How can I put wood tiles or deck on slightly sloped concrete patio?

by JillSida
The large patio outside my condo has a slight slope to help with drainage but it's ugly and I want to put a wood deck or interlocking deck tiles over it. the concrete is in 6 large slabs that are separated by slim wooden separates. One of the slabs in visibly higher than the others. is there a way to do this or should I take all the concrete out and start over?
