The compound geomembrane with non-woven geotextile is heated by a oven at one side or two sides of the film, and the geotextile and geomembrane are rolled to form a compound geomembrane. With the improvement of production technology, there is also a process of casting technical to make composite geomembrane. The form has one cloth and one film, two cloth and one film, two film and one cloth, and etc.

As the protective layer of the geomembrane, the non-woven geotextile can protect the impervious layer from damage. In order to reduce the ultraviolet radiation and increase the anti aging performance, it is best to use the embedding method for installation.

In construction, the base surface should be leveled with sand or clay with smaller diameter, and then the geomembrane is laid. Compound geomembrane should not be stretched too tight. The ends embedded in soil section corrugated, finally paving geomembrane with fine sand or clay layer about 10cm transition layer. The 20-30cm block stone (or concrete precast block) is built as the protection layer. In the course of construction, we should try to avoid the stone on the geomembrane directly. It is better to carry out the construction of the protective layer at the edge of the membrane. The connection between comound geomembrane and surrounding structures should be anchored with expansion bolts and steel strips. The connection area should be brushed with emulsified asphalt (thick 2mm) to prevent leakage.
