I have seen allot of people use fake rock for different parts of their reptile enclosures. I looked into it and saw people using grout and Styrofoam with sealer to make cool looking things. At the same time they were only making structures for smaller reptiles. So I was wondering what some of you have done to make fake rock type things before, and how would I go about beefing up the strength of it to hold a full sized Salvatore? I was thinking of wood and concrete then sealing it with nontoxic sealant. Then the issue of weight comes up as trying to make basking spots and water holes for 2 8 foot reptiles.
