My garage area, which is currently just a concrete slab for parking cars on, has a natural spring that pops up just at ground level. The water never stops, and the concrete there is permanently wet all over. Im hoping to create a channel so that the water is funnelled around the sides of the concrete base, and later into a pond area set below the concrete. My problem is how to fix some kind of guiding masonry such as a row of bricks, onto the floor in a way that will be totally waterproof – but which will also fix to the floor, which will be wet during the process. Is there a concrete or similar material which will glue itself onto a very wet concrete base? Failing that, any other ideas for how to create a channel that will send this water around the sides of my concrete base, and not leave it covered all over? Any help appreciated.

You want hydraulic concrete.
Hydraulic concrete is a concrete that will bond to other surfaces when wet, and cure when wet. It can even be used underwater.
This page will give some guidance on how to apply.
Given the nature of hydraulic cement I'm thinking that your best bet is - in a dry place, build something that you can put in place to divert the water. Test it by "dry" (haha) fitting it against the spring (if thats the word), and once you're satisfied that it will divert the water properly once sealed, clean the wet space (Pressure washer, lose the moss and stuff) then seal in your diverter system with the hydraulic cement.
