Sustainable High-Performance Drainage for Civil Engineering & Landfill Capping

MacDrain® drainage geocomposites are engineered drainage solutions designed to replace traditional gravel and aggregate drainage layers in civil engineering, infrastructure, and landfill capping systems. Lightweight, factory-controlled, and performance-driven, MacDrain delivers reliable long-term drainage with significant environmental and construction benefits.

Smarter Drainage. Lower Carbon. Faster Installation.

MacDrain provides the same drainage capacity as thick aggregate layers—without the environmental cost.

A single truckload of MacDrain® can replace up to 150 truckloads of gravel, dramatically reducing:

  • Carbon emissions from transport

  • Quarrying and raw material extraction

  • Site traffic, installation time, and health & safety risk

This makes MacDrain an ideal solution for sustainable construction, landfill closure, and low-carbon infrastructure projects.

Engineered for Long-Term Performance

MacDrain drainage geocomposites are manufactured by laminating a high-performance drainage core between two geotextiles. Core types include mat, net, or moulded structures, while geotextiles are selected to match the application and soil conditions.

Key performance features include:

  • Reliable long-term in-plane drainage

  • Excellent compressive creep resistance

  • High filter efficiency

  • Integrated separation and protection functions

Every MacDrain product is engineered to deliver consistent, predictable performance throughout its design life.

Proven Solution for Landfill Capping

MacDrain is widely used in landfill capping and closure systems, where long-term drainage and protection are critical.

Typical landfill applications include:

  • Cap drainage layers

  • Leachate and gas condensate drainage

  • Reduction of pore water pressure

  • Protection of geomembranes

  • Replacement of thick granular drainage layers

By eliminating heavy aggregate, MacDrain reduces settlement risk and simplifies installation on steep slopes and weak subgrades commonly found in landfill environments.
