FAQs

 

What is a timber crib retaining system?

A timber crib retaining system is a cellular mass-gravity retaining wall.

The finished structure’s inherent weight and collective mass allows it to retain the target material without being destabilized.

It is constructed using individual sections of interlocking pressure treated timber to form a framework which is then filled with aggregate during assembly to add weight and stability to the structure.
