The plaza deck pavement shall be constructed using architectural paving slabs from an acceptable manufacturer and the patented SRS Leveling System.
2.02 MATERIALS A. SRS Leveling System: 1. The elevated, open draining paving slab system shall be installed using the patented SRS Leveling System. a. The SRS leveling blocks shall be 60 psi or 100 psi extruded polystyrene foam material. b. Typical SRS leveling blocks shall be 8"x8", 9 5/8" x 9 5/8", or 12"x12". Pedestals 12" or higher shall be 12"x12". Other project-specific pedestal sizes and shapes may be recommended. c. The SRS Leveling System shall use 1/8" or 3/16" neoprene rubber SRS spacing tabs. 2. SRS Leveling System Reference Standards: a. SRS leveling blocks shall conform to the following ASTM standards: ASTM C-78: Specification for polystyrene foam materials ASTM C-203: Specification for polystyrene flexural strength ASTM C-272: Specification for polystyrene minimum moisture absorption ASTM D-1621: Specification for polystyrene compressive strength testing 3. SRS Leveling System Performance Standards: a. SRS leveling blocks shall be 60 psi or 100 psi polystyrene foam. b. SRS leveling blocks shall have a maximum water absorption rate of.3%. d. SRS leveling blocks shall have a flexural strength of 75 psi. B. Polystyrene Adhesive: 1. SRS leveling system adhesive shall be (Chemrex/Ohio Sealant) PL300, QB300, PL Premium or approved equal as necessitated by compatibility requirements with the immediately underlying substrate. C. Waterproofing System Preparation: 1. Prior to waterproofing, the structural concrete slab and insulation layers must be designed to accommodate anticipated pedestrian loads. 2. All waterproofing, flashing, caulking, insulation, drainage mats and protection board materials, as well as the waterproofing of all deck penetrations, shall be determined and installed in accordance with waterproofing manufacturer's recommendations.
PART 3.00 - EXECUTION 3.01 INSPECTION: A. Examine all surfaces to receive the work specified herein. Verify all dimensions of existing and subsequent construction and compare layout of deck to shop drawings and architect's drawings. All variances of field conditions from drawings shall be reviewed and corrected prior to the installation of the paving slabs. Notify the Contractor in writing of any conditions detrimental to the proper and timely completion of the work. Do not proceed with the work until unsatisfactory conditions have been corrected. 3.02 PREPARATION: A. Barricade or otherwise isolate work area during paving slab installation and sealing. Keep barricades in place until the entire pavement is fully installed and complete. B. Lay out pattern in straight courses, symmetrical about centerlines and correctly terminated at all edges. Maintain alignment and patterns as shown on plans and details. 3.03 INSTALLATION: A. Preparation: 1. Prior to placing the SRS Leveling System and the concrete paving slabs, remove all foreign materials from the deck. Sweep the protection/insulation layer with a broom to ensure deck is clean. 2. Ensure that all waterproofing, insulation and protection layers are secure and are laying flat with no pumping or movement of the layers from pedestrian traffic. B. General: 1. Paving slabs shall be free from stain, dirt, or dust. 2. Install paving slabs with skilled mechanics and employ skilled fitters at the site for necessary field cutting as units are set. C. SRS Leveling System: 1. Using a laser leveling system, establish and mark the finished elevation of the plaza deck. 2. Establish and mark the top elevation of the SRS leveling blocks by subtracting the nominal thickness of the overlying concrete pavings slabs from the finished elevation of the plaza deck. 3. Identify and transfer the layout of the paving slabs to the top layer of the protection / insulation board. 4. Center and adhere the SRS leveling blocks at the intersections of the X and Y axis. 5. Level the SRS blocks using the patented SRS Leveling System, as per licensor's recommended procedures / installation manual.
6. Transfer paving slab layout to the tops of the leveled SRS blocks. 7. Install SRS spacing tabs at the intersections of the X and Y axis. 8. Place SRS leveling blocks tight against parapets and structural walls. Field cut SRS leveling blocks at the appropriate angle, if required, to accommodate any deck elevation variation at the deck perimeter or at structural walls. 9. Install and level primary and secondary SRS leveling blocks with traversing piece where SRS leveling block locations occur over deck drains, as per licensor's recommended procedures / installation manual. 10. Adjust paving slabs and SRS leveling blocks as per licensor's recommended procedures / installation manual to maintain slab-to-slab tolerance of 1/16" or less. 11. Adjust paving slabs as required to maintain 1/8" or 3/16" +/- 1/16" straight joints. 3.04 CLEANING: A. Remove and replace paving slabs which are chipped, broken, stained or otherwise damaged, and re-set units that rock or do not match adjoining units as specified. Provide new units to match adjoining units and install in the same manner as original units with the same joint spacing to eliminate evidence of replacement. B. After completion of the work, clean exposed surfaces as necessary. If a cleaning solution is used, verify with solution manufacturer that product is compatible with the paver, polystyrene foam, protection board, and waterproofing. Pressure washers, when using higherpressure nozzles, may leave indelible marks on concrete pavers. 3.05 PROTECTION: A. After installation and cleaning, protect work from damage during subsequent construction activities until work is completed. B. At completion of construction work, remove all temporary protection from the site. C. Clean up and remove all debris and equipment. END OF SECTION
