Installing an Andacrib retaining wall

Common uses

Provide retention when cutting into an embankment to create more space
Supporting highways and rail embankments where 120 year design life is required
Where a robust durable method of retention is required
Have been used for flood alleviation schemes and aquatic environments


The Andacrib concrete system is a cost effective and aesthetically pleasing ‘soft’ faced alternative to traditional retaining walls. Pre cast concrete header and stretcher components are machine paced to create a cage which is then filled with stone. (75mm down) Planting bags may be installed within the Andacrib to allow feature landscaping of the Andacrib face.

Our Andacrib concrete system which is designed to both BS EN1997-1:2004 and BS EN1992-1-1:2004-Eurocode 2, is manufactured from 50 N/mm2 concrete and has a design life of 120 year.


Highways Agency approved system with 120 year design life
Quick to construct with up to 40m2 per day possible
Machine placed components and infill, so little or no manual handling
Thinner system depth required than gabions, so less excavation
