K
knitted geotextile
A structure produced by interlooping one or more yarns, fibres, filaments or comparable elements, mainly used for reinforcement applications.

L
laid geogrid
Crosswise laid tensile elements which have a flexible junction connection (e.g. with a PVC coating) or stiff junctions in order to fulfill reinforcement tasks.
low density polyethylene (LDPE)
Thermoplastic with a lower chemical resistance and lower strength than high density polyethylene (HDPE). LDPE has a density of approx. 0.92 g/cm_ and is mainly used in agriculture applications.

M
mechanically bonded nonwoven
An arrangement of barbed needles creates by punching through loose staple fibres or filaments a three-dimensionally compact nonwoven. Mechanically bonded nonwovens have a higher elongation, are less susceptible against penetration of a stone, more resistant against puncture force and have better filter properties than e.g. thermally bonded nonwovens. Due to the three-dimensional surface structure a higher interface friction can be achieved against adjacent soils.
monofilament
One single filament manufactured of the same synthetic raw material. Monofilaments with a diameter larger than 0.1 mm are usually called rod.
multifilament
A yarn consisting of several filaments or strands.

N
natural fibre
A rottable natural material such as flax, jute or cotton, which is only used for textile products if a degradation of the product is required.
natural sodium bentonite
Naturally occurring bentonite with a high portion of sodium ions. The hydraulic conductivity of the natural sodium bentonite is in the range of < 5 x 10-11 m/s and is best suited for geosynthetic clay liners. The water absorption capacity (after 24 hours) is approx. 800 %.
needle-punched geosynthetic clay liner
An arrangement of barbed needles creates by punching through the encapsulating cover and carrier geotextiles and the bentonite core an over the entire area direction independent shear strength transmitting geosynthetic clay liner in order to increase the low internal friction angle of the bentonite and also to encapsulate the bentonite erosion safely.
needle-punched nonwoven
See mechanically bonded nonwoven
nonwoven
A geotextile in the form of a manufactured sheet of directionally or randomly orientated fibres or filaments mechanically and/or thermally or chemically bonded. Nonwovens are used for filtration,drainage, separation, packing, protection and/or erosion control applications.
