Port and airport


The land available on riverbanks and coasts on which port and airport infrastructure are built can often consist of compressible terrain which is saturated with water. Given the large surface areas which is generally (several hectares) required, land for ports and airports platforms are often reclaimed from the sea by means of hydraulic or terrestrial backfill. Cost-effective ground treatment techniques are very commonly used to treat such sites.


Ground improvement works make it possible to accelerate sub-soil consolidation and thus ensure low residual settlement during operation of the infrastructure. When the foundations of the infrastructure require, intensive treatment of filled materials can increase their load-bearing capacity and reduce thrust on quay walls. In cases of strong seismic loading, the treatment can include measures to reduce the risk of liquefaction.


This type of project calls for the use of substantial resources to treat large surface areas within a relatively short period of time.
