Seven to 28 days According to Concrete Network, concrete should be allowed to cure for at least seven days before it's built on. However, waiting longer will greatly reduce the risk of the concrete cracking. Concrete continues to cure up to 28 days after it is poured, at which point it reaches maximum strength. Bottom Line When a contractor or engineer is in charge of a project, follow the professional's advice, since the result of curing is his responsibility, according to Builder Bill. 4.How long does it take for concrete to dry enough to walk on? Wind, humidity, and sunlight are all factors in how long it takes for concrete to cure, walking, normally about 1 to 2 days. 5. How long does it take for concrete to cure enough to drive on?

Final cure date is 28 days from placement date, which is considered the adequate duration of curing by the American Concrete Institute. Been here over 20 years and still no problems. It will likely take four weeks for the concrete to reach it's full compressive strength. (Nominally, this is about 4000 psi on average) Some might tell you it's ok to begin framing immediately, but it is best to wait. with out all the b.s.

Letters From Our Customers. 1 Thank you Rebecca & Ryan for the exceptional job you do managing the office and meeting customer needs. 2 The new chain link fence is wonderful! 3 Wanted to let you know what a great job your crew did on our new black chainlink fence. 4 Thank you for a wonderful job on our fence. Best Answer: the footer should be poured with 4000 psi concrete with fiber reinforcment and 3 runs of rebar and your walls should always be poured 4000 psi with fiber and a 2 feet on center rebar mat and for a smoother wall when the forms are pulled try a smaller rock like 3/8 to 1/2 inch aggregate but to answer your question a good crew can be done in a week, our crew on average forms and pours one and gets another ready to be poured after the weekend, but i've seen some crews ...
