Manufacturing Quality

With over 30 years’ experience in the industry we have the capabilities and resources to meet all your needs. It is our policy to check and control our quality procedures and co-operate fully in any vendor assessment or inspection.

This ensures that our customers receive a reliable product and a finish of the highest quality. We also undertake regular compression tests of random batches of concrete, to ensure that all our stock line products are manufactured to the relevant Australian Standard.

We are, however, able to manufacture concrete to any specific mix requirements.
