Landfill

Landfill

Critical properties required in landfill engineering are provided by TERRAM Geosynthetics; 

i) Robustness to withstand installation and service life.

ii) Puncture resistance to protect the liner from puncture. 

iii) Extensibility to adapt to point loads without failing. 

iv) Chemical resistance for sustained contact with leachate. 

v) UV resistance for the period before the product is covered by waste.

Basal areas


Basal applications for TERRAM geosynthetics

The area subjected to the greatest surcharge loading and where hazardous leachates collect is the area at the base of a landfill cell.

This area presents the deepest transition point between the landfill cell and the surrounding strata and the most challenging location to rectify if there is a failure. Therefore it is the most critical areas in terms of the design.

TERRAM solutions form an integral part of the required solution in this key area of the landfill cell. Whether a geotextile or a geocomposite is required, our robust solutions are specifically designed to relate as closely as possible to the key properties of adjacent materials (such as the elongation of the geomembrane).
