The mission critical objective of reservoirs is to provide 100% protection of the reservoir geomembranes while creating stable soil, berms and slopes.

PRS-Neoweb™ cellular confinement from PRS combined with geomembranes creates protected, impermeable, non-slip and durable impoundment of water, waste and leachate. Liners are shielded by PRS-Neoweb from natural, accidental or intentional damage. Used in applications which require containment, treatment or control of water, or other liquids, PRS-Neoweb geocells are installed on top of a geomembrane on the slopes of the reservoir or containment pond. The PRS-Neoweb geocells are easily filled with concrete for effective and reliable long-term protection.

Neoloy® based PRS-Neoweb geocells are impervious to salinity, corrosion, acidity, sewage and extreme temperatures. PRS-Neoweb cellular confinement systems have considerably higher environmental resistance and durability than HDPE-based geocells.
