Landfill trenches with geocomposites
June 1st, 2022
Q: I am wondering if you know of or can point me in the right direction in regard to determining viability of leachate disposal via spraying back onto the active face of a landfill. I have a landfill that has a few issues, and while, from a practical sense, we have had some success with […]
Multi-linear drainage geocomposites for railways
June 1st, 2022
FIGURE 1 Multi-linear drainage geocomposite under railway embankment In civil engineering, drainage systems are traditionally made with granular material layers and perforated collector pipes. The use of drainage geocomposites became more common 30 years ago with the development of products that met the specific requirements of each application. Moreover, the geocomposite is cheaper than the […]
Layfield introduces HydraNet geonets/geocomposites
April 7th, 2022
Layfield introduces HydraNet geonets/composites, described as cost-effective and environmentally conscious alternatives to aggregate drains. Layfield Group Ltd. has launched HydraNet, a premium line of geonets and geocomposites. HydraNet is constructed from either two strands (biplanar) or three strands (triplanar) of high-density polyethylene (HDPE) extruded into a net-like sheet. Geonets are used to provide channelized flow […]
