  • How I poured a concrete slab over an existing concrete porch slab. This is video #3 of my porch to room addition series. My objective was to create a new level floor surface for my new room addition that was being created during this porch conversion project. In this case I was able to get away with pouring a concrete slab directly over the old concrete slab. I had to figure out the proper height of my new floor and build concrete forms and place them precisely.

    But, a wire mesh would be betterto hold the concrete together like a single block resting on another block of concrete , plus a sheet of plastic is recommended to reduce sweating from soil moisture into the new room,. ( Because the porch may not have had a layer of plastic under it )

    You did a nice job of forming and laying it out. I am not a concrete expert, but just from what I've done over the years, and from watching a lot of concrete poured, I think you missed a several things that would have made me say "great job!". I came here to see if anyone else was trying to do what I'm going to do. Add concrete to an existing slab, to make it level, and then install flooring over it. My customer had a guy build a room over the old pad. No kidding! It's a nightmare!!!! It's a 16' room, and it is 4+ inches low from the house to the outside wall. The original patio was stamped and stained. Ideally, grinding off the old finish and then applying a bonding agent would be the way to go. But grinding just seems out of the question for several reasons. The room is already finished, the cost to grind is going to be at least $1,000 for a 16'x24' and a good amount is going to have to come off to get to raw concrete. So, I thought we could drill holes, epoxy rebar and then attach wire mesh. Pour the concrete and level out. I would normally glue down the flooring, but because of going this route, I think a floating floor would be the far better way to install, which should eliminate any crack issues or whatever else. He doesn't have many options at this point. The idiot who poured the new part of the slab and then build a room over it should be never allow to do work for others ever again! But, that's just my opinion. Anyone have any suggestions, other than walk away from this, please reply! He's already had numerous people come by and take a look at it, and then never hears from them again. That pretty much says it all. No one is going to do this and have liability if it doesn't work. I may have to consult an attorney on this as people sue even after they sign off on liability issues.

      The process shown here in this video worked well for this particular application. The concrete pour on top of the existing porch slab project was vetted by local building regulatory officials before the concrete was even poured. The floor has performed flawlessly. Regarding your project I wish you the best of luck. If you are able please share what you end up doing. Thanks

    this is so very helpful. i watched this because i am trying to get advice on resloping concrete, without having to demo all the existing concrete. what would you recommend for not producing a weak cold joint? is a bonding agent enough to be able to pour an entire slab on top of the existing for example?

    • @MrKistel
      @MrKistel  4 ปีที่แล้ว

      Thanks for watching and commenting. Not sure I can provide the advise you are looking regarding your concrete project. For the project shown in the video a concrete bonding agent was not determined necessary. Best of luck with your project and keep me posted how it turns out.

      @MrKistel  7 หลายเดือนก่อน

      Good question! It might be a good idea to talk to an engineer. It all depends on all the variables of your project. If the new loads are substantial it may be required to put in new footers.

    • @MrKistel

      For this particular concrete pour rebar was not considered necessary. For many concrete applications rebar or wire mesh is necessary for structural reasons.

  • @patrickwardle772
    @patrickwardle772 ปีที่แล้ว

    Formwork was good, but personally I would have drilled some 50mm deep holes into the existing concrete slab and dropped 100mm Rebar lengths into them. Lay rebar mesh on seats and wire tie them as well as the upright lengths of rebar to eliminate any chance of movement. I would also include some expansion joints if the area is any bigger than this.

    I'm attempting the same thing and wondering about using a vapor barrier between the old slab and the new slab?

    • @MrKistel
      @MrKistel  3 ปีที่แล้ว

      Rebar reinforcement was determined not beneficial for this concrete floor pour application. One of the reasons was the integrity of the existing concrete floor and foundation the new slab was poured over. The new floor was not expected to receive significant flex forces which is what metal reinforcement counters. Also the paint on the existing floor was determined a good enough barrier for this application.

    Any updates on your addition? I wonder if u use block wall or wood. how much did the concrete cost you for such a small pour? Around here 1cubic yard is 550$ ,under .6cubic yard will have 300$ deliver fee on top of whatever it is. I figured buying bags for small pour cost 1/3 of the price if poured by truck. idk how some say same or cheaper. less labor sure but not sure about cheaper

    Not bad! Should have used a bonding agent and steel. It would have been more work but I would of put in temp roof supports to square off the corners then put the posts back to the finished concrete height. It looks odd having the posts sunk down on the original slab

Where your post are I have gutters coming down. Instead of making a gap around it. Can't I just cut the gutter and raise it then pour the cement all the way around the post that the gutters are attach to?

    Joe I have an existing patio just like yours. In my project, I want to make an expanded patio that runs the length of the house and also about 4 feet more on the front of the existing patio. How in the heck would you recommend that I do that? Remove the old patio, use it and poor the new concrete around it or poor over it????

    • @MrKistel
      @MrKistel  5 ปีที่แล้ว

      Thanks for the question. Not sure I have a complete understanding of the project but it might be ideal to remove the old and do the new larger "patio." If you are going to add structure you may need a proper foundation anyway. If a new foundation is not needed you might possibly be able to pour new concrete pads around the existing to accomplish your goal. Keep me posted on your project's progress. I am curious on how it all turns out.

