My back door stoop has 2 big cracks in it. I can tell from knocking on the cement that it is hollow inside. I'm thinking of putting deck over the concrete as shown in the video "How to Deck Over a Concrete Stoop" on this site.
How do I address the crack to prevent water seeping thru ?
Would it be worth breaking thru the crack and filling the void with cement ?
Thanks for your time.
