Filtering sand / sand for construction and building chemistry
Filtering sand from Provodín is a processed raw material with standardized chemical and physical features. It is typical for high level of chemical purity with SiO2 content approx. 99%.
The sand is very well suitable for the use in water treatment plants, swimming pool filtration, drainage systems, etc., as well as for other industrial and leisure purposes (concrete products, building chemistry, blast cleaning, gardening, etc.
The final product is a result of a sophisticated manufacturing procedure from blasting and crushing of a solid sandstone rock to further multi-step processing (washing, screening, classification by conterflow separators) and, if required, drying. The sand can be supplied in both wet and dried form, in bulk or packed in 25kg bags. Both truck and rail deliveries are available.
