Frequently Asked Questions

What is SureWall?

SureWall is a retaining wall system that uses steel posts and timber rails to generate an aesthetically pleasing, flush finished, non-obtrusive retaining wall system that is very quick and easy to install by any able-bodied DIY person. This innovative system also has significant labour savings due to minimum excavation.

How thick do the timber sleepers need to be?

The posts are 65mm wide and a 50mm sleeper is the best fit. This is so there is some room to move as the timber shrinks and swells.

How far apart should my posts be?

This is all dependant on your DIY project as well as the weight that is behind the wall. If a larger retaining wall is being built, then it is recommended to use more posts and less sleeper spacing to spread the weight on the wall structure. As an indication 1200mm is quite a common length.

Handy Tips

  • When installing SureWall, concrete one post at a time adding sleepers as you go to ensure a straight wall
  • For a different look, add a layer of timber capping to the top of the wall – it makes for great seating too
  • Designed with 15° tolerance, so you can create ‘curved’ walls at special angles
