    Have a customer that requested her cement patio be covered with pavestones - anyone ever put them down on cement? If so, what process did you use.

    If the slab is in tact - just put your edging down and 1" sand and install like normal.

    would have never thought to put the sand on the slab - good tip.

    I am in no way an expert on pavers, however, wouldn't the winter possibly heave the slab during the winter and cause havoc with the pavers requiring you to readjust them every spring? I like the idea of removing the slab and placing down the proper sub-base. Also, try the ICPI website at for information.

    You can cement them with pure portlan on concrete after a good wash with a muriatic acid mix. Hw high will it be though? If u use the 1/2" thin brick and add 1/4" for the morter it may be pritty high

    I've done pavers on top of porch slabs all the time. As long as the slab is in good shape do not even bother using sand. We glue our boarder pavers down with landscape glue.

    I do the same thing as Matt. We glue the borders to the slab, lay our field and sweep with polymeric sand. We use the polymeric because when you mist the sand per installation instructions, it hardens and eliminates the wobbling you get from the uneven surface.

    We have been bonding brick to concrete for years, someone here mentioned about a border stone then laying an inch or so of sand. This is ideal especially when your top porch isn't perfectly level. Its kind of hard to see but this is what we did here for the top three steps.
