Concrete over concrete

[Kevin54]

As some of you know, I have been rehabbing my parents house to get it ready to sell and due to termite damage and concrete poured incorrectly against the kitchen, we have to tear out the outside patios and sidewalks out. God Bless dad, he did it all wrong but it lasted close to 35-40 years and served it's purpose.

Now, the thing is, the house was built in 1955 and I am guessing had an original patio. I remember dad pouring over a slab once, maybe one time in my life. But I never remembered ALL of this.............

There is patio pavers cemented over concrete which I remember, then there is a slab over a slab, over a slab, over what I believe is the original slab. The tang on the jackhammer on the skidloader was buried as far as it would go and NEVER hit the original slab As far as I can tell there is almost 12"+ over the original. In the last pic you can see the original slab with lines scored into it, or at least I think it is the original

Had a similar problem with the house we're renovating.Foot path over foot path over foot path!It had bridged the damp proof course in the brick wall at the front of the house by at least 10 inches.Should be below it by at least 6.
Due to the damp problem caused,a previous owner had called in a so called 'specialist' company who advised them to have the walls injected with a damp proofing liquid.Cost them a fortune but never worked.This was in the mid '80's.
It took a weekend to dig out 18 inches of **** and fix a basic problem that should have been sorted out 25 years ago!

yup, them old timers had no problem just pouring cement over everything. I built and addition on my house and discovered the sun porch floor was just shy of 4 foot thick cement. Good thing it was only 7 1/2' X 12'. What a job that was to remove...

Remember that concrete over concrete is stronger than concrete over any other kind of fill.

Yeah, I know "Holmes" thinks he has to tear everything out or gut it, but back in day you didn't just rip it all out, it was too expensive.
Our house was built in 1917 and my garage was designed for a Model T. Boy, Have I found some unique additions and repairs.

The contractor told me that he has tore out more than a few garage floors where , when he started was 8" thick and by the time he got to the back of the garage was well over 30". He said that was the way almost all of the "old timers" did it, was to just pour over a pour and not uncommon to have done it multiple times over years. Too much work to tear it out and concrete was cheap at $30/yd or less depending on the time
