As a last resort, leave it in the barrow. Oh yes, I have added approx 10% (as I can’t afford to be short) and have a space for it, and washout 👍 1 Link to comment Share on other sites More sharing options...

joe90 Posted June 29, 2023 Author Share Posted June 29, 2023 6m x 4mx 150mm thick = 3.6 cu m + 10% = 3.96 cu m (ordering 4 cu m) 🤔 1 Link to comment Share on other sites More sharing options...
saveasteading Posted June 29, 2023 Share Posted June 29, 2023 If you haven't done so, put either a long timber and level across various angles and measure down. OR a very tight line. And average. 0.4m3 is quite a lot of spare. But yes better too much than too little. Link to comment Share on other sites More sharing options...
joe90 Posted June 29, 2023 Author Share Posted June 29, 2023 Oh yes, long timber across shuttering (which will be used fir tamping). Fairly flat. 36 minutes ago, saveasteading said: 0.4m3 is quite a lot of spare. But yes better too much than too little. It only comes in half meter load sizes and I can afford to be short.

You might have a lot of concrete for your gnome moulds. 1 Link to comment Share on other sites More sharing options...
Pocster Posted June 29, 2023 Share Posted June 29, 2023 My solution to excess concrete was to dump it down the sides of a underground house 😁 Link to comment Share on other sites More sharing options...
joe90 Posted June 29, 2023 Author Share Posted June 29, 2023 The sub base was a car park for 10 years and very compact so minimal movement there I guess, sand compressed a fair bit. I am tempted to tread the rebar mesh in after tamping as it being down on chairs (bricks) makes getting on it difficult 🤔. I do have paths that need repairing so might dig them out ready, I can always mix concrete afterwards if none left over. Link to comment Share on other sites More sharing options...

saveasteading Posted June 29, 2023 Share Posted June 29, 2023 Have you thought about fibre additive instead of steel reinforcing mesh? It will save you a fair amount of money and hassle. Add £30 for it in the mix and deduct the steel and spacers. Link to comment Share on other sites More sharing options...

joe90 Posted July 5, 2023 Author Share Posted July 5, 2023 Already for concrete being delivered in the morning. I roped my daughters boyfriend and his mate to shovel it for me whilst I “project manage “ (make the tea) and trowel it off with an “easy trowel” on a long pole. 4 Link to comment Share on other sites More sharing options...

joe90 Posted July 6, 2023 Author Share Posted July 6, 2023 No time to arrange time lapse photo because concrete arrived an hour early 🤯, still down and tamped, just waiting for the bleed water to evaporate and get on it with an easy float. 2 Link to comment Share on other sites More sharing options...
joe90 Posted July 6, 2023 Author Share Posted July 6, 2023 The easy float does a good job, still trowelling away ….. 1 Link to comment Share on other sites More sharing options...
saveasteading Posted July 6, 2023 Share Posted July 6, 2023 You were lucky getting it early. That should be stiffening up nicely by now. Don't overdo the floating or you will get too much cement paste. Link to comment Share on other sites More sharing options...

joe90 Posted July 6, 2023 Author Share Posted July 6, 2023 (edited) Yes large tarp ready, finish is not quite as good as I would have liked or did before with a power float but it’s only a garage, mistake I did make was bringing the dpc up and over the shuttering so unable to get my edging trowel around the edge. I have a concrete grinder disc fir my angle grinder so can always tidy it after it’s set hard.

joe90 Posted July 12, 2023 Author Share Posted July 12, 2023 After uncovering and removing the shuttering, the answer to this OP is. YES. I should have power floated the slab. It’s very flat but the surface is not what I wanted (yes I can be OCD ) it’s only a garage and I will be painting it I guess but hey it’s too late now. Thanks everyone for their input. 🤷♂️ Link to comment Share on other sites More sharing options...
SteamyTea Posted July 12, 2023 Share Posted July 12, 2023 Can you cover it in rubber. Makes for a nice kneeling surface and can usually be washed down. Link to comment Share on other sites More sharing options...

Don’t tell @pocster that, no, it will be fine, I do have rubber matting to go by the bench to stand on, ex high voltage rubber matting 10mm thick 👍.
