How much is a cubic meter of ready mix concrete

Domestic bagged ready mix concrete you can buy from merchants tends to be more expensive than site mixes we supply in ready mix concrete. Typically bagged ready mix concretes range from £65 - £85 M3 . We cannot offer a guide on site mixes as this depends on your region and the type of mixes you require and we supply performance concretes and bespoke mixes that have proven added qualities, sustainable properties and have been thoroughly tested compared to the bagged versions you might buy.

Disadvantages of ready mix concrete

  • Requires effective transportation system from our batching plants which is why we always recommend delivery from our trucks
  • Set curing times concrete should be used with 210 minutes of leaving our plant so factoring in traffic jams etc is why we have over 60 plants across the UK and team of trucks and dispatch staff on hand to support you in getting your delivery there on time and ready to be offloaded.
  • Manual offloading can be labour intensive which is why using a pump is optimum in most scenarios.
