Box Jacking

Box Jacking is a trenchless method of construction that enables an underground space to be created in shallow depth and that avoids disruption, such as settlement, of important infrastructure and minimizes the impact on the surrounding environment. Box Jacking is used mainly in urban environments to place various types of structures underground, from box jacking culverts, bridges to railway underpasses. The shape and size of these varies each time, making the design stage crucial.

Box jacking or “Jacked Box Tunnelling,” as it is sometimes called, can be achieved through various specialist techniques ranging from canopies, pipe arches to anti drag systems. The technique chosen for each specific project depends on various factors which can include: a thorough Site Investigation and the infrastructure/community status at the surface. We investigate and design with the utmost precision before work commences.
