Retaining Walls

Retaining work starts underground. Accurate excavation, correctly bored post holes and proper drainage behind the wall are what keep it straight and stable years later.

Frequently asked questions

Do walls need engineering?

Height, load and location determine that, and council requirements vary. We will tell you when a design or permit is likely to be needed.

Can you do excavation only?

Yes — many builders and landscapers use us for the excavation and post holes and build the wall themselves.
