Full or partial foundation replacement is a common construction process for many structures. Foundation replacement will be required if indeed the damage already done on the foundation is so bad that repairs won’t work. In addition to this, in case the cost of repair is higher, the same or slightly lower than that of full foundation replacement, then it will make sense to go for full replacement than just a foundation repair.
Reasons Why You May Need Full Or Partial Foundation Replacement
- Your foundation is constructed using non-reinforced materials such as concrete blocks, stone, or bricks
- Your concrete foundation is crumbling or deteriorating due to long exposure to water and moisture
- The foundation was not done well in the first place. The contractor failed to get the concrete mix right
- The foundation stem walls appear to have rotated out of plumb
- The cracks in the foundation are relatively bigger and far closer to one another

What To Expect With Foundation Replacement
Building new foundations requires a lot of work. The new foundations have to be constructed using very high building standards and codes. The people involved in the construction have to comply with set industry procedures, methods, and also techniques. Replacing an existing foundation is not that easy and it may require a lot of time and money. State of the art formwork will be needed for the job as well as modern survey equipment.
Typically, foundation replacement can take a few days to be completed and should follow these simple steps:
Shoring Up The Building
This is basically the process of raising the structure and then constructing some temporary shoring. This means that the load bearing is no longer laid on the foundation. This provides room for the damaged foundation to be removed and replaced.
Removing The Damaged Foundation
Once the temporary shoring is in place, the damaged foundation will now be removed. Trenching will also be done for the new foundation at this point.
Installing The Rebar And The Forms
Rebar and forms are needed to provide the reinforcement that will be critical in making the new foundation. The forms will offer support for the concrete as it cures. They will be removed as the new foundation is tied to the structure. This will take a few hours.
Once the rebar and forms are installed, there is a city inspection to make sure that things are done right. It’s a very important stage because it is designed to ensure that all foundations are constructed according to the required codes and standards.
Pouring The Foundation
Once the inspection is over and the green light is given, it’s time now to pour the foundation. This is the penultimate stage of the entire process and one of the most important ones too. The concrete needs to be mixed correctly and poured carefully so that the structural quality and strength of the new foundation is as high as possible.
Tying The Foundation
The last step is tying the foundation to the structure. The forms will be removed first and after that, the structure will be tied to its new foundation. This is often a step where mistakes can happen. However, don’t worry. We have been doing foundation repairs and replacements for many years and our team has enough expertise to ensure that the structure is tied correctly to the new foundation.
Foundation replacement is an important process that will restore the structural strength and integrity of your building. But it has to be done right and with professional foundation replacement companies, you can never go wrong.
