If the walls are exposed to the exterior environment, the waterproofing <br />system shall have a rigid, opaque, and weather-resistant protective covering <br />to prevent degradation of the waterproofing system. The protective covering <br />shall cover the exposed waterproofing and extend a minimum of 6 inches <br />(152 mm) below grade. The protective covering system shall be flashed in <br />accordance with IRC Section R703.8. <br /> <br />R402.1.1.1 Integral foundation insulation requirements Any insulation assembly <br />installed integral to the foundation walls shall be manufactured for that intended <br />use and installed according to the manufacturer’s installation instructions. <br /> <br />R402.1.1.2 Exterior draining foundation insulation requirements Any insulation <br />assembly installed on the exterior of the foundation walls and on the perimeter <br />of slabs-on-grade that permits water drainage shall: <br />be made of water-resistant materials manufactured for that intended use; <br />be installed according to the manufacturer’s installation instructions; comply <br />with either ASTM C578, C612, or Cl029, as applicable; and <br />have a rigid, opaque, and weather-resistant protective covering to prevent the <br />degradation of the insulation’s thermal performance. The protective covering <br />shall cover the exposed exterior insulation and extend a minimum of 6 inches <br />(152 mm) below grade. The insulation and protective covering system shall be <br />flashed in accordance with IRC Section R703.8. <br /> <br />R402.1.1.3 Exterior non-draining foundation insulation requirements Any <br />insulation assembly installed on the exterior of the foundation walls or on the <br />perimeter of slabs-on-grade that does not permit bulk water drainage shall: 1. <br />be made of water-resistant materials manufactured for that intended use; 2. be <br />installed according to the manufacturer’s installation instructions; 3. comply with <br />either ASTM C578 or C1029, as applicable; 4. be covered with a 6-mil <br />polyethylene slip sheet over the entire exterior surface; and 5. have a rigid, <br />opaque, and weather-resistant protective covering to prevent degradation of the <br />insulation’s thermal performance. The protective covering shall cover the <br />exposed exterior insulation and extend a minimum of 6 inches (152 mm) below <br />grade. The insulation and protective covering system shall be flashed in <br />accordance with IRC Section R703.8. <br /> <br />13. 1/2” anchor bolts must be embedded 7” into concrete or grouted cells of masonry <br />units and spaced not more than 72” O.C. and with-in 12” of every corner and <br />splice. If approved anchor straps are used, they must be spaced as per <br />manufactures instructions. <br />14. Provide copy of Geotechnical reports of soils to building dept. for review. <br />15. R403.1.3.1,2,4 Floating (monolithic) slabs for free standing structures must <br />have a thickened edge slab design with a minimum of 12” below finished grade <br />around perimeter. Slabs over 1000 sq. ft. require engineering to be submitted at <br />time of plan review. <br />16. R408. A minimum of a 6 mil vapor retarder to be placed directly beneath <br />concrete slabs on grade. <br /> <br />17. R404.1.4 Floor framing blocking to be in accordance with Section R404. <br />a. R404.1.4 Blocking shall be full depth and three joist spaces in. See table <br />R404.1(1) for blocking spacing. sheathing shall be fastened to blocking in <br />accordance with Table R602.3(1).
