From new estates in Shell Cove and Flinders to established streets in Warilla, Barrack Heights and Oak Flats, Shellharbour homes need retaining walls that look good and hold up. Whether you're building new or fixing an old wall, we handle the excavation, engineering and build, with one point of contact.
On a new build, retaining walls are often left until the end, which costs more and holds up landscaping and fencing. If we're involved early, your boundary walls can be planned around the slab, the site cut and the driveway, and priced as one package. We work with owner-builders and with builders on handover.

Shellharbour City Council has its own rules for retaining walls, and new estates may also have estate design guidelines. We check both at your site assessment and can coordinate engineering and certification.
