Sands and aggregates

Sands and aggregates are among the basic natural raw materials used in construction. Thanks to their mechanical resistance, stability and wide range of possible uses, they are an indispensable part of modern construction and technical solutions.

Applications of sands and aggregates

Our portfolio includes sands and aggregates of various fractions, produced by processing the input raw material through washing, screening, blending and crushing. A wide range of particle sizes allows them to be used in a whole range of construction applications.

The materials are used in transport and residential infrastructure, in the production of concrete, precast concrete elements and blocks, mortar and asphalt mixtures, drainage systems and base layers. They are also used in the construction of sports facilities and in other specialised technical applications.

Before drying itself, the sands are washed and screened. The dried sands are filled into paper bags (25 kg) and bulk bags (1,000 kg), or are also supplied loose in silo trucks (approx. 28 t) according to the individual fractions. Various mixtures can also be prepared according to the customer’s wishes.
