📣📣📣 Compensation Grouting and Fracture Grouting are advanced ground improvement techniques used to control or reverse the settlement of structures. The process involves injecting grout into the soil layer situated between the foundation being protected and the activity causing the movement, such as tunnelling or deep excavation. These methods are applicable across a wide variety of soil types, from dense gravels to soft clays and weak formations. When used either alone or in combination with

The drill and blast method is one of the most widely used techniques for constructing tunnels in hard rock, where controlled drilling of blast holes, careful charging with explosives, and sequential detonation allow for efficient rock fragmentation and safe excavation. This method requires precise design and execution to minimise vibration, protect surrounding structures, and ensure stability, making it both a challenging and fascinating aspect of tunnelling. If you would like to gain a deeper u

Permeation grouting is a ground improvement technique in which low-viscosity grout, such as cement-based or chemical solutions, is injected under controlled pressure into the pores and voids of granular soils without significantly disturbing their structure. The grout permeates the soil matrix and hardens, thereby increasing the strength, stiffness, and impermeability of the treated ground. This method is most effective in coarse sands and gravels where grout can flow freely through the void spa
