Lee4, look at C-gear. This is the flooring the US defense forces use on the ground prior to landing helicopters. It is a one-way mat. Sand goes down but not up.

Aldi currently have caravan matting on special for about $39 I think....looks the same as the stuff BCF sell. At our local store there were about 10 of them left.
Good Luck.
And another vote for the CGear mat. They aren't cheap but ours looks basically like new after years of use. It stays clean and the sand and rain just drop through it. We tried shadecloth prior to getting it and found it got slippery when wet, after slipping on it and falling we got rid of it. CGear gives a much better grip even when wet.
