POUR THE CONCRETE OVER THE BRICK
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.

In larger concrete projects with a good quality control program, a pour card is a document that describes the location of the concrete being poured, type/specification of concrete being supplied, a signature block by the inspector and/or engineer indicating that the rebar has been inspected in-place and approved, date of pour, serial number of the concrete truck(s) supplying the concrete, sign-off by the inspector indicating on-site tests for slump and air entrainment (if required) have been completed. Temperature, weather and ticket info from the concrete batch plant/delivery truck are also recorded. The contractor's quality assurance manager will typically keep all the pour cards for a project on file, especially in the even that subsequent testing indicates substandard concrete was installed.

not normally. it depends on what you are trying to accomplish. if you need a thin layer than you can pour a thin set layer which hardens and adheres better than concrete. if the added part is thicker you can drill holes in the old and put re bar in then pour on top to help tie the two together.
