The geotextile filter fabric will minimize hydrostatic pressure and prevent loss of soil during drainage and drawdown.
Gabion retaining wall drainage.
Without retaining wall drainage hydrostatic pressure will push wall over.
When building a retaining wall lay perforated drainage tubing at the base of the wall slightly above ground level so runoff can drain out without undermining your wall ruggedthug.
A retaining wall is built to hold back a certain amount of soil.
Gabion walls are retaining walls built by stacking stone in a gabion cage or gabion basket that can serve many purposes but are most often used to create tiered or leveled ground in gardens.
For small domestic retaining walls weed mat can be used instead of the geotech filter fabric.
The design of a properly built retaining wall resists the force of the soil behind it and prevents caving buckling or leaning.
When a retaining wall is in the way water pushes against it and the wetter the dirt becomes the more it pushes.
Geotech filter fabrics are used to prevent silt and clay form clogging up the retaining wall s drainage system.
To ensure the gabions continue to look great well into the future we recommend installing a quality non woven geo fabric material under and behind when building gabion walls.

Why proper drainage is important for retaining wall performance.
Geotech filter fabrics are used to prevent silt and clay form clogging up the retaining wall s drainage system.
Geo fabric will allows water to flow through the gabion structure no pressure build up behind the wall however soil particles will be contained.
However retaining walls are built with a certain capacity in mind.
Add retaining wall drainage metal and perforated drainage pipe.
Gabion retaining walls are porous and this prevents build up of hydrostatic pressure.
