Why choose Orange Projects
We assess height, load and position on site and tell you what your wall is likely to need, without blanket promises.
Walls, steps, paving, fencing, decks and landscaping sequenced together instead of across several contractors.
Licence No. 15620733 and fully insured. Structural outdoor work is carried out under licence.
Ag pipe, gravel backfill and a sensible discharge point are part of the job, not an optional extra.
What is under the wall
Posts carry the load, so their footings need enough depth for the wall height and soil. As a rough guide, footings get deeper as the wall gets taller, and posts get closer together for heavier loads.
We set depth and spacing from the design, not by eye.
