Hello,
I am currently having a patio and path laid with Marshalls Firedstone slabs and some of the slabs are getting damp stains on corners and a dot in the middle. The landscaper has told me he has laid the slabs on a full concrete base, as per his quote. I think he puts a layer of mix around the outer edge and then 5 dots. Is this common practice? What is a full concrete base?
It has been down for 3 days which have been dry and quite warm. They are not all stuck down yet and are yet to be pointed.
Can anymore advise me on what has happened? Should I wait longer to see if they dry out? Should I hold off having the others put down in the same way? Would the damp marks go if the slabs were pointed? He has suggested a sealant, but would that fix it? I am unsure what to do, as the job is half done. How should I proceed? I've attached some pictures and would value any opinions? Is there anyone else I could ask? Would Marshalls be worth a try, in case the slab is at fault?
Thanks[
