Permeation Grouting and Soil Stabilization
A common problem in both new and existing structures is soil erosion leading to undermining and destabilisation of structures. This can be a very expensive and time consuming problem to solve, and typically one that can’t be forecasted or costed. Unlike traditional under pinning techniques requiring significant excavation and propping the simple solution of injection into the soil can be a much better solution.
There are several methods Portolesi employs each of which is specific to the unique site requirements factoring soil type, compaction, load, structure, access, speed of delivery to name a few. Ultimately our experienced staff will assess the works and develop a remedy for whatever combination of factors they find.
