Nappe Solpac weldable membrane is a drainage geocomposite comprising a thermoformed HDPE geospacer with a symmetrical and impermeable cellular structure mated to geotextile on one side.
The edges are flat and made of a special weldable material to ensure total hermeticity.
Nappe Solpac weldable membrane is extremely versatile and can be used in a wide variety of Civil Engineering and Environmental projects such as drainage tunnels, culverts and gutters. By way of example, they can be used on their own in the topsoil in Landfill Sites to not only provide a watertight barrier, but also horizontal drainage.
Being a single solution to two challenges (drainage and waterproofing), they come with considerable advantages in terms of purchasing, logistics and installation and help save money on projects.
