The Department of Code Enforcement shall be notified when the subgrade has been finished. A minimum of three (3) hours notice shall be given prior to placing concrete. No concrete shall be placed until the subgrade has been inspected and approved by the Building Department.
Materials should not be placed on ice or frozen subgrade.
The subgrade shall be moistened just before the concrete is placed. The concrete shall be placed in successive batches for the entire width of the slab, struck off from one-half (1/2) to three-fourths (3/4) inch higher than the finished slab, tamped until all voids are removed and free mortar appears on the surface, thoroughly spaded along the edges, struck off to the true grade, and finished to a true and even surface with floats and trowels. The final troweling shall be done with a steel trowel, leaving a smooth, even surface. After the water sheen has disappeared, the surface shall be given final finish by brushing with a fine-hair broom. The broom shall be drawn across the sidewalk or driveway apron at right-angles to the edges of the slab, with adjacent strokes slightly overlapping, producing a uniform, slightly roughened surface with parallel marks.
Control Joints: Control joints shall be constructed at right angles to the center line of the sidewalk and shall extend one-fourth (1/4) the depth of the sidewalk. They shall not be less than one-eight (1/8) inch nor more than one-fourth (1/4) inch in width, and shall be edged with an edging tool having a one-fourth (1/4) inch radius. All slabs shall be five (5) feet long on any one side, unless otherwise ordered by the Village Engineer.
Control joints shall be constructed so as to divide the driveway apron into sections which are approximately square, with no side longer than fifteen (15) feet. The control joints shall be not less than one-eight (1/8) inch nor more than one-fourth (1/4) inch in width, and shall be edged with an edging tool having a one-fourth (1/4) inch radius. The minimum depth shall be one and one-fourth (1 1/4) inch.
