Super Por-Rok® Premium Cement Based Anchoring Cement

SpecRock is a pourable non-shrink Portland cement-based anchoring cement that sets hard in 12–15 minutes

SpecRock is a one-component, waterproof, non-shrink, Portland cement-based anchoring cement that expands as it sets to lock into the surrounding concrete. SpecRock ES (extended set) offers a 60–75 minute work time for placement in hot weather conditions above 90°F.

Features

• Sets hard in 12–15 minutes for fast production
• Rapid high strength — up to 2,000 psi in 1 hour at 72°F
• Controlled expansion locks into surrounding concrete as it sets
• Non-metallic — maintains volume stability over time
• Waterproof and resistant to freeze/thaw cycles
• Flowable and pourable for easy application
• Approved for exterior use and direct water exposure
• SpecRock ES offers 60–75 minute extended work time for hot weather applications above 90°F

Mixing & Installation

Mixing Ratio

• Approximately 15% water by weight
• ~2.3 oz water per 1 lb of product

Mixing Instructions

1. Add clean potable water into mixing container
2. Slowly add powder while mixing
3. Mix to smooth, flowable consistency
4. Avoid overwatering (reduces strength)

Placement

• Pour directly into prepared hole or void
• Ensure full encapsulation of anchor bolt or rod
• Finish slightly above surface to prevent water pooling

---

Surface Preparation

Proper preparation is critical for performance:

• Concrete must be fully cured (minimum 28 days)
• Remove all dust, debris, oil, or laitance
• Pre-dampen hole (SSD condition – saturated surface dry)
• Do not leave standing water in anchor hole
• Use proper washer sizing for bolt load distribution
