Materials and method · 4 December 2024
Good concrete is commissioned, not hoped for. This essay sets out a written brief, sample panels, hold points, weather call-offs and payment stages, plus the photographs this journal expects a reader to keep before anyone books a truck for the job.
Architectural concrete · 27 November 2024
A concrete stair is structure and finish in the same pour or the same precast flight. This essay treats geometry, nosings, lighting and handrails as design problems, and asks what Australian weather and bushfire rules do to an outdoor stair.
Outdoor living · 13 November 2024
A landscape retaining wall is a structure that holds soil, water and often a driveway surcharge — not a vertical finish. Height, drainage behind the wall, and whether an engineer is required matter more than the face. This briefing compares sleeper, block and poured concrete, and the roots and loads that rewrite an undrained wall.
Polished floors · 29 October 2024
Heating a slab and then polishing it is one system, not two trades who meet at handover. This piece compares hydronic and electric, cover to pipes, thermal mass from Hobart to Brisbane, cracking risk, when to polish, energy honesty, and the rugs that undo the heat.
Materials and method · 8 October 2024
A lower-carbon mix is a specification, not a colour. This essay looks at embodied carbon, the real availability of fly ash and slag in Australia, the limits of recycled aggregate on a decorative face, and the questions that separate a plant conversation from greenwash.
Outdoor living · 25 September 2024
Garden paths fail as circulation long before they fail as photographs. Trip geometry, landings, lighting and tree roots decide whether a level change is a stair or a hazard. This is a plain-language briefing on NCC ideas, permeable versus slab paths, and routes that can take a pram or a wheelchair — not legal advice.
Decorative concrete · 16 September 2024
Faux slate and printed timber ask concrete to impersonate a material it will outlast. This essay argues for honest grey and oxide in the lineage of Australian modernism, names when a stamp becomes kitsch, and sets out the few cases — access, heritage streetscape — where imitation still earns its keep.
Architectural concrete · 4 September 2024
A table, bench or planter is a small structure that has to move, drain and wear. This piece covers glass-fibre mixes, weight, frost and heat, and the honesty required when outdoor furniture is asked to look new after a decade of weather.
Materials and method · 28 August 2024
Two Australian Standards govern most house concrete, and they are not interchangeable. This essay translates AS 3600 and AS 3727.1 into questions a homeowner can ask — certificates, engineers, decorative extras versus structural minimums — without pretending a journal article is legal advice.
Outdoor living · 20 August 2024
An outdoor kitchen is a piece of climate, not a cabinet with a grill dropped in. Mass, hygiene, heat from the barbecue, and the services that feed gas, water and power all have to live with a slab that will move. Sealers that work indoors fail faster outside, and grease is a briefing item, not a surprise.
Polished floors · 5 August 2024
A shop or dining room asks a polished slab to work after closing as well as in the photograph. This piece covers chair scrape, wine and oil, trading hours, acoustics, night cleaning, heritage fitouts, and the moments when vinyl or timber is the kinder floor.
Materials and method · 31 July 2024
A decorative repair that announces itself is often worse than the original scar. This piece covers colour-match limits, crack types, spalls, overlay versus patch, and the case for documenting the damage before anyone touches the face — then leaving some of it alone.
Architectural concrete · 22 July 2024
Precast looks tidy on a factory floor and awkward on a suburban side setback. This essay walks crane access, joints, insulation and thermal mass, and says when an in-situ pour is the kinder way to meet an existing house without a fight.
Decorative concrete · 9 July 2024
An overlay is honest when the host slab can still carry load and moisture. This article explains bond, polymer overlays versus microtoppings, stencil colour, why movement joints must continue through the new face, typical delamination and mapping cracks, and when the only kind repair is to rip the slab out.
Polished floors · 18 June 2024
Polished concrete is sold as maintenance-free more often than it is explained. This piece covers what grinding does, how lithium and sodium densifiers work in principle, silica dust, pH-neutral cleaning, re-guarding, edge work and the patchy slabs that no chemistry will even out.
Outdoor living · 3 June 2024
A pool surround has to take wet feet, midday heat and the chemistry of a salt-chlorinated pool without becoming a slip or a burn. Coping is not the same job as the deck. This piece translates wet-pendulum ratings into briefing language and compares broom, exposed and honed finishes.
Decorative concrete · 21 May 2024
Seeded stone and integral aggregate age differently in Adelaide heat, Perth UV and Brisbane storms. This piece covers local basalt, granite and river pebble, surface retarders, wash timing, sealer and hot-tyre marks, and the drainage falls that AS 3727.1 expects of a residential pavement that will still look like stone in twenty years.
Materials and method · 15 May 2024
Australian ultraviolet light is a materials test, not a climate footnote. This essay distinguishes penetrating and film-forming sealers, the main polymer classes, chalking and wet-look disappointment, and why a driveway and a kitchen floor remain different recoating problems in the sun.
Architectural concrete · 8 May 2024
A wall poured in place is a drawing executed in timber, steel and vibration. This piece treats formwork as the face of the architecture, compares board-form and smooth work, and uses Canberra’s civic concrete only to show what residential scale can and cannot borrow.
Outdoor living · 17 April 2024
Salt, wind and UV punish a coastal patio faster than a catalogue image suggests. Falls, cover to steel, the junction at the house damp-proof course, and a colour that can take heat all matter more than the furniture photograph. Written for coastal Queensland, New South Wales and Western Australia.
Decorative concrete · 3 April 2024
Stamp mats, stencils and antique release can make a driveway look finished on day one and tired by year eight. This article covers joint layout versus pattern, repairability, slip under AS 4586, fading release colour, and the moment a suburban Australian stamp becomes a period piece rather than a finish.
Architectural concrete · 27 March 2024
A kitchen bench in concrete is a slab you cook on — mass, acid, heat and hygiene in one plane. This essay compares cast-in-place and precast tops, weighs the stone comparison honestly, and asks what a sealer can and cannot do when lemon, wine and a hot pan arrive.
Polished floors · 11 March 2024
Sheen on a concrete floor is a grit sequence, not a catalogue finish. This piece sets honed matte against gloss, and deals with north-glass glare, slip, trowel marks, densifiers versus topical guards, and the way maintenance quietly raises the shine you thought you had locked.
Materials and method · 6 March 2024
The first seventy-two hours decide whether a decorative surface is a finish or a repair job. This piece covers plastic shrinkage, Adelaide and western Sydney hot winds, tropical rain and alpine frost, and the simple methods that keep water in the slab.
Outdoor living · 28 February 2024
Reactive clay in Melbourne’s west, Adelaide and western Sydney will move a driveway whether the photograph looks solid or not. Thickness helps, but joints, edge beams, trees and drainage away from the house decide whether the slab stays serviceable. This is a briefing on what actually fails — and what to ask before the truck arrives.
Decorative concrete · 14 February 2024
Integral oxide, dry shake and topical stain behave differently under Australian UV. This piece explains batch consistency, sample panels, oxides versus dyes, when grey is the better brief, how Melbourne winters and Darwin wet seasons change the same pigment, and why a sealer is never a colour on its own.
Materials and method · 30 January 2024
Colour and finish begin in the batch, not at the trowel. This essay explains water-cement ratio, Australian fly ash and slag, aggregate colour, oxide loading, and how to specify a decorative mix without writing a novel the plant cannot batch.
Polished floors · 22 January 2024
A house slab can be a finished floor if you decide, before anyone trowels, whether you are polishing a new pour or grinding what a builder left. This piece covers exposure, joints, dogs, rugs, seasonal comfort and the sample grind that should happen before you commit a living room.
