The machine doesn't come out for ten metres. Twenty metres is our minimum run and $980 is the minimum pour — it is on the sheet below, not saved for the invoice.

The Extrusion

Setout sheet · 1:∞

The run drawn in plan as an L with the kerbing machine crawling along it A civil setout sheet seen from above. The run is drawn as an L — a long leg and a shorter return leg. Behind the machine the extruded kerb is drawn as a continuous cured ribbon; ahead of it a magenta string line runs across the prepared ground with setout pegs at every ten metres of chainage. Crossover cut-ins appear as stop-and-start marks in the run. The frame zooms to fit the run length, from twenty metres to two hundred, while the cross-section inset in the corner holds one constant scale.

      What people say after the string comes up

      ★★★★★

      The lawn had been eating the beds for six years and I'd re-dug the edge every spring. Forty-two metres of bullnose in a morning, curved around the jacaranda exactly where the string said it would go. The mower rides the strip now and I've stopped edging.

      Deb F. · Canning Vale · 42 m bullnose, gentle curves

      ★★★★★

      I subcontract every edge I quote and I've used three mobs. Trueline are the only ones who send the metreage back with the crossovers already counted, so my quote doesn't move after the fact. Two crews, both turn up when they say.

      Marcus T. · landscaper, Baldivis · standing subcontract

      ★★★★★

      Our car park kerb had been broken for two years and every quote came back with "subject to site inspection". These blokes walked it, chalked where the limestone was, and gave us a number that didn't change. Eighty metres of barrier, done over a weekend so nobody lost a bay on a Monday.

      Asked on the verge

      The six questions we get before every run

      How long before I can mow it or drive on it?
      Stay off it for twenty-four hours — that's foot traffic, the dog and the mower wheel. Keep the reticulation off it for three days, because a sprinkler running onto green concrete washes the face and you'll see it forever. If it's a driveway edge or a crossover, give it seven days before a car goes over it. None of that costs you anything, it just takes time, and we'd rather say it now than find your ute parked on it on Tuesday.
      Why does extruded kerb have no joints?
      Because it isn't laid in pieces. The machine carries a stiff, low-slump mix, forces it through a die shaped to the profile you picked, and crawls forward laying a continuous ribbon on the ground. There is no formwork, no segment, and no joint to open up and grow weeds. We cut control joints into it afterwards where a long run needs them, but they are saw cuts in one piece of concrete, not gaps between separate ones. That is also why the setout matters so much: the machine follows the string line, so the line you approve is the line you get.
      What happens if we hit limestone or tree roots?
      We walk the line with you before the machine comes out and mark anything we can see — a limestone shelf, a big root plate, a service sitting shallow under the run. If we find something once we're stripping, we stop and show you, and you decide: shift the line, break out the obstruction, or leave the tree alone and take the kerb around it. What doesn't happen is a phone call afterwards with a different number on it. The rate a metre doesn't move; if the day changes shape we tell you before it does.
      Mower strip or bullnose — which do I want?
      A mower strip is 100 wide and 75 deep and sits flush with the lawn so the mower wheel rides straight over it and you never edge again. It doesn't hold mulch in. A bullnose is 150 × 100 with a rolled top and stands proud of the turf, so it holds a garden bed and stops the couch running into it. If the problem is edging, take the strip. If the problem is the beds losing their shape, take the bullnose. If it's both, we've done plenty of runs with a strip on the lawn face and bullnose around the beds — it's the same machine, just a die change.
      Do you do work to shire spec?
      Yes — half-batter and barrier profiles cut to the standard drawing in your local government's subdivision or engineering standards, with concrete to the AS 2876 kerb and gutter profiles. On that work the mix and the finish are specified for you, which is why the half-batter option here locks the finish to natural grey: we're not putting oxide through a kerb that's going into a road reserve. Send us the shire's drawing number with the metreage and we'll confirm we've got the die.
      How long does a sixty-metre run actually take?
      A straight sixty on bare sand is a morning — set out and string first thing, extrude by mid-morning, tidy the ends and be gone by lunch. Add a turf edge to strip and level and it's most of a day. Add crossover cut-ins and each one costs us fifteen minutes of stopping, forming an end and re-tying the string, which is exactly why they're priced separately at $85 rather than smeared into the metre rate. Tight radius work is slower again — the machine crawls through a planter circle.
