Conclusion
Pond 4 is a tailings pond in Freital,
Germany, built in 1957 as a settling basin
for residues of the uranium ore treatment of the Wismut company. In 2015
the remediation work, consisting of an
impermeable cover system to close the
impoundment and for subsequent landscaping, started. The construction of the
cover system on top of the weak and heterogeneous tailings of Pond 4 has been
made possible by the use of geosynthetics
that provided the most economic and
feasible solution. The selected geosynthetics separated and reinforced the weak
subgrade, creating a safe and workable
surface for the installation of the cover
system. The conceptual design, the selection of the materials and the installation
phases are fully described and can be
used as reference for alternative solutions
in similar projects.
