Landfill
TERRAM Geosynthetics provides the critical properties for geosynthetics used in landfill engineering; Robustness to withstand installation and service life. Puncture resistance to protect the liner from puncture. Extensibility to adapt to point loads without failing. Chemical resistance for sustained contact with leachate. UV resistance for the period before the product is covered by waste.
Side slopes
Products
Application Function
The design requirements of a cell side slope are principally that the impermeable membrane must be protected from mechanical damage and that leachate must be conveyed to a collection system for treatment or dispersal. In some instances, site conditions may give rise to the need for pore-water pressure relief beneath the membrane.
Side-slope applications for TERRAM geosynthetics
TERRAM robust geotextiles are used both above and below impermeable liners to protect them from puncture. High puncture resistance ensures that the waste bearing down on a stone drainage layer causes no distress in the liner.
TERRAM geocomposite drains are used beneath liners to relieve pore water and above liners to collect and convey leachate. Drainage can be incorporated within the protection layer to provide the drainage function.
Interface friction needs to be considered when installing geosynthetics on side slopes as in-plane shear forces are generated as the fill is gradually raised within the cell and it settles. Factory bonding of geosynthetics layers has distinct benefits over loosely-laying individual components on site. On-site jointing of adjacent rolls is particularly important to ensure drainage continuity and to avoid distress.
