Ambar Kelly Ltd

RiserSafe provides top-tier, custom-engineered, non-combustible (BS EN 13501-1 Euroclass A1) modular riser flooring solutions for constructing riser shafts in multi-storey buildings. Designed for fast-track installation and BIM integration, these durable units function as permanent formwork—robust steel boxes with integrated floor plates that secure structural riser openings, prevent falls from height, and limit smoke and fire spread during and after construction.

Each RiserSafe unit is fully tailored to support the vertical routing of mechanical, electrical, and plumbing (MEP) services, ensuring safe maintenance access and optimised coordination between architectural, structural, and services layouts. Aligned floor openings form continuous riser shafts, which RiserSafe secures by providing load-bearing fixing points for passive fire protection systems and enabling horizontal fire compartmentation using fire-resistant compounds.
