I work for a PVC, TPO, and EPDM roofing membrane manufacturer. 10x20 would be 2 squares of product. We sell it to the customer for way less than $100. I have to confirm the price because I work with specifications and details. I know we have 45 and 60 mil TPO and PVC, and up to 90 mil EPDM. They should not cost more than $30 or so per square. Then all I need is to get a heat welder and some products (maybe fesco or iso insulation) to make the sides. But then... we dont really have water disposal laws here.
Kapinn - there's you a business idea. Using EPDM or one of the plastics should work perfectly for different applications. My dad brought me a chunk of EPDM from Texas last year and we made a "rough" set of corners with side props using round hard foam insulation you can find at HDepot or Lowes, we used it as a "catch" in my shop. Then we simply dumped it outside. It worked "okay", but needed refinement. EPDM is "heavy" and not for mobile use, one of the lighter plastics should work well for mobile. I was planning on making one using EPDM and with fittings and a way to get the water out through a small pump or gravity feed. I bet with some ingenuity someone could come up with a better, cheaper model for both mobile and for stationary shop work.
