Features

  • High compatibility: Designed for common 3000psi (or higher) bagged concrete with gravel, sand, and Portland cement
  • Boosts flexibility: Makes standard concrete over 700% more flexible for stronger paver edge restraint
  • Water stop technology: Waterproofs the entire concrete volume and helps seal non‑moving cracks up to 0.016in
  • Shrink control: Greatly reduces cracking from drying and autogenous shrinkage, extending the life cycle
  • Void reduction: Increases compressive and flexural strength while lowering permeability for longer‑lasting concrete
  • Fiber reinforced: Macro synthetic fibers reduce shrinkage and settlement cracking, and improve impact resistance and durability
  • Generous coverage: Each mixed bag yields about 18 to 26 feet of paver edging, depending on application
  • On‑site mixing: Added to the dry concrete on-site before water is mixed in for simple use
  • Made in the USA: Domestic manufacturing for consistent quality
