Bespoke Void Protection System


Remove the hassle and cost of protecting voids and risers in the floor slabs with our specialist wHOLE.Protect™ System. wHOLE.Protect™ combines the benefits of anti-slip GRP moulded grating with bespoke, specially adapted edge shutter eliminating the need for scaffolding and handrail systems around internal voids.

By engaging with us early, ideally during the design phase, we can integrate void safety seamlessly into your build; leaving a safe, clear and uninterrupted working area for following trades. Our wHOLE.Protect™ System provides void protection and easy access routes through the decks for all trades and in our opinion, should be a standard in every deck installation. Watch our short 1.5 minute film on The 5 Benefits of wHOLE.Protect™.

We offer wHOLE.Protect™ as: Supply Only; a standalone Install Service and as part of our Full Metal Decking Service.
