Avalon and the northern end of the Northern Beaches is retaining wall country. The steep blocks running down to the beaches mean most properties have multiple levels of retaining, and many of the old walls are failing. Salt air plus hilly terrain plus sandy soil is a hard combination for any wall.
We build and repair retaining walls with proper drainage — ag pipes, drainage blankets, weep holes. That's what makes the difference between a 50-year wall and a 10-year wall. Stone is our specialty, whether it's natural sandstone blocks or engineered block faced with stone veneer.
We also do a lot of coastal masonry repair up here — rendered homes with salt damage, brick walls that have lost their mortar, concrete steps and paths that have failed. The right materials and proper detailing is what makes coastal work last.
What Avalon homes and buildings need
Avalon has a mix of older homes, newer architect-designed builds and beachfront apartments. Steep, often sandy blocks mean retaining walls are everywhere. Salt air affects everything within a few hundred metres of the beach. Many properties have extensive stonework — retaining, garden walls, pool surrounds, paving.

Common Questions — Avalon
My retaining wall is leaning. Can it be fixed without full demolition?
Sometimes. If the foundation is sound and the lean is minor, we can stabilise with drainage improvements and tie-backs. If the wall is badly damaged or poorly founded, rebuilding is more cost-effective long-term.
What's the right stone for an Avalon retaining wall?
Most properties match the local Sydney sandstone character. We can supply natural sandstone blocks in a range of finishes. For engineered walls, concrete block with a sandstone veneer gives strength plus the right look.
How deep does a retaining wall footing need to be?
Depends on wall height and soil. For a 1m wall on stable ground, often 500-700mm. For taller walls or sandy soil, often deeper with wider pads. We engineer each wall for its specific site.
