  Types of joint                                         Transverse joint




              Contraction joints: allow the slab to shorten as it's temperature drops
                 •      There is a crack inducer so that if cracking does occur then it is in the area of
                        reinforcement.


                                                                             Protective coating







              Expansion joints: allow the slab to expand as it's temperature increases above that at
               which it was cast.
