Hi,
I'm about to start construction on a new dirveway. At the entrance it has a sharp right turn then a sharp left (both extend over about 9m) followed by a 9m straight. the wife says that she wants concrete block pavers laid in a 1/2 stretcher bond arrangement. My question is that if I start this on the staright at 90 deg to the edge of the drive then as i work round the corner the bond will become parrallel to the drive and then return back to 90 deg. Is this acceptable as I thought that the blocks should always run at 90 deg to the direction of travel. If not, how do I go about turning the corner? the outer radius is 10m and the inner is 5m on both turns.

Yes I know that the stretcher bond is not normally recomended, but if you check out the marshalls cat, most of the block paving they do is shown in a stretcher formation of one kind or another -so it can't be that bad! her in doors doesn't want the herringbone layout that everyone else seems to have plus I don't think that that style is in keeping with older victorian houses ???

Here's a comment on that quote from HB&R - bollocks! I've forgotten more than they'll ever know about block paving. Which eejit came up with that nonsense? If it was a time-served paving contractor, I'd be appalled!
Where there are exaggerated forces on a segmental paving, a fully interlocked structure is required. Stretcher bond is not fully interlocked; herringbone is. The only way to create an interlocked stretcher bond is by using dentate blocks, where the shape of the block creates two vectors of interlock (three in some of the very latest blocks) despite the laying pattern being uni-directional.
However, if you want stretcher bond at your home, you can have stretcher bond. You can have basketweave, random, stackbond or whatever - it's YOUR property. While we might recommend a herringbone for trafficked areas, that's all it is - a recommendation, not a regulation.
In your scenario, I would suggest summat like this...
...which keeps the longest paving joint transverse to the direction of traffic, which is about the best you can do with a stretcherbond arrangement.

like i said ,marshalls show the majority of their wears in stretcher formation, in fact most of them will only go down in that way! so does that mean then that they are not suitable? my local shopping centre carpark is laid that way (marshalls drivesett traditional) as are the new sleepling policemen in my town centre (standard 200 x 100 concrete pavoirs) If its good enough for the biggest block paving manufacturer in the country then its good enough for me

You're not right to say that "most of them will only go down that way". Any rectangular block, by which I mean a block that has sides in a ratio other than 1:1, can be laid in a variety of patterns.
Further, it's highly unlikely that your local shopping centre carpark has been laid with Drivesett. These are only 50mm deep and unsuitable for commercial traffic. The car park will have been paved with Tegula, probably the 80mm version, which is often laid as transverse broken bond (stretcher course-ish) but can also be laid in a variety of other layouts, including a number of different herringbones.
Now, have you come into the Brew Cabin to pick a fight or were you actually looking for help? You seem to have completely disregarded my previous comments. If you mock time-served tradesmen and their wealth of experience, don't be surprised if they tell you to bugger off.

i've not come to pick a fight but when you tell me that I shouldn't use a stretcher bond on a driveway when i've actually seen it in use in various ways -drives ,roadways and carparks, then forgive me if I don't agree with what you are saying. As for mocking, when did I do that?
As for the carpark, I know what tegula looks like and it wasn't that. What ever it was it was laid out in straight lines made up of 3 different length blocks giving anything from no bond in places to 1/4, 1/3, and 1/2 bonds. From what you have been saying, this shouldn't have been the case. Now i may have this all wrong, but if there is a substantial restraint around the whole perifery of the drive, the blocks are laid hard up against each other, wackered down to refusal and then the joints fully filled with sand , where on earth can the blocks actually go once laid? it should not make a difference what pattern they are laid in
