hello everyone , im currently involved in building a concrete skatepark, and im wondering for the final skin , what mix ratio to use to make the concrete as chip-proof as is possible and still not be brittle at the point where the transitions meet the floor ? every time we lay something it lasts a few days then starts to crack and chunks fall away ! please help !
