Caisson Shaft Sinking
Jacked caissons can be constructed from 2.40m to 25.00m diameter. The company has the expertise to construct shafts in all types of ground conditions.
Caisson shaft sinking is the preferred method generally for smaller diameter shafts, especially in poor ground conditions, such as saturated sands and gravels.
Underpinned Shaft Sinking
Generally for shafts larger than 20.00m diameter the underpinning construction method is used, however ground conditions must be suitable, and firm, dry clays and rocks are most appropriate.
We own a large range of specialist plant and equipment, and have a vastly experienced workforce and management team to deal with any form of shaft construction required.
