SC Precision Grout HS Green Conscious Product

High performance/high-strength grout

SC Precision Grout HS is a high-performance, non-metallic, cementitious grout that achieves high early and ultimate compressive strength. It is specifically designed for high strength precision grouting applications including compressors, heavy equipment foundations, and tank bases. This grout mixes into a flowable, pumpable consistency and provides effective load bearing.

  • High Compressive Strength: Achieves high early and long-term strength for demanding applications.
  • Non-Shrink/Non-Corrosive: Ensures structural integrity and longevity without damaging reinforcement.
  • Versatile Application: Suitable for both interior and exterior environments exposed to heavy loads or vibrations.
  • Excellent Freeze/Thaw Resistance: Ensures durability under varying temperatures.
  • Extended Use: Can be bulked up with pea gravel for deeper applications.
  • Compliant with Standards: Meets ASTM C1107, Grades A, B, & C, and CRD C-621 Grades A, B, & C.

Application

Surface Preparation

  • Clean surface: Ensure the area is free from dirt, oil, and any loose or foreign materials.
  • Metal surfaces: Must be free from rust, oil, grease, and other contaminants.
  • Concrete surface preparation:
    • Ensure the surface is sound and roughened to enhance bonding.
    • Achieve a saturated surface dry (SSD) state if possible for at least one hour before grouting.
    • Remove all excess water prior to grout application.
  • Secure components: Bolts, base plates, and equipment should be securely fastened and stable.
  • Temperature control: Ensure materials and surfaces are within 50°-80°F for optimal performance.
  • Form setup: Create forms for continuous grout placement with venting measures to prevent air entrapment.
    • Ensure at least 1” of horizontal clearance around the base plate.

Mixing and Application

  • Mixing process:
    • For single-bag quantities, use a heavy-duty drill/mixer in a 5-gallon pail.
    • For larger amounts, use a mortar mixer with rubber-tipped blades or an appropriate grout pump.
    • Use 5.5 pints of water per 50 lb bag; do not exceed 5.75 pints.
    • Begin mixing with minimal water, adding the grout powder to the mixing water.
    • Mix for 3-4 minutes, allow a 30-second induction period, then mix for an additional minute.
  • Grout placement:
    • Ensure continuous and rapid placement to minimize air entrapment.
    • Maintain at least 1” of vertical clearance for base plate grouting applications.

Curing

  • Initial curing: Cover the grout with clean, wet rags immediately after placement until the final set is achieved.
  • Final curing: Apply an ASTM C309 compliant curing compound.

Special Conditions

  • Deep applications: For depths over 3”, incorporate pre-washed and graded 3/8” pea gravel.

Packaging

  • Available in 50 lb bags, yielding approximately 0.42 cubic feet in a fluid condition. It can be extended with pea stone for larger volume needs.

Shelf Life

  • Store SC Precision Grout HS in a cool, dry interior area. The product has a shelf life of one year when stored properly in its original, tightly closed container.
