By the Handmade Concreting team, Perth concreters with 10+ years of local experience.

If you need experienced concreters in Scarborough, Handmade Concreting works across Scarborough and the surrounding northern coastal suburbs, delivering driveways, patios and slabs built specifically for the Indian Ocean salt-air environment.

Scarborough is one of Perth's most in-demand coastal suburbs right now. With median house prices sitting above $1.3M as of mid-2026 and a steady stream of knockdown-rebuilds replacing the old post-war cottages, the volume of concreting work here is significant. But concreting near the coast is genuinely different from work 15km inland. The salt air, the Spearwood sand and limestone soils, the tight infill blocks - all of it shapes how we design and pour a slab. Handmade Concreting has been working in coastal Perth long enough to know what holds up and what fails inside five years. This post covers what you actually need to know before getting a quote.

Salt air from the Indian Ocean accelerates chloride ingress into concrete, corroding the steel reinforcement inside and causing surface spalling. In Scarborough and other suburbs within 1km of the coast, we use increased concrete cover (50mm to the soil face rather than the standard 40mm), a low water-to-cement ratio mix, and UV-stable penetrating sealers reapplied every 2-3 years rather than the 3-5 year cycle typical of inland Perth suburbs like Morley or Balga.

Here is the science in plain language. Chloride ions carried on sea breezes settle on concrete surfaces and work their way through any micro-cracks or porous spots in the matrix. Once they reach the reinforcing steel, they break down the passive oxide layer that normally protects it. The steel rusts, expands, and cracks the concrete from inside. On a budget job poured to standard inland specs, you can start seeing spalling and rust staining on a Scarborough driveway within four or five years.

The fix is not complicated, but it has to be specified up front:

• Low water-to-cement ratio mix (typically 0.45 or lower) for a denser, less permeable matrix
• 50mm minimum cover over SL72 mesh on coastal-facing slabs
• UV-stable penetrating sealer - not a film sealer, which peels and traps moisture underneath
• Resealing every 2-3 years, with annual checks for salt bloom (white powdery deposits) on north-facing surfaces

Every coastal job we do in Scarborough is specified this way as standard. It is not an upsell - it is what the environment requires.

Exposed aggregate is the most popular and practical driveway finish in Scarborough. Its slip-resistant texture, salt-tolerant surface and natural stone tones suit the coastal architecture well. Honed concrete and liquid limestone are strong options for patios and alfresco areas where a refined finish is the priority.

Exposed aggregate is the most popular driveway finish in Scarborough, and for good reason. It is slip-resistant by nature, its textured surface is more forgiving of salt bloom than smooth broom-finish concrete, and the natural stone blends - sandy creams, warm greys, charcoal river stone - suit the casual coastal architecture of the suburb well. For a standard 60m² driveway, exposed aggregate runs $8,100-$8,700 excluding earthworks and sealing.

With a professional owner-occupier demographic investing seriously in their properties, we also see strong demand for honed concrete and liquid limestone on Scarborough patios and alfresco areas. Honed concrete delivers a smooth, refined finish that photographs beautifully against coastal landscaping. Liquid limestone - particularly the lighter tones from suppliers like Limecrete - keeps outdoor surfaces cool underfoot in the Perth summer and pairs naturally with the bleached, sun-washed aesthetic of a beach-adjacent home. A 60m² honed concrete driveway sits at $11,100-$11,700 for the slab itself.

For homeowners who want the look without the honed price point, coloured concrete at $100-$110/m² is worth considering - particularly in warm sandy or driftwood tones that connect to the coastal palette.

You can see the full range of options on our exposed aggregate page.

Scarborough's mix of legacy lots and tight infill blocks creates very different site conditions. Open older lots are straightforward, but knockdown-rebuild sites with 3-3.5 metre crossovers and boundary retaining walls on both sides require a concrete pump and careful pre-pour access planning.

Scarborough's housing mix creates very different concreting challenges depending on which era of property you are working on. Older post-war and 1960s brick-and-tile homes on large legacy lots (often 700-900m²) typically offer open access and straightforward pours. Knockdown-rebuild sites on subdivided lots and new infill developments are a different story - tight crossovers of 3-3.5 metres, boundary retaining walls on both sides, and neighbouring active builds that restrict where a concrete truck can sit.

On those constrained sites, a concrete pump is not optional - it is necessary. A pump can reach up to 30 metres from the truck position, which makes most Scarborough infill lots workable even with a single narrow crossover. We plan site access before every pour rather than arriving and figuring it out on the day. That planning includes where the truck parks, how far the line runs, and whether adjacent builds or street trees create any obstruction.

Scarborough's Spearwood dune soils add another variable. Yellow-brown sands with limestone fragments and potential Tamala Limestone outcroppings mean the sub-base preparation is not always predictable. We have hit solid limestone on blocks in the older parts of Scarborough that needed breaking out and relevelling before we could form up - something you would never encounter on a Bassendean sand site further east. Free-draining granular sub-base preparation is essential here for long-term slab stability, and we never skip it.

