Fair play, great videos. I've looked at a few of the older ones too. Presumably the flow point is non permeable as your mortar is bed on concrete. I've got Indian sandstone with 'easy joint' that is not appropriate for a non permeable base. So I'm thinking of using Flow Point on my slabs, same for a small section of old rustic slate (odd sizes & shapes). Do you think flow point is suitable given there are undulations in both materials? Presumably so, if flopwoint is used on cobbles? Just a little worried obout any water settling but there is a fall in both....
Hello, the Flowpoint will be suitable for your job. It isn't permeable so they'll need to be somewhere for the water to go but if you have a fall it'll be fine. If there's anything else you can get me on 07388 198476. Thanks. Michael
Hi, thanks for the video. Great work. What was the mix that you poured on at the end? and how long would you wait before hosing it away to clean it off the cobbles? thanks
Hello, the grouting compound we use at the end to fill the joints is called Flowpoint, there's more information on the website about how to use it. It's a cement based slurry and is rapid setting so depending on the time of year it can take anywhere between 10 minutes or an hour to cure. It setts like concrete!! really robust.
We normally lay the setts on about 70mm of 5 parts grit sand to one part cement. The depth varies depending on the ground but normally about 100mm. Thanks
@@mikefish7779 Hi Mike. What is the ratio please?. Is that 2x sharp sand 3x grit 1 cement 5:1 Or can I buy grit sand as a bulk bag from merchant. I’m building a driveway. Excavated 250mm down Was going to do. 150mm mot 50mm bedding 50mm cobble Bedding being 4:1 4x sharp sand 1x cement. What do you recommend?
Hi, doing a driveway too. What did you do in the end? I'm think of a having a setts at the front edge of the drive and was thinking 75mm mot, 100 concrete at the base for this edge. Did yours work out OK? Thanks
