Enviroweb® filled with concrete, produces a durable, erosion-resistant lining system of uniform thickness that retains flexibility and to conform to potential subgrade movement. The light weight and flexible lining adapts to a wide range of channel geometry.

Normal drying shrinkage of the concrete infill material gives the entire lining surface an ability to drain ground water from the subgrade. The uniformly distributed shrinkage also enhances the system’s ability to articulate in case of subgrade deformation or scouring on the channel bed and slope.

Due to the textured sheets of the Enviroweb®, a mechanical bond is maintained between the cell wall and concrete which locks the concrete infill into the individual cells of the system. Moreover the perforations allow cross-cell flow of concrete, providing superior locking of the concrete infill into the individual cells of the system. Thus the total system behaves as a flexible concrete mattress.

The Enviroweb® lining systems acts like a large single slab as the sections are tied togather and filled with concrete.
