Hy-Rib Permanent Formwork

Reduced risk of Hand & Arm vibration injury (white finger): product featured in HSE document - Vibration Solutions Ref HS (G) 170

When Hy-Rib is used as vertical formwork, the resulting formwork pressure is significantly less than that developed with traditional forming materials, reducing the overall support requirement.

Expamet Hy-Rib joint surfaces require minimal preparation prior to the next pour, with the exception of the rebar cover zones. It minimises the labour, mess and disposal requirements associated with scabbling, chemical retarders and jet washing.

A correctly formed Hy-Rib joint outperforms traditionally prepared joints in shear and bond.

Hy-Rib reduces the risk of trapped air and voids within the concrete.

The range of narrower sheet widths improves site productivity and minimises wastage.

Hy-Rib is a proven construction product with comprehensive technical data, manufactured by an established UK company.
