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.
