Thanks Tony. I've no doubting that re-laying is the preferred option. But there is no way I'm having the contractor back to break out and re-lay 120m^2 of flags and risk ruining my slightly newer tarmac drive and lawn.
There is also no doubting you knowledge and experience, and I really appreciate your advice. But I have to look for an alternative. My day job for the last 20+ years is designing new products. 9-5pm I'm paid to find innovative solutions to problems. I don't always get it right, but I've a dozen or so patents to my name (I'm not bragging - its something that comes with the territory). My boss always tells me 'if we always do what we always did, we'd always get what we always got'. It's true that if the human race didn't look for new solutions we'd still be living in caves. So, after looking at various options, my plan at the minute is to lift the flags one by one, vacuum the area (yes you did read that right!), outdoor PVA the underside of the flag and the top side of the bedding, leave to dry and after consulting the company involved then use this adhesive:
Power grab n bond
Then re-point with one of the resin systems but I will make sure it is tooled in and compressed. It won't be particularly cheap (or quick!), but hopefully a lot less mess than doing it the more traditional way. The original contractor is coming back at the end of the week to have a look at the problem. I'll see what he offers first before I spill my beans. If I do go-ahead I'll be sure to report back my findings. If it doesn't work out you can tell me 'I told you so'!
