Drainage Geocomposites
Efficient water drainage and filtration
Drainage composites play a pivotal role in diverse applications, spanning civil engineering, planar installations, roofing, and landfill projects. These composites, formed by combining a drainage core layer (such as a mat, net, or moulded element) with one or two layers of geotextiles or geomembranes during production, serve functions like filtering, separation, and, in some cases, additional features such as protection.
The primary and key function of drainage composites is drainage, therefore it’s mandatory to determine the variation of such performance in time as a result of the surrounding conditions.
Among the key factors, considerations about compressive creep reduction, flow rate variations, and filter efficiency are critical to ensure the sustained effectiveness of these composites.
Given the extensive range of applications for drainage composites, specialized product families have been developed to meet specific needs and provide optimal performance in different scenarios.
TerraDrain™ for Sports Fields
Tailored for sports field applications.
Specifically designed to address drainage requirements associated with athletic surfaces.
MacDrain™ W for High Flow Rates and heavy load conditions
Engineered to withstand and effectively manage high flow rates.
Suitable for applications where rapid drainage is a priority.
MacDrain™ M for High Flow Rates and medium load conditions
Primarily designed to handle high compression loads.
Tailored for particular applications, providing unique advantages.
These specialized product families highlight the versatility and adaptability of drainage composites, ensuring they meet the specific demands of various projects. Whether utilized in civil engineering, planar installations, roofing, landfill projects, or sports fields, MacDrain™ W and M excel in high-flow rate scenarios. Additionally, the MacDrain™ N family provides a tailored solution, designed specifically to withstand extreme compression loads. These tailored product families aim to deliver optimal performance and the best possible user experience in their respective applications.

CHANNELIZED STREAM TECHNIQUE FOR RIVER PRESERVATION AT THE RGE CIB
Indonesia
RGE Cibitung Warehouse, part of the Royal Golden Eagle (RGE) Group, is a modern logistics facility located in Cibitung, Bekasi, Indonesia. During the planning process, this project faced major challenges related to the presence of a river next to it. This river is a tributary of the Cibuntu River, which is experiencing bed erosion, causing the river to widen from 6 meters to 8-10 meters. This scouring occurs because there is no adequate protection on the river banks. This condition has the potential to endanger the structure of the warehouse being built because it can cause further erosion and threaten the building's foundation. To overcome this problem, careful technical and environmental engineering measures must be taken. One of the main efforts is to return the river to its original dimensions to ensure the stability of the surrounding environment. This work involves strengthening river banks with erosion-resistant materials and creating safety structures such as revetments or earth retainers to reduce the rate of erosion naturally.

CONSTRUCTION OF SPILLWAY FACILITIES FOR PONDOK RANGGON RESERVOIR
Indonesia
Some parts of the Embung Pondok Ranggon slopes have experienced erosion due to heavy rainfall, uncontrolled water flow, and a lack of protective vegetation. This condition threatens the stability of the reservoir, increases the risk of landslides, and reduces storage capacity due to sediment accumulation. If left unaddressed, the reservoir will lose its function as a flood control system, irrigation water storage, and groundwater conservation. Revitalization is needed to strengthen the reservoir structure, reduce sedimentation, and maintain water quality. Additionally, this improvement will enhance the area's aesthetics, which serves as a Green Open Space (GOS), creating a safer, more comfortable, and sustainable environment for the surrounding community.

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.
