garage floor sealing

hi lads,

done some researching but thought I would ask here since you guys love the wet weather

I recently moved house and my garage gets oxidation spots, unfortunately my new house is on a significant slope, so alot of water comes down from the neighbour above.

In terms of the garage floor, any have recommendations to seal it and prevent this from happening?

I have a few smaller pieces of that stuff but i was just wondering if there was something I can do to help prevent the underlying problem of it coming through the concrete or it doesnt really matter.

Concrete is porous , water can either enter from the top or below , it will dry out depending on how much sun it gets , sealing the top layer will stop water passing but it’s expensive and if water is coming from below will stop drying out and can cause cracking if the water freezes in winter .
Some drain may be necessary to prevent water ingress in the first place , but this may or may not be practical depending on the location of the water and area size or length .
It is really a cosmetic thing as the salts rise through the concrete rather than a structural thing , using mats would be the cheapest option I think and much less effort than laying a damp course and maybe concrete tiles
Over the top .
The problem probably stems from the original floor instal , with not enough drainage or over clay type soil , unfortunately we lost the ability to build at high standards , that’s why 200 year old houses will be up in another 200 years and new build lucky to last 50 !!
Victorian builders paid thruppence a year , modern builders /developers drive Porsche’s
Go figure ..

Thanks for the advice mate, I’ve actually brought enough of that flooring to cover 3/4’s of my garage. I’ll cover it up and forget about it, I’m sure it will be fine for the length of time I own the house. I was concerned it might do damage long term. Ideally I think there is some drainage issues that need to be addressed from the property above me but that’s a whole another issue I’ll need to deal with.
