Before diving into the best stabilization options for your needs, you should probably first think about stabilization options that don’t work. These tend to be the most common DIY stabilization options, but unfortunately, they’re actually not very effective.
You should definitely reconsider your options if you’re thinking about putting one of these in as a stabilization option.
Some people try to hold up a sinking joist or post with a concrete column. The logic is typically that because concrete is able to hold up so much weight, it’s a useful tool for holding up home foundations, which support a lot of weight.
The main downfall of this is that there’s no way to adjust it. If the soil under your home shifts or the concrete column moves for some reason, you won’t be able to move the column back to its perfect location.
Because it’s essentially impossible to change a concrete column and it takes a lot of time to cure, JES doesn’t recommend concrete columns. They’re likely to be more trouble than they’re worth.
“Shimming” is a method used to make your current products fit the space by adding additional items underneath it. In home repair, you’ll typically use scraps of wood to fill up empty space between the current post and the top of the crawl space.
However, shimming actually isn’t an effective tool for this problem. It won’t actually lift up the floors; it’ll just stop them from dropping further. Plus, it’s not even a long-term solution, as the wood scraps typically don’t hold up the constantly sinking floor.
Overall, this isn’t an effective fix and barely qualifies as a fix in the first place. JES recommends utilizing a longer-term fix for your home’s sinking floors.
Light-Duty Jack Posts
These are an option more similar to crawl space jacks that JES uses. They’re more lightweight, more portable, and often more user-friendly than professional house foundation support jacks, making them very alluring to DIY homeowners.
The thing is, the light-duty nature of these tends to work against them. Light-duty jack posts tend to only hold up a small amount of weight, making them bad foundation lifting jacks. They also don’t address weak soil problems.
Even though this gets closer to JES’s preferred solution, it’s still not a good substitute. You should only use foundation floor jacks that can actually stand up to the problem.
