Andacrib is a modular precast concrete crib retaining wall system which has been designed to cater for the most onerous loading conditions demanded of structures within the highway, industrial and commercial sectors.
Andacrib’s unique design, incorporating generous header to header bearing surfaces, ensures that all primary loads are remote from the exposed face. The design also allows for the various header lengths to be mixed within the same structure for maximum economy, whilst maintaining a consistent visual appearance.
Andacrib header units can be linked into double or triple skin walls, whilst internal and external curves can be formed.
Andacrib’s flexibility enables it to be utilised in a variety of situations:
- Road and railway embankments and cuttings
- Bridge and underpass wing walls and approach ramps
- Sewerage / water treatment plant developments, school, public service buildings etc.
- Airport development and improvements
- Retail parks
- Service Stations
- Car parks
- Leisure developments
