I haven't had any experience of this particular company, pricewise they seem expensive. You will enjoy the look of the random mix of six. The largest size is the heaviest, but still manageable, when they deliver they can often put one box on top of another, making it awkward to unpack. A lot of reclaimed Yorkstone is available in the north of England. The man made Marshalls products come at a cheaper rate than natural stone.

They are expensive,lot of builders use them on up market properties due to the unavailability of local natural stones,if your having it done by a reputable groundwork company youve no worries,price apart,but if your doing it yourself bear in mind they are tremendously dense and hard and a stillsaw is needed.A way out of that is while following the pattern you could put dec.aggregate where cuts where needed.Of course that depends on your personal taste. If you do use them they look great.Look at your local builders merchant more than likely they stock them and alternatives.

If they are anywhere as heavy as those I am laying BA take your time and watch your back!

A good tip is to walk them into place avoiding a lot of carrying and if you follow the pattern that comes with them on the crate you don't need to cut. If you have to cut a normal angle grinder will do the job as the indian does not come in thick pieces,

Thanks for all the feedback. After a lifetime of lifting stupidly heavy stones in and out of the backs of cars I will be watching my back, Ian.
Cutting is not a worry as a friend recently lent me an angle grinder with a diamond blade to cut ceramic tiles - hot knife thro' butter - too easy. My main concern is dealing with the different thickness of the slabs however, I expect that I will resolve that, especially as I am not a perfectionist.
Unfortunately in the north of Scotland we have little choice of materials from the local suppliers so the internet is our best option. I am expecting that we will go with these slabs and will let you know how we get on.

Good luck with it then BA! :~))

Just be careful with the grinding of them,but you sound competent. I should have mentioned a diamond blade is so much easier,before delivery see if its possible for them put the paving to near to were you intend to .lay them without impacting your working area .A lot of suppliers will do that for you.
