Answer to Question 1

Sidewalks need shallow grooves or joints across the surface at three-foot intervals to control cracking
due to expansion.



Answer to Question 2

A construction joint is a place where one pouring of concrete stops and another begins. A control joint
is a planned break that permits concrete to expand and contract without cracking. Control joints are
placed at equally spaced intervals in the slab.
