Do you need to reinforce the floor of a raft foundation?

If the raft foundation is subject to a uniform load (Water & oil Tanks ..etc) u may not be required to reinforce the floor, only a plain concrete or even well compacted earth is sufficient provided it 'll transfere the load safely i.e giving a pressure less than the allowable bearing capacity of the underlying soil. Only peripheral or ring beams of reinforced concrete is required under the tank walls. If the raft is supporting colmns/walls, then it's subject to knife loads & got to be reinforced.


Can concrete set under water?

Yes. Water is actually needed for concrete to set and is vital to the curing process. Concrete will set just fine under water. Depending on your specific application (will all of the pour be under water or will it start under water and finish above the water line) you may need to adjust the initial dryness of the mix as well as take more care in the pour. All of the volume of the concrete that is under water shoudl be poured in continuous fashtion. If you must pour in steps, the start of the next pour must be "in" the old pour so as to not leave a water survice between the pours. This "seam" will tend to stay and produce a weaker stucture.

Is there a repair method for slab water leaks that doesn't require floor removal?

The usual way to fix it is to run new pipes up in the attic and back down. There is no way to fix the pipe under the floor. This is for supply lines only, drains require busting out the floor. Epoxy coating can be done if breaking the floor is absolutely not an option. It is often more costly than a spot repair, and is rarely if ever covered by insurance, but does not require the breaking of the concrete. It is also a good option if the pipes are deteriorating and are likely to continue developing leaks. Rerouting is a good option if you are in a climate that is not likely to freeze.


Can you paint the concrete floor as soon as muriatic acid etching dries?

To test a concrete floor for sufficient dryness before painting you should tape a two foot by two foot square of (clear) plastic film to the floor, wait 48 hours and see if the concrete is darker under the plastic or if any condensation has occurred on the underside of the plastic. If so then the floor is not dry enough. If no condensation or darkness, paint.
