Replacing Wood Decking, Any suggestions?

Pave stone is cheaper than concrete and can be bought at most home stores. You can get unskilled workers to demo the old deck and prep the area. After removing the old deck, remove enough soil to be 2 inches below the surrounding area. Fill this with sand, then lay the concrete "pavers" over the sand,using spacers. cover them with sand, then wash it off. The sand will fill in between the stones . You can get them in the pebble finish in either 12 or 18 inch squares as well as rectangles and some shapes. Many are interlocking and can be quite attractive. They allow water to get back into the soil and are easy to remove and replace. When you pick them up remember they are concrete and heavy, so don't overload and be willing to make several trips or have then delivered. Sand for an area this size should be delivered and shouldn't cost more than $100. and will be more than you can use, but it is worth it not to have to try to handle sacks and pay more than that for the sand you need.
