Types of joint Longitudinal joint

 Warping joint (Sambungan Peledingan) : tie the slabs together and can be thought of as
hinges in the slab.
 They permit small angular movements to occur between adjacent concrete slabs.
Warping stresses are very likely to occur in long narrow slabs.
 They are required in unreinforced slabs only, as in reinforced slabs the warping is kept in
check by the reinforcing bars.

 They are simply a sealed break or discontinuity in the concrete slab itself, with tie-bars
used to restrict any widening and hold the sides together.
