CASE HISTORY Ref: GR / CH / EP00 — Rev:03, January 13 LANDFILL CAPPING ,, , LANDFILLS Product: Geosynthetic GCL barrier MACLINE GCL W21, Geotextile Mactex BN

Problem

The problem that had to be faced in this project is the rehabil- itation of Kalampaki and Doxato landfills, not far from the city of Drama. This is a task of great importance for the wider area of the Municipality, as these landfills were the final destination of the waste after the collection. So the rehabilitation of the cell, after the deposition of waste was essential.

Solution

Geosynthetic GCL barrier MACLINE GCL W21 was used in the project of Kalabaki and Doxato landfill. The Macline rolls were placed on the final cover of the landfill cell in order to adequately seal off the waste water of the landfill. Maccaferri Hellas, considered that this was an ideal ap- plication for MACLINE GCL W21 (bentonite content 5 kg and MACLINE GCL W21 polypropylene geotextiles on both sides) as it provides suffi- cient sealing capacity and meets the require- ments according to the project design. Geotextile MACTEX BN16.1 was also used in this project in order to separate the rainwater drainage layer from the top soil cover. So the full package of this capping application, starting from the top of the waste is consisted of:

1) Sand — gravel layer (biogas layer) 2) Macline GCL W21 (waterproofing layer) 3) Sand— gravel layer (rain water drainage system) 4) Mactex BN 16.1 (separation layer) 5) Vegetative soil layer (final layer)
