Concrete Sleeper Retaining Walls
A strong, engineered option for the steep, sandstone-based blocks common through Longueville.
Read more →We build concrete sleeper, timber, sandstone and gabion retaining walls across Longueville, the small peninsula suburb bounded by the Lane Cove River, Woodford Bay and Long Bay. Like most of this stretch of the harbour, Longueville sits on Hawkesbury sandstone, so shallow bedrock and steep foreshore drops are common on blocks running down toward the water. What sets this suburb apart is its foreshore vegetation. In November 2023, more than 290 trees from a nationally significant plant community were illegally cleared on the Woodford Bay foreshore, and council has been actively monitoring the site's regeneration ever since.
That kind of scrutiny means any retaining wall proposed near Longueville's foreshore needs to be planned around the vegetation, not just the slope. Get in touch and we'll help you understand what that means for your property.

A natural material that sits comfortably against the peninsula's established gardens and foreshore bushland.

Built from the same stone found under most Longueville blocks, a genuine match for the local landscape.

A permeable choice for foreshore-facing blocks, letting water pass through rather than pushing against a solid structure.
Read more →Longueville's foreshore is a genuinely sensitive piece of ground, and we design with that in mind rather than treating every peninsula block the same as anywhere else on the harbour. That means siting a wall to keep clear of established foreshore vegetation, particularly on riverfront or bay-facing blocks where council has shown it's watching this land closely. We also factor in the foreshore building line controls that apply to some Longueville properties before recommending where and how a wall gets built.
Likely, and on a Longueville foreshore block, that approval can involve more than the usual height and setback checks. Given the confirmed sensitivity of the Woodford Bay vegetation, a wall near the foreshore may need extra consideration for its impact on nearby plant life.
Yes, and on a tight peninsula suburb like Longueville, that often means working close to both a boundary and an established foreshore garden. We confirm boundary lines and keep neighbours in the loop before work starts.
Yes, every wall we build gets an engineered design, which matters on Longueville's sandstone-based, foreshore-adjacent blocks where getting the footing right the first time counts.
It depends on the block, and a foreshore-adjacent Longueville property can take longer if vegetation or building line considerations need to be worked through first. We'll give you a clear timeframe once we've assessed your site.
Longueville's foreshore position makes it one of the more specific builds on the peninsula, and we plan around the vegetation and the slope alike. Get in touch and we'll design a wall that respects both.