    Nice job MrKistel. Just a few questions popped up in my mind though. I had been doing some reading before I stumbled on to your video. Didn't you need to clean the floor first of any debris and dampen the existing floor first so that the first layer doesn't suck all the water out if the new layer of concrete or did you already do that before filming? Also... Wasn't is necessary to use a concrete bonding agent first before adding the new layer of concrete or is that only optional? I read that two separate layers of concrete don't actually adhere together "chemically" and you need a mechanical bond using a concrete glue

    • @MrKistel
      @MrKistel  4 ปีที่แล้ว +1

      Thank you for your comment. I rinsed the old concrete slab with a hose prior to pouring the fresh concrete on top. This procedure cleaned the old floor a bit and added moisture to compensate for the reason you mentioned. For this application it was not necessary "attach" the new concrete layer to the old concrete floor so the new concrete slab is essentially floating. Having said that it is unlikely to move because there should not be any forces applied that would cause it to move since it is only a floor with a downward gravitational force. Also the old concrete floor had a very rough surface which the new pad will likely not slip on and the new floor is attached to the room walls. I hope this explanation helps.

    • @MrKistel

      It was filled with concrete after the old door was removed. The door was recessed below the height of the new floor, so I had to leave the temporary space in order to be able to remove the door.

  • @theashrook6129
    @theashrook6129 3 ปีที่แล้ว

    I have a dumb question. How come the new poor isn’t tied into the existing slab with rebar? Isn’t it basically one piece (albeit a heavy one) sitting loosely on another? Again I know nothing of this kind of work.

    • @MrKistel
      @MrKistel  3 ปีที่แล้ว

      It was not necessary to tie in the new concrete slab on top of the existing concrete floor for this project. Yes the new is essentially sitting on top of the old but the texture of the old floor surface provides more then enough griping area. Also framing anchors were adding prior to building the walls which were likely deep enough to reach into the old floor a good ways.

    I am wanting to do the same exact thing to my back porch. I have to admit concrete projects and especially a concrete project I need to get perfect so it is level with my homes foundation is quite intimidating. Instead of using concrete to raise my porch foundation is it possible to use wood and subfloor to raise it? That seems more beginner friendly and was wondering about your thoughts?

    • @MrKistel
      @MrKistel  3 ปีที่แล้ว

    Just a question..why did you not simply put the formwork to match the outside slab?..it could have been a drill n screw to the existing slab and angled to the front?..your thoughts because that's what I would have done..

    • @MrKistel
      @MrKistel  6 ปีที่แล้ว +5

      I think you are asking why I did not form around the perimeter of the existing slab so the new slab would match the dimensions of the old. The new slab had to terminate where the new walls would be installed and the new walls had to be placed under the beam framing of the existing roof (which is where the post are). This was to allow some overhang of the wall sheathing material over the new slab and keep water out and the sheathing off the ground at same time. This method was also required in the building permit.

      The concrete form board was placed to provide a little space. The old sliding glass door stayed in till later in the renovation project and stopped us from pouring the entire floor at one time. Once the door was removed the remaining space was patched filled with concrete to create a flush floor.

    This new concrete will adhere to the existing slab but because the shrinkage/expansion properties don't match, it will crack. Perhaps if it was designed to free float above the existing slab you could of avoided cracking.

Then make a big gutter around your patio that allows rain to goes in and to some where else. The cracks that under you're wall, just any kind that can resist the water splashes into it.

    • @MrKistel
      @MrKistel  5 ปีที่แล้ว

      Thanks Rob, the floor is still in perfect shape and I am confident will last the life of the overall structure. The concrete poured was poured over a solid and sound base (the existing concrete porch floor) which should keep the new concrete from flexing or bending at all. It is the stretching forces that typically cause concrete to fail and this is where rebar support comes in handy (the rebar limits the stretching). This new concrete floor should not be subject to any significant stretching forces thus reinforcing rebar was not deemed necessary.

      Rebars are required for structural elements that have to withstand signifiant compression and tension forces. An example would be a bridge deck and its supports or an office floor slabs and the concrete columns supporting it.

    • @dlconstruction5255

      HA AH ,They are required for all of that👍🏻and they are also required for tying into a existing structure and adding significant dead load to an existing slab you need to Tie in with rebar to the existing structure with approved epoxy at least in California it is a requirement out here. FYI ‼️To be honest I’ve been doing it for years and years and years it’s almost common sense if you think about it. If you argue that point hey sometimes you can’t teach common sense. I just got plans approved for project in California which is a patio conversion and not only is it requiring for me to tie in with rebar to the existing foundation is requiring grade beams if you’re not familiar with those those are basically continuous underpads that run underneath the existing slab.

    Nice job but you made critical mistakes.
    The new slab is not properly anchored to the old slab. You should have drilled holes into the old slab and hammered rebar into it with enough sticking up for the new slab to grab hold of.
    You should have at least run rebar around the perimeter to prevent the weight of the walls and roof from causing the lower part of the slab from wanting to spreading out from the weight. Eventually, the weight will cause the edges to start cracking and flaking off.

    • @MrKistel
      @MrKistel  5 ปีที่แล้ว +1

      This process for this particular project was determined appropriate by the local building authority. The new walls are not really load bearing and the stability of the new slab is dependent on the stability of the original structure beneath it. Rebar is most helpful when flexing forces are involved and concrete handles compression forces well.
