New patio advice please
Hi,
Not sure if this is the right place to post this but some advice would be greatly appreciated.
We have recently hired a local landscaper to lay 30sqm of indian Sandstone for a new patio in our new build garden (moved in Sept 2024). We have been very happy with their workmanship and work ethic thus far and while prepping the ground etc.
However I have gone out this morning to check the newly laid patio out (half of it was done yesterday morning, the other half on Friday). I have quickly noticed a number of loose slabs that I could easily lift by hand. A number of other slabs also sound hollow when tapped so I am sure they would also become loose with relative ease if I was to try lifting them.
This is clearly an issue with either the cement mixture being inadequate or the sandstone slabs not being prepped properly?
I am now a bit reluctant with them even with a fix as I suspect the entire patio will likely need re-laying, even the seemingly solid slabs? I am also unsure if this was just a fluke on their side (they are a very well reviewed small, local company).
I have messaged them this morning with these issues as they were due to return tomorrow to have the pointing done. Still waiting to hear back from them.
Any advice on how I should proceed from here would be greatly appreciated!
I have attached a couple of pictures with some of the loose slabs where you can see the back and the mortar bed.
