Bank erosion

Cain Bio-Engineering provides soft bank engineering solutions to bank erosion issues.  We have developed our own ‘Coirnet’ bank revetment for bank protection which is constructed from chestnut posts, geotextiles and backfilled with gravel.  Coirnet is resistant to burrowing animals such as the North American signal crayfish and allows for natural revegetation of the top and face of the revetment which allows plant root systems to bind the bank together.

We also offer traditional oak timber faced boarding bank protection and toe protection in the form of timber sleeper and gravel backfill.

Cain Bio-Engineering consultants will assess your bank erosion issues and recommend the best solution for your situation.
