What is GRP lining? Different types of GRP Lining.

GRP lining is the process of using Glass Reinforced Plastic (GRP), also known as Fiberglass, to line the interior of a structure or container. This lining is used to protect against corrosion and to provide a smooth, durable surface that is easy to clean and maintain.

There are several different types of GRP lining, including:

1. Hand Lay-Up GRP Lining: This is the most common type of GRP lining, and involves manually applying layers of GRP to the interior of a structure using brushes and rollers.
2. Spray-Up GRP Lining: This method involves spraying a mixture of resin and chopped fiberglass onto the surface to be lined using a spray gun. The layers build up quickly, making this method more efficient than hand lay-up.
3. Filament Winding GRP Lining: In this method, continuous strands of fiberglass are wound around a mandrel or template to create a custom liner that can be inserted into the structure to be lined.
4. Pre-fabricated GRP Lining: This involves constructing a GRP liner off-site and then inserting it into the structure to be lined. This method is often used for larger structures, such as tanks or pipelines.
5. Cured-in-Place GRP Lining: This method involves inserting a flexible GRP liner into the structure to be lined and then curing it in place using steam or hot water.

Each type of GRP lining has its advantages and disadvantages depending on the specific application, size and shape of the structure, and budget. It is important to consult with a professional to determine which type of GRP lining is best suited for a particular project.
