is a general-purpose woven geotextile for use as a drainage filter and separator in all types of civil engineering, building and landfill projects. geotextile membrane is used below access roads (both temporary and permanent) to create a firm base on which to place the crushed stone foundation layer. G90 is also used in construction of equestrian arenas as a seperator membrane between the sub-base layer and the drainage layer to prevent blocking of the drainage system and to keep the surface seperate from the sub-base. geotextile membrane is also used to line drainage trenches to prevent the fine soil particles from blocking the filter stone. The woven geotextile is a high performance filter that will allow all the water through whilst at the same time preventing the passage of soil particles.  geotextile membrane cost per m2 is currently N9000
