Welcome to L.B. Silica Sand. We have been mining sand since the 1950's and both distribute and supply high grade Silica Sand direct from our own Quarry. Our sand has high grade Silica content and provides a consistent quality and has been used in many industries, from glass making and industrial construction, to leisure and equestrian surfaces.

Silica is another name for silicon dioxide, of which quartz is a specific latticed structure. So, silica sand is quartz that over the years, through the work of water and wind, has been broken down into tiny granules. Industrial sand is a term normally applied to high purity silica sand products with closely controlled sizing.

The aim of this work was to benchmark respirable crystalline silica (RCS) exposures in brick manufacturing and stone working sectors in Great Britain. This will contribute to a larger programme of work, which will be used to better understand the role of health surveillance in preventing the development of further cases of silicosis and chronic ...
