Industrial rocks

K Investments is a company specialising in the import and export of industrial rocks and solid fuels with extensive experience in raw material trading.

Import and export of industrial rocks

As a company that has been distributing raw materials for more than 30 years, we have extensive knowledge in the field of wholesale industrial rock. We take an individual and comprehensive approach to each customer, offering personalised solutions that best suit the requirements of their business. We inspect every aspect of our services – so that we can provide our clients with the highest level of service and meet their every expectation, even the highest.

Our services include the wholesale of bauxite, limestone and the wholesale of basalt, as well as their import and export.

In addition to the top quality of the raw materials we distribute, we also offer customers fast and, above all, safe transport. The export of industrial rocks itself, on the other hand, is carried out by water (river and sea) and land (road and rail), which guarantees their delivery at the place and time you expect.

We have long-standing contracts and exclusive agreements with major industrial rock producers from all over the world, including Poland. This allows us to offer our customers attractive raw material selling prices and prompt delivery - also on a "just in time" basis. We only work with the best, which is why we can guarantee the highest quality of the products we supply.
