A: There are several ways to cover that slab, but I don't know if you would consider them uncomplicated or inexpensive.

First, it would be fine to pour new concrete over an existing patio as long as you have room under the doors and gates. You just need to apply epoxy over the top of the original patio to create a membrane between the two layers. Also, the new concrete should be made with a higher sack mix and some fiber additive.

Bert Roberts recommends, " Laying masonry products (thin or full size bricks, pavers, etc.) over concrete, again as long as you have enough room as described above to clear doors, gates and the weep screed. However, homeowners often suffer "sticker shock" from the price of masonry. So I recommend you check out the options and prices of brick and masonry available at a masonry or building supply store first. If you decide it's a look you want that will fit your budget, then you can contact licensed masonry contractors to get estimates for installing it for you."

Tom Milburn adds, "For about $5 a square foot, you could resurface your existing concrete with an overlay. We would apply a 1/2 inch epoxy rock overlay that is much denser, smoother and shinier than traditional exposed aggregate. It is available in a variety of colors and sizes to create multi-colored patios, borders, etc. Water runs through the top layer so there is never any standing water on the surface and it carries a 10-year warranty (and will last far longer with occasional resealing). We can also extend or make any necessary repairs to existing concrete before resurfacing."
