Non-shrink Non-metallic Grout

SC Multipurpose Grout is a versatile, non-shrink, and non-metallic cement-based grout, engineered for a wide array of grouting needs. Its design allows for application consistency ranging from damp pack to flowable, enabled by controlled, positive expansion.

  • Provides controlled positive expansion for optimal load bearing.
  • Non-metallic and non-corrosive.
  • Suitable for pouring or pumping.
  • Excellent freeze/thaw durability.
  • Can be extended with pea stone for deep fills.
  • Matches natural concrete color.
  • Supports LEED credit achievement.
  • User-friendly, just add water.
  • Free of chlorides and gypsum.
  • USDA accepted.

Application

Surface Preparation

  • Cleaning the surface:Remove all dirt, oil, and any loose or foreign materials.
  • Metal surfaces:Ensure they are free from rust, oil, grease, and other contaminants.
  • Conditioning the surface:Ensure the concrete surface is sound and roughened (CSP 3 or greater).Achieve a saturated surface dry (SSD) state for at least an hour before grouting.Remove excess water prior to grout application.
  • Securing the area:Bolts, base plates, and equipment should be securely fastened.
  • Temperature management:Ensure all materials and surfaces are within 50°80°F.
  • Form preparation:Design forms to allow continuous grout placement with venting to prevent air entrapment.Ensure a minimum of 1” horizontal clearance around the base plate.Forms should be 1” higher than the base plate’s bottom.

Mixing and Application

  • Mixing:For small quantities, mix manually until lump-free.For larger volumes, use a mortar mixer with rubber-tipped blades or an appropriate grout pump.Mix for at least 5 minutes.Begin mixing with minimal water, adding the grout powder to achieve the desired consistency.
  • Application:Execute a continuous and swift placement to avoid air pockets.Ensure the grout thoroughly occupies the spaces and maintains contact with the base plate.Do not vibrate the grout.Apply the grout up to the bottom of the base plate only.

Curing Process

  • Wet curing:Initiate immediately after grout placement until the final set.
  • Final curing:Use a SpecChem ASTM C309 compliant curing compound after the final set.

Special Conditions

  • Deep applications:Use pre-washed 3/8” pea gravel for applications exceeding 3” in depth.

Packaging

Available in 50 lb bags, yielding approximately 0.45 cu. ft. in fluid condition. An addition of 50% by weight of 3/8” pea stone increases yield to approximately 0.59 cu. ft.

Shelf Life

Store in a cool, dry place. When kept in its original, sealed container, shelf life extends to one year from the manufacture date.
