Geotextile product programme

LIO filter plastica (non-woven textile) is made using the latest needle-punched polyester fibre technology. This technology, the raw materials used and the automatic production process enable quality distribution of fibres and the manufacturing of a large number of product types varying in weight, physical, mechanical and hydraulic characteristics.

Other features:

  • Chemical and bacteriological impact resistance
  • Good hydraulic characteristics (porosity, filtration and permeability)
  • UV stability
  • High and low temperature stability
  • Mechanical binding option

Basic functions:

  • Creating a separating layer (to prevent two layers with different geomechanical features from mixing even under increased static loads)
  • Filtration effect (to prevent the penetration of fine grains (larger than 50-80 microns) from silty water or clay base into the buffer layer)
  • Drainage effect (water absorption, steady discharge and capillary water prevention)
  • Reinforcing effect (soil tension takeover and distribution over larger surface areas).



In road building, for addressing the issues of low or insufficient base soil capacity under increased humidity conditions or adverse geomechanical features of the base soil. Used for building low-cost, durable farm roads without humus removal and shoulder-building.

In the building and rehabilitation of railways, filter plastica is set up between the ballast and formation level. In that way, the lower layer materials are separated, their mixing is prevented, water drainage is enabled, and filter plastic partially takes over the upper layer tension and redistributes vertical tensions to a larger surface area. It also serves as mechanical protection for hydro-insulation foil in tunnel building.

In high-rise construction, landslide drainage and soil drainage behind retaining walls. In foundation-building on surfaces of low bearing strength and high compactability, the buffer layer has to be completely enwrapped in filter plastica. When a surface is prepared this way, its compactability is 6-10 folds greater.

In water management, for almost any regulation structure, artificial beaches and other buildings, whether at sea, on rivers, water storages or canals – used as a substitute for natural filtration materials. The basic function is to prevent internal erosion which occurs due to the agency of filtration flow in materials of unequal composition.

For the stabilisation of fish pond embankments threatened by waves, filter plastica is used combined with stone, thus ensuring the static stability of slopes.

For cultivating fertile soil deficient areas, filter plastica serves as a separating layer, and due to its porous structure it economizes well with moisture.

In lumbriculture, since it provides ideal conditions for worm growing, both in small and large, public sector farms. On a very fertile and loose soil, filter plastica prevents the loss of worms into the ground. It is also recommended to cover hatches with filter plastica since it retains moisture and prevents the quick drying of hatches.
