Road edge drainage

Enkadrain Findrain^®

Water in road construction weakens the substructure and can have disastrous effects on the structure as a whole. Dynamic loads from road traffic generate a pumping effect, drawing water from the subsoil up into the road structure. Varying water table levels undermine the stability of the base course material and can cause cracking right up to the road surface. This is a case for geosynthetic drain screens which intercept water and drain it off safely into collector pipes.

The ideal is a system that is quick to install over both long and short distances. For this purpose, Enkadrain Findrain was developed for the Enkadrain product range. This drain screen can be used with a wide range of different drainpipes, draining off water quickly to the main collector, thereby securing the stability of the entire structure. Enkadrain Findrain can be dug into the sub-soil or be laid in narrow trenches.

Enkadrain Findrain is designed on the same basic tested and proven principles as other Enkadrain products, except that, with Enkadrain Findrain, the flexible three-dimensional drainage core is wholly enclosed in a heat bonded nonwoven filter. The edges are thermally sealed to prevent the inflow of silt particles. The filter is connected to the drainage core by means of thermal bonding over the entire surface or by spot welding.

Enkadrain Findrain is provided with a cord to simplify in-situ insertion of the pipe (not included) into the Findrain; product types are available to suit a range of drainpipe sizes. Enkadrain Findrain is an accepted alternative to expensive and time-consuming capillary layers (graded particle mineral or textile filters and gravel fill) for the collection of water. The mats are installed vertically into the soils to be drained. Once installed, Enkadrain Findrain collects the seepage water and transports it longitudinally to the transverse discharge pipes or outfalls. Reducing pore water pressure and allowing excess water to flow off into the drainpipe in a controlled manner will help to avoid slope and hydraulic soil collapses.

Used in roadside verge drainage, Enkadrain Findrain serves for safe water run off and prevents the mineral road sub base being weakened by capillary water buildup.

In agricultural water management, Enkadrain Findrain can be used to drain surface water run-off without the need for open ditches which would reduce the area available for cultivation, and create the ideal water-air ratio in the porous areas of the soil.

Enkadrain Findrain can be installed in narrow open trenches that are then refilled with the excavated material. A trenching machine is all that is needed for installation in many cases. Enkadrain Findrain reduces the trench width required to be excavated, and hence the volume of soil considerably over conventional drain trenches adding to the reasons justifying the use of Enkadrain Findrain.
