Toppled Wood Support Posts
Some of the support posts in the crawl space were toppled over, providing no support to the floor.
DIY Floor Support Not Recommended
Supporting the floor with wood blocks is not recommended, especially when the crawl space has moisture issues that will contribute to wood rot. It is only a temporary solution until the wood blocks sink into the wet soil or rot from moisture exposure.
More DIY Floor Support
In another area, the floor was being supported with concrete blocks and small pieces of wood. Notice the wood on the right side is not level and is split from the weight. These supports will only work temporarily with the potential for significant damage to the floor if left this way.
Heavy Kitchen Equipment
The kitchen area had large industrial size equipment contributing to the weight on the floor. Notice under the stove the floor is bending slightly under the pressure at each leg.
