Current figures show that the demand for aggregate equates to eight tonnes for every person annually. To meet this requirement, a readily available supply of aggregate is essential.
Data retrieved from 50 years of geological information and site research means that Winstone Aggregates can forecast and schedule supply in excess of 30 years.
With the largest network of quarries and sand plants in New Zealand, we are able to plan distribution efficiently and have the ability to supply large volumes of stock at short notice.
Working with a natural resource, we are constantly challenged to minimise variances in product.
Our quality control processes include extensive testing at our own IANZ Certified laboratories in Auckland, Hamilton, Wellington and Canterbury. We are able to test and monitor product so that any significant variances are addressed within 24 hours.
