CoirLog

—  Biodegradable silt worm

Description: 

CoirLogs provide erosion and wave control structures in riparian zones, and sediment capture in drainage lines and swails. 
CoirLogs provide protection while vegetation establishes and takes over the long term stabilisation.
CoirLogs are an environmentally friendly alternative to hay bales.  Hay bales tend to break up easily, have a short life span, are difficult to handle, and are usually contaminated with weed seed.™

Benefits: 

SILT RETENTION
CoirLogs can be placed in swail drains, around grates, on steep slopes to collect silt, and used to slow water velocity, reducing erosion.
RIVER BANK PROTECTION
CoirLogs can be used in river channels, streams and creeks to help stabilise bank toes and provide structure to benching techniques.  CoirLogs can be stacked one on top of another to form a wall structure while vegetation establishes for long term stabilisation.
 

Applications: 

For sediment entrapment, wave and wind protection of:

  • River banks and toe protection
  • Coastal wave erosion
  • Wetland erosion
  • Swail drains
  • Steep batters and sand dunes
  • Straw bale alternative
  • Rip rap alternative
  • Building sites
