I HAVE A PATIO AREA LAYED WITH IMPERIAL 2'X2'X2" CONCRETE FLAGS. THE AREA IS 22 SQ MTRS. THE PATIO IS LEVEL AND SOLID, BUT THE FLAGS LACK CHARACTER. IS THERE ANY WAY I CAN LAY NEW MARSHALLS HERITAGE PAVING DIRECTLY ON TOP, OR SHOULD I EMBARK ON A PROPER JOB, TAKE THEM UP AND LAY A SCREED BED.

Best take up the old stuff, Dave and start afresh. You may compromise the clearance to dpc if you overlay the existing - Heritage ar 40mm thick, plus another, say, 40mm for the bed, that's 80mm - how far below the dpc is the existing patio?
There's a page in the Block Paving section of the main site that deals with laying over existing. Have a read of that as it helps explain the problem with levels and thresholds.
PS - knock off Caps Lock when you type. Using all capitals is the 'net equivalent of SHOUTING! :)

Thanks for the prompt reply to my question. Now I know to take up the old flags, I will soon be making a start, and will no doubt be in touch if I encounter any problems.
PS sorry for shouting.

That's what I'm here for, Dave! :)
Not been up to Rochdale for a while - has it thawed out yet? ;)

I have an existing front patio of 3x2 ,2x2 concrete slabs approx 50sq mtrs.It seems very solid and has been here since we moved in 8yrs ago.
We would like to put a more decorative patio (possibly Indian or York) down on top and dont know if it is OK to do this, if so, I would like to know what I bed it down with,IE,does it need to be onto mortar,or is a bed of sand sufficient.There is one open edge which I understand would need setts.
Any advice welcome.

RTFM!!
in a word, no, alan
if you read the above section carefully you will see why
and no where on the main site does it advocate laying flags on sand

Have a look at Patio Overlay systems, the R2 Patio overlay system has been reviewed on this site and given a good report

are you connected to the R2 system Richard?
I asked the gaffer about this system and its potential uses for temporary paving a while back ,but he said he was having trouble contacting R2
so we used something else

ahh cool richard
we were doing a balcony and the client wanted slabs, but after talking to building control they ended up with promenade tiles
will bear your system in mind for future reference
cheers LLL
