Foundry sand / sand for construction,
building chemistry and sport
Foundry 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 used for both mold and core manufacturing with high requirements for heat resistance. It is broadly utilized in a wide variety of other industrial and leisure activities, e.g. production of concrete products, building chemistry, (dry mortars, plasters, flooring systems, glues, fillers, etc.), blast cleaning, sports facilities (golf, beach volleyball, riding arenas), 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.
