I need suggestions for floor covering for a wheel chair ramp. Ramp is 40" wide x 28ft long. The slope is 1 to 7.63. There are NO local code issues. I live in the boonies, no codes apply out here. There may be insurance issues but I'll deal with those later. I was handed a raw deal... build a functional ramp in less than 2 weeks while dealing with the aftermath of a flood in the house. Easy solutions suggested locally are 1) Rhino Lining - Same paint used on truck beds. Exactly what makes it "non-skid"? 2)Rolled Roofing - It comes in 36" widths. Basically I'm looking for a non-skid surface for the ramp. This is the only reason for my post... I'll deal with any other issues at a later date. I just need something functional for the short term.
