Mold and Moisture
While this may just look like some mud, you can actually see how the wood has soaked up the water, which encourages mold growth. If you look on the right side of the picture, you can see mold.
Even more mold!
This is a picture that is further in the crawlspace. You can see how moisture has caused mold growth near the wall and on the fallen insulation.
Another area of wetness
A similar view as the first picture. It shows how the wood has began to soak up some water.
Previous Liner
This is an example of the previous liner, which obviously was not preventing moisture from entering the crawlspace, nor draining any water that made its way in.
After Installation of CleanSpace
This is the installed CleanSpace, creating a crawlspace that is almost separate from the outside world.
