Transforming the approach to Riser Management
By taking a holistic approach during early stages of design, incorporating a versatile and lightweight riser unit overcomes the multiple challenges faced by contractors throughout the construction process. This is the beginning of a journey that reduces risk, minimises waste and drives efficient construction processes.

Welcome to AlphaRiser
The integrated and versatile approach to Riser Management.
Eliminate the creation of a floor void
AlphaRiser systems are incorporated into the construction process from the beginning of the programme. As the core and frame is assembled.
Eliminate temporary concrete shuttering
AlphaRiser is built into the structure. The unique outer frame of the unit integrates into the floor slab and provides the shuttering for the slab edge.
Eliminate temporary edge protection
The finished surface is safe to walk on and eliminates the need for temporary protection throughout the remainder of the build programme.
Simple adjustable system to position and fix MEP services
Once MEP works commence, penetrations can be marked up and cut out through the lightweight GRP grating to allow services to pass through.
Who we work with
People who work to improve the tomorrow
Comtec work with forward-thinking designers, project managers and construction professionals who are involved with creating the service riser voids in multi-level buildings and who want to streamline the programme management, reduce risk and eliminate the wasted time and processes in the typical approach to riser floors.
