Shrinkage ASTM D1042-01a <4 percent

2.2 DRY OAKUM

Dry oakum used for joint stopping shall be as recommended by the chemical grout manufacturer. It must be made from thoroughly carded jute fiber that is free from hard, coarse fibers and extraneous matter. Dry oakum must be manufactured in rope form with at least eight strands having a twist of approximately 1.25 turns per foot. Rope must be approximately 2-inches in diameter and weigh approximately 0.4 lbs. per foot and must be made such that it is possible to strip away jute fibers of smaller diameter as necessary to fit monolith joints of varying widths. Dry oakum must conform to Federal Specification HH-P-117 as published in the Federal Standard Stock Catalog, Section IV, Part 5.

SECTION 03 62 16.00 28 Page 4

2.3 CLOSED-CELL BACKER ROD

2.4 MIXING WATER

Provide clean potable water complying with NSF/ANSI 60.

(NOTE: Only non-potable water will be available on site at the John Day Project.)

PART 3 EXECUTION

3.1 REMOVAL OF OLD SEALANT AND CLEANING OF JOINTS

Old joint sealant, joint backer, spalled concrete, rust and dirt must be completely removed from the existing horizontal joints to receive chemical grout. Open joints that are contaminated with grease or oil must be cleaned with a solvent approved by the chemical grout manufacturer.

Application of solvent shall be by means of clean, dry rags. Pouring solvent directly onto grease and oil contamination will not be allowed.

After removal of all old sealant and foreign material from a monolith joint, it must be vacuumed to remove all loose waste material or the joint must be blown clean with compressed air to remove all loose material. At the approval of the Government, high pressure water may be used for final joint cleaning where non-water cleaning methodologies do not provide adequate results. Before using high pressure water cleaning, the Contractor must prepare and submit a written plan for conducting the cleaning and mitigating water intrusion into the Powerhouse and adjacent galleries of the dam. If high pressure water cleaning is used, the Contractor must be fully responsible for immediately mopping up any water that gets inside the Powerhouse and adjacent galleries of the dam. The Contractor must also be fully responsible for repairing or restoring any Powerhouse equipment and finishes that are damaged by the water intrusion.

All cleaned joints must be inspected and approved by the Government before beginning grout installation.

3.2 SEALING HORIZONTAL JOINTS

3.2.1 Sealant Injection Timeframe

To ensure the chemical grout system maintains a watertight seal throughout seasonal cycles of expansion and contraction, it must be installed at the anticipated mid-point of joint movement. It is estimated that this will occur at John Day Dam in the early spring. Thus, as long as all required environmental conditions for installation are met, the Contractor must plan on injecting the chemical grout during this timeframe. Notify the COR of any delays necessary due to unsuitable installation conditions.

3.2.2 Installing Closed-Cell Backer Rod

Before installation of the closed-cell backer rod at the top of the monolith joints, ensure the joint is clear of all excess joint stopping material that may interfere with a uniform and complete application of the hydrophilic joint filling polyurethane grout. After cleaning, compress the closed-cell backer rod into the top of monolith joints to the depth indicated on the drawings. Ensure the backer rod is continuous in the

SECTION 03 62 16.00 28 Page 5 joint with no breaks or gaps.

3.2.3 Injecting Chemical Grout

As far as practicable, concrete must be wetted per the polyurethane grout manufacturer's recommendations before the grout is injected into the joint. Leave the tips off all of the injection ports that do not have grout in them to allow air and water to vent out of the joints. Pump the hydrophobic polyurethane resin into the injection ports by using increasing pressure to ensure the grout completely fills the joint. Do not increase the application pressure beyond that necessary to achieve grout flow through the joint. Strictly follow the manufacturer's recommendations for application during extreme temperatures.

3.2.4 Patching the Injection Holes

After grouting is complete, patch the injection holes to a minimum depth of 2 inches. The patching material must be an epoxy gel as recommended by the chemical grout manufacturer.

3.2.5 Removing Excess Grout and Cleaning

Remove excess chemical grout with scraping knives, grinding wheels or wire wheels. Removal and cleaning methodologies must minimize damage to existing concrete and steel finishes on the intake deck. A solvent recommended by the chemical grout manufacturer must be used to clean chemical grout from surfaces to receive the trafficable sealant system (See specification SECTION 07 18 00.00 28).

