Concrete Claw

Concrete Claw

Concrete Claw – Concrete Structure Repair is a system is designed to repair damaged cracks or separations in concrete surfaces with a much stronger, higher strength, American steel claw which holds the structure in place, while preventing further separation.  Concrete Claws imbedded in concrete structures will enhance the structural strength of the surface while holding it together from within.


The unique and optimum advantage for the Concrete Claw is that it will lock-in multi-directional movements that are inherent with many phases of expansion and contraction of the surface impacted by shifting geotextiles underneath.  It is important to repair damaged cracks or separations in concrete at it’s break point.  Concrete Claw – Concrete Structure Repair will protect the surface from vertical and horizontal stress quickly, permanently and cost effectively.

Concrete Claw

Concrete Claw Benefits

  • Replaces the Structural Strength of Concrete at the Break Point
  • Withstands Multi-directional Stress from Expansion/Contraction
  • Withstands 114,000 pounds of pressure
  • Permanent Repair for Separations in All Concrete Surfaces
  • Much Easier and Cost Effective than Replacing the Whole Surface Area

Concrete Claw Recommended Uses

  • Patios
  • Pool Decks and Pool Basins
  • Concrete Claw 2Foundations
  • Garage Slabs
  • Retaining Walls
  • Walkways and Stairs

Concrete Claw Available Sizes 

  • 12”, 18” and 24” Lengths individually and in kits that include the epoxy anchors

Concrete Claw Installation Schedule According to Surface Thickness

  • 4” thick – Every 16” on Center – With one at 6” from edge of concrete
  • 5” thick – Every 14” on Center – With one at 6” from edge of concrete
  • 6” thick – Every 12” on Center – Alternate 12” and 18” Claws at 12” on Center

Concrete Claw Installation Instruction

Concrete Claw 3

  • Set Claws in place according to required measurements
  • Line up Claws on Center and drill 3” deep X 3/4” diameter holes for the vertical ends of the Claw
  • Cut a 1” deep channel across the separation where the Claw can fit within the surface
  • Fill the holes and channel with epoxy anchor 2000PC and insert the Claw in place
  • When the Epoxy Anchor is cured, the crack can be filled with epoxy, or Quick Crete would be just as good for this step and less expensive.
  • Apply the top coat if needed.

* See the product data on PANSEAL Cartridges Data Sheet 2000PC for cure times and further information on the Epoxy Anchor

 High Strength Anchor for the Concrete Claw – 2000PC


PANSEAL 2000PC is a unique, multi-component epoxy system that was originally formulated to permanently seal leaks in HVAC drain pans and coat and protect metals from corrosion.  PANSEAL also serves as an excellent, high-strength anchor in concrete for the Concrete Claw.

 Product Features & Benefits

  • Excellent adhesion strength – 2,750 psi (pull-off adhesion test ASTM D 4541)  PANSEAL Cartridges
  • Locks Concrete Claws in Place Preventing Movement
  • Minimal system down time
  • Easy to Apply with a Caulk Gun – Sets up Underwater
  • 100% solids and entirely free of solvents and VOCs.
  • Very Minimal Odor
  • Bonds chemically and mechanically to the substrate

 Recommended Uses

  • Adhesive Anchor for Concrete Claws
  • Cooling Tower Repair
  • Condenser Pans
  • Tank Linings


Make sure to remove dust an debris within the holes for the Concrete Claw.


PANSEAL Cartridges are supplied in a dual chamber cartridge with a self-mixing nozzle attachment.

  1. Remove the nut and then then the stopper.
  2. Attach the mixing nozzle and secure with the nut.
  3. Apply with a caulk gun into the drilled hole to support the Concrete Claws.
  4. Continue to fill all holes, as material left too long in the nozzle will harden within.

*   As pressure is applied with the caulk gun, the material mixes itself as it spirals through the mixing nozzle.  

Cure Schedule

  • 10°C (50°F)
  • 25°C (77°F)
  • 60°C (140°F)
