<br />PROTECTION AGAINST TERMITES
<br />R320.1 Termite Protection. Termite protection shall be provided by registered termiticides, including soil applied
<br />pesticides, baiting systems and pesticides applied to wood, or other approved methods of termite protection labeled for
<br />use as a preventative treatment to new construction. See Section 202, Registered terrmiticide. Upon completion of the
<br />application of the termite protective treatment, a Certificate of Compliance shall be issued to the building department
<br />by the licensed pest control company that contains the following statement: 'The building has received a complete
<br />treatment for the prevention of subterranean termites. Treatment is in accordance with rules and laws established by
<br />the Florido Department of Agriculture and Consumer Services."
<br />R320.1.1 If soil treatment is used for subterranean termite prevention, the initial chemical soil treatment inside
<br />the foundation perimeter shall be done after all excavation, bockfilling and compaction is complete.
<br />R320.1.2 If soil treatment is used for subterranean termite prevention, soil area disturbed after initial chemical soil
<br />treatment shall be retreated with a chemical soil treatment, including spaces boxed or formed.
<br />R320.1.3 If soil treatment is used for subterranean termite prevention, space in concrete floors boxed out or
<br />formed for the subsequent installation of plumbing traps, drains or any other purpose shall be created by using
<br />plastic or metal permanently placed forms of sufficient depth to eliminate any planned soil disturbance after initial
<br />chemical soil treatment.
<br />R320.1.4 If soil treatment is used for subterranean termite prevention, chemically treated soil shall be protected
<br />with a minimum 6 mil vapor retarder to protect against rainfall dilution. If rainfall occurs before vapor retarder
<br />placement, retreotment is required. Any work, including placement of reinforcing steel. done after chemical
<br />treatment until the concrete floor is poured, shall be done in such manner as to avoid penetrating or disturbing
<br />treated soil.
<br />R320.1.5 If soil treatment is used for subterranean termite prevention, concrete overpour or mortar accumulated
<br />along the exterior foundation perimeter shall be removed prior to exterior chemical soil treatment, to enhance
<br />vertical penetration of the chemicals.
<br />R320.1.6 If soil treatment is used for subterranean termite prevention, chemical soil treatments shall also be
<br />applied under all exterior concrete or grade within 1 foot (305 mm) of the primary structure sidewalls. Also, a
<br />vertical chemical barrier shall be applied promptly after construction is completed, including initial landscaping and
<br />irrigation/sprinkler installation. Any soil disturbed after the chemical vertical barrier is applied shall be promptly
<br />retreated.
<br />R320.1.7 If a registered termiticide formulated and registered as a bait system is used for subterranean termite
<br />prevention, Sections R320.1.1through R310.1.6 do not apply; however, a signed contract assuring the installation.
<br />maintenance and monitoring of the baiting system for a minimum of 5 years from the issue of the Certificate of
<br />Occupancy shall be provided to the building official prior to the pouring of the slab, and the system must be
<br />installed prior to final building approval. If the baiting system directions for use require a monitoring phase prior
<br />to installation of the pesticide active ingredient, the installation of the monitoring phase components shall be
<br />deemed to constitute installation of the system.
<br />R320.1.8 If a registered termiticide formulated and registered as a wood treatment is used for subterranean
<br />termite prevention, Sections R320.1.1 through R320.1.6 do not apply. Application of the wood treatment termiticide
<br />shall be as required by label directions for use, and must be completed prior to final building approval.
<br />R320.2 Penetration. Protective sleeves around metallic piping penetrating concrete slab -on -grade floors shall not be of
<br />cellulose -containing materials and, if soil treatment is used for subterranean termite protection, shall receive
<br />application of a termiticide in annular space between sleeve and pipe.
<br />R320.3 Cleaning. Cells and cavities in masonry units and air gaps between brick, stone or masonry veneers and the
<br />structure shall be cleaned of all nonpreservative treated or nonnaturally durable wood, or other cellulose -containing
<br />material prior to concrete placement.
<br />Exception: Inorganic material manufactured for closing cells in foundation concrete masonry unit construction or
<br />dean earth fill placed in concrete masonry unit voids below slab level before termite treatment is performed.
<br />R320.4 Concrete bearing ledge. Brick, stone or other veneer shall be supported by a concrete bearing ledge of such
<br />thickness as required in Chapter 14, which is poured integrally with the concrete foundation. No supplemental concrete
<br />foundation pours which will create a hidden cold 'pint shall be used without supplemental treatment in the foundation
<br />unless there is an approved physical barrier. An approved physical barrier shall also be installed from below the wall sill
<br />plate or first block course horizontally to embed in a mortar pint. If masonry veneer extends below grade, a termite
<br />protective treatment must be applied to the cavity created between the veneer and the foundation, in lieu of a
<br />physical barrier.
<br />Exception: Veneer supported by a structural member secured to the foundation sidewall as provided In Section
<br />1403, provided at least a 6 inch (152 mm) clear inspection spats of the foundation sidewall exterior exist
<br />between the veneer and the top of any soil, sod, mulch or other organic landscaping component, deck, apron,
<br />porch, walk or any other work immediately adjacent to or adjoining the structure.
<br />R320.5 Pressure preservatively treated and naturally resistant wood. Heartwood of redwood, eastern red cedar, and
<br />pressure- preservative -treated wood in accordance with the AWQA standards fisted in Section R319.1 shall be
<br />considered termite resistant. Pressure preservatively treated wood and naturally termite- resistant wood shall not be
<br />used as a physical barrier unless a barrier can be inspected for any termite shelter tubes around the inside and
<br />outside edges and joints of a barrier.
<br />R320.5.1 Quality mark. Lumber and plywood required to be pressure -preservative treated in accordance with
<br />Section R320.1 shall bear the quality mark of an approved inspection agency which maintains continuing
<br />supervision, testing and inspection over the quality of the product and which has been approved by an
<br />accreditation body which complies with the requirements of the American Lumber Standard Committee's treated
<br />wood program.
<br />R320.5.2 Field treatment. Field cut ends, notches and drilled holes of pressure-preservatively treated wood shall
<br />be retreated in the field in accordance with AWPA M4.
<br />R320.6 Foam plastic protection. Extruded and expanded polystyrene, polyisocyonurate and other foam plastics shall not
<br />be installed on the exterior face or under interior or exterior foundation walls or slab foundations located below grade.
<br />The clearance between foam plastics Installed above grade and exposed earth shall be at least 6 inches (152 mm).
<br />Exceptions: 1. Buildings where the structural members of walls, floors, ceil ings and roofs are entirely of
<br />noncombustible materials or pressure -preservative- treated wood. 2. when in addition to the requirements of
<br />Section R320.1, an approved method of protecting the foam plastic and structure from subterranean termite
<br />damage is used 3. On the interior side of basement walls.
<br />R320.7 Protection against decay and termites. Condensate lines and roof downspouts shall discharge at least 1 foot
<br />(305 mm) away from the structure sidewall, whether by underground piping. tail extensions or splash blocks. Gutters
<br />with downspouts are required on all buildings with eaves of less than 6 inches (152 mm) horizontal projection except
<br />for gable end rakes or on a roof above another roof.
