I have done a lot of prop work with 2 commonly used items in haunt building. Chicken wire and PVC pipe. These two items can be used to form and create just about anything the imagination can come up with. I have created cave walls with chicken wire, rib cages, fake rocks and all sorts of other items. Then PVC I have used to build the frame of corpses, tunnel wall structures, stands and the list goes on. I am going to start of our Prop Building 101 with a 3 part video series I found and the first video is PVC 101 Part 1 of 3 and is done by a haunt club on the east coast.
