Stormwater Management

Supporting effective water drainage, filtration and long-term system performance.

Reliable Stormwater Management

Stormwater management systems are designed to collect, guide, infiltrate or temporarily store rainwater in a controlled way. Whether used along roads, in drainage trenches, retention basins or other civil infrastructure projects, these systems need to remain stable, permeable and protected from clogging over time.

Our needle-punched nonwoven geotextiles support stormwater management by combining separation, filtration and drainage in one functional layer. Installed around drainage aggregates, trenches or water management structures, the geotextile helps prevent surrounding soil from migrating into the system while still allowing water to pass through.

Without a suitable geotextile filter layer, fine particles can enter the drainage structure and gradually reduce its capacity. This can lead to clogging, slower water discharge, increased hydrostatic pressure and reduced system efficiency.

By keeping soil and aggregate layers separated while maintaining water flow, our geotextiles help stormwater systems perform reliably throughout their service life. They contribute to cleaner drainage layers, more consistent infiltration and improved protection of the surrounding infrastructure.

Key Benefits

  • Separates surrounding soil from drainage aggregate or storage layers
  • Supports filtration by retaining fine particles while allowing water flow
  • Helps prevent clogging in drainage trenches and stormwater systems
  • Contributes to efficient water infiltration, collection and discharge
  • Reduces the risk of hydrostatic pressure build-up
  • Maintains the long-term permeability of the drainage structure

Example of a Layer Structure

A nonwoven geotextile is typically used as a filter and separation layer around the drainage or storage zone of a stormwater management system.

  • Surface layer
    This may be a road surface, paved area, landscaped zone or open water collection area where rainwater enters the system.
  • Drainage or storage layer
    A granular aggregate layer, drainage trench or water storage zone that collects and temporarily holds stormwater.
  • Nonwoven geotextile filter layer
    Installed around the drainage aggregate or structure to prevent soil particles from entering while allowing water to pass through.
  • Perforated drainage pipe or outlet system
    Where applicable, this collects and transports water away from the drainage zone.
  • Subgrade soil
    The natural or prepared ground surrounding the stormwater system.
