Our company has had this Big Tex 50LA flatbed since it was new. We use it all the time and it has paid for itself over many times. As it is stored outdoors in the elements and uncovered, the decking (unsure of wood species) took a beating and finally deteriorated to the point of being unsafe to carry loads anymore. The job fell on me to replace the deck so I brainstormed a while and decided it needed a deck that could withstand moisture etc. Trex (commonly used for outdoor decks) immediately came to mind. After discovering the Trex was only 1" thick I realized I would need another 5/8" worth of decking to fill in the U channel at the front and back of the trailer. I decided to go overboard to make sure the plywood also would resist the moisture and such. I rolled 3 coats of Mapai Aqua Defense waterproofing membrane to both sides of the CDX plywood. That product is commonly used in showers to waterproof cement board before tile installations. Once the plywood was secured and siliconed around the perimeter I installed the Trex planks with galvanized hardware and recessed the bolts below the surface. Glad the project went well and I'm pleased with how it came out. I feel confident this product will outlast the materials used prior. It had better we spent more than we really should have to do this. Oh well it's done!
