A sinking crawl space can mean a few things, but it’s likely that you’re wondering this because something about the floors in your house just feels...unsafe. Maybe they’re slanting, or feel soft when you walk on them - regardless, you know something is wrong.
Scroll a little for more information on foundation/house settling - we’re going to just talk about the crawl space here. Especially when there are water issues, crawl space support beams can weaken. This is exacerbated by the presence of mold, which loves moisture and organic material (like wooden beams) and can further degrade the beams. This creates soft spots in your floor as the beams bow and even break.
We use SmartJacks, which are steel support posts, to stabilize and reinforce your crawl space. We can sister wooden or even steel beams to the existing structure to add stability in conjunction with the SmartJacks.
