ABSTRACT:
A landfill system and puncture protection mat which overlies a geomembrane of the landfill system are disclosed. The puncture protection mat comprises a composite mat having a geotextile fabric layer bonded to an extruded thermoplastic rubber layer. Preferably, rubber particles formed from recycled vehicle tires are compounded with a thermoplastic in the extruded layer. With the thermoplastic rubber layer contacting the geomembrane, the bonded geotextile fabric faces upward in the landfill excavation to protect the geomembrane against puncture from rocks, sticks, metal, and other solid wastes placed in the landfill.
