    Tunnels & Basements

    Construction projects in tunnels or basements are vital for infrastructure expansion. Engineers and workers face unique challenges such as limited space and ventilation, making safety and innovation paramount. Composites are known for their high strength-to-weight ratio, making them ideal for structural components in these environments, as they reduce the load on foundations or substructures.

    We offer phenolic flooring as well as a range of Dura Slab heavy-duty GRP trench covers specially designed for use in basements and below-ground structures with specific fire performance requirements. These trench covers meet the 60-minute burn time standard mandated for buildings exceeding four storeys in height. We would be pleased to furnish you with copies of the fire testing certification for specific products, and you can also find further guidance in our fire safety technical briefing document.

    Please be advised that obtaining building regulation approval is a mandatory step for constructing, adapting, or extending all basements. Approved Document B outlines the building regulations for fire safety matters in England within and around buildings, while separate guidance is available for Scotland.

    GRP Phenolic Grating

    Our GRP phenolic flooring products are ideal for installation in shafts and tunnels housing vital ventilation and emergency exit facilities. They are available in both open mesh and solid formats, sporting a distinctive russet red colour for easy on-site identification. These floors are expertly engineered to withstand prolonged exposure to fire without compromising their structural integrity. However, it’s important to be aware that phenolic products may have extended lead times.
