<b>Photo 17: Add an expansion strip </b></br> Pull off the temporary bulkhead after brooming and lay in expansion strips before continuing the next section if you're pouring two separate segments. Keep the top of the strip even with the bottom of the rounded edge of the concrete. If you're doing the sidewalk in one pour, slip the expansion strip into the wet concrete every 30 ft. and use the edger to round concrete edges.
