Our process

Free on-site consultation & quote

We start with a site visit to assess wall height, ground conditions, slope, access, and drainage requirements. This allows us to recommend the most suitable block retaining wall system and provide a clear, site-specific quote.

System selection & design

We select the appropriate block or keystone system and design the wall based on site conditions, retained load, and drainage requirements. Where required, we advise on engineering or consent to ensure the wall is compliant and fit for purpose.

Construction

The site is excavated and a compacted base is prepared before blocks are installed and reinforced where required. Proper drainage is included as standard to manage water pressure and ensure long-term stability.

Final inspection

Once complete, the wall is inspected to confirm it is stable, aligned correctly, and finished cleanly before handover.

Our work

Why choose a block retaining wall?

Strong and reliable

Block retaining wall systems are designed to interlock and work together, creating a stable structure capable of handling significant soil pressure.

Flexible system design

Modular blocks allow for stepped, curved, or tiered designs, making them adaptable to a wide range of site layouts and landscaping plans.

Consistent appearance

Block retaining walls offer a uniform, clean finish that suits modern outdoor spaces, with a range of colours and textures available.

Excellent drainage performance

Segmental block systems are designed to manage water effectively, reducing pressure behind the wall and improving long-term performance.

Reinforced where required

Block retaining walls can be reinforced and engineered for taller or load-bearing applications, providing added strength when site conditions demand it.

Balanced cost option

Block retaining walls typically sit between timber and concrete in terms of cost, offering a strong balance of durability, appearance, and value.

Client testimonials

Pb Pb

Great team to deal with - friendly, and easy to communicate with. They replaced our retaining wall and completed a new shared driveway with our neighbours on what was a very challenging site. The quote remained fixed throughout the project, and they even completed finishing touches we didn’t expect. Well done - from Beach Haven

Marcus B

The team at TCG did a great job of our area. We had 240m2 of concrete plus an 8m retaining wall completed. Very prompt and were always contactable during the process.

Shane and his team at TCG did a phenomenal job with our retaining wall. Having the added element of geothermal water, Shane was quick to come up with a solution that would stand the test of time and within our budget. There were a few unexpected hurdles along the way; being a job that included a waterway, but with a solution focused mindset, this was no challenge for the team... We are beyond happy with our final product and can't thank the team at TCG enough! Absolutely recommend!!

Isha K

I can't recommend TCG highly enough! Shane and his team provided impeccable service from start to finish. Their communication was outstanding, keeping us informed every step of the way. The quality of their workmanship on our earthworks, retaining walls, and concrete driveway for our family home was exceptional.

Shane and team did an amazing job transforming our unused grass bank into much needed parking space for the family. The whole project was quick and easy - no stress and looks great. Great customer service, communication was great - nothing was too much trouble. Will definitely use TCG for future projects 🙂

Shane and his team were honestly the best contractors that we have ever worked with. Their work ethic and communication is absolutely top notch. Shane was true to his word on all occasions and was professional through the whole job. We are thrilled with the final outcome of our new retaining wall and railing plus all the earthwork that was completed. We honestly would recommend TCG group for any projects no matter how big. Our job was huge and somehow they managed to make it look so easy.

Elliott C

They did my pool and retaining walls, was hard to find a company that would do everything I needed. 1 company doing everything rather then the mess of 5 different companies is what I liked. I would recommend to anyone considering using this company. Pricing was very fair and reasonable. Cheers Shane and the team!