3.3 PROTECTION AND CURING

Protect freshly placed grout from premature drying and excessive cold or hot temperatures. Comply with manufacturer's requirements for cold-weather and hot-weather protection during curing. Additionally, new grouting work must be protected from foot and vehicle traffic until installation of the trafficable sealant system (See SECTION 07 18 00.00 28).

PART 3 EXECUTION

3.1 PREPARATION

3.1.1 Preparation of Existing Surfaces

Ensure that substrates are free from large irregularities, loose, unsound or foreign material such as dirt, ice, snow, water, grease, oil, bituminous products, old elastomeric sealant, laitance, paint, loose particles/friable matter, rust or any other material that would be detrimental to adhesion of the catalyzed primer and/or resin to the substrate. Shot blast or scarify existing concrete surfaces to provide a sound substrate free from laitance, carbonated concrete, asphalt or coal tar bitumen or old sealant elastomeric sealant. Generate a concrete surface profile of CSP-2 to CSP-4 as defined by the ICRI. Grinding may be used as a preparation method for localized areas that cannot be reached by shot blasting equipment provided that a surface profile of CSP-2 to CSP-4 can be achieved. Repair concrete spalls and voids using the specified primer and preparation paste.

3.1.2 Protection of Installed Chemical Grout

During all polyurethane waterproof system installation, take care and precautions as necessary to not disturb the newly installed chemical grout in joints. Any damage caused to installed chemical grout must be repaired before continuation of work.

3.1.3 Adhesion Testing for Substrates to Receive the Waterproof System

a. Tests to determine tensile bond strength of the polyurethane waterproof system to the concrete and steel substrate must be conducted by the Contractor at the job site using an Elcometer Adhesion Tester Model 106 or similar device in accordance with ASTM D4541. Contractor must perform tests at the beginning of the Work, and at intervals as required to assure specified adhesion with a minimum of three tests.

Test results must be submitted to the Government and the polyurethane waterproof system manufacturer. Contractor must immediately notify the Government and manufacturer in the event tensile bond test results are below specified values.

b. Adequate surface preparation will be indicated by tensile bond strength of membrane to substrate greater than or equal to 220 psi (1.5 N/mm2).

c. In the event the tensile bond strengths are lower than the minimum specified, additional substrate preparation is required. Repeat testing to verify suitability of substrate preparation.

3.1.4 Repair and Leveling of Concrete

Before application of the polyurethane waterproof system primer, fill all of the monolith joints above the newly installed top backer rod as well as all cracks, voids, fractures, depressions, small indentations and low areas in the concrete substrate using epoxy patching material as approved by the waterproof system manufacturer. Allow the leveling material to cure before beginning installation of the waterproof system.

3.1.5 Joint Sealant

Seal the tops of monolith joints that have been filled with the hydrophobic

SECTION 07 18 00.00 28 Page 10 polyurethane grout with a two component polyurethane sealant. Mix and apply the sealant in accordance with manufacturer instructions.

3.1.6 Primer Application

Prime horizontal and vertical concrete surfaces to receive the polyurethane waterproof system, but do not prime over polyurethane sealant used to seal the tops of joints. Apply primer at the rate and with the installation methodology complying with the manufacturer's instructions.

3.2 SPECIAL PRECAUTIONS

Protect waterproofing materials during transport and application. Do not dilute primers and other materials, unless specifically recommended by materials manufacturer. Keep containers closed except when removing contents. Do not mix remains of unlike materials. Thoroughly remove residual materials before using application equipment for mixing and transporting materials. Do not permit equipment on the project site that has residue of materials used on previous projects. Use cleaners only for cleaning, not for thinning primers or the waterproofing materials. Ensure that workers and others who walk on the cured waterproofing system wear clean, soft-soled shoes to avoid damaging the waterproofing materials.

3.3 APPLICATION

Closely follow the Membrane Manufacturer's recommendation for hot and cold weather application. Monitor surface and ambient temperatures, including the effects of wind chill. Apply mixed resin to the prepared surface in accordance with the following specifications and in accordance with manufacturer's written instructions and details where specifically referenced in this specification. Where there is a conflict between the procedures contained in this specification section and written manufacturer instructions, the stricter of the two sets of criteria must be followed.

