One 50 lb (22.7 kg) bag of SikaGrout®-4316 grout mixed with approximately 6 lbs. (2.7 kg) or 0.72 gallons (2.72 L) of water provides approximately 0.39 ft³ (0.011 m³) of grout.
Note: The water requirement may vary due to mixing efficiency, temperature, and other variables.

• Contact your local representative for a pre-job conference to plan the installation.
• Large, exposed areas of grout should be avoided.
• The structural integrity of the grout is not affected by superficial, hairline cracks occasionally observed in shoulders, near base plate edges, and around anchor bolts.
• Mix times closer to 5 minutes have resulted in better compressive strength development and working time.
• When grouting at minimum temperatures, see that the foundation, plate, and grout temperatures do not fall below 35 °F (2 °C) until after the final set. Protect the grout from freezing (32 °F or 0 °C) until it has attained a compressive strength of 3,000 psi (21 MPa) in accordance with ASTM C 109.
• Low temperatures delay the set, increase working time, and delay the strength development. High temperatures accelerate the set, decrease working time, and accelerate the strength gain. The procedures below help compensate for this. In light of this, store and mix grout to produce the desired mixed-grout temperature. If bagged material is hot, use cold water, and if bagged material is cold, use warm water to achieve a mixed-product temperature as close to 70 °F (21 °C) as possible.
• Should not be used as a floor topping
• If placing material in skid-mounted applications with deep cavities, contact your local Sika representative
• Make certain the most current versions of the product data sheet and SDS are being used.
• Proper application is the responsibility of the user. Field visits by Sika personnel are for the purpose of making technical recommendations only and not for supervising or providing quality control on the jobsite.

1. Steel surfaces must be free of dirt, oil, grease, or other contaminants.
2. Cure the foundation until the design strength of the concrete is achieved and the foundation is dry. Use the recommended procedure according to ACI 351.1R, Grouting Between Foundations and Bases for Support of Equipment and Machinery. In lieu of mechanical surface preparation, surface retarders may be used on freshly placed concrete. Remove surface retarder after 24 hours by use of pressure washing to achieve an exposed aggregate finish. After pressure washing, regular curing practices should continue until design strength is reached.
3. The surface to be grouted must be clean, SSD, strong, and roughened to a CSP of 5–10 following ICRI Guideline 310.2 to permit proper bond.
4. When dynamic, shear, or tensile forces are anticipated, concrete surfaces should be chipped with a “chisel-point” hammer, to a roughness of (plus or minus) 3⁄8" (10 mm). Verify the absence of bruising following ICRI Guideline 310.2.
5. Concrete surfaces should be saturated (ponded) with clean water for 8 hours or more depending on site conditions, prior to grouting.
6. All freestanding water must be removed from the foundation and bolt holes immediately before grouting.
7. Anchor bolt holes must be grouted and sufficiently set before the major portion of the grout is placed.
8. Shade the foundation from sunlight 24 hours before and 24 hours after grouting.

1. Condition and maintain the grout and surfaces that contact the grout between 35 to 100 °F (2 to 38 °C) for mixing, placing, and curing.
2. Place estimated water (Use potable water only) into the mixer, then slowly add the grout. Start with 5.75 lbs. (2.6 kg) or 0.70 gallons (2.61 L) per 50 lb bag.
3. The water demand will depend on mixing efficiency, material, and ambient temperature conditions. Adjust the water to achieve the desired flow. The recommended flow is an 8–10" spread using a 2" diameter x 4" height plastic tube (such as PVC pipe) on a non-porous, level surface. Use the minimum amount of water required to achieve the necessary placement consistency. Do not exceed 6.25 lbs. (2.84 kg) or 0.75 gallons (2.84 L) of water per 50 lb bag.
4. Provide one or more clean mortar mixers (stationary barrels with moving paddles) for uninterrupted placement. Do not exceed one-half the maximum capacity. Pre-wet the mortar mixer, and empty excess water prior to use.
5. Mix grout for at least 4 minutes and no longer than 6 after all material and water is in the mixer until a homogenous consistency is achieved. Use a mechanical mixer only.
6. Transport by wheelbarrow or buckets or pump to the equipment being grouted. Minimize the transporting distance. Do not mix more material than can be placed within the working time of the grout. If grout stiffens as it sits, remix with a mechanical mixer to keep it flowable.
7. Do not retemper grout by adding additional water after it stiffens.
8. Do not add plasticizers, accelerators, retarders, or other additives.

1. Always place grout from only one side of the equipment to prevent air entrapment beneath the equipment. A headbox or similar device is required for a continuous pour to avoid air pockets. When pouring into the headbox, maintain at least half full of grout to ensure even flow. Discard grout that becomes unworkable. Make sure that the material fills the entire space being grouted and that it remains in contact with the plate throughout the grouting process.
2. Do not vibrate grout. Use steel straps inserted under the plate to help move the grout.
3. The minimum placement thickness is 1" (25 mm). Consult your Sika representative before placing lifts more than 6" (152 mm) in depth.
4. Immediately after placement, trim the surfaces with a trowel and cover the exposed grout with clean wet rags (not burlap). Keep rags moist until the grout surface is ready for finishing or until the final set.
5. The grout should offer stiff resistance to penetration with a pointed mason’s trowel before the grout forms are removed or excessive grout is cut back.
6. Proper application is the responsibility of the user. Field visits by Sika personnel are for the purpose of making technical recommendations only and not for supervising or providing quality control on the jobsite. For guidelines on specific anchor bolt applications, contact Sika Technical Services.

Cure all exposed grout with an approved membrane curing compound compliant with ASTM C 309 or preferably ASTM C 1315. Apply the curing compound immediately after the wet rags are removed to minimize potential moisture loss.
