Hello, I'm a Canadian working on a construction project in Jamaica. We are resurfacing a rooftop concrete tennis court that is approximately 120Feet X 60Feet. The original surface is flat and so water is collecting in spots and leaks into the condominiums below. We are looking for a tennis court resurfacing material that would make the roof waterproof, and allow us to slope it slightly so the rain water runs off. Do you think your product would achieve this result? How thick would it need to be? how much would I need? do you also sell the binding agent and if so how much binder would I need and what would be the cost of all of this, to Montego Bay, Jamaica. Since I do not know the quantity required, the amount entered is merely a guess. I am estimating that we require the surface to be 1 inch thick, but I require your expertise to clarify this amount.
