Quantum has utilised and developed the Crib wall technique on a wide variety of projects requiring temporary of permanent engineering solutions. They are primarily used with compacted embankments, cutting and bridge abutments and offer significant cost savings over other, more traditional methods and can be adapted by our specialist engineers to meet your precise requirements.

Crib walls are constructed by interlocking individual boxes made from timber or pre-cast concrete. The boxes are filled with crushed stone or other coarse materials to create a free-draining gravity type retaining structure.

Reinforced pre-cast concrete, or timber, crib units can be brought on site ready for use. The infill is built in as each course is assembled and therefore the crib wall is essentially a fully operating structure at each stage of its construction. The use of mechanical plants is recommended to speed up the construction. Experience has demonstrated that Crib walls use less concrete than a conventional gravity wall and is rapidly constructed.

Recent projects completed include timber crib walls at the Greenmeadow Springs office development in Cardiff.

Crib wall facing can also be used in composite retaining structures, such as that recently undertaken at Nailsworth, Gloucestershire, where soil nailing has been designed to stabilise the overall slope in conjunction with a timber crib facing to the structure. Thus providing the Client with a more aesthetically pleasing finish to the retaining wall.
