Underpinning is applied very effectively in a wide range of constructions, including the following: historical buildings with potential change of use, monuments, works to provide construction protection from adjacent excavations, addition of basements etc. It can also be used in dealing with failures which may be due to insufficient planning or change of geotechnical conditions.
Underpinning techniques include the following:
- Construction of piles / micropiles
- Jet Grouting
- Compaction Grouting
- Injections with chemicals
- Horizontal micropiles (Forepoling)
