I've had a browse through previous posts to see if been raised before, but not found.
Client wants to replace old concrete flag patio with Stonemarket pavers, 50mm. Patio only, no vehicle traffic.
Started lifting old flags, uncovered a 150mm raft concrete underneath, on which the flags had been laid using the old 5 spot method. Leaves about 80mm depth between concrete raft and top level.
Reckon I don't want to lift the concrete, as in good nick, it's level, and who knows what horrors lurk underneath. So propose to switch from a flexi sand base to a rigid bed using standard mortar mix, going for a full mortar bed lay as per flags.
That would mean that I'd need to mortar point as well to waterproof it all.
Is this right? Or do I have other viable options?
Cheers for any advice.
