FlexMSE Bank Protection – Waterside.
Fovant Brook, Waterside
October - November 2018
- Existing logs and Chestnut posts revetment removed by hand and re-used to create small marginal habitat features.
- Cutting back the riverbank by 30cm to allow for the installation of the new revetment. The excavated soil used as backfill downstream.
- Installation of a FlexMSE wall system by placing one row of bags squarely over the interlocking plates. Bags are then compacted to engage the plate with the bag and the riverbed.
- Planting aquatic plant species across multiple zones to create a vegetated wall.
- Works were undertaken during low-flow conditions to make installation easier and outside of the salmonid spawning period.
- Due to restricted access materials were moved to site from the unloading area using a wheelbarrow.
- FlexMSE was chosen as the best method to act as a structural wall to prevent erosion further undermining the house’s foundation.
- Creation of a bio-engineered protection against erosion that supports invertebrates populations through the plantation of macrophytes.
- The new bank has been hydroseeded with a wildflower mix to increase biodiversity and aesthetics.
- Existing plants were translocated, stored safely during the project and then re-planted when the work was completed.
- The FlexMSE walls have stabilized the riverbank, hence, protecting the house.
