Polymeric Geomembranes
High-Performance Lining and Waterproofing Solutions
Polymeric geomembranes are advanced synthetic barriers designed for lining and waterproofing applications, offering exceptional durability and a very low permeability coefficient. Supplied in large sheets ranging from 5 to 8 meters in width and 0.5 to 3 mm in thickness, these geomembranes are highly versatile for use in environmental containment, infrastructure, and industrial projects. Thanks to their precision engineering, these geomembranes ensure reliable performance in preventing fluid migration and protecting sensitive environments.
Among the various polymers available, polyethylene is the most commonly used material due to its superior chemical resistance, durability, and cost-effectiveness. Within this category, high-density polyethylene (HDPE) stands out as the preferred choice for demanding applications, offering enhanced strength and longevity. Leveraging Maccaferri’s expertise in geosynthetics, polymeric geomembranes provide sustainable and efficient solutions for modern construction challenges.

THE ASH YARD OF THE THERMAL POWER PLANT
The Punta Catalina thermoelectric power plant is the most important electricity generator in the Dominican Republic, as it produces 30% of the country's electricity. Its source of generation is coal, and as a byproduct of this process, residue known as ASH is produced. This ash is destined for confined cells due to its high content of heavy metals, preventing environmental damage to both the subsoil and the dispersal of volatile ashes in the air.

MICOROSA ENVIRONMENTAL REMEDIATION PROJECT
Italy
The Micorosa area, designated as a National Interest Site (SIN), posed significant environmental challenges due to the presence of an industrial waste landfill. The critical environmental levels in this SIN area necessitated a permanent security intervention. The project, authorized by the Italian Ministry of the Environment, aimed to address the persistent issues through capping and physical girdling using a plastic diaphragm.

DILMUNIA GRAND CANAL & MARINA (DGCM)
Bahrain
Ithmaar Development Company is developing the reclaimed island of Dilmunia on the north-eastern coast of the island of Muharraq, Kingdom of Bahrain. The development project includes the construction of a nearly 1. 5 km leisure canal (Dilmunia Grand Canal), which will be the central attraction of the island's architectural design, including water activities, fountains, cascades, and waterfalls. Dilmunia canal is elevated few meters above the surrounding ground level, and any potential leaks may become visible and are highly undesirable. Therefore, the project foresees to waterproof the canal structure with various geosynthetic products, including several complementary watertight and drainage elements either installed inside and outside the peripheral walls.
