Geotextiles are fabric materials manufactured by fusing (with chemicals or heat) or mechanically combining (needle-punched or stitch bonded) a loose web of polymer fibres. The most common are needle-punched geotextiles made of continuous long or staple fibres.
At the same surface mass (in g/m2), geotextiles are characterized by different tensile strength, porosity and permeability – depending on the fibres used (PP, PES continuous long or staple fibres) and the finishing process (calendering).
Geotextiles used for filtration, protective and drainage layers must meet two basic hydraulic criteria: permeability and clogging behaviour.
The permeability coefficient of geotextiles should be much higher than the permeability coefficient of the soil or the protected ground. The clogging criterion depends on the porosity of the geotextile and the grain size of the soil. The primary condition is that the fine soil particles do not cause clogging, i.e. sealing the filter material or silting the drainage.
Geotextiles for engineering and environmental protection applications are made mainly of polypropylene or polyester fibres.
Polypropylene and polyethene (polyolefin) geotextiles are characterized by high mechanical resistance and very good biological and chemical resistance. They are, however, weak to solar UV radiation, which should be considered by contractors working in open areas (polypropylene geotextiles should be covered). Additional agents can be added during production to make the textiles radiation resistant, which raises production costs. Polyester geotextiles are characterized by very good UV radiation resistance but have lower mechanical resistance and weaken when in contact with alkalis (e.g. cement).
Geotextiles can significantly extend the life of structures, increase their resistance and offer much better drainage than traditional methods.
1. ROADS, TERRACES, PARKING LOTS, GARAGE DRIVEWAYS
The sand remains clean, and the surface is smooth and even; the slabs do not wobble.
2. BASEMENT DRAINAGE
The basement drainage is not silted, the water is drained, and the basement walls remain dry.
3. DRAINAGE DITCHES
The fine particles are retained, and the gravel remains clean and does not silt.
4. PONDS
The liners are protected and remain undamaged; the pond remains watertight.
5. POOLS
The foil is protected and remains undamaged; the pool stays watertight for a long time. Due to the mechanical properties of geotextiles, expensive materials such as foils and geomembranes are protected from damage caused by roots or sharp stones. If necessary – in case of heavy loads – the geotextile can be placed in two layers. There is always a lot to do around the house; these tasks should be fun and enjoyable.
6. PLAYING FIELDS, PLAYGROUNDS, HORSE RIDING ARENAS
The protective layer does not mix with the drainage, the original thickness of the layer is preserved, and the horse’s hooves are protected.
