Help! Wet or Dry bulk ready-mix cement. in House Renovations Posted May 20, 2015 Thanks for all the advice and replies folks!Apologies for not making my post clearer! It is plain to see that I am not a builder!I need to lay a floor that is either chaux mortar or concrete (béton). The option for chaux is to buy bags of lime and a load of sand, hire a large mixer, mix it on site, barrow it in to the cave to lay and spread it. I was under the misapprehension that pre-mixed chaux mortar could be bought in bulk. Apparently this is not the case. Mixing on site is also an option with dry ready mixed sand and cement that can be purchased by the cubic metre and loaded on the back of a truck. The other option is to purchase ready mixed wet concrete. This would have to be loaded on the back of my friends truck, 0.5 cubic meter at a time, driven 3 kms and dropped just in front of my cave onto a tarpaulin where it would be shovelled into wheelbarrows by two or three of us and then barrowed into the cave, (a distance of approx 8 meters), dropped in place, spread and levelled off. It should take about six loads from the builders merchant to complete the work.I need to add that my cave is not a cellar. It is a 8m x 4.5m room straight into the hillside rock with a barn door. (Caves such as these are in abundance in this part of France.) However I do not have room (or the funds!) for a cement mixer lorry with a 'tapis' to get onto the property, hence the need for mixing or delivery on site with a smaller vehicle.I am inclined to go with the wet ready-mixed concrete version as there should be 4-6 of us to do the work and I am advised that there is a working time of at least 30 mins before the concrete starts to go off. (The journey time from the builders merchants to my house is 4-5 minutes) .Also the work should be done in one day. Using dry materials will take two or three days, and as I am paying a couple of guys for their labour, keeping within budget is important. Thanks again for your replies.
