The St George area rises from Botany Bay to ridges at Hurstville and Penshurst, then drops steeply to the Georges River at Oatley, Lugarno and Blakehurst. That mix of flat bayside blocks and steep riverside land means every job is different.
Typical St George retaining wall jobs
- Steep riverside blocks in Oatley, Lugarno, Connells Point and Blakehurst — tiered and often engineered walls.
- Boundary walls for new duplexes and knockdown-rebuilds across Hurstville, Kogarah and Bexley.
- Replacing leaning brick walls on post-war homes.
- Charcoal and sandstone-look sleeper walls for modern backyard makeovers.
What to know building here
River-front properties have foreshore building lines and sandstone close to the surface, which can mean rock drilling for posts. Bayside areas have sandier soils and, in places, a high water table — drainage design matters. We check the planning controls for your address before quoting.

Frequently asked questions
Do you build retaining walls in St George?
Yes. We build concrete sleeper, sandstone, timber, block and engineered retaining walls across St George, including Hurstville, Kogarah, Carlton, Allawah, Penshurst, Mortdale and surrounding suburbs.
Do I need council approval for a retaining wall in St George?
It depends on the height, location and what the wall supports. St George is covered by Georges River and Bayside Councils. Low walls meeting the NSW exempt development standards often don't need approval; taller or boundary walls usually do. We check the controls for your address — see our approval guide.
How much does a retaining wall cost in St George?
Most walls fall between roughly $300 and $1,400 per square metre of wall face depending on material, height and access. Tight access and rock can add cost. See our cost guide or ask for a free fixed quote.
