The use of this type of material has many different functions such as drainage, filtration, reinforcement, erosion prevention and protection. They are mainly applied in projects such as roads, reservoirs, landfills, drains, etc.
In the case of the rehabilitation of the Martorell station railway tunnel, carried out by the construction company UTE Castellbisbal-Martorell, formed by the companies DRAGADOS and TECSA, GEOFORCE, a non-woven geotextile made of 100% polypropylene mechanically bonded by a needlepunching process, was used.
To know more in detail this place, the Martorell station is a railway station called Castellbisbal located in the municipality of the same name, the station of the R4 and R8 lines of Rodalies Renfe of Barcelona.
Why was this type of material chosen?
In the case of the Martorell railway tunnel, our GEOFORCE geotextile was used as a separation element in order to generate a discontinuity between the existing lower layers and the new foundation slab.
The high mechanical performance of this highly durable polypropylene geotextile helps to protect the impermeable layers of the tunnels as well as to separate the soils, make drainage filters, load distribution, protection, etc.
Some of the advantages of GEOFORCE geotextile are:
Finally, we should mention that this GEOFORCE geotextile fulfills a series of main functions such as:
The result of this rehabilitation was a tunnel perfectly conditioned and reinforced for continuous use by railroads and for a long service life.
