Géocomposites de drainage
Drainage et filtration efficaces de l'eau
Les géocomposites de drainage sont constitués en associant, au cours de la production, une couche centrale de drainage (il peut s’agir d’un géomatelas, d’un filet ou d’un élément moulé) entre deux couches de géotextiles. Le composite peut servir à filtrer, à séparer et, parfois, à assurer d’autres fonctions telles que la protection. Malgré les multiples applications, l’objectif principal est le drainage. Pour cette raison, les performances de drainage à long terme du géocomposite doivent être bien connues (variations du fluage en compression, efficacité du filtre, etc.)

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.

MICOROSA ENVIRONMENTAL REMEDIATION PROJECT
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.

Reinforced Soil Walls and Slope Reinforcement in HUARAZ - ANCASH - Perú
The terrain had a steep slope towards the Santa River cliff and did not have an appropriate land surface for heavy transport accessibility for unloading products, making it unfeasible to construct the commercial warehouse on it. Therefore, the client needed to undertake a project involving a 19-meter retaining wall to have a larger construction area.
