Underpinning is traditionally used to support structures that have either failed or subsided to a point where structural rectification is required. At SFL Piletech we use a variety of techniques to underpin structures including the conventional bored pier with head stock, screw piles and chemical grouting. Through extensive R&D we developed a unique method using “jacking” technique to utilise single screw pile underpinnings at each foundation.

Underpinning can be used on a variety of structures and we specialise in rectification of residential foundations, commercial and industrial foundations as well as more diverse underpinning including canal revetment and difficult to access sites.
