concrete surface flaking
Posted by Lee from Maysville, KY, US on June 22, 2007
I have a problem with surface of my concrete driveway flaking off.
Eight months after concrete was poured, the top eighth inch is flaking off, in a lot of different places. There are a lot of spots you can see that are loose and will flak off.
Can you tell me what could have caused this problem, Also I would like to know if a topping of some kind can be used, If so what kind of
topping would be best, And how to prepare surface before appling a topping. My contractor tells me he is going to fix it, But he dose not seem to know just what to do.
THANKS FOR ANY ADVICE YOU CAN GIVE
Dear Lee,
Some one had asked a very similar question few months back. Please scroll back 2 pages on the link were questions are answered on this website and you can read the reply to that question. (http://expert.concreteproducts.com/admixtures/page/3/)
Apart from that answer such problems also occur sometimes due to alkali- aggregate reactions, if the aggregate used is reactive or if the pavement is damaged due to freeze thaw.
thanks
