At the end of October I had my patio laid in Indian stone. Now I've come to clean it after the winter I find most of the pointing between the stones has turned to loose sand. It's that soft a screwdriver can be easily pushed right through it.
I've phone the company who laid it, they blame the bad winter and accept no responsibility.
Can I ask the experts here:-
1) Is it normal or acceptable for the pointing to crumble to sand over one winter.
2) If I can't get the company to correct this I'm thinking of doing the work myself but need a few pointer.
If I power wash the old pointing out is this amount of water going between the stones likely to disturb the bedding of them?
Google'g re-pointing, a dry mix seems the favoured method but the recommended mix is anything from 1:1 to 8:1 and type of sand varies from plastering sand to sharp sand.
Advice on the mix and type of sand / cement would be appreciated, something which will not stain the Indian sandstone.
