Hi all,

I'm new to this forum but have been a regular visitor over the years to Pavingexpert.

We moved into this property a year ago and the patio looked ok, over the year it has deteriorated as we have dog so we try and wash it as often as possible.
It appears to slope towards the house and is just laid on sand. The gaps range from 0mm to 30mm and some of them are the wrong way up, as the chamfer is at the top.

My plan is to relay this but I'm not sure what kind of base this will this type of stone will require. We will be reusing the stone which I think is natural Yorkshire Stone.
When we take it up we'll be power washing each of the slabs.

I was thinking about laying this on a MOT 1 sub-base and then onto a layer of cement.

Is the MOT 1 sub-base overkill?
What size gaps should this kind of paving have?

Any advice would be appreciated.
This is my new plan for the garden as we want some lawn for the little one to play on in the summer.

Thanks

Michael

looks like indian stone to me?
yes 100 mm of type 1 then a 40-60 mm bedding layer 6:1 grit sand cement
falls to a new lineal drain going to a soakaway

Thats great, thanks for the information. What size gap should be left between the stones?

10mm is a good size to aim for. You'll find it hard to get a solid mortar joint of any less than 10mm if using traditional mortar.

When working with uncalibrated stone small variations in size of flags can throw you out of alignment. have a look at the laying sandstone flags page on the main site there is a good guide to balancing joints.

I'm not completely sure that is *is* Indian, LLL.

Some of those pieces are definitely not orthogonal, and the one thing about importaed stone is that it's nearly always bang-on 90Â° corners. Obviously, sopme of them may have been cut when originally laid, but then looking at one of the photies, I'm struggling to identify a set of modular sizes, and that's the other think the Indians always produce: modular sizes.

It could well be odd-and-sods of yorkstone, trimmed to suit the site.

However, none of this changes your very good advice. Some of the stone may need trimming to maintain that ideal 10mm joint, and with the rest of it having fettled arrisses, it might be worth nobbling any sawn pieces to maintain the look (like this)

maybe it is!
just those pink ones look like modak rose to me?
I have laid the pure shite stone that mick saw in india,you know when people buy it from a garden centre or off some random ebay shop
and the sizing was non existant
just a crate full of random sizes
back to the OP
how thick is the stone?

Also, the flags that have been laid upside down will be mortar stained and will be unusable.

Thanks some great advice there and lots to read.

The stone seems to vary in thickness going from 25mm up to 40mm. The modular sizes seems to be pretty consistent when measuring a few of them.

Having turned quite a few over there doesn't appear to be any staining.I think that's because they have just been laid on sand.
we'll have to look at each one carefully when lifting it up.

Thanks for the advice guys.

One further question for you guys, would you run a linear drain all the way around the edge, or just the main patio part?

If you can't fall the paving towards the planter beds for drainage, then I'd just use a linear channel along the lowest edge, wherever that might be.
