PRS-Neoweb is a cellular confinement system (geocell) developed and manufactured by PRS Mediterranean Ltd. Composed of ultrasonically welded strips, the Neoweb geocell is opened up on-site to a form a 3D honeycomb-like matrix, and then infilled with soil material to stabilize and reinforce soil. In addition to the reinforcement of the subgrade, subbase or base layer of roads and railways, cellular confinement is also used for soil stabilization and erosion control in slopes, channels, retention walls, reservoirs and landfills.
Neoweb is manufactured from Neoloy, a novel polymeric alloy (NPA), which provides a higher modulus, creep resistance and tensile strength to geocells than commonly available HDPE ( High-density polyethylene)(Pokharel, et al., 2009). Research has shown a stiffer geocell wall retains the cell geometry (dimensional stability) better and therefore confinement and reinforcement. Neoweb is a sustainable solution for road construction as it enables the use of locally available but marginal soils for infill, thereby saving virgin aggregate; reduces the pavement layer thicknesses; and extends the service life of pavements, and thereby lowers operating and maintenance costs.
