Effect of Geocomposite on Puncture Resistance of Geomembrane Liner
Damage to geomembrane during and after construction is detrimental to the integrity of the liner system in waste disposal facilities. However, the ability to define the acceptable levels of physical damage (i.e., indentation, puncture, or rupture) is directly related to the primary function of the geomembrane and the overall performance objectives for a given liner system. This paper evaluates: (1) the effectiveness of using a geocomposite layer to protect the geomembrane from physical damage during construction of overlying coarse granular drainage media; and (2) the potential damage to the geomembrane placed over a compacted clay liner (CCL) with relatively small quantity of gravel-size particles (< 3% by weight). Damages to the geomembrane for all conditions tested during this study were considered acceptable, based on the large-scale hydrostatic puncture testing observations and the multi-axial tension testing mode of failure and deformation characteristics. It was observed that the protective geocomposite layer clearly improves the survivability of the geomembrane for those instances where an overlying coarse granular material layer is necessary as part of leachate collection and drainage system.
