Laying stone patio on separate beds?

[loply]

Hi folks,

I'm preparing to lay a natural stone patio approx 30sqm, foot traffic only, part of it involves a 4m wide circle feature which is going to take 12 weeks as it has to be manufactured.

I'm considering laying the 'rest' of the patio anyway, stopping a couple feet short of the circle, just to get it done.

Is it going to cause a problem though, because the patio will be laid on two separate beds 12 weeks apart? Thinking about the beds not being stuck together, potentially leading to differential movement?

I'm planning on using an SBR mortar mix for the bed, I was thinking I could leave a load of stainless wall ties sticking out to help tie the two beds together, but I'd hate for that to become a cracking point...

The sub base is about 35mm of new hardcore laid on top of old hardcore (from a 50 year old patio), then about 50mm of SBR mortar.

Thanks for any input.

Rich

there will be noproblem. cold joints like that are found in nearly every largeish patio anyway as its laid over a few days. No need for wall ties
