NON-WOVEN GEOTEXTILES – GEOTEX
WOVEN GEOTEXTILES – POLYTEX

Geotex® G34 being used in a Water Loffel retaining wall application. The geotextile serves as a filter and a seperator which prevents loss of sand particles through the face of the concrete block structure. The Geotex® G34 is especially suited to this application as this nonwoven geotextile is heat treated which bonds the fillaments together and thus prevents the fillamants from becoming de-entangled in this hydrodynamic situation as other common branded local geotextiles may suffer.

Geotex® G34 used as silt fence to prevent silt runoff from the major earth works on the project. The silt fences are 700mm high and are tucked into a 150mm deep anchor trench at the base. This prevents the bottom of the fence from kicking out in a high flow situation. The fences were well supported with standards at 1m centres. The silt fences were erected in such a way that they were at a soft angle to the direction of flow and staggered so as to slow the flow down and to make the water path flow in a zig zag fashion thus enhancing the effect of slowing down the water flow velocities and making the silt fences more effective in collecting more silt.
