  1. rrmccabe I was actually planning on just filling the footing flush with the rest of the patio. The existing patio is 20 plus years old and I live in Memphis TN so it does not get that cold, if they move will they not just move together? Is it not okay if the footing and the existing patio bond together? I guess I could make a square form out of 1/2" material and pull it out after a few hours? Then I could fill the joint with driveway caulking or something? I was not concerned with the heaving until you mentioned it.
  2. Two of them will be only 18" from the edge of the patio, but the other two will be about 14' from the edge. The patio is attached to the house, so when you walk out of the house there is patio for 14' and then the edge. I see where you are going with this I think, just dig under the patio from the side and pour concrete under it. If it was not for the two closest to the house that is what I would do. Thanks -Nic
  3. Looks like I can rent a gas powered concrete saw 14" from Home Depot for $72. For one day. I only have 12' to cut or 4 12X12" holes. I have never used one so I am sure it will take me all day. I am glad to pay the $72 to keep my frustrations to a minimum which might not be the case when trying to use a grinder. Here is the pic from their website, With that 14" blade all I will need to do is lower it into the slab and pick it back up I imagine, Guess it wont hurt if the holes are 14"X14"
  4. This would prob work perfectly, home depot rents them too. But they do not have the larger model available in my area. The smaller one will do 6" diameter and the big one will do 15".
  5. Well the point in getting a clean line is to keep the project clean looking, since the new concrete will not match exactly, I am going to bring the footing up fluch with the rest of the patio concrete. If I was not worried about looks I would just use the sledge, but my main goal is to prevent any of the existing patio from cracking.
  6. Thank you everyone for all of your comments, I should have been more clear. This patio will have 6 posts, four of which will be on the existing concrete patio which is prob 4" deep, perhaps more perhaps less. When I went to get a permit I was told the footings had to be a minimum of 12" deep. One of the posters mentioned "why not just put the post on top of the existing patio? That was my original idea too. But the permit guy told me I couldn't do that, and it will prob be safer to have a nice deep footing anyway, I actually plan to dig down 24". My location is Memphis TN, so frost heave is prob not a issue at 12" to 24" deep footings. I have never had to cut concrete and end up with nice edges. All I have is wood working tools and I do not want to use them on the concrete. I like the angle grinder idea and the skill saw idea. With the diamond blade. Get a nice straight line going then start tapping the middle and hope it breaks clean. I think the angle grinder would be easier to get the cuts started right? But then it would not go as deep as the skill saw. With the 4.5" angle grinder how deep could I make the cut? Looks like harbor freight has a 9" 15 amp angle grinder. Has anybody used this one? How deep do you think I could get with that? -Nic
  7. Hello, I have a covered patio project coming up and I need to create footings. Two of the footings will be in the dirt which will be no problem, but the other four I need to cut through my existing patio. I need to cut a 12"X12" square or circle and then dig down through the dirt. It is prob 4 inches thick at least. Any ideas on how I could get a clean cut? Thanks, Nic
