BBA HAPAS certification awarded to FLEX MSE®
Vegetated Wall System.

The award winning Flex MSE Vegetated Wall System is a carbon friendly alternative to concrete and gabion baskets, now offering an accredited BBA HAPAS 120 year design life, both in or out of water.

Using MSE (mechanically stabilised earth) principles along with geotextile technology, the combination of nonwoven Flex MSE bags and patented interlocking gripper plates allows for strong and easy-to-install geo-modular block structures, leaving a long lasting and environmentally friendly approach to retaining walls, with no limitations on height.

Working to create the best places for people, wildlife and to support sustainable development.
‘‘The (BBA) process has taken nearly 4 years of extensive product testing, factory assessments and site visits and is the only soft engineering solution to successfully achieve this. We design, manufacture and distribute our innovative range of product globally and it is a great honour that the product has now been finally recognised by BBA and National Highways as an accredited long term solution. With over a 1000 Flex MSE projects already completed in the UK and the focus on sustainable solutions, we are incredibly excited for the next few years ahead. ” Jacob Sallon, Managing Director, Gravitas International.
