DRAINTUBE CONDUCTIVE – Leak Detection and Drainage in One

DRAINTUBE™ is a range of multi-linear drainage geocomposites, designed for high performance drainage applications in the civil construction, landfill and mining sectors. DRAINTUBE® CONDUCTIVE is part of this range and adds the extra benefit of electrical leak detection in addition to the drainage, filtration and mechanical protection offered by DRAINTUBE™.

DRAINTUBE® CONDUCTIVE adds a conductive grid made of stainless-steel wires woven on a 50 mm spaced nylon fibre mesh. The addition of the conductive grid in this product allows for leak detection by geo-electrical methods, protects the geomembrane from being punctured, and drains any leakage during operation.

There are multiple uses for DRAINTUBE® CONDUCTIVE. These include:

• Protecting groundwater from infiltration of mine tailings and process water

• Confinement systems installed on a natural soil later with low or variable conductivity (e.g. layers of dry material).

• Checking for leaks during construction and draining any leachate leakage during operation

One Product for Many Needs

DRAINTUBE® CONDUCTIVE has the benefits of both a drainage geocomposite and a conductive grid, incorporating drainage, filtration, mechanical protection and electrical conductivity features all into a single product requiring a single installation. The standard requirements of DRAINTUBE® installation apply, including procedures for overlapping panels and the connection of mini-drains.

Quick and Easy Installation

The system is quick and easy to install and offers significant cost reductions, improved performance and a reduced environmental impact as a replacement of granular layers. The installation of a double geomembrane liner and a geoelectric leak detection campaign increases the safety of the entire system with respect to environmental risks. DRAINTUBE® CONDUCTIVE will remain functional for many years even in humid environments, a great alternative to other products (e.g. aluminium or other conductive materials) which degrade within a few months after installation.

Benefits of DRAINTUBE® CONDUCTIVE

• Geocomposite that provides four functions:

• Mechanical protection

• Filtration

• Drainage

• Leak detection

• Homogeneous diffusion of electric current under the geomembrane

• Compatible with geo-electrical leak location surveys:

• Water Puddle and Arc test methods for exposed geomembranes

• Dipole test method for covered geomembranes

• Easy installation with a single product to unroll

• Cost-effective and environmentally friendly solution as it replaces granular layers
