yes. concrete is a fluid. Although it may appear "solid" concrete doesn't fully cure for 30 years. In nordic countries, concrete cracking is a problem due to the hot-cold/expansion-contraction cycles.

specific, you are able to placed new concrete on precise of the old. make a answer of vinegar water (if I bear in mind it quite is a a million/a million ratio like a million gal. water to a million gal vinegar), take a stiff brush and scrub the old concrete down, each and every inch. this might best the old and help the recent adhere greater ideal. besides the shown fact that, through fact you merely choose to characteristic a million a million/2 to 2 inches on precise, i'm uncertain if doing so is smart through fact the thinness of the concrete being poured makes it greater vulnerable to cracking and chipping as time is going on. I surely might take a hammer and wreck up the old concrete, then pour new. in case you go away the old in larger products (approximately 2 ft) you will be able to desire to reuse them by potential of making a walk-way with them. to try this, decrease the sod out of your walkway and lay panorama textile down (to help inhibit weed or grass strengthen if needed) placed the cement products so as that they lay flat. go away gaps between the cement products. Be ingenious. After your walkway has each and all the cement in it that it could take care of or you run out of concrete, fill the gaps left between the cement products with dirt, sand or in line with danger even ornamental stones. this might create a mosaic walkway, reuse the old concrete and ignite your creativity. If performed precise, it would desire to even provide your resale fee of the residing house a advance!!!

yes it does. that's why if you ever look at a driveway they will have a foam between the drive and your garage pad it allows a little room for expansion and contraction

both, & at different rates ( less than ) than brick, thus 18 mil poly on brick ledge ( bond breaker ).
