When compared to traditional landfill-capping systems, a geosynthetic drainage system used within a landfill surface seal offers a number of advantages, such as high-quality standards, low cost and markedly faster progress in construction.

NAUE’s geosynthetic drainage system Secudrain® R201Z WD601Z R201Z combines filtration, protection and drainage in a single product.

The use of this easy-to-install and cost-effective alternative to the typical, traditional landfill cap system is exemplified by the installation performed for the Aemilienhausen Landfill.

For the current, third construction phase, two landfill cap versions for the 110,000 m² (1,184,000 sq.ft.) landfill were being considered.

Numerous factors favoured the use of the geosynthetic drainage element. Notably, it would replace the mineral drainage layer, the protection nonwoven geotextile, and the separation and filtration nonwoven geotextile. Also, because the geosynthetic drainage system would use NAUE’s Secudrain® R201Z WD601Z R201Z and would provide the hydraulic performance of the drainage mat as well as the filter-stable separation for the recultivation soil, an emergency drainage system would not be required for this site.

With one product, a great deal of the cap’s complexity and cost could be resolved—without sacrificing any safety or long-term performance.

In light of these construction and engineering advantages and the simple installation Secudrain® enabled, the owner had no difficulty in making a decision. The geosynthetic drainage system was planned for the recultivation of the landfill surface.

Everything happened quickly from there. Construction started after the test field had been set up and the initial conformance tests had been performed on the materials. Swift and skilled installation of the BAM-approved geomembrane and the drainage mat Secudrain® R201Z WD601Z R201Z ensured that the construction was completed on time. The Unstrut-Hainich-District waste authority was fully satisfied.
