Andacrib Concrete Crib Retaining Walls
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's flexibility enables it to be utilised in a variety of situation:
- Road and railway embankments and cuttings
- Bridge and underpass wing walls and approach ramps
- Sewerage / water treatment plant developments, schools, public service buildings,etc
- Airport development and improvements
- Retail parks
- Service stations
- Car parks
- Leisure developments
