-
Recommended application
Field drainage
For drainage on plots where the depth of groundwater deposition is less than the drainage norm, i.e. land plots for which, due to high groundwater levels, the topsoil is unable to drain excess moisture in the spring period, as well as due to high groundwater levels, underground engineering structures, roads, etc. are damaged.
Drainage system EVODRAIN FLEX R2 type pipes are applicable for installations in:
In agriculture, forestry, in parks, squares and peat fields
Temporary and permanent drainage at construction sites
Stadiums and sport complexes
Pavements, pedestrian and bicycle paths
Landfills (liquid and biogas collection)
Road construction - with and without traffic load

Every EVODRAIN FLEX pipe coil is equipped with a double sleeve, which provides easy connection of pipes.
It is possible to achieve a hermetic seal with a pressure rating of ≥0,5 bar (for the coupling area) by adding a rubber sealing ring. Oil-resistant¹ sealing rings are available on order, compliant with the requirements of EN 681-2 p.5.10.¹ Compliance is determined by the "Volume change in oil" test according to ISO 1817.
