Hold the slope. Reclaim the yard.
Engineered sleeper, block and sandstone retaining walls that turn an awkward, unusable slope into flat, family-friendly space, built to stand the test of time and the Sydney weather.
From first sketch to final walk-through, you are looked after the whole way.
Thanks, that's booked in.
We'll call you back today from a Sydney mobile to lock in your site visit.
Built to hold, designed to look the part.
A retaining wall does two jobs at once: it has to hold back the ground for decades, and it has to look like it belongs in your garden. We build for both, with proper engineering and drainage behind the wall and a finish that suits the rest of the space.
Every wall is priced in a fixed written quote before any work starts and backed by a 12-month workmanship warranty. Where a wall needs engineering or council sign-off, we flag it at the site visit and handle the paperwork for you.
From cut slope to finished wall.
Sleeper walls
Treated timber and hardwood sleeper walls, a clean and cost-effective way to terrace a sloping yard.
Block walls
Reinforced besser and masonry block walls, rendered or capped, for height and serious load-holding.
Sandstone walls
Natural sandstone block and log walls for a premium, characterful finish that suits Sydney gardens.
Drainage
Ag drains, gravel backfill and weep holes done properly behind the wall, so water never builds up.
Engineering & approvals
Where height or load needs it, we arrange engineering and handle certifier liaison for you.
Steps & levels
Integrated steps and terracing so the new levels are usable, safe and easy to move between.
