DILMUNIA GRAND CANAL & MARINA (DGCM)
Problem
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.
Solution
The construction of the Dilmunia canal is the object of an international Tender. The tender design for the waterproofing works has been developed by the engineering firm ARTELIA by specifying the following Maccaferri products for waterproofing & drainage functions. (1) Macline SDH 200 as the primary waterproofing layer inside the canal structure which will be retained at the upper perimeter by heat-seaming (welding) over an embedded anchor profile of ‘E’ locks and covered by 100 mm thick polymer reinforced concrete panels, (2) Macline N80.1 geotextile cushion layer intended to protect the geomembrane from damage during casting of the concrete panels, (3) Macline GCL W10 as the secondary liner designed to provide an additional watertight barrier against unexpected leakage, (4) Macdrain M120M as the drainage layer behind the concrete wall and (5) Macgrid WG 13S geogrid for ground improvement below bridge foundation structures. Maccaferri Middle East was involved in the design, supply, and construction assistance of the project.
Used Products

聚合物土工膜
塑性土工膜属于合成土工膜的一种,以片(5-8m)为数量单位供应,厚度一般 0.5 至 3 mm。 尽管制造工艺可能不同,但都具备非常小的渗透性,适用于衬里和防水应用。 比较常见的聚乙烯,得益于其耐化学性、耐用性和低成本,其他高密度质量的使用也较多。View
无纺土工布
无纺土工布是由合成纤维组成的扁平织物结构,通过针刺或热处理随意组装而成;主要用于实现分离、过滤和保护功能,并且是许多其他复合材料与土工合成材料组合的基础。 它们的质量和性能会因纤维长度、使用的聚合物、组装过程等而有所不同; 土工合成材料是最常见的一种。View