If you are planning a concrete driveway on a knockdown-rebuild in Scarborough, it is worth reading our post on Concreters Karrinyup: Premium Concrete Finishes for Perth Homes- a neighbouring suburb with many of the same soil and access challenges.

For a standard 60m² driveway in Scarborough, exposed aggregate concrete costs $8,100-$8,700, honed concrete $11,100-$11,700, standard grey $5,400-$6,000, and coloured concrete $6,000-$6,600. These prices include steel reinforcement, SL72 mesh, chairs and setup. Earthworks, acid washing and sealing are quoted separately based on site conditions.

The honest answer on cost is that coastal spec adds a small but real premium over a standard inland pour. The increased cover, the lower w/c ratio mix, and the correct sealer all cost a little more than a basic job. What they buy you is a driveway that does not start showing rust staining and surface spalling by year five. In a suburb where the average home is worth over $1.3M, cutting corners on a $600 concrete upgrade makes no financial sense.

Earthworks vary significantly by site. If your block has solid limestone close to the surface - which is not uncommon in Scarborough - breaking it out adds time and cost. We quote earthworks after a site visit, not from a photo. Every quote we provide is specific to the actual conditions on your block, not a figure pulled from a per-metre rate calculator.

We have been concreting across Perth's northern coastal suburbs for over 10 years. Our team is fully licensed and insured, and we carry a consistent 5-star rating built on straightforward work and honest communication. We have supplier relationships with quality finish partners including Limecrete, which gives us reliable access to the liquid limestone products popular in Scarborough and surrounding suburbs. On a practical level, we know what Scarborough's soil throws up - literally - and we plan around it rather than getting surprised on the day. That local experience is the difference between a driveway that looks great at handover and one that still looks great in 2031.

We regularly work across Scarborough's neighbouring suburbs throughout the City of Stirling and the northern coastal corridor. If your project is just outside Scarborough, we most likely cover your area.

Does salt air from the ocean actually damage concrete driveways in Scarborough?

Yes - salt particles carried on Indian Ocean sea breezes penetrate porous concrete, reach the steel reinforcement inside, and trigger a corrosion process called chloride-induced corrosion that causes rust staining and surface spalling. In Scarborough, this process happens faster than in inland Perth suburbs because of the consistent onshore wind. The engineering response is a denser, lower water-to-cement ratio mix, 50mm minimum steel cover on coastal-facing slabs, and a UV-stable penetrating sealer reapplied every 2-3 years - all of which we specify as standard on every Scarborough job.

How often does concrete need to be resealed in Scarborough compared to inland Perth suburbs?

Coastal Scarborough concrete should be resealed every 2-3 years, compared to the 3-5 year cycle typical of inland Perth suburbs. We recommend a UV-stable penetrating sealer rather than a surface film sealer - film sealers can peel and trap moisture, which accelerates salt damage on north-facing driveways that cop the most sun and salt exposure. Do a visual check annually for salt bloom, which shows up as white powdery deposits on the surface, and for any early spalling around the edges.

Is exposed aggregate the right driveway finish for a Scarborough coastal home?

Exposed aggregate is the most practical and popular driveway finish in Scarborough for several reasons. Its textured surface is inherently slip-resistant - useful in a suburb where people walk to the beach in thongs and come back wet. The natural stone aggregate in sandy cream, warm grey and charcoal river stone blends complements coastal architecture and low-maintenance landscaping. Its textured surface also handles salt bloom more gracefully than smooth broom-finish concrete, where white deposits are immediately visible. At $135-$145/m², it sits in a strong mid-range position for the quality it delivers.

Can a concreter access my Scarborough knockdown-rebuild site if the crossover is narrow?

Narrow crossovers of 3-3.5 metres on Scarborough infill sites are something we handle routinely. A concrete pump solves most access problems by allowing the truck to park on the street while the pump line reaches up to 30 metres into the site. We assess access at every site before scheduling the pour - crossover width, boundary retaining walls, neighbouring builds, and street parking availability all factor into the plan. It is not exceptional to need a pump on a Scarborough site; it is just part of working in a suburb with a high density of infill and knockdown-rebuild projects.

What soil type is Scarborough built on, and how does it affect a concrete slab?

Scarborough sits on the Spearwood dune system - yellow-brown sands with limestone fragments and potential Tamala Limestone outcroppings close to the surface. This gives higher and more variable bearing capacity than the Bassendean sands further east, but it means excavation can hit solid rock on some blocks, requiring breaking out and relevelling before formwork can be set. Free-draining granular sub-base preparation is essential for long-term slab stability on these soils. Local site knowledge matters here - we have worked enough Scarborough blocks to know when to expect limestone and to price earthworks accordingly.
