Saving a Neighbour's Yard

Our client reached out after realising that his fence and retaining wall were at the stafe that they needed to be replaced, at risk of falling over into the neighbour’s yard. They had already contacted numerous other construction companies without results, none wanting to take on the job due to concerns about danger from the sloped block.

M.O.S. Construction consulted with their engineer and designed a suitable retaining wall made from sturdy concrete sleepers which could take the weight of the earth from the other side, finishing it with brand new fencing on top for privacy.

While it was a very difficult job and required heavy equipment and a higher level of safety preparation, M.O.S. were able to get the work done within a reasonable timeframe, the customer was happy, and the neighbour was now safe. The photos for this job really speak for themselves!

A Sloped Block

Our client in Durack, a suburb in the south of Brisbane, was fed up looking at her front garden with overgrown grass and weeds. She asked what could be done, and we suggested a beautiful concrete sleeper retaining wall over two levels, each at one metre high.

This allowed our client to turn an unusable, weed-filled garden into a stunning front area that she can easily work in. It even had the added benefit of increasing privacy to the house by better defining the front of our client’s property from the council-owned verge.

Protection & Aesthetics

Over the years our client had experienced some terrifying times, with no less than three cars crashing into his corner-block fencing and into the side of his property. He asked for something that looks good and would protect him and his family.

M.O.S. drew up planning and the client was thrilled with the proposal. We built the wall out of 190-series Besser Blocks, completed with reinforced steel and concrete foundations and core fill. With the structure in place, our client decided upon render painted white, and finished it off with garden fencing between the piers.

Not only can a Besser Block wall be used to hold back earth that needs retaining, but it can provide a stunning boundary to your property, too, as seen with this job. Our client is happy and feels like he and his family are safe with this new wall.

A Leaning Wall in a Tough Location

This was a very complex job. The existing wall was on a very bad lean, and our customer wanted it demolished and a new concrete sleeper wall installed. It was next to a public walkway to the side and rear of the property, and the house was only 800mm away from the existing structure. There were pedestrian walkways surrounding the property, council trees not far away, gas utilities coming out of the side wall behind the fence, and water pipes underneath the ground. Each of these things provided extra concern and a high level of difficulty.

M.O.S. demolished the wall by cutting it with large demo saws into large squares of 1500 x 1500mm. These were then dropped and cut into smaller sizes so the excavator could lift them into the bins. A 1.7 ton excavator then ran the blocks to the bins, and the 5 ton excavator with the rock breaker was used to break up the foundations.

Overall it took eight working days, but was completed with no damage to the house, utilities, pipes, trees or surrounding pathways, and our customer was over the moon with the finished product.

50 Years of Pressure

This one was another very complex job. This 50-year-old wall was holding up a road behind it, and had buckled under the pressure that came from holding up so much busy land without any drainage. Cracking and bowing was very evident when M.O.S. Construction arrived to propose a solution.

When it came time to begin works, we demolished the old retaining wall – all the time successfully working around the NBN pole, existing gas lines and a huge tree. After demolition we started excavation, and that’s when we hit rock. After seven days with a five-ton machine drilling with the best auger on the market, we had holes 2400mm deep that would do their job of holding up the road for the next 100 years.

After excavation and drilling was complete, we installed 150uc posts in the ground and 100mm thick 3-bar reinforced concrete sleepers. We then installed 100mm agricultural pipe with sock and 8 tons of drainage stones. Finally this wall had drainage, relieving any future pressure weighing against it. Once this was back-filled, the poles were secured with mass concrete. Our client asked for us to finish off the job with the installation of a new timber fence to provide privacy.

Not only was this job complex, but it required extensive engineering and the use of some very strong specialised equipment.
