Por-Rok® Premium Gypsum Based Anchoring Cement
High-Strength Non-Shrink Anchoring Cement
Por-Rok® Anchoring Cement is a premium gypsum-based, non-shrink, hydraulic anchoring compound designed for securing bolts, rods, railings, machinery, and other embedded hardware into concrete. It is a ready-to-use material that only requires water on site, producing a pourable mix that locks into place with controlled expansion for maximum holding strength.
Once placed, Por-Rok develops rapid strength—often exceeding standard concrete within hours—while maintaining volume stability and a tight bond to surrounding concrete substrates. Its non-metallic composition helps prevent corrosion of embedded steel components.
Key Features & Benefits
High Early Strength
Reaches strong working strength quickly, often exceeding conventional concrete within hours of installation.
Non-Shrink, Controlled Expansion
Expands slightly as it sets to ensure tight contact with bolts, anchors, and surrounding concrete.
Fast Setting Performance
Begins setting in approximately 20–30 minutes, allowing efficient jobsite turnaround.
Easy On-Site Mixing
Single-component system requiring only clean water for activation—no additives or special equipment needed.
Corrosion Resistant
Non-metallic and non-alkaline properties help reduce the risk of rusting embedded steel hardware.
Versatile Application Use
Suitable for anchoring, patching, void filling, and concrete crack repair across multiple construction environments.
Common Applications
Structural Anchoring
Used for securing:
- Anchor bolts
- Railings and guardrails
- Sign posts
- Machinery bases
- Banisters and handrails
Concrete Repair
Ideal for filling:
- Cracks in concrete
- Voids and cavities
- Damaged substrate areas
Industrial & Commercial Installations
Commonly used in:
- Manufacturing facilities
- Parking structures
- Infrastructure projects
- General construction anchoring work
Recommended Use Areas
Por-Rok is suitable for:
- Concrete floors
- Walls and vertical structures
- Structural columns
- Exterior concrete installations
- Interior anchoring applications
- Industrial equipment foundations
Application Instructions
Surface Preparation
- Concrete must be fully cured (minimum 28 days)
- Clean all holes and surfaces thoroughly
- Remove dust, debris, and loose particles
- Pre-wet surfaces to a saturated surface-dry (SSD) condition
Mixing Instructions
- Add clean potable water to dry powder
- Mix to a smooth, flowable consistency
- Adjust water slightly depending on desired stiffness
- Avoid overwatering to maintain strength
Placement
- Pour mixed material into prepared hole or void
- Insert anchor bolt or hardware immediately
- Ensure full encapsulation around embedded object
- Allow material to set undisturbed
Finishing Notes
- Shape surface as needed during early set
- Prevent standing water around finished anchoring point
- Allow proper curing time before loading
Coverage & Yield
- 50 lb unit yields approximately 0.5 cubic feet
- Approximate density: 110 lbs per cubic foot
Performance Characteristics
Compressive Strength
Develops very high early and long-term strength exceeding conventional concrete performance.
Expansion Control
Minimal controlled expansion (~0.15%) ensures tight anchoring bond.
Temperature Range
Typical application range: 35°F to 95°F
Set Time
Initial set: ~20–30 minutes (depending on conditions)
Packaging
- 50 lb pails/bags
- Bulk pallet quantities available
Shelf Life & Storage
Shelf Life
- 12 months in properly stored, unopened packaging
Storage Conditions
- Store in a dry, cool environment
- Keep containers sealed
- Avoid moisture exposure prior to use
- Rotate stock regularly
Frequently Asked Questions
What is Por-Rok used for?
It is used to anchor bolts, rods, railings, machinery, and structural components into concrete and to repair cracks or voids.
How fast does Por-Rok set?
It typically begins setting in 20–30 minutes depending on temperature and mix conditions.
Does Por-Rok shrink?
