Pointing

[DNgroundworks]

Hi fellas been to look at a job this morning re-jointing about 200m of indian sandstone.

The original mix is very weak and as a result last years winter made a proper mess of it, anyway the problem is that the joints are unbeleivably wide up to 2.5 inches in places, what sort of mix would be best for this?

Easi point no good, ive found that it shrinks in large joints,

[lutonlagerlout]

any standard mortar is going to struggle in that size joint
65mm is more of an insert than a joint
really dont know how you could do this and guarantee your work
sorry

i guess the polymeric would work but wow you'd be talking thousands with such wide joints,

are the slabs laid well etc just massive gaps? relaying out of the question?

[DNgroundworks]

ye well laid, just like you say massive joints, relaying out of the question, having just spent over 20k on the work i doubt they will let me lift it!!

I wish they had contacted me about the work in the first place, theyve known about me all along, first thing they said when i turned up "they have done a bad job, wondering if you can sort it out?" lol

[lutonlagerlout]

got any pics?
it defies logic that you could lay injun stone with joints that size
I have seen it on yorkstone and there's a reason for that,but it still displeases me to look at
maybe a lime/cement/ sand mix knocked up and gunned in?
all bets are off with joints that size
or even pour liquid bitumen into the joints?

Sounds more like they are laid upside down.

I think triple L has cracked it with liquid bitumen.

Just a thought but maybe a grano mix with sbr would do it?

I re - pointed a yorkstone drive way about 5 years ago with similar size joints which had been badly installed. Ended up using a strong granno mix and its still holding up well. As mentioned i would add sbr. Not sure how granno would look aesthetically though against indian stone.

[seanandruby]

Maybe add a touch of colour. With such wide joints anything will look bodged, can only try. Just do a trial area first.

[DNgroundworks]

I was thinking a granno mix sean, not to sure how bitumen would look ive done it before on setts and i find that in a wide joint bitumen sticks to the side and you end up with a deep high sided U shaped joint if you get what i mean.

Ill try and get some pics but my internet is seriously shite.

There not upside lol i would of spotted that straight away.

Unless it leads to more and better work it might best to not take the job on. I wouldn't do it not worth it for the finished result.

Probably the best advice.

Work is work in the present climes ???

Work is work in the present climes ???

Yep and we are quiet, and i think there might be a possibility of further work as there house is newish and the garden smart but there driveway is nackerd and very big.......

The guy is pretty clued up and is aware that the joints are to big ill just explain that i will use a stronger more substantial mix, but i am not prepared to guarantee the work as i didnt undertake the project in the first place.
