Underpinning
Covering Kent, Essex, South East London and Surrey

Underpinning just one of the highly skilled services offered by Arthur Griffith & Associates one of the South of England's foremost deep-foundation underpinning specialists.  Underpinning is the art of extending the foundation of an existing structure to a deeper elevation. This is often required when excavations are made next to existing structures or when the original foundation is settling. There are several methods used to extend the foundations of a structure - they include hand-dug underpinning piers, bracket piles, jacked piles and mini-piles. The art of underpinning requires the engineer to analyze the existing structure, determine the loads, the bearing capacity of the soils, and then design an underpinning to support the structure with a minimum of settlement. Each of these systems must be designed with a knowledge of the structure and the exact methods, sequence and craftsmanship of construction
