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.

AMUYONG
Philippines
The Provincial Engineer’s Office of Cavite has proposed the construction of a reinforced concrete wall at Brgy. Amuyong, Alfonso, Cavite for the purpose of retaining the soil below the shoulder of a portion of the municipal road, which has collapsed due to heavy rains. However, the required cut on the existing soil for the foundation of the designed reinforced concrete (RC) wall has been limited. In this, the designed RC wall was revised with a smaller wall height. To compensate the required height while recognizing the limitation of space for construction, a reinforced soil structure was needed.

CARMONA-GMA BRIDGE ABUTMENT
Philippines
An old truss-type steel bridge connecting the towns of Carmona and General Mariano Alvarez in Cavite, Philippines has undergone rehabilitation to decongest traffic in the area by constructing two new single lane bridges on both sides of the existing structure. In order to install the bored pile foundations and piers of the new bridges, a temporary passageway for heavy equipment was made by cutting about 20 meters high through an existing slope on one side of abutment. As soon as the installation of the columns and piles is finished, the removed soils have to be filled again. The backfill materials required a retaining structure in such a way that the abutment's integrity was maintained.

CDO ETERNAL GARDENS MEMORIAL PARK
Philippines
Eternal Gardens is a leading developer of first-class memorial parks and provider of memorial care products and services. The latest addition to their ten memorial parks located throughout the Philippines is the Greenhills Memorial Park in Cagayan de Oro City, Misamis Oriental. In one section of the memorial park, a six-meter high retaining wall had collapsed after a series of heavy rainfall. The collapsed and damaged section of the existing wall made of hollow blocks with reinforced concrete columns stretched for some 40 meters. Immediate rehabilitation of failed section was required to ensure smooth operation in the memorial park.