3.3.1 Application Timeframe

To ensure the polyurethane deck coating system maintains continuity and a watertight seal throughout seasonal cycles of expansion and contraction, it must be installed at the anticipated mid-point of joint movement. It is estimated that this will occur at John Day Dam in the early spring. Thus, as long as all required environmental conditions for installation are met, the Contractor must plan on applying the deck coating during this timeframe. If temperature and moisture conditions during this time are unsuitable for meeting the required environmental restrictions for installation, then the Contractor may delay the application until an acceptable window of good weather conditions becomes available. Notify the COR of any delays necessary due to unsuitable installation conditions.

3.3.2 Application of Base Coat

Wipe primed surfaces with the specified cleaner/solvent. Allow the surface to dry a minimum 20 minutes before continuing work. Mix A and B components of the base coat as recommended by the manufacturer. Apply the base coating on horizontal and vertical concrete surfaces as indicated on the drawings. Using a properly notched squeegee, apply the base coating over the primed substrate at the minimum rate specified by the manufacturer.

Backroll the base coating with a spiked roller to remove any air bubbles.

Allow the base coating to cure three to four hours before application of the intermediate coat of polyurethane.

SECTION 07 18 00.00 28 Page 11

3.3.3 Application of Intermediate Coat and Aggregate

Apply the intermediate coat over the cured base coat with a roller at the rate recommended by the manufacturer. While the intermediate coating is still wet and before it skims over, broadcast the approved silica aggregate into it. Apply the aggregate only on horizontal and use a sufficient amount of aggregate to ensure good slip resistance and suitable wear-resistance for light vehicle traffic. Lightly backroll the aggregate immediately after application. Allow the aggregate intermediate coat to cure three to four hours before application of the top coat. After curing and before application of the polyurethane top coat, sweep or vacuum up all loose silica aggregate.

3.3.4 Application of Topcoat

Apply the top coat over the cured intermediate coat with a roller at the rate recommended by the manufacturer. Lightly backroll the coating to ensure it is uniform and level. Allow a minimum 24 hours of curing before before allowing vehicular traffic onto the coating.

3.3.5 Interruption of Work

If work is interrupted for more than 12 hours, or the surface of a coating becomes dirty or contaminated from exposure to the elements, thoroughly clean the area with the cleaner/solvent before continuing with the application work. Allow a minimum of 20 minutes for the solvent to evaporate before restarting the application work. Complete the next application procedure within 60 minutes following evaporation of the cleaner/solvent.

3.4 FIELD QUALITY CONTROL

3.4.1 Moisture Test

Prior to application of polyurethane waterproofing system, measure moisture content of substrate with a moisture meter in the presence of the Contracting Officer. An acceptable device is the Delmhorst Moisture Meter, Model BD7/2E/CS, Type 21 E. Similar meters by other manufacturers, which are suitable for the purpose, may be used as approved by the Government.

Do not begin application until meter reading indicates "dry" range.

3.4.2 Film Thickness

Measure wet film thickness every 100 square feet during application by placing flat metal plates on the substrate or using a mil-thickness gage especially manufactured for the purpose.

3.4.3 Warranty Inspection and Issuance

Upon completion of work, schedule a final inspection by the polyurethane waterproof system manufacturer technical representative pursuant to issuance of the manufacturer 10-year material warranty. The Government must be notified at least 10 working days in advance of the manufacturer inspection. A punch list of items required for completion or reworking must be compiled by the Contractor and the manufacture's technical representative. A copy of the list must be provided to the Government and all items must be completed prior to issuance of the warranty.

SECTION 07 18 00.00 28 Page 12

3.5 INSTRUCTIONS TO GOVERNMENT PERSONNEL

Furnish written and verbal instructions on proper maintenance procedures to the Government. Furnish instructions by a competent representative of the polyurethane waterproof system manufacturer and include a minimum one hour training session on maintenance and emergency repair of the waterproof system. Include a demonstration of system repair, and give sources of required special tools. Furnish information on safety requirements during maintenance and emergency repair operations.
