Cut-off walls act as containment structures: they can be installed as part of a storage tank, like a Liquid Natural Gas (LNG) storage project, or a silo to isolate an area and prevent any migration of material, generally in liquid form, into or out of the surrounding ground.
Operations at large industrial or energy facilities can contaminate the ground on which they are built. Cut-off walls prevent soil contamination by trapping liquid pollutants. They can even stop the spread of contamination when the soil is already polluted, by creating a watertight belt.
As a ground engineering specialist operating worldwide, VSL-Intrafor has a wealth of experience, qualified employees, and a global network of branches and regional subsidiaries.
This allows it to offer a comprehensive package of construction services. In particular, it has patented a proprietary method that significantly speeds up the construction phase for cut-off walls and ensures excellent productivity and verticality.
VSL’s design & build package for cut-off walls can also be complemented by prior geotechnical and hydrogeological investigations including site analysis, to guarantee the best results in terms of waterproofing and performance of storage tanks and silos.
