Industry Case Analysis: Geocomposite Drainage System in Geosynthetics Applications

A geocomposite drainage system is a pivotal innovation in geosynthetics, offering efficient solutions for managing groundwater and enhancing soil stability. This article delves into real-world applications of these systems, highlighting their effectiveness in various infrastructure projects.

Bluff Erosion Protection in Michigan

At a site along Lake Michigan, a geocomposite drainage system was installed to address groundwater seepage and prevent slope erosion. The system, comprising a double-sided geocomposite layer beneath coal combustion residuals, effectively intercepted groundwater, channeling it to a perforated HDPE pipe. This installation safeguarded the bluff’s integrity and mitigated surface soil saturation, promoting vegetation growth and slope stability.

Highway Infrastructure in California

In California, a highway expansion project incorporated geocomposite drainage systems to alleviate hydrostatic pressure behind retaining walls. These systems efficiently managed subsurface water, reducing moisture-related damage and enhancing the longevity of the infrastructure.

Landfill Closure in Alaska

The Homer Solid Waste Facility in Alaska utilized geocomposite drainage systems during its landfill closure project. The installation of geosynthetic clay liners and drainage systems addressed steep gradients and poor sub-surface conditions, ensuring effective leachate management and environmental protection.

Roof Garden in Singapore

A 30,000 m² roof garden in Singapore employed geocomposite drainage systems to manage water retention beneath vegetation. The lightweight drainage cells reduced structural load by 70% and decreased water retention by 80%, supporting plant health and reducing maintenance costs.

The integration of geocomposite drainage systems in various projects demonstrates their versatility and effectiveness in managing groundwater and enhancing structural stability. From coastal erosion protection to urban infrastructure, these systems offer sustainable solutions that contribute to the longevity and safety of engineering projects.
