Practical know-how for projects in Algeria
SARL ETAHG runs a quarry, a road-building fleet and a drilling rig from Djelfa and Ghardaïa, and offers its services to foreign contractors and Algerian project owners. These articles put that experience in writing: how aggregates are specified and produced, how a road is layered on each of Algeria’s terrains, when to rent rather than buy, how a site is opened in the steppe or the desert, how a well is drilled and authorized, and how subcontracting and public procurement work for a newcomer. General know-how only, written to be useful on its own.
