Ordering ready-mix concrete in Bali: questions we get

Concrete batched at a plant to a controlled recipe — cement, aggregates, water and admixtures weighed by machine — and delivered in a mixer truck. Compared with site mixing you get a consistent grade, no storage of materials on site and a large pour finished in hours.

The one on the structural drawing. As a guide: K-225 for ground floors and light foundations, K-250 for slabs and columns of small houses, K-300 for villa frames and suspended slabs, K-350 for pools and tanks. See our grades page for details.

Slump measures how fluid the mix is. 10 ± 2 cm is typical for placing with vibrators, 12 ± 2 cm for pumping. Never add water on site; order a plasticiser if you need a more fluid mix.

Standards allow about 90 minutes from batching to the end of discharge, less in heat. That is why distance from the plant and a ready crew matter — the truck should not wait at the gate.

Most plants in Bali set about one truck load as the minimum; smaller volumes are possible with a part-load surcharge. Ask when you request the quote.

Standard mixers in Bali carry about 6–7 m³; minimix trucks for narrow access around 3 m³.

When the truck cannot discharge directly into the formwork: upper floors, pools, sites behind narrow lanes, large slabs that must be poured fast. The pump is a separate service; tell us the distance and height from where the truck can stand.

Often yes — with a minimix truck or a pump line from the main road. Send a photo of the entrance and the road width, and we will tell you what fits.

Light rain is manageable with covers; heavy rain dilutes the surface and must be avoided. In the rainy season plan pours for the morning and keep plastic sheeting ready. If the weather turns, we reschedule rather than pour into a storm.

A few days ahead for a standard pour; large volumes and pumped pours earlier. We confirm the slot in writing.

Ask for a slump test at the site and test cubes for each pour, with results at 7 and 28 days. We will state exactly what is included in your quote.

Formwork closed and oiled, reinforcement checked and chairs in place, a clear path for the truck or the pump, enough workers and vibrators for the volume, water and covers for curing. Have someone authorised to sign the delivery note.

Payment terms are stated in the quote — deposit, payment on delivery or agreed credit for regular customers. Company and private invoices are available.

The tax basis is stated on every quote; compare suppliers on the same basis.

Yes. Every customer's volumes, prices and project details stay between you and AVC and are not shared with anyone.
