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.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310234#Comment_310234 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310234#Comment_310234 Tue, 17 Feb 2026 18:05:18 +0000 WillInAberdeen
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!]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310235#Comment_310235 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310235#Comment_310235 Tue, 17 Feb 2026 19:44:41 +0000 fostertom https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310236#Comment_310236 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310236#Comment_310236 Tue, 17 Feb 2026 20:42:17 +0000 djh
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.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310237#Comment_310237 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310237#Comment_310237 Wed, 18 Feb 2026 06:39:18 +0000 Peter_in_Hungary Posted By: WillInAberdeenParking a car in a garage is a waste of a good garage.

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.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310257#Comment_310257 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=18406&Focus=310257#Comment_310257 Fri, 20 Feb 2026 19:43:37 +0000 revor Posted By: WillInAberdeenParking a car in a garage is a waste of a good garage.

You should never put a wet car in a garage until it is dry. You should be more worried about the car rusting than the concrete deteriorating. There are a lot of concrete paints to choose from. There are also wide rolls of tough vinyl floor covering or tiles available.
