A Force To Be Reckoned With

Aggregate manufacturers and distributors worldwide are constantly searching for more options when it comes to rock extraction. 

Winstone Aggregates’ Belmont Quarry is one of only three in the Lower Hutt area capable of manufacturing a wide range of aggregate products including greywacke, seal chip, concrete aggregates and sands.
