Retain was approached in late 2018 by HMH Civils Ltd., the Groundworks and specialist Civil Engineering Contractor. The consultant engineers employed by NTWDC, 3 E Engineering had carried out extensive ground investigations and conceptual designs which envisaged Crib Retaining Walls.

At an early stage Retain identified the need for a specialist Geotechnical consultant and Remedy Geotechnics were instructed. Their main areas of involvement were to do with global stability checks which required the provision of boreholes and pull-out calculations on the Huesker geogrid employed.

The final proposal from Retain considered:

• The best retaining wall system for the location: Allan Block had significant advantages in (a) lower bearing pressure and (b) less land required for the high walls as compared to other systems
• Aesthetics: The cut block facing and colour were chosen to match the architecture of the houses to be built on site
• Cost: The proposed system was significantly cheaper with the added benefit of increased garden size
