GeoSeal GCL Membrane

GeoSeal GCL Membrane is an impermeability material formed by placing natural sodium bentonite material in between two geotextile layers during production. As a result of contact of the bentonite with water, it swells and an impermeable layer is formed due to the constriction with geotextiles. When water is withdrawn, it restores to its original condition. This cycle is continuously repeated and does not affect the waterproofing properties of the material.

• When compared to compressed clay layer application, it provides significant cost effectiveness.
• When compared to clay layer with identical permeability, it fulfills impermeability function better with a volume of 100-150 times less than the clay layer. It also ensures significant saving on costs such as storage and transportation.
• It has superior hydraulic and mechanical properties thanks to the natural bentonite and surrounding woven and non-woven geotextiles.
• No special equipment is needed for placing the rolls.
