I bought a new house nearly 3 years ago with 90m2 of indian sandstone paving, laid by the builder who did the house.
The pointing has nearly all fallen out and the stones are beginning to rock. It is unsightly.
It emerges the stones are laid on spots of cement. I have also been told the stones are upside down. There are big voids where the pointing has gone which communicate with the gaps underneath the spotted cement base. The stones are still flat, with adequate run off etc.
I want to repoint to make it look nice again, but have been told by a couple of contractors this is not possible with the base as it is, and I need to pay for new stones (because they are the wrong side up, with the chamfer reversed so there is a wide join) and a complete re-lay.
Clearly, this is extremely costly and wasteful.
Does anyone have any advice on whether my existing patio can be saved? Brushing something in is going to be difficult as it will just run away underneath the slabs into the voids caused by the 'spotted base'.
How important is it that the stones are the correct way up. If I got them completely relaid on a full mortar bed, albeit the wrong way up, would one of these geofix type products still manage to form solid pointing? At least this would save the cost of new stones....
