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.

Cavity fill and suspended slab for a commercial office extension — structural concrete to engineering specification
In Maddington, Colacrete completed the structural concrete scope for a commercial office extension for a builder client: cavity fill to the concrete masonry block walls and a suspended slab at over 200mm thickness. The ground floor slab is a subsequent stage of this project, to be completed as the build progresses.
Cavity fill
The cavity fill scope involved pumping concrete into the hollow cores of the concrete masonry block walls across the relevant area of the extension. Filling the cavities of block walls with concrete increases the compressive strength and lateral stability of the wall system — converting what would otherwise be hollow-core block construction into a solid, mass-concrete wall capable of carrying greater loads and providing better structural performance. The cavity fill was treated as a separate operation to the suspended slab, completed in its own stage.
Suspended slab — 200mm
The suspended slab was poured at over 200mm thickness — a substantially heavier specification than a standard residential suspended slab, reflecting the commercial loading requirements of the office extension. A 200mm suspended slab carries greater imposed floor loads than a residential floor and requires a correspondingly robust structural specification. Colacrete poured the concrete to the engineer's specified mix and thickness. Back propping beneath the slab — the temporary propping system that supports the slab from below during and after the pour while the concrete gains strength — was managed by others on this project; Colacrete's scope was the concrete placement and finish.
The Colacrete standard
Build to spec
Where a licensed structural engineer has specified drawings, Colacrete works to those specifications. If no drawings or specifications are provided, we work to industry standards.
Communication
We pride ourselves on our prompt communication with all our clients. Not only do we aim to provide quotes within 24-48 hours, but we also keep our clients well informed before, during and after the works.
Our experience
We are owner-operated, and our director comes from an engineering background, having graduated from Curtin University and having worked as an engineer for several years. He also comes from a concreting family, with concreting experience spanning decades.
Why Maddington homeowners and builders choose Colacrete
Maddington sits within the City of Gosnells in Perth's south-eastern corridor — a suburb with a strong light industrial and commercial character alongside established residential areas. The combination of residential and commercial land use generates a diverse concrete scope: house slabs and driveways for residential clients, and structural and commercial concrete for the builders and developers active in the suburb's commercial precincts. Soil conditions in Maddington vary across the suburb — sandy soils consistent with the coastal plain are present in residential areas, while fill and disturbed ground are common on commercial and industrial sites where previous development activity has altered the subgrade. For structural and commercial scopes, this variability makes engineering input on footing and slab design important.
Colacrete's capability spans both the residential and structural commercial ends of the concrete market — from a residential driveway to a 200mm commercial suspended slab with cavity fill. The engineering background that underpins our structural capability is the same on every job regardless of scope type.
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.

Colacrete's pricing is based on job scope, site conditions, finish selection and access. Visit our service pages for more information (including our FAQ section):
Standard grey concrete including for house slabs (including suspended slabs), driveways, crossovers, footpaths
Exposed aggregate including for driveways, pool surrounds, footpaths and outdoor living areas
Polished concrete including for garages, alfrescos and patios, indoor living spaces, feature rooms and commercial fitouts and offices
Honed concrete including for pool surrounds, outdoor entertaining spaces, alfrescos, patios and garages
Liquid limestone including for driveways, pool surrounds, footpaths, and outdoor living areas
Coloured concrete including for driveways, crossovers, footpaths, outdoor entertaining areas and patios, pool surrounds
As an example, standard grey concrete typically ranges between $85 to $170 per m2, whereas exposed aggregate can range between $110 to $200+ per m2. For smaller areas, the price is usually at the higher end of the range.
All pricing is indicative. Every job is quoted individually after a site visit — no two sites are identical.

Yes — a commercial building extension in Maddington requires a building permit from the City of Gosnells before any structural concrete is poured. All concrete work on a permitted commercial scope must be executed to the licensed structural engineer's approved drawings. For commercial suspended slabs, this includes the specified concrete strength, slab thickness and any specific pour sequence requirements set by the engineer. Colacrete works precisely to those drawings — the engineer's specification governs.
-
Cavity fill involves pumping concrete into the hollow cores of concrete masonry block walls (also called besser block or CMU walls) to increase their structural strength. Filling the cavities converts hollow-core block construction into a solid mass-concrete wall with significantly greater compressive strength and lateral stability. Cavity fill is typically specified by the structural engineer where the wall loads or lateral forces on the building require a more robust wall system than hollow-core block alone would provide. It is a separate operation from the slab and is completed in its own stage.
-
Back propping is the temporary propping system installed beneath a suspended slab during and after the pour to prevent the slab from deflecting under its own wet weight before the concrete achieves sufficient strength. On the Maddington office extension, back propping was managed by others on the project — Colacrete's scope was the concrete placement and finish to the engineer's specification. On projects where back propping is within Colacrete's scope, we manage it as part of the structural concrete package.
-
For commercial office and light industrial spaces in Maddington, the concrete finish is determined by the building's end use. Internal suspended slabs are typically finished to a power-trowel finish suitable for the floor covering above. Ground floor slabs for commercial spaces are often finished to a higher standard — power-trowelled and sealed, or honed or polished where the concrete is the final floor. For external areas including driveways, hardstand and paths on commercial properties, grey concrete is the standard. Exposed aggregate or honed finishes can be specified for commercial properties where the external appearance is a consideration.
