Enkadrain SL

Geocomposite sheet drain for wall and slope drainage

Groundwater can cause significant problems for civil engineering and building related projects. Water is one of the major causes of wall and slope failures and therefore the interception of groundwater and channelling away from the structure is an important consideration for designers.

Enkadrain SL is a lightweight geocomposite drain that replaces traditional gravel or sand chimney drains and is designed to collect / discharge groundwater and excess surface water behind reinforced slopes and retaining walls.




Enkadrain SL is a 2 metre wide drainage mat, consisting of a three dimensional polyester filament core with a geotextile filter bonded to both sides. The filter fabric extends approximately 0.15m beyond the edge of the drainage core to achieve a continuous filter surface.


Enkadrain SL is supplied to site in rolls that are lightweight and easy to handle. In reinforced soil slopes Enkadrain SL is laid in strips directly onto the cut batter and connected to Megaflo® panel drain at the base for collecting and discharging the water away from the structure. Having a geotextile on both sides allows Enkadrain SL to be used to intercept groundwater in reinforced soil slope and wall applications. Enkadrain SL can also be used for drainage behind low height basement walls where it is placed up against the waterproofing layer and connected into a Megaflo® panel drain at the base.
