So you know the floors and sagging and can feel that the floor is not level, but what created the problem of sagging floors over a crawl space?
1) Existing block or brick columns are spaced too far apart. When a crawl space is built, block or brick (even wood) columns are located throughout the crawl space to support the weight of the structure above. If those columns are spaced too far apart, the beam or girder can become overloaded and sag between the columns. When the girder sags, so does the floor above it.
2) Weakened floor joists and girders due to moisture and wood rot. Because crawl spaces are often unsealed from the earth, excess moisture and humidity is a problem. And what happens to wood when it has been exposed to moisture and humidity? It begins to rot, get moldy and become weak. Yuck! The weakened girders and floor joists can not support the weight above, and the floor above the crawl space become bouncy, soft and may begin to sag.
3) Existing columns settle due to weak soil. Weak soil can cause the existing columns in the crawl space to sink or settle, often creating a gap between the top of the column and the bottom of the girder it was supporting. Once the column settles, then the girder sags and the floors above sag. It’s a chain reaction.
