WHAT IS FOUNDATION UNDERPINNING?

  • Helical Pile Foundation Underpinning

OVERVIEW

Underpinning is the process of altering a structures method of support. This can be accomplished by either augmenting the existing soil to increase its load carrying capacity or by adding new structural elements to transfer the load to a deeper more competent soil layer.

ADVANTAGES

  • Lift Foundations That Have Already Settled

  • Increase Carrying Capacity of Foundations When Planning Expansions

  • Works With Small and Large Structures and in Limited Access Areas

WHEN IS UNDERPINNING NEEDED?

The need may arise from any of several factors, including, but not limited to:

  1. Foundation has begun to sink, crack, or develop other signs of a compromised foundation.
  2. Inadequate soil strength to support the structure, such as organic layers.
  3. An event which may cause erosion of the soil beneath a foundation, such as a flood or broken pipes.
  4. New construction adjacent to and/or below an existing structure’s foundation elevation or vibrations from new construction activities may necessitate underpinning existing structures.

THE UNDERPINNING PROCESS

The most common method is by retrofitting a shallow foundation with small diameter piles. These may be installed by several different methods including rotation, driving or hydraulically pressing structural steel elements into the ground until they reach a competent soil level. The piles/piers are then attached to the foundation by a steel bracket, which also facilitates pre-loading the pile sufficiently to support the foundation without needing movement to mobilize pile capacity.
