Membranes For Underdrain
When building an underdrain with our nero drainage cells, membrane is a crucial part of the system, not only in ensuring that rising groundwater that enters the nero cells is clean and high quality, but also in guaranteeing that your underdrain system will run efficiently and be equipped for longevity.
When it comes to choosing a membrane for your underdrain system, we provide a selection of recommended non-woven geotextile membranes. While Non-woven membranes have less load-bearing strength than woven membranes, they provide higher levels of water infiltration and still boast the ability to block soil and sediment from passing through them.
In an underdrain application, a geotextile membrane is laid out in the soil first, before the nero cells are placed on top and connected together. This is because groundwater will rise up towards the surface, so placing a layer of membrane beneath the cells means that water has to pass through the membrane before it reaches the cells. Think of the membrane as a sediment filter in this application. This can be seen in the diagram below, where the membrane is represented by the dotted red line.
