Best for

  • Heavy structural post-installed anchors
  • Seismic retrofit
  • Bridge and infrastructure
  • Rebar splicing and doweling
  • Industrial equipment bases

Not suitable for

  • Temperatures below 40°F without cold-weather system
  • Sustained high temperature (>110°F) without HTE-rated epoxy
  • Underwater without underwater epoxy

Installation tips

  • 1.3-step hole cleaning is critical: blow, brush, blow — skip this and capacity drops 30-50%
  • 2.Use a calibrated adhesive dispenser — mix ratio must be correct or epoxy won't cure properly
  • 3.Full cure at 70°F is typically 24 hours — check TDS for your specific product
  • 4.Engineer specification required for all structural applications
  • 5.Diamond core drill produces better hole geometry than hammer drilling for critical applications
