The last common layout is what is known as an integral sidewalk setup. In this layout, the sidewalk and the curb and gutter are poured simultaneously with no joint in between them (as shown in Figure 3.2c). We refer to this type as “True” integral sidewalks (whereas the previous example in Fig. 3.2b will be referred to simply as Integral sidewalks).

Another thing to note is a special case involving “True” integral sidewalks.

Sometimes the curb portion of the integral sidewalk may chip, crack, or spall.

Even though this affects the curb portion and not the sidewalk portion, the deficiency may propagate towards the sidewalk over time since there is no joint present between the curb and sidewalk. Therefore these deficiencies need to be noted during the inspection. Please refer to Figure 3.2d below.
