Replace Failed Retaining Wall – Cashmere

This new sandstone boulder retaining wall reaches a maximum height of 3.9 metres. A drainage layer of crushed aggregate is included behind the boulders to relieve the hydrostatic pressure which can cause premature failure of retaining walls.

Random sandstone slabs were used in the construction of this 74m long retaining wall in Cashmere near Joyner, Warner, Clear Mountain and Eatons Hill on the north-west outskirts of Brisbane. This engineer-designed wall replaces a failed concrete block retaining wall.

The base of the new wall is embedded in the undisturbed natural ground to a depth as determined by the engineer.

The property owners now enjoy peace of mind as their new wall has been built by a QBCC licenced contractor.

The retaining wall is now constructed, but it will be great to re-visit this property in 12 months to see how the sandstone boulder wall will blend into this beautiful environment. When the drainage systems are re-connected and the lawns and gardens are re-established, this native bushland retreat will be something to behold.

We didn’t make it back in 12 months, but this is what the site looks like about 5 years after the installation of the sandstone boulder wall. The water tanks have all been reinstated, gardens established and a new shed has been built. What a difference!! The sandstone wall hasn’t moved and it’s still the hero retaining the bank.

  • …the end result far exceeds my expectations

    I had a boulder wall completed a few months ago. It took me quite a while to make a decision and I had numerous questions for Glen during those months. Glen was most helpful and happily came out several times to answer my questions.

    Well, the end result far exceeds my expectations, no matter who visits my property, (friends or tradespeople) they are all amazed how well the wall has been built particularly the straight, level rows of boulders. They all say, who built this wall, gee they take pride in what they do.

    Each rock was carefully placed and if it was not the fit they were looking for down it came and another rock was selected. If you are considering a boulder wall then you should talk to Glen at Cornerstone Boulder Walls.

    From my experience they will offer honest factual guidance based on their years of experience and build you a wall that you will be extremely happy with.
