      Sustainable foundations provide a significant cost benefit in replacing the damaged sign post by re-using the existing footing.  Our selection is not based on price alone, also the safety & saving aspects. The Smart Taper-lock allows the quick replacement of posts, with no further effort required to the base and reduces risk to employees by reducing time spent exposed to traffic!”  MRWA



      CHS  posts have been approved for securing MRWA Traffic signage in all regions (including cyclone zones). Let us quote- cheaper, more sustainable easier to install and far cheaper to maintain.

      Post Selection MRWA

      Now you can install MRWA sign-posts only 350 mm deep using Smart Sustainable Foundations- no need to dial before you dig. Sockets can be simply positioned upright when pouring concrete foundations and instead of taking weeks- signage can be installed in seconds. We can also supply the sign-posts and you will love our prices!


      The Taper-lock method (Smart Sustainable Foundations) for fixing the sign post may be used as an alternative by core drilling the surface (or removing the pavers to install the socket in the case of a paved area).  The method of installation shall be as recommended by the manufacturer.  MRWA Specs 601 Signs

      8.2.2 Sign posts
      For signs less than 1m² in area, the post size is generally 50NB x 3.2mm CHS. Refer to Appendix. B for determination of post sizes suitable for larger signs or heights.

      8.2.5 Posts in sleeves
      There are certain situations where it is advisable to install the post into a sleeve inserted into the footing, such as:
      1. Where a sign is located on an urban median strip where it may be struck frequently.
      2. Where it may need to be removed occasionally, to accommodate the swept path of over-dimensioned vehicles when turning.

      This arrangement is only appropriate for small posts up to 50mm nominal bore (60 O.D. CHS Posts). Details of a typical sleeve assembly are presented in Drawing No. 1368 (Appendix D). Variations on the basic theme are just as effective. "I would consider that your Smart Sustainable Foundations have an 'as-of-right' approval on this basis" John .C.Douglas Qld MR
