Retaining wall jobs around Geraldton

From Drummond Cove to Tarcoola Beach, these are the walls people ask about most.

  • Boundary walls with a fence on top

    Where your yard sits higher or lower than next door. In a windy town the fence on top matters as much as the wall.

  • Levelling a sloping block

    Cutting and filling a slope into flat lawn, a patio or a shed pad, sometimes over two or three steps.

  • Pool surrounds

    Holding back sand beside a pool and squaring up the levels for paving and the safety barrier.

  • Garden beds and front yards

    Low walls that edge a lawn or lift a garden bed out of the sand.

Wind, fences and walls

Geraldton's afternoons are windy. Bureau of Meteorology records for Geraldton Airport (1941 to 2010) average around 29 to 31 km/h at 3pm through December, January and February.

That matters for any wall with a fence on it. The fence catches the wind and passes the push down into the wall and its footing. The City of Greater Geraldton's retaining wall checklist lists wind on fences, along with driveways, pools, vehicles and buildings, as extra loads a wall may have to carry. A wall designed only to hold soil isn't automatically built for them.

The same checklist says a dividing fence may sit on the higher side of a boundary wall, and that a fence shouldn't be used to hold back soil unless it was designed to. If a fence is part of the plan, say so in your enquiry.

Sand, limestone and winter rain

The coastal limestone of Western Australia, known as the Tamala Limestone, runs from Shark Bay in the north to near Albany in the south, and Geraldton lies on that stretch of coast, and sand is common on blocks here.

Sand drains quickly but it's loose. It slips out through gaps, washes from under a base that wasn't compacted, and moves when it's soaked. Most of Geraldton's rain falls in late autumn and winter. The Bureau's averages for Geraldton Airport put about 444mm a year on the town, with June and July the wettest months at over 90mm each.

Add reticulation and downpipes, and water still collects behind walls here. That's why most walls include gravel, fabric and an ag pipe that carries water somewhere safe.

General information only. The builder will work out what your site needs.

How water moves through sand behind a retaining wall: it soaks down to a gravel drain and an ag pipe, which carries it away. Rain and reticulation Water soaks quicklydown through sand Ag pipe carries it to a safe outlet Gravel lets waterreach the pipe

Wall types you'll see in Geraldton

The right choice depends on height, space front to back, what sits on top and the look you're after. The builder who quotes can take you through the options for your yard.

Limestone blocks

Cut limestone blocks stacked in courses, usually stepped back a little as they rise. A natural fit for the sand-and-limestone country along this coast, and the look many Geraldton front yards already have.

Worth knowing

  • Each block is heavy, so machine access to the yard matters.
  • Gaps between blocks can leak sand unless they're packed or backed with fabric.
  • Height changes the design quickly, especially past 500mm.

Post and panel (concrete sleepers)

Concrete panels slotted between steel posts set in concrete. Slim front to back, so they suit narrow side setbacks and long straight runs along a boundary.

Worth knowing

  • The posts and their footings carry the load.
  • Fabric behind the panels stops fine sand escaping.
  • A fence can often sit on the high side if it's planned in.

Reinforced block

Hollow concrete blocks with steel and concrete fill on a proper footing. Chosen when a wall has to hold more, like a driveway, a slab or a building close to the top.

Worth knowing

  • Expect an engineered footing and steel layout.
  • Drainage behind the wall is part of the design.
  • Can be rendered to match the house.

City of Greater Geraldton rules

From 500mm, approvals come in. The City's retaining wall checklist (form BS12) says a building permit is needed for a wall 500mm or higher, for an addition to an existing wall, and for tiered walls with a combined height over 500mm. Development approval is needed for walls over 500mm and should be obtained before the building permit is lodged. Walls 500mm and over must be designed and certified by a structural engineer.

Boundaries and neighbours. A wall along a common boundary has to be built entirely within one property. Where work may encroach on or adversely affect the lot next door, the adjoining owner's consent is needed on a BA20 or BA20A form. The owner who changes the natural lie of the land is responsible for retaining the soil, and neighbours who have both changed levels may share that responsibility.

Check with the City before work starts. The BS12 retaining wall checklist is the place to begin, and the builder who quotes can usually tell you what they expect will be needed.

What moves the price of a wall

Nobody can give a fair price per metre without seeing the site. These are the things a quote is built from.

Height
The biggest single factor. Taller walls need more material, deeper footings and, from 500mm, an engineer's design.
Length and corners
More metres and more turns mean more blocks, more base and more labour.
Material and finish
Limestone, post and panel, and reinforced block all price differently, and so do capping and render.
Getting into the yard
A small machine through a wide gate is quicker than hand-carrying blocks down a side path.
Sand to move
Digging out a cut, carting away spare sand or bringing in fill all add to the job.
Loads on top
A fence, driveway, slab or pool near the top of the wall changes what it has to carry.
Drainage
Gravel, fabric, ag pipe and where the water is let out.
Approvals
Development approval, a building permit and engineering for walls 500mm and over.

Geraldton retaining wall questions

Do I need a building permit for a retaining wall in Geraldton?

For most walls you will. The City of Greater Geraldton's retaining wall checklist says a building permit is needed for a wall 500mm or higher, for an addition to an existing wall, and for tiered walls that add up to more than 500mm. It also says development approval is needed for walls over 500mm, and should be sorted before the building permit is lodged. Check with the City before work starts.

Does the wall need an engineer?

The City's checklist says walls 500mm and over must be designed and certified by a structural engineer. The builder who quotes can usually tell you how they handle that.

Can the wall sit on the boundary line?

The City's checklist says a retaining wall along a common boundary has to be built entirely within one property, not straddling the line. If work may encroach on or affect the lot next door, the adjoining owner's consent on a BA20 or BA20A form is needed.

Who pays for a wall between two blocks?

The City's checklist says the landowner who alters the natural lie of the land is responsible for retaining the soil. If both neighbours have changed their levels, they may be jointly responsible and may need to share the cost.

Can I put a fence on top of the wall?

Often, yes, if the wall is designed for it. A fence catches wind, and that load ends up on the wall. The City's checklist lists wind on fences as one of the extra loads a wall may have to carry, and says a fence shouldn't be used to hold back soil unless it was designed to. Mention any fence plans when you ask for a quote.

Do you build the wall yourselves?

No. Geraldton Retaining Walls is a local quote-matching service. We pass your enquiry to an independent local retaining wall builder who services Geraldton. They contact you, quote the job and do the work.

Does it cost anything to send an enquiry?

No. Sending an enquiry is free, and there's no obligation to go ahead with any quote.
