Texdrain
is designed to intercept and/or accelerate the
evacuation of seepage water from the pavement
structure out towards the adjacent ground,
and does so over the entire height of the road
foundation. Its makeup and its hydraulic properties
allow fine soil particles to be retained (by
separation and/or filtration).
Texdrain is
composed of a drainage core sandwiched between
two separation/filtration geotextiles.
The core’s permeability is 1,000 to 10,000
times greater than that of the existing soil. All
parts of the geodrain are composed of nonwoven
polypropylene fibers. For vertical drainage, a
pouch is created at the lower end where the perforated
pipe is inserted. The main functions of horizontal
Texdrain 80 are reducing hydrostatic pressure in
road structures and directing water to vertical
drains.
Good drainage capacity under high
pressure.
Less expensive than conventional
drainage and blind drain systems.
Installs
easily.
Quality control at the factory level.
Acts
as a water barrier at the edges of the pavement.
Increased flexibility to adapt to the excavation
profile.
Good mechanical resistance.
Large contact
surface with the soil improves water catchment
at the edges.
