Béton Rehamna
Quarry material processing and crushing into calibrated aggregates.
Béton Rehamna specialises in the processing and crushing of quarry materials. Through its crushing and screening plants, it turns raw rock into aggregates of various grades — sands, chippings and crushed stone — providing high-quality raw materials for concrete manufacturing and earthworks.
The first link in the chain
Founded in 2013, Béton Rehamna opens the group’s chain. Everything the other subsidiaries go on to transform — concrete, precast elements, paving — starts as crushed and screened rock.
Crushing and screening
Crushing reduces the rock extracted at the quarry; screening sorts it by size. That sorting is what produces the grades supplied: sands, chippings and crushed stone.
What these aggregates are used for
They are the raw material of concrete manufacturing, and they feed earthworks.
Product and service descriptions
Product names, grades and services are those supplied by the client. The sentences describing what they are for are written by the agency: they explain what that type of element does, without stating a dimension, weight, strength class or standard. Those characteristics remain to be supplied by the subsidiary before going live.
