Yes, it is possible. It is however, very time and dollar consuming. If it is at all possible… AVOID IT LIKE THE PLAGUE! In order to get this done it will require engineering, expensive X-Rays of the existing slab just to name a few items. There are alternatives that are much more desirable. Pumps are one that I have used extensively in the past. Hope this helps! Terry

What are the advantages and disadvantages between post tensioned slab and pre tensioned slab?
post tension: the forces considered as outer force since pre tension forces are internal forces.
Can post tension cables be placed under PVC plumbing pipes that are passing between beams in a new slab on grade without busting the piping when the cables are stressed?
Yes. Remember the cable sleeve will be encased in concrete, when stressing the cable, it will pull the ends in. The cable movement "up" will be very minimal.
Why glass slab does not produce dispersion?
surface tension
How do you fix your pool if the slab of cement at the steps into the pool is sinking and you're afraid that it will push the steps into the pool and damage the structure?
You first of all have to find out what is causing the slab to heave. If you fix the slab then within a two year period you will be redoing the slab again. You may have a leak in the plumbing of the pool or a leak in the house plumbing or to the garden hose. Fix all the leaks and then replace the slab.
What is plumbing slab rough in?
That is the underground drainage plumbing under a concrete floored dwelling, which has to pass inspection before the concrete is poured.
What is a minimum thickness for a residential slab?
For a conventional slab, 3 1/2". If you go 3 1/2" on a post tension slab (and some builders do...) the tops of the cables will be just below the top of the surface and surface cracks will form above the cables. I have even seen where the power screed will cut into the black cable cover.
How can you tell if the plumbing is broken below a concrete slab?
if the concrete is cracked or there is leaking .... if not call a professional.
Does homeowners insurance cover plumbing breaks under the slab?
Contact your agent and ask them if you are covered.
Is it safe to cut the post tension concrete slab foundation to fine sewer line for bathroom addition?
No, You must first locate the P.T cables, and because you said it is to find a sewer line im guessing this is slab-on-grade and not a deck. The only method for locating post tension cables on slab-on-grade is with Ground Penetrating Radar. If its on a deck you can use Ground Penetrating Radar or Xray. If you cut a P.T. cable you can weaken the structure and cause damage. P.T cables are known to shoot out of the side of a building when cut. And repairing the broken cable is extremely costly. You can learn a little more about GPR at www.subsurfacepros.com
What are the different types of concrete slabs?
Different types of Slabs :1. Conventional solid slab:-- the slab which is braced with beams and columns is called conventional slab this kind of slab is small whereas the depth of the beam is large and load is transferred to beams and from beams to columns.

Can we Put a 6 feet hole in a reinforced concrete slab of 8 inches?
That would depend on where the slab was and what it was doing. How close to a wall is it? What's under the slab? Rock, plumbing? Can you do it? Yes. Should you? Good question. What may happen varies with each slab and circumstance. You may bust it out and find a large rock under it and have to replace it.
