How do you stiffen a fence post?
The most common method is by adding concrete around the post. To do this, you’ll need to use a post hole digger to dig out a square or U shape around the post large enough to accommodate a bag of concrete mix.
Mix the concrete with water in a bucket according to the directions on the packaging, then pour the mixture into the hole around the post. Once the concrete has been poured, use a trowel or your hands to carefully pack the concrete around the post.
It’s important to make sure that the concrete is firmly packed and that the post is standing upright before the concrete sets.
Another potential way to stiffen a fence post is by using hydraulic cement. To do this, you’ll need to first run a hole in the middle of the post using a power drill. This hole should be slightly larger than the diameter of the hydraulic cement.
Then, mix the hydraulic cement in a bucket with water according to the instructions on the packaging. Using a rubber mallet, pack the hydraulic cement into the hole, making sure that it is applied evenly and that the post is standing upright.
This method is more time consuming than the first, but results in a stronger, more rigid fence post.
Does spray foam adhere to wood?

Because of its superior denseness, high density foam is often more expensive than other types of foam; however, it is a worthwhile investment as it will last much longer and provide superior support.
What is concrete lifting foam?
Concrete lifting foam is a polyurethane foam that is used to raise and level sunken concrete. It is injected beneath the concrete surface using a large pressure machine. The foam expands when it contacts moisture and forms a solid base beneath the concrete to help raise and stabilize it back to the desired level.
In addition to raising and leveling sunken concrete, foam injection can be used to fill voids formed by soil erosion and shrinkage, close joints and cracks, and correct settlement issues caused by poor soil compaction.
It can also be used to fill around inefficient footings and pipe penetrations. Additionally, the cured foam stays flexible and acts as a cushion to protect the concrete from further movement. It can also be used as an alternative to mudjacking or slabjacking, both of which involve significant labor and require significant downtime.
Concrete lifting foam is a quick and cost-effective way to address these issues and help preserve the value and integrity of a structure.
