Know your volume, thickness, strength, and access, and call the plant a few days ahead. Order a little extra, since a shortage costs far more than a small surplus.
What to have ready
Know the cubic yards you need, the strength (for example 3,000 or 4,000 psi), the slump, and any additives. Also say how the truck will reach the site and whether you need a pump.
Minimums and short load fees
Plants often set a minimum load, commonly 1 to 3 cubic yards, and charge a short load fee for small orders. For a very small job, bags may cost less.
Timing
Concrete is poured within about 90 minutes of mixing. Have forms, base, rebar, tools, and helpers ready before the truck arrives, and plan finishing before the weather turns.
Pay attention to the ticket
Check the load size, mix design, and any water added on site. Extra water weakens concrete, so keep it minimal.
Frequently asked questions
How many days ahead should I order?
Two to three days for most pours, and more in busy seasons.
What strength do I need?
Residential slabs commonly use 3,000 to 4,000 psi. Follow your plans or local advice.
Can I wash the truck out at home?
Ask the driver first. Most plants have rules about washout.
