Concrete shall be placed to avoid the displacement of reinforcing, and coating or spattering the reinforcing steel. The placing of concrete within form work shall be regulated so that the pressure within form work does not exceed the design pressure. In placing concrete, each layer shall be placed following the preceding layer to prevent lines of separation or "cold joints" in the work. After the concrete reaches its initial set, jarring the formwork or placing strain or vibration on the ends of projecting reinforcing bars shall be carefully avoided. C. Once concreting is started, it shall be carried on as a continuous operation until placing of the concrete between construction joints is completed. The top surface will be finished to the required alignment. D. Concrete shall be placed in layers not over 12-inches deep and each layer shall be compacted with the aid of mechanical internal-vibrating equipment supplemented by hand spading. Vibrators shall in no case be used to transport concrete. Use of form vibrators will not be permitted. Internal vibrators shall maintain a speed of not less than 5,000 impulses per minute when submerged in the concrete. Duration of vibrator use shall be limited to that necessary to produce satisfactory consolidation without causing objectionable segregation. Vibrator shall not be lowered into courses that have begun to set. Apply vibrator at uniformly spaced points not further apart than the visible effectiveness of the machine. E. Type and use of vibrators shall be in accordance with ACI 301. 3.11 PROTECTION A.

Ambient or substrate temperatures are less than 45F or more than 90F or if the substrate temperature is less than 5F above the dew point at the time of application. 2. Rain is forecasted within 24 hours. B. The primary concrete or masonry surface must be cured a minimum of twenty-eight days before the application of the water-repellent sealer. C. Prior to and during application of the water-repellent sealer, the concrete or masonry surface must be completely dry with a minimum moisture content of 4%, as tested with a moisture meter. D. Protect adjacent building surfaces (e.g.; window frames, glass) and landscaping by masking to protect from overspray. Any product spilled or dripped on an unwanted surface should be immediately removed by wiping with a clean cloth dipped in detergent solution and rinsed with clean water. PART 2 – PRODUCTS 2.01 MATERIALS A. Water-Repellent Sealer: Thin coat, liquid applied, hydrophobic, impregnating water-repellent clear sealer consisting of a silane/siloxane aqueous emulsion designed for use on concrete or masonry substrates with 0.5% maximum water absorption with 48 hrs exposure as tested in accordance with ASTM C642; Ghostshield Siloxa-Tek® 8500 as manufactured by KreteTek Industries, Inc. Mayo Wheel Wash Improvements CONCRETE MASONRY SEALER Golder Associates NC Inc. February 2017 03719-3 Project No. 1533278 2.02 MANUFACTURER B. KreteTek Industries, Inc. 1000 N West St Wilmington, DE 19801 (855) 573-8383 Website: http://ghostshield.com PART 3 – EXECUTION 3.01 GENERAL WORKMANSHIP FOR WATER-REPELLENT SEALER A. Comply with all recommendations of the manufacturer of the water-repellent sealer for surface preparation and installation of the sealer. B. Perform a test application on each type of surface prior to full-scale application to determine suitability and final appearance. C. Measure and record site conditions immediately before (as applicable) and periodically during the installation of the water-repellent sealer. Measurements must include air and substrate temperatures, air and substrate relative humilities, application rate, and record general notes on product uptake and performance. 3.02 PREPARATION OF CONCRETE OR MASONRY SURFACES FOR WATER REPELLENT A. Check concrete or masonry surfaces to ensure that they are suitable for application of water- repellent sealer. Treat unsuitable surfaces (too smooth, too rough, not dry, or contaminated by dirt, oil or any coating or other impurities) as required to make them suitable for application of sealer. 1. Remove all dirt, dust, or other foreign matter from the surface of the concrete or masonry prior to the application of the water-repellent sealer using methods described in this section and approved by ENGINEER based on surface preparation mockups. 2. After cleaning, if a wet method such as power washing is used, the concrete or masonry surface must be allowed to dry for not less than 24 hrs before the application of the water- repellent sealer. If good weather conditions conductive to drying are not present, a longer drying time should be allowed and the sealer should not be applied until the concrete or masonry is completely dry as described in this section. Use a moisture meter if necessary to monitor drying of the concrete or masonry. B. Concrete or masonry substrates must be structurally sound, thoroughly dry, clean, and cured at least twenty-eight days. C. If acid or chemical cleaning agent is used to clean the concrete, make sure to neutralize before sealing. 3.03 WATER-REPELLENT SEALER APPLICATION A. Apply water-repellent sealer to prepared substrates within three days after completion of the surface preparation. Mayo Wheel Wash Improvements CONCRETE MASONRY SEALER Golder Associates NC Inc. February 2017 03719-4 Project No. 1533278 B. Stir and mix materials thoroughly to ensure uniformity and in accordance with the manufacturer’s recommendations. C. Apply water-repellent sealer with a sprayer or roller. 1. Application rate depends on the density of the concrete or masonry and the depth of penetration required. Apply the sealer, liberally to the surface of the concrete or masonry to achieve high penetration depth but no more than what can stay on the surface without run off. 2. For typical first coat applications, apply one coat of sealer at a rate of approximately 250 sq ft per gallon; application rate specific to the project determined by the mockup. 3. Apply a second coat wet-on-wet, or immediately after the first coat. Take care to avoid the product running or dripping off the substrate. Broom out puddles until they soak in. Do not over apply. D. It may take up to 2 or more hours for the sealer to completely penetrate if the substrate is of high density. The treated surface may remain dark for up to twenty-four hours before it returns to normal appearance. E. Do NOT apply the sealer to concrete or masonry surfaces: 1. That are damp or have damp repairs. If rain suddenly begins during installation, immediately stop application of sealer and cover the newly impregnated areas. 2. If the conditions (e.g.; weather or surface conditions) do not meet the requirements of Para. 1.06 above or are not expected to meet the requirements for any time within a 24 hr period after installation. F. Do not disturb sealed surfaces for a minimum of 6 hrs after the application of the product. Early water repellence with be developed after 24 hrs; however, full curing of the sealer may take up to seven days or longer. Do not install concrete or masonry repairs for a minimum of 72 hrs after application of the sealer. * * * END OF SECTION * * *
