No, the fiberglass itself is in good condition. It is just bulging out. Below is a photo that shows what is happening. The bulge is larger than it appears in the photo, the lighting was less than ideal to show it properly but essentially it continues to just below the pass through window.
I did get a response from Grant at Bigfoot and this is what he said.
This is the basement. The bottom horizontal under the main floor is glass in support walls.
The upper walls are glued in with 2 vertical plywood strips up each side of the 4 ft wide center section.
Seems like the bond above floor level gave way from the plywood.
