What is interior piling?
Interior piling consists in stabilizing the foundations of a building without having to excavate. The piles will be installed from the inside of the building and the earthwork around the foundations will be saved. It is a technique mostly used when the neighboring buildings are stuck to the one to pile. We can therefore stabilize the 4 foundation walls since the 2 adjoining walls cannot be reached from the outside.
In some cases, a new house may need to be rammed following its construction. If the bearing capacity of the soil has not been verified by the contractor and the building requires stabilization in the years following its construction, we can install piles from the inside if the earthwork is new and the basement is not finished.
Steps to install an interior foundation stabilization system
- Provision of an engineer’s plan
- Demolition of the concrete slab at the pile areas
- Installation of anchor shoes at the foundation
- Driving the piles to bedrock
- Straightening and stabilizing the foundation
- Welding the piles to the anchor shoes
- Filling the piles with concrete
- Closing the concrete slab
What are the advantages and disadvantages of stabilizing the foundation from the inside?
Installing foundation piles with anchor shoes inside a building has various advantages such as
- Lower costs because no exterior excavation is required
- Work can be done throughout the year (especially in winter)
- A slight impact on the property
- Preservation of earthwork elements
- A quick turnaround time
However, you should know that there are also limits when you want to carry out this type of work:
- Impossibility to waterproof the foundations in case of waterproofing problems
- No repair of the foundations from the outside
