All of the above mentioned allowed us to significantly increase the production volumes and sales of products during this period.

During the last 10 years, in the construction of road foundations, the European Union has completely switched from fractionated crushed stone to unbound mixtures. With the Benninghoven equipment we can produce asphalt mixtures according to any recipe, moreover, one of the components of these mixtures is washed limestone sand, which is much cheaper than crushed stone.
