(a) Driveways for New Dwellings. All driveways for new dwellings constructed in the City after the effective date of this section shall be Portland cement concrete or brick pavers of equal or greater strength than Portlamd cement concrete in thicknesses required by the Codified Ordinances of the City of Seven Hills.
(Ord. 105-1992. Passed 1-11-93.)
(b) Replacement of Existing Driveways. Replacement of existing gravel, aggregate, brick or concrete driveways replaced in the City of Seven Hills after the effective date of this section, shall be Portland cement concrete, asphaltic concrete or brick pavers of equal or greater strength than Portland cement concrete in thickness equal to Portland cement concrete required by the Codified Ordinances of the City of Seven Hills. Where brick pavers are used, a proper base and base material must be used to establish a stable foundation.
(1) Excavation and Base. For light traffic areas excavate 5" to 6" where the pavers are to be laid. Three to 4" will be the #9d crushed limestone material and 2-3/8" for the pavers laid on top. The base and pavers combined will equal 5" to 6".
For drives or heavy traffic areas. Excavate 10" where pavers are to be laid. Place 5" of #57 limestone (3/4") in the excavated area. Place 3" of the #9d crushed limestone on top of the #57. This combination will ensure proper drainage. The base and pavers combined equal 10". Proper compaction of subgrade and base are important to successful installation.
(2) Edging. An edge should be used to hold the entire patio or driveway together. Some typical edges include landscape timbers and various curbing edges such as plastic, steel, or aluminum which must be approved by the Building Board.
(3) Sanding. Sweep fine silica sand or mason sand into the joints of the pavers. This “sanding” locks the paver in and tightens the entire patio. Sweep off the excess sand and hose patio off with water. Let dry and repeat this sanding process.
(Ord. 22-1995. Passed 7-10-95.)
(c) Concrete Usage; Quality. Any and all concrete used for the purposes set forth in this section shall:
(1) Contain a cement content of six and one-half bag mix at ninety-four pounds per bag, of Portland cement;
(2) Have an air entrainment of six percent (6%) to eight percent (8%) at the time of pour;
(3) Consist of sound, coarse aggregate (one inch or smaller required);
(4) Contain no more water than will permit a slump between a minimum of four inches and a maximum of six inches;
(5) Have a uniform thickness of five inches in the driveway and six inches in the apron from the property line to the curb or street line; and
(6) Be reinforced with wire reinforcing mesh having a maximum spacing of six inches in either parallel direction between wires and a minimum wire size of Number 10 U.S. Gauge.
(d) Curing; Mixing; Finishing.
(1) Curing compound shall be applied immediately after broom finishing, without damaging the surface, according to the manufacturer's recommendation.
(2) Calcium or other admixtures shall not be added at the job site.
(3) Minimum floating and finishing shall be required. A broom or trowel finish shall be required. Finishing must be delayed until water sheen (bleed water) has disappeared from the surface.
(Am. Ord. 120-1985. Passed 3-24-86.)
(e) Base.
(1) The base must be smooth and consist of undisturbed or compacted earth. Stone, gravel, limestone screenings, ornonsettlingmaterial, approved by the Building Department, may be used as a leveling course. Excavations or trenches under a drive must be compacted or filled with a nonsettling material.
(2) The subgrade or base shall be dampened, if dry, before pouring.
(f) Joints.
(1) Control joints, whether hand-tooled or sawn, shall be to a depth of one-quarter the thickness of the slab. The dimension of any control joint panel shall not exceed ten feet.
(2) Isolation joints shall be required where concrete abuts any structure, including, but not limited to, foundations, garage floors, stoops and paved streets.
(g) Time of Pour.
(1) Where the temperature in the surrounding area is below seventy degrees Fahrenheit, the maximum allowable time from loading to pour shall be one and one-half hours.
(2) Where the temperature in the surrounding area is above seventy degrees Fahrenheit, the maximum allowable time from loading to pour shall be one hour.
(3) When concrete is placed at or belong an atmospheric temperature of forty degrees Fahrenheit, or whenever the predicted temperature will fall below forty degrees Fahrenheit within the curing period, the water, aggregates, or both, shall be heated and suitable enclosures and heating devices shall be provided. The concrete shall be placed at a temperature of not less than fifty degrees Fahrenheit and not more than seventy degrees Fahrenheit.
