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
