Hi,

Been browsing the site in anticipation of my first paving DIY job.

After much research my wife wants to use yellow granite cobble. I'm OK with this but I've been told numerous time that this is very expensive.

So we settled on mixed sized granite slabs, but using some small areas of cobble here and there.

Here is a rough graphic of the plan. Basically, the curved path from the front and the semi circle near the house is all I am concerned with at the moment. It is approx 30m2.

I was wondering if anybody had guideline prices/ratios on grouting flags vs cobble? I will be doing it myself so I don't care about the labour differences.

I can get the flags for approx 50euro/m2 and the cobble is about 60-65. I'm OK with that price difference.

What I need help on is how much more is all the "grouting". I'm guessing this will be the major price impact.

If it's not too expensive then I might just do it all in cobble.

So if you had 10sqm of flags and 10 sqm of cobble, what would be the difference in grouting costs????

Thanks!

using romex you would get 1.5 m2 at 12 to 15 mm joints 25 mm deep thats the d1 which is 25kg romex easy one of the other boys may know or you can divide cheers cookie :;):

A lot will depend on what you want to point them with,a slurry sand and cement mix for example would be no real difference but if you use a polymeric bases jointing medium such as romex, gtfk, instamac etc then there will be a big difference as there are more and deeper joints with sets. Also you can point and strike rd each sett which again will increase the cost. Cookie is the man for exact info on the subject, I personally would go for sets. Our drive 400m+ is in large cobbles/sets love them.

Cookie beat me to it haha

it all depends on what you mean by cobble .if they are fine picked setts then you could use a belt cleaner on them which is a quick way of grouting and a clean finish .(we use easipoint granatech ,which we use on granite sett speed tables in central london .grout is extremely strong and you can imagine how much traffic goes over them and i can honestly say i cant remember any speed tables or granite sett roads that we have constructed were the grout has failed .the main street of china town is an example of excellent sett laying ,still perfectly intact after 3 years of having delivery wagons driving over it everyday (john moss of brentwood sett layer )done it.flow grout is probably better for you as yours is a more domestic job .the better the grout the stronger it sucks to the sett in theory

How much extra for cobble?
