“Our selection is not based on price alone…we also considered the safety & saving aspects”

“Our selection is not based on price alone, we also considered the safety & saving aspects. The Smart foundations allow quick replacement of items with no further effort required to the base, (providing a significant cost benefit in replacing the damaged item by re-using the existing footing) and reduces risk of injury to employees by reducing time spent on traffic islands exposed to traffic.” MAIN ROADS DEPT WESTERN AUSTRALIA

Smart Taper-lock 


Items are secured on Smart Sustainable Foundations using a self-locking taper ( that acts like a drill bit using friction to lock the item firmly in the ground socket)

Made from self-healing plastic, the Smart Taper-lock units are guaranteed to work effectively impact after impact, year after year (Lifetime Warranty!)

The Taper is attached to the item using self-drilling screws (supplied). The item is simply dropped into the ground socket, automatically locking in tight and can only be removed using tools provided. Smart Taper-lock is designed and manufactured in Australia.

  • Innovator of the Year
  • DOH&S Worksafe Award
  • Approved by Australian Road Authorities
