SpecRock Anchoring Cement & Non-Shrink Grouting Solutions

SpecRock is a fast-setting, non-shrink anchoring cement designed for securing bolts, reinforcing steel, railings, posts, machinery, and structural components into concrete. This one-component Portland cement-based anchoring material expands as it cures, helping create a secure mechanical bond within the surrounding concrete. SpecRock is waterproof, freeze-thaw resistant, and suitable for both interior and exterior applications.

Fast-Setting Anchoring Cement

SpecRock develops strength rapidly and typically sets hard within approximately 12 to 15 minutes, allowing contractors to complete anchoring applications quickly while minimizing downtime. An extended-set version is also available for hot-weather applications where additional placement time is required.

Benefits of Fast-Set Anchoring Cement

• Reduced project downtime
•  Quick setting; sets hard in 12-15 minutes; speeds production
• Rapid high strength up to 2000 psi. in 1 hour at 7
• Faster installation schedules
• Rapid strength development
• Improved productivity
• Suitable for commercial and industrial projects

Concrete Anchoring Applications

SpecRock is designed for anchoring a variety of structural and mechanical components into concrete.

Common Uses Include

• Anchor bolts
• Reinforcing bars
• Handrails
• Guardrails
