Exposed aggregate
Architectural aggregate finishes sourced from premium Australian suppliers including Boral, Limecrete, WA Premix and Heidelberg Materials. Available mixes include Coral White, Eucalyptus White and Kaajani Grey among many others — see samples in person at our supplier partners in East Perth, Bibra Lake and Osborne Park before committing.

Honed & polished concrete
Honed and polished concrete are architectural finishes from the same premium supply chain as exposed aggregate. The difference is in how the surface is processed: honed concrete is mechanically ground to a refined matte finish and sealed. Both finishes start with the same architectural mix design. Polished concrete takes the mechanical grinding process to a high-gloss finish, typically used for interior ground slabs, garages and undercover alfrescos. Decorative ground slabs are poured at 32MPa to accommodate the polishing process.
Our work in Harrisdale
Alfresco and garage slab for a builder client — enquiry to completion in just over a week
For a builder client working in Harrisdale, Colacrete completed a grey concrete alfresco area and garage slab — from the first phone call to a finished job on site in just over a week.
That turnaround matters in Harrisdale's active new build market. Builder clients don't have flexibility in their construction schedules — the concreters come in, do their work, and leave the site in condition for the next trades to follow. A concreter who responds slowly to a quote request, takes weeks to schedule, or holds up the programme because the finish isn't right is a problem that costs the builder time and money. Colacrete's ability to move quickly — getting on site fast, getting the job done right, and getting out without issues — is what earns repeat work and referrals from builder clients across Perth's southern growth corridor.
The scope on this Harrisdale job covered both the alfresco entertaining area and the garage slab. Each area was prepared individually. Both slabs were poured in standard grey concrete to our full specification: 100mm thick, 25MPa concrete strength, SL62 reinforcing mesh . Concrete was batched at the plant and arrived at the correct slump.
The alfresco and garage were delivered on time and to the builder's specification, leaving the site ready for the next stage of the build without delay.

Why Harrisdale homeowners and builders choose Colacrete
Harrisdale is a contemporary estate suburb within the City of Armadale — part of Perth's southern growth corridor that stretches from Cockburn through to the Byford and Serpentine fringe. The suburb is predominantly made up of modern homes built from the mid-2000s onwards, with a housing stock that leans toward rendered facades, double garages and well-designed outdoor living areas. Soils in Harrisdale are predominantly sandy with some clay content as the terrain transitions from the coastal plain toward the Darling Scarp — a mixed profile that makes site-specific subgrade assessment important, particularly on larger pours. Builder and developer activity in the area remains strong, generating consistent demand for garage slabs, alfresco areas, driveways and the full outdoor concrete package that finishes a new home.
Colacrete is a member of the Housing Industry Australia (HIA), Master Builders Association (MBA) and Concrete Institute of Australia (CIA). Eddie brings an engineering background in civil and construction management alongside long-standing experience across concreting and general construction projects spanning a wide variety of disciplines, scales and scopes.

"Eddie and his team did our crossover in Bassendean. Superb service, with very clear communication as to what was happening and when. He also worked to our local council's specifications which made the whole process much easier. The final product looks great. Highly recommended."

A building permit is generally required for a garage structure in Harrisdale — the concrete slab is part of that permitted scope. Covered alfresco areas typically also require a building permit depending on the structure type, size and proximity to boundaries. Uncovered concrete patio areas may not require a permit depending on size. Crossovers require City of Armadale approval separately. We advise on what approvals apply to your specific scope during the site visit and quoting process.
-
Harrisdale's contemporary rendered homes and double garage designs suit a range of finishes. For driveways, exposed aggregate in clean neutral tones — Limecrete's Eucalyptus White or Coral White are particularly popular in the southern corridor's estate suburbs — complements the modern home aesthetic well. Grey concrete remains the practical and cost-effective choice for garage slabs and functional areas. Honed concrete is increasingly popular for alfresco areas on Harrisdale homes where a refined indoor-outdoor finish is the brief.

For builder clients with active construction programmes, speed of response and scheduling is critical. Our recent Harrisdale project went from first enquiry through quoting to job completion in just over a week — the kind of turnaround that keeps builds on programme. Response time and scheduling capacity depend on our current workload, but we prioritise moving quickly for builder clients where the concrete is on the critical path. Contact us to discuss your timeline.
