I have a large patio with multi size paving slabs. It was probably not laid on the best foundation ever and all the joints have some minor cracking but some have, over time, collapsed.
I have a number to re fill. The size of the gaps is about 40mm wide and 50 mm deep. The existing joints are buff in colour.
I want to use a ready mix product (I realise that may be more expensive than mixing my own but I am not good at getting mixes correct.
I think that I need a ready mix concrete or cement (buff colour) and best in a tub as in the past bags I have used have split in transport.
Is there any product that someone can recommend?
Thanks
