Enkadrain CK is a multi-functional mat designed for use as both drainage layer and lost shuttering between rock surfaces, bentonite walls, existing structures and new structure walls.

The Enkadrain CK product range comprises a number of different product types whose cavity-rich core is attached to a nonwoven filter on one side and a concrete or shotcrete tight PVC layer preventing cement slurry entering the core. Both, the PVC layer and the nonwoven filter extend 10 cm to one side of the core in opposite direction. This ensures that the joint is covered when lanes of Enkadrain CK are laid adjacent to one another.

Enkadrain CK can be used for drainage at great depths. These products are so flexible they can be adapted to the most complex geometries. Using Enkadrain CK means you can apply concrete direct without any loss of space. In many cases, it serves as lost shuttering, replacing one shuttering.



All Enkadrain CK products are quick and easy to use, and can be attached to the sheeting using construction adhesive or PVC discs nailed to the rock. Enkadrain CK is elastic, which means it can also be used as a flexible separation layer between adjacent buildings, reducing soil-borne noise and vibration considerably and acting as a load separator. This can be particularly useful in railway construction projects.

The products' drainage capacity, flexibility and filter performance are such that when used horizontally, Enkadrain CK acts as a water relief and anti-capillary layer between sub-grade and base slab. In smaller projects where the demands on drainage capacity and the membrane seal are less important, Enkadrain CKL 10L can serve as the ideal alternative to Enkadrain CK.

Tailor-made Enkadrain CK product types are available for special applications such as in tunneling.
