RETAINING

walls and irrigation.

Retaining in Byron Bay & the Northern Rivers

Corten steel, sandstone boulders and reclaimed railway sleepers holding banks where they belong, and irrigation feeding the beds so you are not standing there with a hose.

A wall you cannot paint

The escarpment block at Suffolk Park is held by curved corten steel, cut into a slope you could not walk before we started. Corten rusts to its own finish and never needs painting, which matters on a wall that no one could get a ladder to anyway. The levels above and below it are the usable garden.

How we work

Half the blocks in this region are on a slope. A retaining wall turns ground you cannot use into a level you can, and it decides where the water goes for the next twenty years. Both matter more than what the wall is made of.

Drainage behind the wall is the part nobody sees and the part that fails. Aggregate, an ag line and somewhere for it to go. We build to that standard on a garden wall the same as a structural one, and we bring in an engineer where the height or the surcharge calls for it.

Questions we get asked

How high can a retaining wall be before it needs engineering?
In NSW, walls under about a metre with no surcharge above them are commonly exempt, but it depends on the council, the soil and what sits behind the wall. Byron and Ballina shires each have their own thresholds. We check yours before quoting, and where an engineer is needed we bring one in rather than guessing.
Why corten steel instead of timber or block?
Corten develops a stable rust layer and then stops, so it never needs painting, sealing or replacing. It is thin, which matters when you are trying not to lose garden width, and it takes a curve that block will not. Timber is warmer and cheaper up front. Block is heavier and more permanent. All three have their place and we build all three.
Do I really need irrigation in the Northern Rivers?
For lawn, usually not. For new planting through its first two summers, and for anything in a raised bed, pot or green wall, yes. Those dry out far faster than ground level beds and they are the plantings people lose. A small zoned system on a timer costs less than replacing a screening hedge twice.
