    What ho one and all,

    My slab is reinforced poured concrete sitting an industrial corrugated galvanized metal base with an air gap below.

    When I park the car following a wet drive, inevitably, water drips onto the concrete and there is frequently a puddle in the morning. It is probably not of concern to me, but it does cross my mind that reinforced concrete with water sitting on top can in time, cause the rebar to rust with the obvious consequences.

    Is this something I should be concerned about? Alternatively is there anything I can apply / paint on the surface to reduce the absorption of water?

    the mats at the front are to 'contain' water from the front arches, but the large damp patch is from water that I guess is dripping for the various under-body panels.

    Reinforced concrete is widely used for structures outdoors and underwater, you can even make boats out of it. The reinforcement is protected against rusting by being surrounded by very alkaline concrete. It's only a problem if the concrete is knocked off and the rebar gets exposed, and the worst that can happen is the slab cracks a bit.

    Parking a car in a garage is a waste of a good garage. Turf the car out and get a nice collection of wood offcuts, workshop tools, secondhand bikes, mismatched shelving. Much more satisfying!

    Rebar is rusty even before they pour the concrete (as a fluid with lots of water in it).

    There are lots of things intended to make a garage floor more attractive/serviceable/flat/whatever. Try searching for garage floor paint or garage floor epoxy or whatever other search terms you fancy.

    Very good!!!

    I deliberately avoided all the stuff around the car 'slot.' Work benches on either side but they are loaded with stuff and totally unusable as workbenches. Plus, some shelving piled with left-over paint from the build, 15 years ago; car related stuff, and too much other c**p.

    But I will stop worrying about rebar rust.
