Best 3 geotextile fabrics for waterproofing Echo

1, Geotextile fabric for waterproofing-composite geomembrane

When people talk about geotextile fabric for waterproofing, the first product comes to their mind are usually composite geomembrane. 

Composite geomembrane, also known as waterproof geotextile, is composed of a plastic film made of high-molecular materials such as polyethylene, and a non-woven fabric. The plastic film primarily serves the function of preventing seepage, and it exhibits outstanding tensile strength and elongation. When combined with the non-woven fabric, the composite further enhances its tensile strength and puncture resistance. It also increases the friction on the contact surface, providing greater stability. Additionally, both materials demonstrate strong resistance to corrosion, protecting against erosion and damage from various chemicals and bacteria.

2, Geotextile fabric for waterproofing-geomembrane

what is geomembrane

The waterproofing function of geomembranes lies in providing a reliable impermeable and isolating layer, ensuring that liquids or gases cannot penetrate into the protected area.Geofabric membranes are typically made from polymer materials such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyvinyl chloride (PVC).

According to surface features, we can divided it into smooth-surface geomembranes and rough-surface geomembranes.

Smooth-surface geomembranes have a highly polished surface, lacking uneven structures, and therefore possess a lower friction coefficient. They are suitable for applications where a high level of surface smoothness is required, such as in water engineering projects and landfill lining for waste containment. In contrast, rough-surface geomembranes exhibit a certain degree of roughness with microscopic irregularities, resulting in a higher friction coefficient. These geomembranes are more suitable for scenarios requiring increased friction resistance or where surface smoothness requirements are relatively lower, such as in road base waterproofing and at the base of dams, especillay in slope area. The choice between smooth and rough-surface geomembranes depends on specific engineering requirements, ensuring optimal performance in various application areas.
