paving over concrete question

[Mark CH]

Hi All,
We've got a concrete path that we want to pave over, however the paving will also extend past the edge of the path (about 1000mm) up to a retaining wall. Do I have to concrete the 'gap' where there is no concrete or can I just put a roadbase and sand base that is level with the path for the pavers to sit on? I'd rather not have to cut adn smash up all the path! Also, what is the best adhesive to use where the pavers are on the concrete?
Any advice would be much appreicated!
Cheerio,
Mark

I would just RB it if your not driving over it.

I would use sand/cement bedding under the pavers - dont use adhesive unless you cant get a 25mm min. bedding depth.

use the roadbase, mix a some cement though it (1 of cement to 6 roadbase), make things a bit more stable.

pavers on concrete, mortor base, (or, as I have seen done, silastic or liquad nails :)

Where is Planned Landscape when ya need some good solid advice ??

Just make sure not to vibrate plate it otherwise they will all crack. :)

I would be dowelling and extending the concrete, or your pavers will crack along the join between concrete and rock.

I'm here mate...was gonna say just PVA or clag? :2tsup:haha

No I would extend the concrete if paving on mortar- just get a couple of pre mix bags, or just roadbase if paving on sand. If concreting dowelling is an extra form of insurance against the outside strip of concrete sinking below the original slab and having the joints crack.

Don't laugh, my front steps I made using boral wall blocks (balmoral, sandstone) with matching colour 190 x 390 pavers as the tread, couple of tubes of silastic held them in place quite well, after all, it was only a temp solution. Almost 10 years later and I had a hell of a time getting the pavers unstuck from the wall blocks :-)

mixing some cement through the roadbase (crushed rock) is the cheap way, sort of depends on how big an area needs to be paved that is not on the concrete path I guess
