Soil Washing

Soil washing is a process whereby inert construction waste can be processed into clean, washed and graded aggregates for use back within the construction and manufacturing process.

The washing process uses high pressure water jetting, robust scrubbing and vibrating decks to separate sand and soils from natural stone and rock contained in the feedstock material.

Washed stones are sized and stockpiled to suite site or market requirements.

Two grades of sand can be separated from the fines suspended in the water used in the washing process.

Soils are removed from the water using flocculent thickeners and mechanical plate presses.

75% of the water used is recycled and put back into the jetting system at the front end of the operation.
