The Right Blend

Aggregates of various sizes are specified to meet the criteria required for your specific job application. Aggregates add strength to the mix and we consider a variety of blending factors when mixing the concrete for your construction job.

Properties of Concrete

The principal properties of hardened concrete are:
  • Strength
  • Permeability and durability
  • Shrinkage and creep determinations
  • Response to temperature variations
Of these, compressive strength is the most important property of concrete.

How It Is Combined

We mix concrete to meet the mixing, pouring and setting properties you need for your job. For the materials to combine properly, we start with clean materials, then we carefully combine the correct quantities of each to get the right blend. Once we’ve correctly mixed your batch of concrete, we deliver it to your site for laying.
