You are a crazy man doing this with wheelbarrows. Do you have a guy that will be spreading and getting it close while others bring the mud back? If all of you are just wheeling mud and dumping it, it will make for more work.
Any tips for me if it rainwhile were pouring? was just going to nail up plastic tarp to the side of the house and let it hang over the slab that way there's a slope for water to roll off to the side and onto the ground. Hope water won't seep thru the forms. Thanks!
Hopefully you can get it finished before the rain then you can just tarp it. If it starts pouring before your mud shows up I would call and cancel if they let you. I would keep tarps or plastic nearby and try and keep the water off of it. Once it sets off it won't hurt it to get wet but you don't want a steady stream to hit it and wash away the fines. Don't worry about water in the forms. It really only ruins the finish so protect that the best you can. Concrete sets off by chemical reaction so it will set up under water no problem.
Went online and some website call for a 30% chance of rain while other said 0%...Shrug. Got two bundles of tarp at the ready in case it does rain. So friggin nervous just about now, not about the potential rain but the pour itself.
Thanks for the encouraging words guys. Pics to follow. No selfie today my precious is at the office
