Basement Services

Our structural engineers’ design both new and retrofit basements for either commercial or domestic use including basements under gardens. Structural engineering services include site investigation reports, trial holes, party wall monitoring and site visits throughout the construction phase. We have experience with various underpinning methods, including those in difficult ground conditions. Our work also involves properties that have experienced movement and require the traditional underpinning.
