Know your delivery: drum mix vs on-site mix
Ordering concrete and not sure which delivery method suits your job? Here's the difference, straight up.
Drum mixers arrive pre-batched and ready to pour, full 8m3 loads only, and the mix can't be changed once it's made. Great for commercial jobs with fast discharge needs and someone on-site who knows their exact quantities.
Volumetric mixers do it differently. Concrete gets mixed on-site to the exact amount you need, so there's no waste and no overordering. The operator can stop and start, or adjust the mix if weather or plans change halfway through.
Not sure your job fits neatly into one or the other? We often combine both, say two drum loads for the bulk of an 18-19m3 pour, then a volumetric top-up for the last few m3 to get it spot on.
Which method sounds right for your next pour, drum, volumetric, or a bit of both?
