Filcor is a high-performance expanded polystyrene (EPS) structural fill and void former system designed for a wide range of construction applications, including groundworks, podium decks, landscaping, ramps, and in-situ concrete structures. Manufactured in multiple compressive strength grades, Filcor provides a lightweight yet durable alternative to traditional fill materials such as soil, hardcore, and aggregate.

Engineered to reduce structural load while improving construction efficiency, Filcor EPS can be cut or profiled to suit project-specific requirements, making it ideal for complex shapes, falls, and engineered voids. Its closed-cell structure offers additional thermal benefits and long-term dimensional stability in demanding environments.

Available in a wide range of grades to meet different loading requirements, Filcor is widely used across UK construction projects where lightweight fill, structural accuracy, and cost efficiency are essential.
