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.

CHARLEROI HOSPITAL
Le ‘Grand Hôpital de Charleroi’ which has been formed by the merger of Charleroi hospitals Saint-Joseph, Sainte-Thérèse, IMTR, Notre Dame and Reine Fabiola wants to offer all their patients a completely new hospital. Together with the public authorities, they have acquired in 2012 the site ‘Viviers’. Since this site of 170000 m^2 is situated on the crossroads of the R3 and the RN90 it has perfect access for all kinds of mobility. The importance of the site authorizes landscaping with respect for the environment and the surroundings. The hospital will be one of the biggest in Belgium (approx 900 beds). VK Architects & Engineers and Reservoir A designed the site ready for the future and thus were awarded the project. The construction of the buildings is being executed by Jan De Nul/Franki. During the construction of the garage building, a drainage layer had to be installed on top of the waterproof liner. On top of the drainage layer, a further 10 cm thick layer of concrete was planned as protection to trucks driving on its surface during the construction phase of the top layers.

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.
