A commonly asked question we get is “what is the difference between restumping and underpinning?”. This is quickly followed up with “which service do I need?” Although both restumping and underpinning are services that involve foundation repairs, each service is used for different footings your building may have. In this article, we are going to go over the differences between restumping (commonly referred to as reblocking) and underpinning.
Restumping is the process of lifting a house off its stumps and replacing them. This is generally done when the stumps have rotted or become termite-infested. Underpinning, on the other hand, is the process of adding support to an existing foundation. The footing which supports the building is either concrete strip footings or a concrete slab, where there is no stumps. Underpinning is generally done when the soil conditions have changed, or there has been an extension added to the building.
The main difference between restumping and underpinning is that restumping is for a house or structure built on stumps. Whereas underpinning is used when a house or structure is built on a slab. When performing restumping, the stumps are replaced. When performing underpinning, the slab is reinforced, not replaced.
So which service do you need? If your stumps are rotted or termite-infested, then you will need to restump your house. If the soil conditions have changed and your house is built on a slab you will need to underpin it.
How do I know if my house is built on stumps?
If you’re not sure whether your house is built on stumps or a slab, there are a few ways to find out. The easiest way is to look at the perimeter of your house. There are a few things to look for: If you can see stumps, then your house is built on stumps; if you can see vents around the base of the house, this indicates there is circulation needed for crawl space below the house.
If you’re still unsure, the best way to find out is by contacting a registered builder or structural engineer who will be able to tell you for sure.
Once you’ve determined which service you need, the next step is to contact a registered builder or restumping contractor to carry out the work. They will be able to advise you on the best course of action and provide you with a quote for the work that needs to be done, as well as inform about the risks of not restumping.
