When low bearing capacity or excessive building loads add complexity to a project, YGC’s knowledge of various deep foundation solutions will help ensure long-lasting structure performance.
Underpinning is the process of reinforcing or stabilizing an existing foundation by mechanically extending structure loads to deeper soil elevations.
Underpinning is the process of reinforcing or stabilizing an existing foundation by mechanically extending structural loads to deeper and more competent soil elevations.
In high urban density areas, underpinning can help protect the adjacent foundations during construction so that excavation can occur below the foundation elevation. Underpinning also adds supplementary support to old foundations or those that have experienced subsidence or heave. This process helps mitigate the risk of adjacent foundation failures and offers an alternative to foundation removal and replacement.
In projects that call for mechanical underpinning, YGC utilizes a combination of piers and brackets to extend building loads deep into the subgrade. Pile types can be helical, hydraulically driven, or drilled and grouted micropiles.
Minimally disruptive to adjacent structures
Ideal for tight work areas
Augments the structural integrity of the existing foundation
Proven installation process
Corrosion-resistant components lead to a long lifespan for the project
Can be combined with cathodic protection systems when subgrade conditions have high corrosion potential.
