DALTEX aggregates - A unique process

We follow a highly tuned and carefully mastered method to produce our high quality aggregates. It is this care and precision that makes DALTEX aggregates the industry standard for quality and consistency.

The cleanest aggregate

Firstly materials are washed to remove surface dust and grit through one of two tumble washers, then left to drain before passing through one of two rotary drying plants.

Perfectly dry aggregate

The aggregates are heated in the driers and tumbled to ensure grit and dust is removed from the stones prior to screening.

Fast and efficient bagging

Screening is vital to ensure the product is consistently graded and clean. To prevent any contamination, the product is quickly bagged on one of our four automated packing lines.

Palletised and protected

The product is palleted and shrinkwrapped using a robotic hooder. Strong packaging ensures DALTEX aggregates arrive in pristine condition and can be stored outside ready for use.

Product runs of 100 to 300 tonnes ensure a consistent and reliable material output and our stock holding of 2000-3000 tonnes means we are able to deliver to factory, yard or site in full loads or by pallet, by courier next day if required.
