Building a Green Retaining Wall in a Residential Neighbourhood in Northern England

Neoweb Cellular Confinement Strips Infilled with Local Tosoil

Challenge

The developer of this residential project needed to stabilize a claystone/sandstone slope to enable construction of adjacent apartment buildings (at distances as little as 1.2 m from the buildings).

The soil suffered from erosion and poor bearing capacity. To gain residents' approval, the solution had to be strong and aesthetic.

Since the wall would be visible from many of the properties, residents demanded a green-faced solution to suit the surrounding park landscape requirements.

Old Approach

One solution considered involved constructing a reinforced concrete wall or crib wall, which did not suit the landscape and required large quantities of steel.

Due to the proximity to the building, this solution was rejected.

Neoweb Solution

The developer installed a series of staggered Neoweb cellular confnement strips, inflled with local topsoil, to create a 6 m tall, 276 m long retaining wall.

Client Benefits

• Enhanced fexibility accommodating uneven surface contours
• Easy planting of vegetation in cells meeting demand for green solution
• Fast, easy installation requiring only minimal training
• Long-lasting, low-maintenance solution

Neoweb provided an easily built and aesthetic earth retention solution.

The project's fast installation time of only eight weeks reduced construction time by up to 30% and lowered overall costs.
