Coppenhall Hall and Mews, an exclusive development of just 11 new homes, is built on the site of an old dairy farm in the rolling Staffordshire countryside. To create an elegant curved driveway providing access to the homes, developer Redfern Developments specified a Macwall segmental concrete retaining wall system from Maccaferri Ltd, specialists in retaining structures, soil reinforcement and erosion protection.

Constructed on a steep slope, the development comprises of eight converted barns leading up to three new townhouses built on the site of an old farmhouse. To provide vehicular access over the rising ground, an engineered retaining wall solution was required to stabilise the slope. Redfern considered a number of alternative solutions, but Macwall was selected as it could offer an engineered solution with the option of a curved structure.

Creating a sweeping gravel driveway, Macwall has been finished in a mellow red colour ‘Brindle’ complementing the old stock bricks used elsewhere on the development. In addition to providing the design and supply of materials, Maccaferri also provided advice and support during construction of the wall, which was undertaken by Redfern Developments’ site workers.

Available in a wide choice of masonry colours, MacWall engineered retaining walls are constructed from high quality segmental blocks set into a foundation of compacted granular material.

Built-in locators speed up construction by ensuring the correct horizontal alignment of blocks and that a consistent seven degree batter is achieved to enhance the appearance of the structure. A 300mm layer of free draining aggregate is placed behind the blocks and a geotextile layer is used to separate this from the structural backfill. For all engineered retaining walls, layers of Paragrid, a polyester soil reinforcement geogrid manufactured by Linear Composites and distributed by Maccaferri Ltd, are used to reinforce the structural backfill.

Maccaferri Ltd specialises in the supply of gabions, geotextiles, geogrids and geomats. In addition to a full range of products for retaining structures, soil reinforcement and erosion protection, the company offers an in-house design and consultancy service.
