Indian Flagstones are loose

Anonymous user 01/03/2024 - 3.00 PM

Would appreciate any help, in November 2022 we had Indian Flagstone laid, with a Resin grout. After it was installed it rained for about a week, and the resin grout hadn’t set- we spoke to the installer and he assured us that it would set and it did. But after the recent cold snap, all the flags are loose and the grout is soft and coming away. Typically, thought we were buying from a reputable tradesman with plenty of 5 star reviews but now he is unresponsive. What’s the best course of action? How much is it likely to cost to rectify the problem? Could it be as simple as more cement and fresh grout? I can’t say what was used, it was done during the day whilst I was at work. Appreciate the feedback, unfortunately for us the tradesman is ignoring us as he probably realises the cost implications.

Are you a tradesperson and able to answer this question?

Hard to say without a professional seeing it, but sounds like it would have to be a rip up and relay job, cost is dependant on size and what needs doing and if able to re use existing slabs

Sounds like it needs to be relaid I'm afraid. Typically you'd be expected to lay any natural stone with an SBR slurry applied to the bottom of the slabs with a wet mix of sand and cement. Was this used during the application?

Hi Connor this can sometime happen to people if they didn't lay the flagstone with primer and on a full bed of cement this can be easy to fix as long as they have been laid probably on a full bed of muck you can pull them up and stick then back down with some primer (providing it was done correctly) and it shouldn't cost you much to fix either as depending on the size it's only labour and a couple of tubs of primer I hope this helps

Sounds like water has got through the permable jointing compound and frost has popped the slab off the mortar bed, the laying bed needs to be a full bed of mortar 5 to 1 sharp sand cement , the back of the slabs primed , could've a complete relay sorry

It sounds like the Indian sandstone wasn’t laid on a full bed of sand and cement mortar (not a spot bed!)and had no sbr slurry on the back of the paving for extra adhesion. The resin jointing compound(likely easyjoint) needs to be pushed deep into the joints with a trowel or similar so it hardens properly, not just swept and hosed in like many seem to do. Unfortunately the best course of action would be to lift and relay.
