Hi I’m living on my own and I have recently had patio slabs laid by a builder. There is quite a large surface area laid and I have counted 21 slabs that can be lifted after being laid. Builder flattened the ground with a Wacker plate and laid slabs on a wet mix. The slabs are not rocking but are loose and can be lifted. He has started jointing the slabs but I have asked him of his plans for fixing the loose slabs and he said that he is using glue. He hasn’t used a SBR adhesive. Am I right in asking him to lift the old mortar bed out and relay or will an adhesive work. I checked the one he said he has glued and it can still be lifted. I’m just worried with the amount of slabs that haven’t been laid securely to the mortar bed. Thankfully I haven’t paid the builder. Any advice appreciated as I am a female and want to make sure I have all facts before speaking to him.
