The engineered turf cover is a relatively new landfill capping technology. It has been increasingly used in the last decade for closure of municipal and industrial solid waste landfills and other waste disposal facilities. Compared to traditional soil-geosynthetic covers, the engineered turf cover does not have protective and vegetative soil layers; therefore, there is no veneer slope failure that involves the soil mass and underlying geosynthetic components. The engineered turf cover consists of structured geomembrane and engineered turf, both of which are flexible geosynthetic materials and can tolerate tension and elongation due to differential settlement. Geotechnical performance of the engineered turf cover is discussed in the paper. Wind tunnel tests were conducted to investigate wind performance of the engineered turf cover. An example calculation is provided to illustrate the procedure of using the pressure coefficients obtained from the wind tunnel tests to estimate the factor of safety of the engineered turf cover against initiation of wind uplift.
