Pyl Brook -Design and erosion control

Continuing erosion had caused the garden to slope down towards the stream, causing it to have a reduced workable area


Project Brief

Pyl Brook is a 5.3km stream which rises in Sutton and runs through the southeast London Borough of Merton to disembougue into Beverly Brook. It is a secondary tributary of the river Thames.

Cain Bio-engineering was contacted in February 2018 by the owner of a private garden with a 25m stretch of Pyl Brook running along its side. Continuing erosion had caused the garden to slope down towards the stream, causing it to have a reduced workable area.

The Solution

A double tier “coirnet” revetment was designed and built by Cain Bio-engineering as a solution to the problem, considerably increasing the area of the garden and providing long term protection for the stream bank against erosion.

The finished project, delivered in June 2018, considerably increased our client’s garden area, and offered a long-term solution against erosion from the stream.
