10-20 mm crushed stone is produced from diabase at the Sartauskoye-8 deposit (Aktobe region). The cubical grain shape and M1400 strength class make this fraction a versatile, in-demand aggregate for most commercial applications — from asphalt concrete mixes to drainage systems.
Used in concrete grades M300-M500 and precast products, road construction, foundation work, manufacturing of premium paving slabs and landscape projects. F300 frost resistance and minimal abrasion (I-1) guarantee long-term durability of structures and bases under the harsh continental climate of Kazakhstan.
Logistics: the deposit’s proximity to Bershogyr station enables fast wagon loading. We ship into customer’s wagons or deliver to your station anywhere in Kazakhstan. Submit a request — our managers will confirm volumes and provide a delivered cost calculation.

Frequently asked questions
How much does 10-20 mm crushed stone (diabase) cost?
Retail price of 10-20 mm crushed stone (diabase) at HKC is 4,900 KZT/t including VAT, with wagon loading at Bershogyr station included. Wholesale terms are available for large buyers — contact our manager.
What is the difference between cubic-shaped and ordinary crushed stone?
Cubical grain shape (flakiness ≤10%) produces tighter packing. In concrete this means lower cement consumption for the same strength grade — up to 10-15% saving. In asphalt, cubical aggregate delivers better bonding with bitumen and a longer pavement life.
What is the minimum order?
Minimum order — 1 rail wagon (about 69 tonnes). For large projects we assemble trains of any size. Truck shipping is not offered — rail only.
Which destinations do you serve?
We ship by rail across Kazakhstan from our siding at Bershogyr station (Shalkar district). Primary destinations: Atyrau, Mangystau (Aktau), Aktobe, Uralsk and other regions. Delivered prices on request.
Which documents are provided?
Every batch ships with a quality passport, test reports and conformity certificate per GOST 8267-93. Tender packs include a radiological report.
