This Section includes the following: <br /> 1. Surface applied crystalline waterproofing treatment. <br /> B. Related Requirements: <br /> 1. Division 09, Section "Paint"for painting of walls with treatment. <br /> 1.2 PERFORMANCE REQUIREMENTS <br /> A. Permeability: <br /> 1. When tested to BS EN 12390-8 or DIN 1048-5 at 0.5 MPa (72.5 psi) for 72 hours, permeability of treated <br /> concrete will be reduced by 51% over untreated concrete. Treated samples were cured for 28 days and <br /> treatment was mechanically removed from samples prior to testing. <br /> 2. Passes USACE CRD C48 when tested at 1.38 MPa (200 psi)for 14 days. Permeability of treated concrete will <br /> be reduced by 90%over untreated concrete. <br /> 3. When tested versus untreated sample to DIN 1048-5 and following 28 day curing period, depth of water <br /> penetration shall be reduced by 75%. <br /> B. Self-Sealing:Autogenous crack sealing of treated concrete for cracks with width of 0.5mm (0.02 inches)or greater <br /> when subjected to hydrostatic pressure of 0.44 MPa(65 psi). <br /> C. Chloride Resistance:When tested to ASTM D1411,the waterproofing treatment shall improve concrete resistance <br /> to chlorides below limits require by ACI 222R and demonstrate chloride ion reduction of 84%at 15 mm penetration <br /> depth and 83%at 10 mm penetration depth; performance shall be verified by independent testing.Treated samples <br /> were cured for 28 days and treatment was mechanically removed from samples prior to testing. <br /> D. Sulfate Resistance: The waterproofing treatment shall improve concrete resistance to sulfates by reducing <br /> permeability without affecting compressive strength; performance shall be verified by independent testing. <br /> E. Potable Water Containment:Products of this Section shall be certified to NSF/ANSI Standard 61 for use with potable <br /> water. <br /> 1.3 SUBMITTALS <br /> A. Product Data: Manufacturer's data sheets on each product to be used, including: <br /> 1. Preparation instructions and recommendations. <br /> 2. Storage and handling requirements and recommendations. <br /> 3. Installation methods. <br /> 1.4 QUALITY ASSURANCE <br /> A. Installer Qualifications: <br /> 1. Contractor performing work under this section providing 5-years experience in the installation of the product. <br /> 1.5 PRE-INSTALLATION MEETING <br /> A. Convene a pre-installation meeting at least 3 days prior to installation of the waterproofing. <br /> B. Attendance:Architect,General Contractor, Electrical, Plumbing,&Masonry Contractor,and Spray Foam Contractor. <br /> C. Agenda: Review installation sequence, safety requirements, and substrate conditions. <br /> 1.6 DELIVERY, STORAGE,AND HANDLING <br /> A. Materials shall be delivered in manufacturer's original containers clearly labeled with manufacturer's name, product <br /> identification, safety information, net weight of contents and expiration date. <br /> B. Material shall be stored in a safe manner and where the temperatures are in the limits specified by the material <br /> manufacturer. <br /> C. Do not use materials stored for more than twenty-four(24)months from date of manufacture. <br /> D. Empty containers shall be removed from site on a daily basis. <br /> ©BOOMERANG DESIGN#1835 07 16 16-1 510 Meadowlands Drive,Hillsborough, NC <br /> ORANGE COUNTY,NC 12/07/18 <br />
