Permits are required for all concrete and brick paver patios, which shall be constructed as follows:
A. Concrete Slab: Shall be a minimum of four inches (4") thick poured over four inches (4") of crushed stone, gravel or grindings with six inch by six inch (6" x 6") 10/10 woven wire mesh or fiber mesh placed in the horizontal center of the poured concrete or fiber mesh. When poured against the house, rebar (#4) shall be drilled low at the base of the stone into the primary structure every three feet (3') on center. A minimum of 6-bag mix with a five inch (5") slump (8 inches for flowing concrete) shall be used. Fiber mesh may be used in lieu of woven wire mesh. All vegetation shall be removed prior to placing the gravel base.
B. An expansion joint shall be provided where patios abut previously placed concrete.
C. Install flashing behind any wood and down face of foundation where concrete is poured. The flashing shall be corrosion-resistant in accordance with 2018 IRC 703.4.
D. The concrete shall be poured not less than two inches (2") below the sill of any door within three feet (3') of the patio.
E. Guard and hand rails shall be provided where a concrete or a paver patio is elevated thirty inches (30") above grade.
F. Roof: Any patio covered with a solid roof shall have a foundation to the forty-two inch (42") frost line; any pier design shall have calculations submitted by an Illinois licensed design professional (architect or structural engineer). Where a solid roof is constructed over a patio, this will be considered an addition to the structure. The structure would then be required to comply with this code and the Bartlett Zoning Ordinance (codified at Title 10 of the Bartlett Municipal Code as amended). All plans and specifications shall be signed and sealed by an architect or structural engineer licensed by the State of Illinois.
G. Pavers: Gravel base shall be installed with sufficient voids to allow water to drain into the subgrade. A minimum of eight inches to twelve inches (8" - 12") of compacted stone shall be provided or in accordance with manufactured specifications. Add a minimum of one and one half inch (1½") of sand/screeded and level it. Pavers installed shall be compacted with joint polymetric and sand applied. Paver edge restraints shall be installed. All vegetation shall be removed and excess soil removed from the property prior to placing the gravel base for any brick pavers.
H. Inspections: A base inspection shall be performed prior to pouring or installing any concrete or brick paver patio or service walk. Final inspection required to close out the permit. (Ord. 2014-46, 6-3-2014; amd. Ord. 2020-56, 6-16-2020; Ord. 2022-07, 1-18-2022)
