Paradrain ®

PARADRAIN® GEOMESH IS A SPECIAL TYPE OF MESH
FOR GROUND REINFORCEMENT. IT IS COMPRISED OF
THERMO-WELDED STRIPS THAT INCLUDE A DRAINAGE
CHANNEL AND A SEPARATION GEOTEXILE.
THE FINAL RESULT IS A RESISTANT GEOMESH
WITH A HIGH DRAINAGE CAPACITY

Each strip of ParaDrain® has a core of polyester filaments covered by a protective layer of polypropylene. The specific strip structure of the geomesh has allowed a lengthwise channel to be designed in each strip to drain the water and separate it from the ground using a strip of non woven geotextile connected to the reinforcement strip.
Thanks to their structure, ParaDrain® geomeshes consolidate the soil while dispersing the water present in the ground.
ParaDrain® geomeshes have a range of variable mechanical resistances between 50 and 200 kN/m in the lengthwise direction and 15 kN/m sidewise.
Its main fields of application are embankment reinforcement, in reinforced earth applications using cohesive matrix soil, or in combination with the TRESMA® structures (when the wall height does not allow use of TRESMA® as the sole reinforcement).

DISIPACIÓN DE LA PRESIÓN DEL AGUA EN LOS POROS

Se han realizado muchos tests para determinar la disipación del exceso de presión del agua en los poros del terreno estructural. En los experimentos se ha utilizado la arcilla “English China Clay” (permeabilidad k= 1 x 10-11). Los resultados demuestran como después de 48 horas el exceso de presión debido al agua ha llegado a ser el 20% de su valor inicial a distancias de 70 y 35 mm del elemento de ParaDrain® y sólo el 10% de su valor inicial en la zona más cercana a ParaDrain®.
