Modern engineered landfill systems are designed to safely isolate waste from the surrounding environment through multiple engineered containment layers. Geosynthetics form the core of these systems by providing containment, protection, drainage, filtration, and reinforcement to ensure long-term environmental safety and structural performance.

Engineered landfill systems are designed to isolate waste from the surrounding environment through a combination of containment, protection, drainage, filtration and reinforcement layers. Geosynthetics form the working core of each of these engineered components, ensuring long-term environmental safety and operational performance.
Landfills are broadly classified into Municipal Solid Waste (MSW) Landfills and Hazardous Waste Landfills, depending on the type of waste being disposed, each designed with an appropriate level of containment to meet environmental regulations and project-specific requirements. Municipal Solid Waste landfills generally utilize a single composite liner system comprising a geomembrane over a compacted clay or geosynthetic clay liner, supported by geotextile protection layers and an efficient leachate collection system, while Hazardous Waste landfills require advanced containment systems incorporating double or triple composite liners, primary and secondary barrier systems, leak detection layers and high-performance protection geotextiles.
TechFab offers a comprehensive range of geosynthetic solutions for engineered landfill systems, including protection geotextiles, drainage composites, reinforcement geogrids and filtration geotextiles. Our engineering team provides technical assistance, product optimization and application support to deliver durable and sustainable landfill solutions.

A TechFab Engineered Landfill System is a geosynthetic-based containment system that safely isolates municipal and hazardous wastes through engineered barrier, protection, drainage, filtration and reinforcement layers to achieve long-term environmental protection.
TechFab geosynthetic solutions are suitable for Municipal Solid Waste (MSW) Landfills and Hazardous Waste Landfills, providing complete containment, drainage, filtration and reinforcement solutions.
TechGeo Nonwoven Geotextile is a needle-punched polypropylene geotextile used as a protective cushioning layer above and below geomembranes to prevent puncture and extend liner life.
TechGeo Heavy Nonwoven Geotextile is a high-mass protection geotextile designed for landfill applications where increased puncture resistance and durability are required.
TechGeo PP Woven Geotextile is an engineered woven polypropylene geotextile used for filtration and separation within landfill leachate collection systems.
TechDrain Drainage Composite is a geonet drainage system with geotextile filters that efficiently collects leachate and facilitates landfill gas movement while maintaining high flow capacity.
TechGrid PET and PP Geogrids are reinforcement geosynthetics used to strengthen landfill perimeter bunds, containment embankments and steep waste slopes.
TechFab Steel Gabions are rock-filled wire mesh units used for erosion protection, toe protection of landfill embankments and drainage channel protection.
TechFab Engineered Landfill Systems are suitable for municipal solid waste landfills, hazardous waste disposal facilities, industrial waste management projects, mining waste containment systems and other engineered environmental applications.
