How do you patch or seal an exposed rebar post tension cable in foundation slab?
Rebar and Post Tension cable (PT) are two entirely different items. Rebar is the static steel bars placed in the concrete while the PT are high tensile strength cables that were placed in concrete than stressed under hydraulic jacking to a tension generally around 2500 to 3500 psi. As a result, the situations for repair are different. The exposed rebar can be cleaned and patched through approved methods. However the PT should be looked at by a professional as it is an integral part of the structure and, as mentioned before, is under tensioned stress. If the exposed rebar is in a PT slab, caution should be used and a professional consulted as well, due the rebar being integrated with the PT.
Can you cut into post tension slab?
Of course you can. But you risk cutting into a post-tension cable. That would be very bad, but there is no reason why you cannot physically do it. Just make sure you have another job lined up beforehand, and that you are prepared to live with the consequences if the cable flies out the end of the building and cuts somebody's grandma in half. Or, you can have an imaging company use X-ray or radar to locate and identify sub-surface items. Then you will know what is in the deck you are cutting. Here's one: www.srimaging.com

post tension: the forces considered as outer force since pre tension forces are internal forces.
How should you demolish part of a huge limestone slab in your basement?

How to install a 4x4 post on a concrete slab?
To install a 4x4 post on a concrete slab, you will need a hammer drill, concrete anchors, and a wrench. First, mark the location for the post on the slab. Use the hammer drill to create holes in the concrete for the anchors. Place the post in position and insert the anchors into the holes. Tighten the anchors with a wrench to secure the post to the slab.
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 I replace a porch post that is mounted on a concrete slab?
To replace a porch post mounted on a concrete slab, you will need to first remove the old post by cutting it or unscrewing it from the base. Then, you can install a new post by drilling holes into the concrete slab and securing the new post with concrete anchors or screws. Make sure the new post is level and secure before finishing the installation.
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. These types of slabs are used in constructing Floors of multi stored building. It is of two types.a) One-way Slab.b) Two Way Slab.2. Flat Slab:-Flat slab is a reinforced concrete slab secured directly by concrete columns or caps .flat slab doesn’t have beams.3. Waffle slab:- Waffle slab is a reinforced concrete roof or floor containing square grids with deep sides. This kind of slab is majorly used at entrance hotels, malls, restaurants
How can you check for post tension cables?
You can have an imaging company locate and I.D. them for you. There are several technologies to choose from. X-ray will give easily readable results but is hazardous and cannot give the depths of items in the slab. Radar is safer, more cost effective, and gives a depth, but it has a hard time imaging where there are massive amounts of tightly-spaced rebar in the slab. check out www.srimaging.com.

Can plumbing be relocated in a post tension slab?
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
