Auckland Boulder Retaining Walls

Boulder walls need machinery, and the right machinery for your site. We've got excavators and attachments that can lift and place serious weight, and we size the machine to your access rather than turning up with whatever was in the yard.

Placing rock well is a genuine skill. Every boulder has a face that sits flat and a face that rocks, and an operator who takes the time to find it builds a wall that stays tight. One who doesn't builds a wall with gaps that soil washes straight through.

We build across Auckland's hillier suburbs regularly, so we're comfortable working on slopes and tight access that put some contractors off. If a truck can't reach the wall line, we'll work out how to get the rock there.

We get the batter right. A boulder wall that stands vertical is relying entirely on friction, and over time it walks forward. Leaning the courses back into the slope is what turns a stack of rock into a structure, and the correct angle depends on your soil and height.

We key the base course into the ground rather than sitting it on the surface. That first row carries everything above it, and burying part of it is cheap insurance against the whole wall creeping outward.

We also think about what happens after the machinery leaves. Boulder walls look best once planting has softened the gaps, so we leave planting pockets where they make sense and can co-ordinate with your landscaper on what goes in.
