TECHDRAIN Mines

Mines

Located over the containment liner in caps and closures, drainage geocomposites are used to avoid hydraulic pressure buildup in topsoils
Leachate collection layer:
Geocomposite drains offer the most reliable system to avoid the accumulation of leachate over the base liner while keeping its structure unsaturated
Leak detection layer:
Geonet and geocomposite drains are placed in between containment layers to create a void space through which leaking fluids can be detected and displaced outwards

Formed by a triplanar HDPE geonet thermally bonded over one or both sides to nonwoven PP geotextiles

Contributions

-Improves the drainage capacity or completely replaces the natural drainage layer
-Homogeneous drainage solution that follows strict quality control procedures
-Simple and aesthetic design that harmonically complements other geosynthetic systems
-Lightweight and flexible composition
-Highly robust and resilient, able to withstand the loads applied during installation
-Chemically inert and imperishable
-Fast, easy and reliable installation, does not require heavy machinery or qualified staff
-Outstanding transportation capacity
-Easy to store and protected against external agents
-Low carbon footprint

Features

-Extremely high transmissivity
-Extremely low core compressibility
-Stable transmissivity over the long term in accordance with GRI GC13 Specification
-Suitable for installation over steep slopes
-Customizable geotextiles
-Under ISO and ASTM Standards
-Rolls up to 4-m wide and customizable length

Why are the INTERMAS geocomposites the best drainage solution for mining?

They provide excellent compressive strength and durability which makes them especially suitable for applications with high loads (PADS leaching PADS  and settling ponds) as well as excellent protection of waterproofing systems (CBR conedrop, etc ...).
They have an optimal creep behavior for mining applications which guarantees a proper performance of the product throughout the design life of the jobsite.
They have excellent resistance to oxidation and microorganisms. The structure of our geocomposites has been specially designed to ensure excellent steadily hydraulic flow even under severe conditions.
They have CE marking and have been tested in external labs with GAI-LAP certification having numerous and successful references.
