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
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
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.
