Sand soil improvement construction equipment vibroflotation compaction

What is Vibroflotation technique?
It is a Specialist Deep Foundation Technique used for Ground improvement to considerable depth, up to 75 meters. It uses a probe called Vibro-flot (which could be powered electrically or hydraulically) to strengthen the soil by deep compaction to make the soil suitable to support proposed imposed load.

Vibroflotation benefits
The deep vibro techniques present a very versatile ground improvement method that can be adjusted to a wide variety of ground conditions and foundation requirements. Its execution is comparatively fast even if large volumnes of soil are to be improved and subsequent structural works can follow very quickly.The soil improvement enables the contractor to utilise standard shallow footings which,in turn,leads to additional savings.
Another advantage is the environmental friendliness of vibro techniques,as natural and in situ materials are used. In addition, only a comparatively small quantity of soil is removed during the process.
