DRAINING GROUND
WITH GABBIODREN® |
Gabbiodren® is a prefabricated drainage element consisting of a gabion basket of galvanised steel wire which guarantees high mechanical resistance and low deformation in working conditions. The cage is internally coated with nonwoven geotextile of high hydro-mechanical performance, which acts as a filter to avoid that the ground surrounding the panel should block the draining core made up of polystyrene-chips of selected size.
What is it used for?
It is used to provide a number of draining interventions as a substitute for natural inerts such as gravel or broken rocks.
After installation, it acts as a real prefabricated draining trench with all the advantages offered by a material which is very lightweight (from 10 to 20 KG), resistant, quick to install and constructed according to strict quality standards.
How to use
Gabbiodren® exercises an action of attraction of leach waters in the soil and, at the same time, an action of "uptake" and "drainage", as it works as a traditional "French" trench.
In dimensioning trenches with Gabbiodren®, it is important to verify the permeability of the trench base so as to avoid dispersions of intercepted groundwater.
Two situations may be encountered: the first for the use of a simple panel, the second for the use of a panel with the base coated in Gabbiodren® waterproof sheath.
Drainage at the back of retaining walls
Retaining walls are definitive structures and in most cases are built at the foot of a cliff or on a horizontal plane. With the Gabbiodren® panel it is possible to achieve an effective system for the drainage of rainwater and of infiltrations at the back of the retaining walls.
As can be seen in figure 1, two Gabbiodren® draining panels have been placed at the back of a retaining wall, one above the another, in order to form a sort of draining chimney where upstream water can be channelled and drained into the discharges. |
