Slipping Soil, Bulging Sleepers and Council Red Tape Make Slopes a Daily Worry

Cracked brick walls, leaning timber sleepers or sudden wash‑outs after a Brisbane downpour aren’t just eyesores, they threaten buildings, invite council fines, and steal usable yard space.

Add mandatory engineering certificates, excavation logistics and waterfront setback rules, and it’s no surprise many garden retaining wall projects stall before they start.

Retaining Walls Turn Risky Slopes into Safe, Usable Space

Our certified team designs, builds and warrants every wall, so you can relax knowing your yard is secure for decades to come.

  • Retaining walls with concrete footings, steel posts and geo-grid reinforcement stop cracks, bulges and collapses for good.
  • Terraced retaining walls reclaim sloped land, creating level zones for lawns, kids’ play, pools or outdoor entertaining.
  • Smart retaining wall drainage with ag-pipe, scoria and weep holes protects your property by relieving pressure and directing water away.
  • Choose retaining walls in finishes like concrete sleepers, sandstone or rendered masonry to lift your property’s look and value.
  • From excavation to landscaping, your entire retaining wall build is managed by one insured, experienced crew, no juggling tradies.

1300 4 Gardening Reviews

After a very hot summer of rain and heat my garden has really got away from me. 1300 4 Gardening came the next day to give a quote and in two weeks as scheduled two very helpful gardeners arrived on time and worked hard all day to give it a cared for neat look. I will certainly use them for any future work . to improve things colour and 1300 4 Gardening had a very efficient communication system. Staff are incredibly polite and pleasant and stay in touch and keep one informed. The payment system is efficient and safe.
Very happy.

I have been trying to maintain a section of my yard for months but the plants and weeds seem to grow faster than I could clear. I knew I needed help from the professionals at 1300 4 gardening got the quote which was reasonable and within my budget. I was new customer and they were extremely helpful and made an appointment within a week. Lachlan got right to work and when I returned from my job I was very impressed with the quality and pace I in which he worked achieving great results that would have taken me many weekends. Amazing job Lachlan and thanks to the team. Definitely recommend their services to others and they are coming back to do the front yard soon.

We required a fence line of Lily Pilly trees to be hedged. They belong to our neighbour and overhang into our pool yard. They are very tall as the neighbour has never pruned them.

The end result was perfect. They were cut back to the fence line. A tremendous amount of leaf litter and branches needed gathering up after hedging. Excellent clean up job. Nigel and Aidan did a fabulous job. Thanks for the great effort guys.

I have been using 1 300 4 Gardening to regularly trim our increasingly tall hedges and maintain various other shrubs around our garden for over 8 years. Lachlan, always friendly, and most recently Sean too, are very professional and thorough. Lachlan always remembers from visit to visit what needs to be done and I leave it up to him to get it done - which he always does. The hedges around our pool are very high but Lachlan, skillfully, keeps them healthy, straight and true. It is not an easy job.

I have been using 13004gardening for many years now. They have always done a great job at a good price. The last couple of times I've had Lachlan trim my hedges and he has done a great job. The yard is cleaned up, even the pool. I'll keep using 13004gardening for my hedges and do not hesitate recommending them for your gardening needs. 🙂
Margie Mulligan
Lachlan and Stephen attended our property for the first time and made a very good impression. They trimmed the hedge and weeded the inside yard and mowed and trimmed our outside half acre - it is the best it has looked for many years. Importantly the cleanup was excellent. We look forward to a long association.
