FlexMSE® is a patented vegetated retaining wall system for erosion control, landscaping, major infrastructure and bank stabilisation.

The system uses MSE (Mechanically Stabilised Earth) principles along with geotextile technology.

Non-woven FlexMSE® GTX bags are used in combination with patented 100% recycled interlocking plates to create strong, flexible block structures.

FlexMSE® does not require footing, rebar or specialised equipment to install.

Construction

FlexMSE® bags are filled with a mixture of sand and compost, and can be formed into near-vertical (85°) retaining walls, green landscaping structures and erosion-resistant sidings to rivers and coastlines.

The patented interlocking plates, made from 100% recycled materials, are placed between the layers of filled bags to add to the strength and stability of the structures constructed at a 1:1 ratio.

FlexMSE® is commonly used in conjunction with geogrid products and earth / soil anchors.

Vegetation options

FlexMSE® is suitable for hydroseeding, live staking, live planting and brush layering.

FlexMSE® units and proprietary fill media are water- and root-permeable.

Longevity

FlexMSE® has a 120-year ATSM rating and a 75-year manufacturer's warranty. FlexMSE® structures can withstand almost unlimited differential settlement (up to 2m over 10m stretch).

Support and distribution

FlexMSE® is distributed by Gravitas International Ltd. Gravitas is CPD accredited and is a business partner of CIWEM. FlexMSE® can be procured from dedicated dealers throughout the UK and the Republic of Ireland. System CADS are available for any project.
