TERMITE PROTECTION
<br />R 318.1 Termite Protection.
<br />Termite protection shall be provided by registered termiticides, including soil applied
<br />pesticides. baiting systems, and pesticides applied to wood, or other approved
<br />methods of termite protection labeled for use as a preventative treatment to new
<br />construction. See Section 202. 'Registered termiticide.' Upon completion of the
<br />application of the termite protective treatment, a Certificate of Compliance shell be
<br />issued to the building department by the licensed pest control company that contains
<br />the following statement: "The budding has received a complete treatment for the
<br />prevention of subterranean termites. Treatment is in accordance with rules and laws
<br />established by the Florida Department of Agriculture and Consumer Services."
<br />R 319.1.1 If soil treatment is used for subterranean termite prevention, the initial
<br />chemical soil treatment inside the foundation perimeter shall be done after all
<br />excavation, backfilting and compaction is complete.
<br />R 318.1.2 If soil treatment is used for subterranean termite prevention, soil area
<br />disturbed after initial chemical soil treatment shall be retreated with a chemical soil
<br />treatment, including spaces boxed or formed.
<br />R 318.1.3 If soil treatment is used for subterranean termite prevention. space in
<br />concrete floors boxed out or formed for the subsequent installation of plumbing traps,
<br />drains or any other purpose shall be created by using plastic or metal permanently
<br />placed forms of sufficient depth to eliminate any planned soil disturbance after initial
<br />chemical soil treatment.
<br />R 318.1.4 If soil treatment is used for subterranean termite prevention, chemically
<br />treated soil shall be protected with a minimum 6 mil vapor retarder to protect against
<br />rainfall dilution. If rainfall occurs before vapor retarder placement, re -treatment is
<br />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
<br />penetrating or disturbing treated soil.
<br />R 318.1.5 If soil treatment is used for subterranean termite prevention, concrete over
<br />pour or mortar accumulated along the exterior foundation perimeter shall be removed
<br />prior to exterior chemical soil treatment, to entrance vertical penetration of the
<br />chemicals,
<br />R 318.1.6 If soil treatment is used for subterranean termite prevention, chemical soil
<br />treatments shall also be applied under all exterior concrete or grade within 1 foot (305
<br />mm) of the primary structure sidewalls. Also, a vertical chemical barrier shall be applied
<br />promptly after construction is completed. including initial landscaping and imigationl
<br />sprinkler installation. Any soil disturbed after the chemical vertical barrier Is applied
<br />stall be promptly retreated.
<br />R 318.1.7 If a registered termiticide formulated and registered as a bait system is used
<br />for subterranean termite prevention, Sections 1816.1.1through 1816.1.6 do not apply;
<br />however, a signed contract assuring the Installatlon, maintenance and monitoring of
<br />the batting 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
<br />the system must be installed prior to final bt.ilding approval.
<br />11 the batting system directions for use require a monitoring phase prior to installation of
<br />the pesticide active ingredient, the installation of the monitoring phase components
<br />shall be deemed to constitute installation of the system.
<br />R 318.1.8 If a registered termiticide formulated and registered as a wood treatment is
<br />used for subterranean termite prevention, Sections 1816.1.1 through 1816.1.6 do not
<br />apply. Application of the wood treatment termiticide shall be as required by label
<br />directions for use. and must be completed prior to final building approval.
<br />R 318.2 Psrnotration.
<br />Protective sleeves around piping penetrating concrete slab on grade floors shall not be
<br />of cellulose containing materials. If soil treatment is used for subterranean termite
<br />protection, the sleeve shall have a maximum wall thickness of 0.010 inch (0.254 mm),
<br />and be sealed within the slab using a non -corrosive clamping device to eliminate the
<br />annular space between the pipe and the sleeve. No termiticides shall be applied inside
<br />the sleeve.
<br />R 318.3 Cleaning.
<br />Cells and cavities in masonry units and air gaps between brick, stone or masonry
<br />veneers and the structure shall be cleaned of all non preservative - treatment or non
<br />naturally durable wood. or other cellulose - containing material prior to concrete
<br />placement.
<br />Exceptions: Inorganic material manufactured for nosing cells In foundation concrete
<br />masonry unit construction or clean earth placed in concrete masonry unit voids below
<br />slab level termite treatment is performed.
<br />R 318,4 Concrete bearing ledge.
<br />Brick, stone or other veneer shall be supported by a concrete bearing ledge at least
<br />equal to the total thickness of the brick, stone pr other veneer which is poured
<br />integrally with the concrete foundation. No supplemental concrete foundation pours
<br />which create a hidden cold joint shall be used without supplemental treatment in the
<br />foundation unless there is an approved physical barrier. An approval physical barrier
<br />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
<br />treatment must be applied to the cavity created between the veneer and the
<br />foundation, in lieu of a physical barrier.
<br />Exception: Veneer supported by a structural member secured to the foundation
<br />sidewall in accordance with ACI 530/ASCE 51TMS 402, provided at least 6 inch (152
<br />mm) clear inspection space of the foundation sidewall exterior exists between the
<br />veneer and the top of any soil, sod, mulch or other landscaping component, deck,
<br />apron, porch, walk or any other work immediately adjacent to or adding the structure.
<br />R 318.5 Protection against decay and termites.
<br />Condensate lines, irrigation / sprinkler system risers for spray heads, and roof
<br />downspouts shall discharge at least 1 foot (305 mm) away from the structural sidewall,
<br />weather by underground piping, tail extensions or splash blocks. Gutters with
<br />downspouts are required on all buildings with eves of less than 6 inches (152 mm)

<br />removed from under the building and within 1 foot (305 mm) thereof. All wood forms
<br />and supports shall be completely removed. This includes, but is not limited to: wooden
<br />grade stakes, forms, contraction spacers, tub trap boxes, plumbing supports, bracing,
<br />shoring, forms or other cellulose - containing material placed in any location where
