68RFI polyurethane waterproofing system applied with fabric reinforcement bedded across the full terrace area, forming a seamless, crack-bridging base membrane.
Workers placing protective screed over a waterproofed terrace using a concrete pump
Protective Screed Application
Protective screed placed over the cured membrane via concrete pump, shielding the waterproofing layer and preparing a stable base for the finish coats.
Worker rolling a textured protective topcoat onto a terrace surface
Textured Protective Topcoat
A reflective textured topcoat rolled onto the cured screed, adding surface durability and helping reduce heat absorption on the finished terrace.
Worker applying green pigmented waterproof topcoat to a terrace and parapet wall
Final Pigmented Waterproof Topcoat
Final pigmented waterproof topcoat hand-rolled onto the terrace and parapet upstands, completing a fully sealed, UV-resistant finish.
