Sandstone Boulder Walls

Sandstone Boulder Walls

Cornerstone Boulder Walls has been building boulder retaining walls in the Brisbane area for more than 30 years. Owner Glen Cadoo has specialised in general earthmoving and constructing rock retaining walls for most of his working life.

He uses Helidon sandstone, natural granite boulders and concrete blocks to build high quality rock walls. Glen is fully licensed and all walls are engineer certified.

Cornerstone Boulder Walls has completed many projects …both large and small. Larger projects include retaining all building allotments in a complete property subdivision. Many commercial and domestic builders must establish a secure building pad with retaining walls. Rock retaining walls provide a very effective solution and the company is often commissioned for this work.

Homeowners and landscaping contractors also engage Cornerstone to place sandstone blocks as small retaining walls, garden edging and sandstone steps. Placement of natural granite rocks and boulders in various landscaping projects has also become very popular.

A recent project completed in Cashmere. A failed block retaining wall was replaced with a random sandstone slab wall.

This review is long overdue but 11 years ago Glen and his team built a (small for them), 2m high x about 30m long boundary line retaining wall and 3 smaller retaining walls and I could not be happier with their workmanship. The “exacting fit” of every boulder is frankly impressive! Everything looks as “precise and perfect” today as they did when they were first built.

In 2007, Cornerstone Boulder Walls built the retaining walls to secure the house pad prior to the construction of our home. This involved 3 major 2m high walls - two 40m long and one 60m long. It was amazing to watch Glen work as he assembled a 3D jigsaw puzzle. He has an incredible ability to look at a pile of rocks, select the right stone, spin it around and put it in place perfectly matching what was needed next. In the 14 years since, there has been no movement or change in the walls and it has been a very attractive and stable platform for our house. True craftsmen are hard to come by, but Glen is one of them. We got him back to do some cut sandstone steps in 2018 and they are fantastic also!

Glen did a terrific job excavating our front driveway and building a sandstone rock wall and sandstone stairs to our front door. He is a master of the excavator, nudging each stone in right place to make the perfect rock wall. He is professional, was able to guide us through the build process and respond to our queries quickly. Highly recommend Glen if you need some excavation/ rock wall work done at your place.

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.
