How is Fibreglass Installed?

GRP fibreglass, also known as glass reinforced plastic, is a popular choice for relining concrete ponds due to its durability and versatility. In this blog post, we’ll explore the steps involved in installing GRP fibreglass to a concrete pond.

Step 1: Preparation

The first step in relining a concrete pond with GRP fibreglass is to thoroughly clean and prepare the surface. The concrete should be free of any dirt, debris, or loose particles that may interfere with the adhesion of the fibreglass liner. Additionally, any cracks or gaps in the concrete should be filled in and smoothed over.

Step 2: Sizing and Cutting the Fibreglass Liner

Once the concrete is prepared, the next step is to size and cut the GRP fibreglass liner. The liner should be cut to the correct size and shape to fit the dimensions of the pond. It’s important to leave an additional 6-8 inches of liner on each side to ensure that it can be properly installed and trimmed.

Step 3: Applying the Resin

Before the GRP fibreglass liner can be installed, a resin must be applied to the concrete surface. The resin should be applied evenly and generously to ensure a strong bond between the fibreglass liner and the concrete. Once the resin is applied, the GRP fibreglass liner can be carefully placed onto the surface of the concrete.

Step 4: Smoothing and Trimming

Once the GRP fibreglass liner is in place, it’s important to smooth out any air pockets and ensure that the liner is properly adhered to the concrete. Any excess liner should be trimmed and removed to create a clean and precise finish.

Step 5: Curing

After installation, the GRP fibreglass liner must be allowed to cure for a period of time before the pond can be filled with water. The curing time can vary depending on the temperature and humidity of the installation site, so it’s important to follow the manufacturer’s recommendations.

Overall, the installation of GRP fibreglass to a concrete pond requires careful preparation and attention to detail to ensure a successful and long-lasting result. By following these steps, pond owners can enjoy the benefits of a durable and attractive pond that will provide years of enjoyment.
