Patio using block paving

[dancooke]

hello again all, suns out so back in the garden back on the forum,just want to thank you all who helped last year on helping me complete 120m2 of driveway at the front of my house it looks great and seams to be holding out after a bloody cold winter,
now on to my next project,
i have a area at the back of my house that i wish to turn into a block paved patio,it is currently concreted and is a good 300mm below dpc,my question is ~is it possible to lay block paving on top of concrete by putting in an edging course on concrete and then setting the blocks into of fresh skim of concrete to permanently hold them the area is only 12m2,i dont want to take out the old base as it is tied in with the foundations
any comments taken on board
cheers all

the method you are describing sounds like rigid block paving, there should be a page on the website which would be worth a look pending the pros opinion

[dancooke]

cheers for that ,page found and has put my mind at ease proving it is possible

What do you mean by putting blocks on fresh skim of concrete..... You already have a concrete base

if the concrete is sound,crack free and clean then i guess a rigid construction would be OK
caveat emptor however!

If you use a cement:sand bedding mortar enhanced with Ronafix, and use a Ronafix:cement bonding primer on the concrete and the back of the blocks, they'll stay put despite traffic and weather.
