After reaching the maximum capacity of the landfill, waste has to be isolated to prevent environmental pollution. After isolating, the aim is to create a ‘natural’ look of the landfill. To have it fit in the landscape, the capping will be covered with 1 meter top soil and seeded with grass. Capping of a landfill is an expensive job. Considering that capping must be re-done as soon as the capping system has reached its full life-time, authorities will immediately start saving a yearly amount of money to be able to finance future re-capping. When the life-time expectancy of the capping system is increased, less annual savings will be required.
THE ENKA SOLUTION
Installation of a high quality capping system; all components having a life-time-expectancy of 100 years minimum!
- Double barrier layer: polymer modified sand/bentonite layer, secure welded structured 2 mm HDPE liner
- Drainage layer: EnkaDrain ZB 350
INSTALLATION BENEFITS & RESULTS
EnkaDrain ZB 350 is produced and audited according to the German BAM (Bundesanstalt für Materialforschung und -prüfung) regulations, in order to produce a drainage composite with not only a 100 years life expectancy of the product itself but also of its functionality.
With the use of EnkaDrain ZB 350, savings for a potential future capping can be spread over a period of 100 years.
