Case Study Brief
The Logistics Challenge
Transporting 11.5 tons of GRI-GM13-certified HDPE geomembrane from Johannesburg to the MCC Copper Mine site in Tanzania required a 3,400 km road route crossing three international borders. The consignment moved through Beitbridge , Kazungula and Tunduma border posts, each requiring full customs clearance, permit verification, and inspection. Rolled geomembrane is vulnerable to puncture and UV/moisture damage in transit, so load security and weatherproofing were critical throughout the multi-day haul. Coordinated pre-clearance documentation and real-time freight tracking ensured the shipment cleared both borders without delay, arriving on schedule for the client's installation
Every consignment was matched against certificates of origin, GRI test certification, and customs declarations before departure - with document detail cross-checked line-by-line to prevent border rejections. Rolls were secured with corner protection and weatherproof wrapping to guard against transit damage across 8 days on the road, resulting in on-spec, on-time delivery with zero material loss.
