Have seen quite a few haunts with realistic cave sets and I was wondering what the best way to accomplish this is? Wood frame, chicken wire and then spray foam? I also heard some haunts built the set with wood and even stachtites and stagmites and then coated the whole thing with bed liner spray..... Any videos out there, or can anyone give any hints....?

The way I would do it is a wood frame built from 2x2's build it the way you want it to look... then put chicken wire all over it and SHAPE it with the chicken wire. From there glue foam onto the chicken wire big chunks of foam... then carve it.

In the end you either can spray it with a gunite type of spray which would then make it feel like real stone or you can hard coat it... depending on what you want the final texture to be determines what you will or won't use. Clearly in the end you light and paint the tunnel. There are other ways to do it like make molds and pull them from resin or fiberglass or whatever but for us the simple haunt owners we have to do it the cheapest. I think the worst way would be vac form it won't look great but it would look okay.

Terror on the fox has an amazing cave.... They did it with chicken wire and spray foam... Tattoo is doing a seminar at national haunters convention showing how they did it!

So, Larry, where does one get a styrofoam sprayer, or can one hirea company?

I used a local insulation company with the big spray trucks, (the ones that spray into attics etc.) It was just easier and faster for me..

I second the spray foam insulation truck. He made short work out of it and did a great job. We used wood framing and stretched spandex to it and stapled it in place. Then he came in and shot the insulation on it. It worked great for us and the spray foam guy was very reasonable.
We did our waterfall and forest the same way. We took it out this year with plans on moving it and putting it back in and expanding it this summer.
DONT FORGET TO DROP YOUR SPRINKLER HEADS DOWN INTO THE CAVE BEFORE HE SPRAYS IT!

Another relatively cheap way to do it, though heavier and may not be quite as durable if customers have the chance of running full bore into it, is building the frame out of wood, then screwing up old scraps of carpet and coating it all in monster mud (paint and plaster mixture, add in some sawdust for extra texture) You do the mud in your darker color, then dry brush it with a lighter color and can look pretty good, even more so with creative lighting.

I did a giant stone cave entrance archway for a local play by doing this similar method with a wood and chicken wire frame, shaped the wire, then did monster mud with burlap almost like paper mache in technique. I opted for the burlap for the thinness as it had to be on wheels and moved on and off set. Once painted even in the bright stage lights it looked really good, and held up with no damage for an the entire 2 month run of the show.

Also, if going the spray route...especially if you are a bigger haunt, or want the freedom to work at your own pace and change as you go, and want to DIY it more... Smooth On makes a really nice Spray system that works on cartridges and can spray foam, silicone, plastics, and foam coatings. I think the initial system is around $800 and just needs a decent compressor to run it.

I know the crew from the Branson Zoo/Branson Haunted Adventure do the spray installations. Their work is phenomenal.

Here is my cave. I used chicken wire and pulled it in different directions to create the shape and used weed control cloth as a backer then sprayed the foam.

So how durable is your cave. I think it looks great. We did one out of 2x2 and chicken wire (as Larry posted), but we took burlap over the chicken wire and then took a drywall mud and paint mixture to coat it. Then we airbrushed over it and it seemed to work fine. The only thing that scared us was that it had kind of a flex to it. And thanks to us being outdoors and the rainy season we had this year, it needs to be redone. Is the spray foam idea pretty weather resilient? Anyway I was just wondering how durable your set was.

We were gonna build a cave this year using large styrofoam blocks.

I know a guy in the area that might be able to show us how to mix a hardcoat solution that we can FR.

Does anyone have any other recommendations on this? Use spray or other method?

Brad the spray foam insulation is fire retardant in itself but we coat it anyway for added security. For those of you with an outdoor attraction the spray foam has to be painted because the uv rays of the sun will deteriorate the foam. Once it was sprayed it set up and was very hard and solid. I think the spray foam is the way to go if you dont have access to a hard coat machine or hardeners.

Where r u getting the styrofoam blocks from?

There was a guy that did styrofoam work for all the movie companies filming in our area. He actually worked on some really big movie sets.

He sold his business, and dumped all his extra foam. We went dumpster diving for several days straight, and got a TON of foam!! More than we can deal with.

Thanks for the plug Tim!

Here are some photos of caverns, catacombs and caves we have created over the years.

We are teaching two scenic design seminars at NHC and MHC and will be covering these techniques as part of the classes.

We will be doing a small demo on caves as part of our seminar at NHC in Pa and a much larger demo at the MHC in Columbus.

One more.....

This scene was seventy feet long with a twisting and turning path.

Yep, TOF has to have THE most realistic cave set I have ever seen. I have toured a few real caves and the BAD BOYS really did an amazing job!

We built that cave 3years ago and half of it was out in the open, never had a problem. This last year we moved the haunt to a new location on the ranch and actually cut all supports to the cave and loaded it on a large trailer and moved it to the new location and didn't damage anything at all, it held its shape 100 % and now is freestanding.

I've looked into shotcrete and gunite but due to the cost of the equipment, that option is right out.

I've been doing some poking around about using a hopper gun to shoot cement, basically a poor mans shotcrete. Has anyone done anything similar?

Yes I use a hopper when I shoot acrylic stucco, thats what I coated my foam castle with.

It is awesome stuff. My castle has lasted 5 years and is still going strong. Here is a few shots on my photo bucket of me coating a few foam tomb stones with it. Also a shot of the bucket so you have the info. If you need their site here it is
