recycled concrete patio--where do I start?
I'm a newbie, so just wanted to say hello, and glad I found you. I have a million questions so thank you in advance for any advice you might offer.
I'm interested in laying a recycled concrete patio, but I'm not sure where to start. I'm a single mom so my budget is tight, and I'm trying to use what I have in a creative way. I live on an acreage in the country (100 year old farmhouse) in a northern climate, so I need to worry about heaving during freeze/thaws. I currently have a large concrete floor and foundation on my property from an old farm building that came down in a storm--it has to be removed anyway--and my plan is to break the floor and foundation up into manageable pieces with a bobcat and then a sledgehammer (I have teenage sons) to use for the project. I also already have a 6-8 inch deep area of sand bordered with landscaping timbers with landscaping cloth underneath in the perfect spot and size for the patio--I had a very large above ground pool there during summers when my children were a little younger.
Will the old concrete be suitable for patio pavers? I have no idea how deep they would have poured it for a building floor vs. a sidewalk. If the concrete varies in thickness, how to I work around that--do I just build the sand up more or less under each piece to even them out? Is my sand too deep to lay pavers--will they sink in over time? Can I lay the pavers directly in the sand and fill in around them, or do I need another layer of something under them? What type of fill should I use between the pavers? (crushed limestone?) I like the look of plant material between the pavers, but with the sand base I don't think that will work, plus I live in a hot in the summer, dry climate--not sure if the plant material would live. I'm fairly experienced in diy projects, but this is a new area for me. My budget doesn't allow for me to purchase pavers--I need to replace my furnace this year too--so I thought I'd give this a try. I think the weathered concrete might be lovely behind my old farmhouse.
Any and all advice would be helpful. I've been looking all over the web for tutorials on this type of project, and there's not much out there. Thank you!
