Double Layer 450gsm GRP Fibreglass Roofing Kits — Built for Balconies & Walkways

Available from 5m² up to 50m², our Double Layer Balcony & Walkway Fibreglass Roofing Kits are engineered for surfaces that demand the highest level of strength, waterproofing, and durability. Whether you're waterproofing a balcony, terrace, flat roof walkway, or any area subject to regular foot traffic, this is the kit built for the job.

We've been supplying and installing GRP fibreglass systems for many years — we know what works, and this double layer system is our go-to recommendation for balcony and walkway applications where performance cannot be compromised.

Why Double Layer?

A double layer application using 450gsm fibreglass matting provides significantly enhanced tensile strength and waterproofing integrity compared to a single layer. It's the professional standard for balconies, walkways, and any surface exposed to regular movement, thermal cycling, and the elements.

• ✅ Superior strength and crack resistance
• ✅ Excellent waterproofing — no joints, no seams, no leaks
• ✅ Handles foot traffic and structural movement with ease
• ✅ Long-lasting protection — 50+ year lifespan when correctly applied
