Ready-Mix Concrete

Leading service providers to the construction industry

Denron is a leading supplier of ready-mix concrete to the industrial, commercial, residential, agricultural and municipal sectors in the Garden Route. With our own automated ready-mix batching plants in Knysna, and Plettenberg Bay we cover the Garden Route (stretching from Tsitsikamma to Plettenberg Bay, Knysna, Sedgefield and Wildernis.

Denron is dedicated to providing quality concrete products, with complete customer satisfaction and personal service.

“Quality concrete” as a structural building material depends largely on the mix design, the quality of your raw materials, the production and the delivery methods used. Our concrete mix designs, quality and strength are compliant with SANS 10100-2:2014, SABS0100-1 and SARMA standards and specifications.

At Denron, we recognise our clients’ need to have guaranteed supply of quality concrete, delivered timeously and receiving trustworthy laboratory test results. We do our very best to ensure that our clients get exactly that.

Denron has its own quarries in Plettenberg Bay, Knysna, and Sedgefield and can therefore ensure that quality raw materials are always used in our batching process. Thus by controlling the quality of our raw materials, never ceasing to optimise our mix designs, and by using quality equipment you can only expect the best quality concrete delivered.
