PSG Fastener has been providing anchoring solutions to all of the major precast tunnel systems across the country and throughout the world. Our Insulguard inserts provide the highest stray current protection available, and the strength needed for segmented precast tunnels.
Precast Segmented Tunnels producers tell us that they have reduced time and finances in maintenance by installing the Insulguard inserts in their tunnels.
Take a look at our Tunnel Case Studies for a quick look at some of the Tunnels that have used PSG Fastener products.
