<br />N01 DATE DESCRIPTION
<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 shall be
<br />issued to the building department by the licensed pest control company that contains
<br />the following statement: "The building 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 318.1.1 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, backfilling 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, retreatment 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
<br />overpour or mortar accumulated along the exterior foundation perimeter shall be
<br />removed prior to exterior chemical soil treatment, to enhance 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 sidewalis. Also, a vertical chemical barrier shall be applied
<br />promptly after construction is completed, including initial landscaping and irrigation/
<br />sprinkler installation. Any soil disturbed after the chemical vertical barrier is applied
<br />shall 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 R318.1.1 through R318.1.6 do not apply;
<br />however, a signed contract assuring the installation, maintenance and monitoring of
<br />the baiting system that is in compliance with the requirements of Chapter 482, Florida
<br />Statutes shall be provided to the building official prior to the pouring of the slab, and the
<br />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
<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 R318.1.1 through R318.1.6 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 Penetration.
<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 (0.25 mm),
<br />and be sealed within the slab using a noncorrosive 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 nonpreservative treated or non -
<br />naturally durable wood, or other cellulose -containing material prior to concrete
<br />placement.
<br />Exception: Inorganic material manufactured for closing cells in foundation concrete
<br />masonry unit construction or clean earth fill placed in concrete masonry unit voids
<br />below slab level before 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 or other veneer which is poured
<br />integrally with the concrete foundation. No supplemental concrete foundation pours
<br />which will create a hidden cold joint shall be used without supplemental treatment in
<br />the foundation unless there is an approved physical barrier. An approved physical
<br />barrier shall also be installed from below the wall sill plate or first block course
<br />horizontally to embed in a mortarjoint. If masonry veneer extends below grade, a
<br />termite protective treatment must be applied to the cavity created between the veneer
<br />and the 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 5/TMS 402, provided at least a 6 inch (152
<br />mm) clear inspection space of the foundation sidewall exterior exist between the
<br />veneer and the top of any soil, sod, mulch or other organic landscaping component,
<br />deck, apron, porch, walk or any other work immediately adjacent to or adjoining the
<br />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 structure sidewall,
<br />whether by underground piping, tail extensions or splash blocks. Gutters with
<br />downspouts are required on all buildings with eaves of less than 6 inches (152 mm)
<br />horizontal projection except for gable end rakes or on a roof above 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
<br />the building not occupied by basements.
