Termite Protection
<br />R 318.1 Termite Protection.
<br />Termite protection shall be provided by registered termiticides, including soil applied pesticides,
<br />baiting systems and pesticides applied to wood, or other approved methods of termite protection
<br />labeled for use as a preventative treatment to new construction. See Section 202, Registered
<br />termiticide. Upon completion of the application of the termite protective treatment, a Certificate of
<br />Compliance shall be issued to the building department by the licensed pest control company that
<br />contains the following statement: "The building has received a complete treatment for the prevention
<br />of subterranean termites. Treatment is in accordance with rules and laws established by the Florida
<br />Department of Agriculture and Consumer Services."
<br />R 318.1.1 If soil treatment is used for subterranean termite prevention, the initial chemical soil
<br />treatment inside the foundation perimeter shall be done after all excavation, backfilling and
<br />compaction is complete.
<br />R 318.1.2 If soil treatment is used for subterranean termite prevention, soil area disturbed after initial
<br />chemical soil treatment shall be retreated with a chemical soil treatment, including spaces boxed or
<br />formed.
<br />R 318.1.3 If soil treatment is used for subterranean termite prevention, space in concrete floors boxed
<br />out or formed for the subsequent installation of plumbing traps, drains or any other purpose shall be
<br />created by using plastic or metal permanently placed forms of sufficient depth to eliminate any
<br />planned soil disturbance after initial chemical soil treatment.
<br />R 318.1.4 If soil treatment is used for subterranean termite prevention, chemically treated soil shall be
<br />protected with a minimum 6 mil vapor retarder to protect against rainfall dilution. If rainfall occurs
<br />before vapor retarder placement, re -treatment is required. Any work, including placement of
<br />reinforcing steel, done after chemical treatment until the concrete floor is poured, shall be done in
<br />such manner as to avoid penetrating or disturbing treated soil.
<br />R 318.1.5 If soil treatment is used for subterranean termite prevention, concrete over pour or mortar
<br />accumulated along the exterior foundation perimeter shall be removed prior to exterior chemical soil
<br />treatment, to enhance vertical penetration of the chemicals.
<br />R 318.1.6 If soil treatment is used for subterranean termite prevention, chemical soil treatments shall
<br />also be applied under all exterior concrete or grade within 1 foot (305 mm) of the primary structure
<br />sidewalls. Also, a vertical chemical barrier shall be applied promptly after construction is completed,
<br />including initial landscaping and irrigation/sprinkler installation. Any soil disturbed after the chemical
<br />vertical barrier is applied shall be promptly retreated.
<br />R 318.1.7 If a registered termiticide formulated and registered as a bait system is used for
<br />subterranean termite prevention, Sections 1816.1.1through 1816.1.6 do not apply; however, a signed
<br />contract assuring the installation, maintenance and monitoring of the baiting system for a minimum of
<br />5 years from the issue of the Certificate of Occupancy shall be provided to the building official prior to
<br />the pouring of the slab, and the system must be installed prior to final building approval.
<br />if the baiting system directions for use require a monitoring phase prior to installation of the
<br />pesticide active ingredient, the installation of the monitoring phase components shall be
<br />deemed to constitute installation of the system.
<br />R 318.1.8 If a registered termiticide formulated and registered as a wood treatment is used
<br />for subterranean termite prevention, Sections 1816.1.1 through 1816.1.6 do not apply.
<br />Application of the wood treatment termiticide shall be as required by label directions for use,
<br />and must be completed prior to final building approval.
<br />R 318.2 Penetration.
<br />Protective sleeves around piping penetrating concrete slab on grade floors shall not be of cellulose
<br />containing materials. If soil treatment is used for subterranean termite protection, the sleeve shall
<br />have a maximum wall thickness of 0.010 inch (0.254 mm), and be sealed within the slab using a non-
<br />corrosive clamping device to eliminate the annular space between the pipe and the sleeve. No
<br />termiticides shall be applied inside the sleeve.
<br />R 318.3 Cleaning.
<br />Cells and cavities in masonry units and air gaps between brick, stone or masonry veneers and the
<br />structure shall be cleaned of all non preservative - treatment or non naturally durable wood. or other
<br />cellulose - containing material prior to concrete placement.
<br />Exceptions: inorganic material manufactured for closing cells in foundation concrete masonry unit
<br />construction or clean earth placed in concrete masonry unit voids below slab level termite treatment is
<br />performed.
<br />R 318.4 Concrete bearing ledge.
<br />Brick, stone or other veneer shall be supported by a concrete bearing ledge at least equal to the total
<br />thickness of the brick, stone pr other veneer which is poured integrally with the concrete foundation.
<br />No supplemental concrete foundation pours which create a hidden cold joint shall be used without
<br />supplemental treatment in the foundation unless there is an approved physical barrier. An approval
<br />physical barrier shall also be installed from below the wall sill plate or first block course horizontally to
<br />embed in a mortar joint. If masonry veneer extends below grade, a termite protective treatment must
<br />be applied to the cavity created between the veneer and the foundation, in lieu of a physical barrier.
<br />Exception: Veneer supported by a structural member secured to the foundation sidewall in
<br />accordance with ACI 530/ASCE 5/TMS 402, provided at least 6 inch (152 ni clear inspection space
<br />of the foundation sidewall exterior exists between the veneer and the top of any soil, sod, mulch or
<br />other landscaping component, deck, apron, porch, walk or any other work immediately adjacent to or
<br />adding the structure.
<br />R 318.5 Protection against decay and termites.
<br />Condensate lines, irrigation / sprinkler system risers for spray heads, and roof downspouts shall
<br />discharge at least 1 foot (305 mm) away from the structural sidewall, weather by underground piping,
<br />tail extensions or splash blocks. Gutters with downspouts are required on all buildings with eves of
<br />less than 6 inches (152 mm) horizontal projection except for gable end rakes or on a roof above
<br />another roof.
<br />R 318.6 Preparation of building site and removal of debris.
<br />R 318.6.1 All building sites shall be graded to provide drainage under all portions of the building not
<br />occupied by basements.
<br />R 318.6.2 The foundation and the area encompassed within 1 foot (305 mm) therein shall have all
<br />vegetation, stumps, dead roots cardboard, trash and foreign material removed and the fill material
<br />shall be free of vegetation and foreign material. The fill shall be compacted to assure adequate
<br />support of the foundation.
<br />R 318.6.3 After all work is completed, loose wood and debris shall be completely removed from _
<br />under the building and within 1 foot (305 mm) thereof. All wood forms and supports shall be
<br />completely removed. This includes, but is not limited to: wooden grade stakes, forms, contraction
<br />spacers, tub trap boxes, plumbing supports, bracing, shoring, forms or other cellulose - containing
<br />material placed in any location where such materials are not clearly visible and readily removable
<br />prior to completion of the work. Wood shall not be stored in contact with the ground under the
<br />building.
<br />R 318.7 Inspection for termites.
<br />In order to provide for inspection for termite infestation, clearance between exterior wall coverings
<br />and final earth grade on the exterior of a building shall not be less than 6 inches (152 mm).
