The SlotBlock Barrier is a patent pending, site safety barrier exclusively designed and manufactured in the UK. The SlotBlock Barrier is the only water filled barrier designed to hold standard 3.5 m ‘Heras Style’ fencing panels to increase site safety, virtually eliminate trip hazards, and give added stability.
Independently tested by MIRA, the SlotBlock Barrier enables standard fence panels to withstand winds up to a maximum speed of 57 mph. This prevents standard fence panels from blowing over and saves valuable time and money with constant re-erection and damage to site fencing.
The SlotBlock Barrier is manufactured in standard red and white colours providing clear demarcation of site entrances and roadways as well as adding additional corporate identity.
When using the Slotblock Barrier contractors dramatically reduce the working footprint on site by an average of 500 mm against a standard fence block.
The SlotBlock Barrier can also be used in conjunction with our other Safety Barrier system to provide a comparable half size hoarding system
