We recommend a pan type mixer with a capacity of at least a 750 ltr. (one cubic yard) per batch for the preparation of the concrete.

However, for larger and solid elements [such as foundation piles or hollow core slabs of 16" height], a mixer system of at least one cubic meter (1 1/3 cubic yards) per batch is required. The location of the batching plant depends on the intended transportation system for the concrete.
