Needle-punched nonwoven geotextile manufactured without using adhesives or chemical additives, made of polyester and polypropylene fibre, available in lots of colours and subjected to heat bonding.
Ideal for uses such as separation membranes between soils and backfills, drainage and filtration layers, erosion control, ground reinforcement, dams, roads, pavings, protections for foundations, protection of Imhoff tanks, and asphalt waterproofing membranes.
Our geotextiles can be used for:
- erosion control
- stress relief
- Time saving for the preparation of sub-bases and execution of the works.
- Cost-effective for works construction due to the reduction in the amount of granular materials and aggregates needed.
- Savings of time and effort thanks to the ease of use of the materials.
- Greater reliability of the finished work.
- Increase in the projected lifetime of the work.
- Enhanced land protection because the use of TECNODREN reduces the quantity of aggregates used in works and is fully compatible with the environment.
TECNODREN’s excellent resistance to punching and alkalis means that it is used to protect geomembranes, to prepare tanks and is also used in the final stages of cultivating landfill sites for capping operations.
Stabilizing land, roads, motorways, airports, car, parks, railways
TECNODREN’s excellent resistance to traction, permeability and porosity make it an indispensable material for preparing land as it acts as a separating layer in such a way as to prevent contamination and mixing between the different layers of the site and backfill and at the same time acts as a water filter that does not allow the shift of solid particles and thus prevents landslides from occurring.
Roofing and tunnels
TECNODREN, owing to its chemical and physical features, protects the impermeabilising cladding used in tunnels and roofing. Its draining performance also enables effective drainage of underground engineering work, thereby preventing water runoff from creating dangerous excess pressure.
Coastal defences, water projects, canals, basins
TECNODREN also appears to be indispensable in coastal defence work, where a separating layer and filter are always required to prevent erosion of the ground and the shoreline. The same considerations apply to water projects, canals and basins, where it not only acts as a filter but may also protect geomembranes and the structure.
Foundations and supports of hanging gardens
TECNODREN’s draining and filtering functions prevent blocking of the drains at the back of the foundation and support structures and blockage of the drainage systems in hanging gardens.
Drainage and filtering systems
TECNODREN has many applications in this area. TECNODREN’s great flexibility for cladding drainage systems extends the life of the drainage systems by retaining fine particles whilst letting water through to stop the drains from getting clogged up. The host of applications vary from traditional drainage systems to sporting facilities and land drainage.
Forecourts, dry flooring
TECNODREN’s excellent earthseparating and reinforcing features mean that it is increasingly used to prepare foundations for dry flooring (concrete slabs) as it greatly increases the durability of the work by preventing the sand mixing with the layer underneath. It thus makes subsidence much more unlikely.
Waterproofing of bridges and viaducts
Thanks to its optimal properties of absorption, reinforcement, and heat resistance, TECNODREN is an increasingly popular choice for creating waterproof coverings, with big pluses in terms of fast installation and perfect adhesion to the underlying concrete.
