GRP linings have long been a trusted choice for koi ponds, reservoirs, and industrial applications, and now, the same technology can be applied to swimming pools. Unlike traditional pool coatings, GRP creates a fully sealed, non-porous surface that is chemical-resistant, waterproof, and highly durable.

With a GRP lining, you benefit from:

✔ A Seamless, Leak-Proof Finish – No joints or weak points where water can seep through.
✔ Exceptional Durability – Designed to withstand pool chemicals, heat, and everyday wear.
✔ A Smooth, Low-Maintenance Surface – Reduces algae growth and makes cleaning easier.
✔ Customisable Colours & Finishes – Achieve a sleek, modern look tailored to your pool design.

We take pride in delivering high-quality GRP linings with a meticulous, step-by-step process to ensure a flawless result:

1️⃣ Preparation – We start by fully cleaning and preparing the pool surface, removing any old coatings or debris.
2️⃣ Surface Priming – A high-quality primer is applied to enhance adhesion and create a perfect bonding layer.
3️⃣ GRP Application – Layers of resin and fibreglass matting are applied, forming a tough, reinforced surface.
4️⃣ Chemical-Resistant Topcoat – A final protective gel coat is added, ensuring resistance to chlorine and pool chemicals while providing a smooth, polished finish.
5️⃣ Final Curing & Inspection – Once cured, we conduct a thorough quality check to ensure a perfect, watertight seal.
