. HOW TO USE Surface Preparation - - Concrete: Surface must be clean and sound. It may be dry, ~~ damp, or wet, but free of standing water. Rcrove dust, laitance, grease, curing compounds, impregnations, waxes, foreign particles, and disintegrated materials by mechanical abrasion methods such as sandblasting. Stecl: Sandblast to appropriate finish. Proportioning / Mixing - - Volumetric ratio of Sikadur Hi-Mod is 1:1 (B:A). To mix, proportion 1 part B and l\ parts A into clean pail. Mix thoroughly for 3 minutes with Sika paddle on low-speed (400- to 600-rpm) drill until blend is a uniform straw color. Mix only that amount of Hi-Mod that you can use in 25 minutes at 73F. Application - - To prepare a grout to anchor bolts or level base plates, mix Hi-Mod with Sikadur Granules. The amount of granules used should be the maximum amount possible while still maintaining a pourable consistency. The ratio should be approximately 1:13; by loose volume (Hi-Mod: Granules). See technical bulletin on anchor bolt grouting and grouting base plates. LIMITATIONS Do not thin Stkadur Hi-Mod! Solvents will prevent proper cure. Use only even-dry granules to avoid encapsulation of moisture. Exposure to temp-eratures (after cure) above 180F (dry) and 120F (wet) not recommended. Substrate temperature must not be below'40F. CAUTION A COMPONENT - For Industrial Use Only! Warning! May cause skin sensitization or other allergic responses. Avoid inhalation of vapor. Use good ventilation partic-ularly if material is heated or sprayed. Prevent all contact with skin or eyes. If contact with skin occurs, wash immediately with soap and water. In case of con-tact with eyes, flush immediately with water and contact a physician. SPI Class 4. B COMPONENT - DANGER! CAUSES (SEVERE) BURNS. Contains alkaline amines strong sensitizer. Do not get.in eyes, on skin, on clothing. Avoid breathing vapor. Keep container closed. Use with adequate ventilation. Wash thoroughly after handling.

Surface Preparation - - Concrete: Surface must be clean and sound. It may be dry, damp, or wet, but free of standing water. For sealcr application, substrate must be dry. Remove dust, laitance, grease, curing compounds, impregnations, waxes, q foreign particles, and disintegrated materials by mechanical abrasion methods. 1 Steel: Sandblast to appropriate finish. Propertioning/ Mixing - - The volumetric ratio of Lo-Mod LV is 1:2 (B:A). To mix, proportion 1 part B and 2 parts A into clean pail. Mix thoroughly for 3 minutes with Sika paddle on low-speed (400- to 600-rpm) drill. Mix only that amount of Lo-Mod LV that you can use in 25 minutes at 73F. Mortar - - To prepare Sikadur Lo-Mod Lv epoxy mortar, slowly add approximately 3 parts by loose volume of Colma Quartzite Aggregate to premixed Lo-Mod LV while continuing to mix to a uniform consistency. Application - - Impregnation - Apply mixed Lo-Mod LV with rubber squeegee or roller to dry substrate. Allow time to penetrate. Squeegee off excess while it is still liquid. Spalled areas - Prime with Lo-Mod LV. Apply with broom, brush, or \-in.- nap rollers. Pour mixed Lo-Mod LV into large, clean pail. Add Colma Quartzite Aggregate (approximately 3 parts by loose volume) while slowly continuing to mix to uniform consistency. Apply mortar while prime coat is still tacky. Use temp-orary or permanent screeds to strike off and level. Finish with steel trowel. Occasionally wipe trowel lightly with water-dampened rag for smooth finish. A sealer coat of Lo-Mod LV should be applied for optimum results. LIMITATIONS Do not thin Sikadur Lo-Mod LV. Solvents will prevent proper cure. Not designed for use as an adhesive for fresh plastic portland-cement mortar or concrete. Use Sikadur Hi-Mod. . Use only oven-dry aggregate to avoid encapsulation of moisture. Exposure to temp-eratures (after cure) above 180F (dry) and 120F (wet) not recommended. Substrate temperature must not be below 40F. CAUTION A COMPONENT - For Industrial Use Only! Warning! May cause skin sensitization or other allergic responses. Avoid inhalation of vapor. Use good ventilation partic-ularly if material is heated or sprayed. Prevent all contact with skin or eyes. If contact with skin occurs, wash immediately with soap and water. In, case of con-tact with eyes, flush immediately with water and contact a physician. SPI Class 2. B COMPONENT - DANGER!

WATERFORD SES UNIT NO. 3 CONCRETE REPAIRS FOR PLACEMENT 499502-10B The repair procedure for mat placement 10B, section 9.6, dcals with waterproofing the repaired area. The extent of the waterproofing should , be such that the entire length of the west face of placement 10B be water-proofed using W. R. Grace's bituthene to a depth as shown on the attached sketch. This will require excavating a trench along the side of the foundation mat, preparing the surface and applying the waterproofing membrane according to Ebasco specification LOU-1564.475. An additional 12 inches of the waterproofing membrane with a bead of bitothene mastic should ba installed around all edges. It should be also made clear that the repair of the voids on the west face of placement 10B be made prior to concreting wall placements 565-1A, 499S04- < 4A-1 and 499504-8A-1. These walls are exterior walls located above the voids. The concrete being used to repair these voids should also be allowed to reach design strength before these walls are placed. i EJG/11 Enclosure ec: A. A. Ferlito (w/ encl) . A. H. Wern (w/ enc 1) P.
