Retaining Walls in Gold Coast

Whilst treated pine sleeper retaining walls are the main retaining wall that clients ask for, usually for price, we have also done, block retaining walls, rock and sandstone walls. I would like to add that for all of these walls proper drainage behind is a must especially sleeper retaining walls. If it is not used compaction behind the wall can lead to premature rotting and decay of the wood. Or also it will place pressure on the wall and to lead to its collapse.

Roseville

A job done for a client in Sydney. Larger sandstone blocks were personally selected up to 900mm high. A foundation trench was made to place the the blocks to help hold them upright. Also the faces were matched for uniformity and given a 5° lean.

The upper level varied between 650 and 900mm and the second tier was between 350 and 450mm high. There were also some edging dividers used in various other places around 10mm high to divide garden and paved area, and also others used as steps to help get rid of some of the leftover sandstone pieces.

Sandstone is usually an easy material to mould to the needed shape, and can usually be done with just a bolster and hammer

Below is a complex sloped block. The clients wanted more useable room for themselves.

It works started with an upper area retaining wall at the back step of the house, to give more useable area by the back door. The return or lower side of the wall was keyed into the existing garden retaining wall for them consistency.

The next stage was to create a lower entertainment area. To achieve this there was a 2 tiered garden area with 1.8m horizontal area between the upper and lower wall. The lower wall 6 x 6m was placed to get a flat pad for the entertainment area. There are various photos from 3 years after the project completion

On this job one thing led to another. The sleeper retaining wall was previously an unretained slope, which in heavy rain would let soil slide under the small houses foundations. It was also good to do this to divert the water away from the house instead of toward it.

After doing the patio, which was also previously sloping ground there was a half a metre fall at the end that needed to be retained. The rocks found on site were used. A 15mm concrete backing was placed behind the rocks and while still wet the rocks were attached to the concrete. The joints between the rocks were filled with oxide coloured cement. Both to add adhesion and strength to the rocks, and also to not provide crevices for any unwanted vermin.
