Tahe Gold – Delgo Gold Mine
In Sudan's northern desert, the lining material selected for the gold mining operation in the Delgo region was a white-surfaced HDPE geomembrane. The technical rationale for this choice was clear: in the desert climate, standard black membrane surfaces can reach temperatures exceeding 70 °C at midday, whereas the white surface, thanks to its co-extruded top layer, reflects a significant portion of solar radiation, significantly reducing the membrane surface temperature…

Endeavour – Hounde Gold Mine
Being part of the expansion plan of the same facility during a field operation spanning three years across four distinct phases required adapting to site dynamics while maintaining the same quality standard for each phase. Based on the base containment system established in Phase 1, new cells adjacent to existing cells were integrated in subsequent phases, with tie-in details executed during phase transitions…

Roxgold – Yaramoko Project
The Yaramoko site in Burkina Faso's arid savanna belt required a distinct approach regarding the containment design of the waste storage facility. Since the distinct dry and rainy seasons throughout the year brought the thermal expansion/contraction behavior of the HDPE geomembrane to the forefront, the panel deployment pattern was established by taking into account diurnal temperature differences and thermal stress zones. After the subgrade preparation was completed…

BP – Sanqachal Project
The decisive factor in this work carried out for an international petroleum operator was the end-user quality specifications. Site acceptance criteria mandated compliance with international oil and gas industry standards at every stage, from geomembrane sheet thickness tolerance to the non-destructive testing rate on weld seams, and from welding operator certification to daily QA/QC reporting. At the terminal site on the Caspian coast, hydrocarbon-contacted waste and…

Iamgold – Essakane Project
At the Essakane site, which has become one of the longest-running operations in the company's West African portfolio with a site presence spanning nearly five years, the geosynthetic lining systems for the waste storage facility and process ponds were executed in close coordination with the Iamgold engineering team. QA/QC meetings conducted on a weekly basis with the employer's site control engineers ensured that panel layout plans on the site topography...

Kinross – Tasiast Starter Cell Project
The start-up cell of the heap leach operation was a critical path item that directly determined the commissioning schedule of the site. The timely completion of the leach pad lining system was mandatory for the ore stacking operation to start on the planned date, and accordingly, the application plan was accelerated to a tempo close to a two-shift basis, day and night. Prior to the HDPE geomembrane deployment, the lower surface was compacted clay liner…

Sare İnşaat – Çiğli Project
This application carried out on the northern axis of Izmir was one of the early examples of lining work performed for an industrial waste storage facility. Due to Cigli's location close to the coast, the high groundwater level and seasonal weather variability required keeping the time window between subgrade preparation and membrane laying tight. Carried out in coordination with the main contractor Sare Insaat…

Özdoğu İnşaat – Tepeova Copper Mine
Unlike a conventional liner deployment job, the Tepeova project was structured with an integrated delivery model where supply and installation were executed under a single roof. While the employer coordinated the site in the capacity of main contractor, the smooth progression of the geomembrane and drainage geocomposite supply chain and installation discipline without waiting for one another was decisive for maintaining the schedule. The waste generated in copper mining and…

Elmalı Greenhouse Ponds Project
Industrial-scale greenhouse complexes require multiple ponds with different functions, ranging from irrigation water reserves to fertilizer solution collection lines. The ponds designed in this project were positioned for the storage of water used in the greenhouse and for directing drainage water to recovery lines, therefore the containment system was designed to be resistant to both fresh water and nutrient solution contact…

Cetco – Alpagut Pond Project
Liner selection in water storage structures for irrigation purposes is the critical decision determining the long-term performance of the project. In this project, a bentonite-based composite liner (GCL — Geosynthetic Clay Liner) was preferred instead of conventional HDPE; the self-healing structure of bentonite upon contact with water by hydrating provides natural tolerance against minor punctures and perforations…
