Mulberry View Posted April 11, 2023 Share Posted April 11, 2023 I know there are loads of different approaches to grouting Beam & Block. The one I like the most uses a strong but custard-like pourable consistency mixture of around 2:1 Sand/Cement squeegeed/brushed in. But where to start with sand and cement quantities?! I've got about 110m2 of floor area to do, with the fortunate benefit of them being in 3 distinct and separate zones. To note - the infill is all done, including the double/triple beams, so this is purely for grout. Link to comment Share on other sites More sharing options...
Temp Posted April 11, 2023 Share Posted April 11, 2023 Perhaps make up a small batch from bagged materials and see how much area it covers, then you know how much to order for the rest. 1 Link to comment Share on other sites More sharing options...

Mr Punter Posted April 11, 2023 Share Posted April 11, 2023 Sharp sand makes the job hard work. Building sand:cement 3:1 with plasticiser and sloppy. It wont take that much. It is easier when the blocks are wet. 1 Link to comment Share on other sites More sharing options...
Conor Posted April 11, 2023 Share Posted April 11, 2023 We did our precast slab grouting whenever there was a bit of cement or fine concrete going to waste. Took a few goes but by the end it was done and didn't cost me a penny. 1 Link to comment Share on other sites More sharing options...

See, I feel like it'd be worthwhile to fix everything in place. There is no detectable movement in my floor, but some of the blocks still wriggle a bit. Grouting will stop all movement, won't it?

As others have said above my builders just used whatever was leftover at the end of the day, watered it down chucked it on the floor and brushed it across the blocks (FOC). Many months later I needed to move a soil pipe only a couple of blocks across from where it was originally placed , ended up having to destroy the blocks with a kango and lump hammer to get them out . 1 Link to comment Share on other sites More sharing options...
