I am hoping to buy the sandstone setts in the link above. They are a good price and local to me. However, the guy selling them says they need to be bedded on sand and cement screed.

Is this correct ?

I am doing it for my drive, so it will have a car on there.

I have done one block paved drive before and this was using sharp sand and marshalls Tegular block. It was pretty straight forward.

I just don't think i can do a wet screed and point up the blocks individually. It would take a lot more time i think.

So does anyone know if i can use sandstone block in the link above with a flexible bed and brushed in paving sand for the joints ?

yes they need to be laid the same as setts
100mm bed of 6:1
and a bond bridge

Ok, so a bit disappointing.

Is the mix of 6:1 like a brick mortar in consistency or does it need to be drier ?

What is a bond bridge ?

Also how do you point these blocks as you lay them ?

Do you wait until the next day and then do the pointing ?

Ok, i have had a chat with a mate and laying these sandstone blocks is pretty straight forward and i have actually done similar before, but with paving. Just wasn't sure about this system using these blocks.

So i am going to be using them later this autumn. Got the drive dug out now, but need to finish my extension this summer first.

What is the best pointing method to use with these blocks though. Can anyone help me with this one.

I was thinking about making my own dry mix using kiln sand and cement. Would this be ok ?

Or would it be better to get one of these resin wet systems. Any recommends on these products ?

Right i understand my options.

1) polymeric jointing with the pre bought brush in mortar or

2) The resin slurry option.

My area is a drive with one car parked on there. So based on what i have read the slurry option is a stronger and longer lasting product. It also looks fun to apply.

Would you guys say this type of product was ok for a natural sandstone block with cut edges ? Would i get a lot of staining on the actual block or will the excess just brush off easily ?

Thanks for your help.

hi there
gftk vdw 815 I have had great success with
depending on your joint width think this goes down to 3mm but i prefer 7mm minimum
needs lots of water and lots of brushing
plus a paddle drill to knock it up

Ok thanks, i will look into it.

I like the idea of a 10mm joint width.

Just seen this site and they do some lovely block paving in the material i want to use.

They also use the system you recommend so i am happy it won't stain the sandstone.
