Using foam to form rock layer

2 " Foam insulation board is cut into pieces and stacked in order to make this soon to be mountain. Tunnel portals wll  be going on next followed by a layer of  Hydrocal plaster and rock castings. 
The foam is kept in place using nails. Recently, I've began using Locktite all purpose adhesive between the foam layers This seems to  work the best out of glue type agents.
