Neoloy® Tough-Cells Category B is the most Qualified Solution for Drainage Systems, Channel Protection and Earth Retention

Qualified Neoloy Geocell

Neoloy Tough-Cells Category B – Qualified for Channels and Retaining Walls

Neoloy Tough-Cells Category-B provides strong, durable and reliable protection for earth retention walls and channels subject to high flows, typically using soil, gravel or concrete for structural infill.

Advantages of Qualified Category B for Drainage and Channels:

  • Self-draining – prevents hydrostatic pressures.
  • Flexible – prevents cracking or degradation.
  • More cost-effective – than concrete, rip-rap, gabions.
  • Non-degradable – resistant to water, UV, temperatures.

Advantages of Qualified Category B for Walls:

  • Save concrete/costs in design and installation
  • Very fast installation – does not require heavy machinery
  • A flexible system yields to earth movement (high seismic resistance).
  • More cost-effective than concrete, segmental retaining walls (SRW), gabions and green walls.
