JOINTS ARE YOUR BEST DEFENSE AGAINST CRACKING

Strategic joint placement is the best defense against cracking in concrete slabs on grade. Joints are classified by function or type and are generally constructed in one of the following fashions: dowel, tied, key (tongue and groove), sawcut, tooled, insert (strips), and butt type. Joint spacing is a critical factor in design and depends primarily on slab thickness, shrinkage potential of the concrete, subgrade friction, curing environment, and absence or presence of distributed reinforcement. This article serves as a primer on joints, providing indepth discussion on various factors that affect joints.
