Retaining wall builders based in Gawler
May Paving is run by Brodie and Kayla May, a husband and wife team based in Gawler. Retaining walls are a core part of the work — a lot of blocks around Gawler, Hewett and the northern suburbs slope, and the wall is what makes the flat, usable yard possible.
A retaining wall is only as good as what you cannot see: the footing it sits on and the drainage behind it. We build both properly, because a wall that moves or holds water is a wall you end up paying for twice. Concrete blocks or natural stone — we work with whatever suits your block and your budget.
We are fully licensed and insured under Builder's Licence BL 355972, with over 10 years of hands-on experience building walls and the paving that runs up to them.

Retaining walls we build
From low garden walls to structural walls on sloping blocks — across Gawler and the northern suburbs.
Natural Stone & Boulder Walls
Natural stone and boulder walls for a softer, more established look — like the granite patio and boulder wall jobs in our gallery.
Garden Walls
Low walls that shape garden beds, hold levels and frame lawns — usually built together with edging, planting areas and paving.
Structural Walls on Sloped Blocks
Taller walls that turn a sloping block into flat, usable yard. We will tell you straight when a wall needs engineering or approval, and price it accordingly.
Drainage Behind Walls
Aggregate and drainage laid behind every wall so water gets out instead of pushing against it — the difference between a wall that lasts and one that leans.
Walls + Paving Together
The wall, the paving in front of it and the garden above it done as one job by one team, so the levels and the finish line up.
Retaining walls usually pair with paving or landscaping — see paving in Gawler, landscaping in Gawler, the full services page, or browse recent jobs in the project gallery.

Retaining walls — common questions
Do I need council approval for a retaining wall in SA?
As a general rule in South Australia, low garden walls under a metre often do not need approval, but taller walls, walls close to a boundary or driveway, and walls supporting a structure usually need development approval and engineering. Every block is different — we will tell you straight up whether your wall needs it and factor it into the quote.
How much does a retaining wall cost in Gawler?
It depends on the height and length of the wall, the material you choose, how much excavation and drainage is needed, and access to the site. Quotes are free with no obligation — call 0435 287 076 or send through your details and we will come and measure up.
What types of retaining walls do you build?
Concrete block walls and natural stone or boulder walls — from low garden walls that shape beds and lawns through to structural walls that hold a sloping block. We work with whatever material suits your property and budget.
Do retaining walls need drainage?
Yes. Water building up behind a wall is the most common reason walls lean and fail, so we lay aggregate and drainage behind every wall we build. It is not the part you see, but it is the part that decides how long the wall lasts.
Can you build the retaining wall and the paving together?
Yes — that is the way we prefer to work. The wall, the paving in front of it and the garden above it get planned to the same levels and built by the same team, so nothing has to be redone to make the pieces fit.
What areas do you cover?
We build retaining walls across Gawler and the northern Adelaide suburbs — Willaston, Evanston, Hewett, Smithfield, Munno Para, Blakeview, Craigmore, Elizabeth and Salisbury — plus the Barossa Valley and greater Adelaide.
