Engineered to Stand the Ground

Concrete sleeper retaining walls give us the strongest balance of structure and finish for Wollongong blocks. Steel H-posts sit in engineered footings, and reinforced sleepers slot between them for a wall that will not rot, warp or attract termites. We set out every wall on site, keep posts plumb, and compact backfill in layers so nothing settles later.

Finishes run from smooth charcoal and sandstone through to stacked stone and timber grain textures, so the wall can recede or become a feature. Behind the face we install aggregate, geotextile and ag-line to a legal discharge point every time.

Where a block needs shaping first, our excavation and earthworks crew cuts the benches, and our landscaping protect the finished structure. To talk through your site with Retain by Theo, call 0417 661 224 for a free quote.
