Drainage geocomposites
Drainage geocomposites – the principal objective of producing reinforcing geocomposites is to obtain materials combining the best physical properties of geotextiles and related products. Such a geocomposite allows for making use, while arranging one layer, of the advantages of geononwoven and ferroconcrete geomesh, which, through stitching through or thermal connection, are formed into one unit. Drainage geocomposites allow for obtaining important technical advantages with simple installation. These advantages include: availability of materials, strength and stability of slopes, good structure dewatering, resistance to mechanical damage.
Geocomposite parameters:
- Surface mass: from 140 g/m2 to 1100 g/m2
- Resistance to stretching: from 8,0 kN/m to 230,0 kN/m.
- Relative elongation at the maximum load: from 2 % to 75 %
- Puncture forc (CBR method): from 1,2 kN to 3,0 kN
- Water flow rate, perpendicular to the plain: from 0,1 mm/s to 2,9 mm/s.
Application:
- additional drainage of waste landfills and taking over water leaks from untight structures,
- discharge of gases and natural drainage of covered waste landfills,
- tunnels, resistance walls and underground structures,
- ground drainage in geotechnical structures,
- sites, parking lots and sports stadiums,
- reduction of aggregate costs and duration of an investment because they are easier and quicker in use than traditional filtering and water discharging methods,
- supplying permanent drainage resistant to compression or thickness reduction,
- ensuring a possibility of obtaining larger useful area.
