Amazing product and team effort in installation! We had our large backyard transformed by Leon and the team and we could not be happier! From start to finish these guys were an absolute pleasure to deal with and nothing was ever an issue for them! We will be using them again in the future and would highly recommend them to anyone! Thanks again.

FAQS

Do you outsource your engineering service?

Yes, we are proudly partnered with Engenuity Engineering & Structerre Consulting.

Can you engineer for residential projects?

Yes. Our design team are more than happy to assist you to create the best possible retaining wall solution for your residential needs.

Why would I need an engineered solution?

Major commercial and industrial construction projects need retaining wall solutions tailored specifically to suit the size of the site and to meet specific design requirements of the landscape architects. However, bespoke designs are often required for residential projects where the terrain or unique geographical requirements will not be met by a standard solution.

How long will it take to engineer my bespoke retaining wall needs?

Depending on the size and difficulty of the project, our engineering service can design your project in as little as a week before you approve it. We then manufacture your retaining wall components to suit.
