ETI injection epoxies are two-component, high-solids formulations for the injection into cracks in concrete. Dispensed through a static mixing nozzle using either a manual, battery-powered or a pneumatic dispensing tool, these epoxies provide a waterproof, high strength (structural) repair.

Key Features

  • Bonds chemically to concrete, providing load-bearing applications (meets the requirements of ASTM C 881 for structural repair epoxy)
  • Formulated for maximum penetration under pressure (all viscosities)
  • Seals out moisture, protecting rebar in the concrete from corrosion and flooring from moisture damage
  • Reliable mixing and ratio control when used with the Simpson Strong-Tie® Optimix® static mixing nozzle (included with cartridge)
  • Suitable for pressure injection
  • Non-shrink material resists oils, salts and mild chemicals
  • Final product color: ETI-SLV — dark purple / black; ETI-LV — amber; ETI-GV — gray

ETI-SLV Super-Low-Viscosity Epoxy

  • Super-low viscosity (350 cP) repairs hairline cracks (0.002") and cracks up to 1/4" in width
  • Penetrates smallest cracks
  • Meets or exceeds AASHTO M-235 and ASTM C881 Type I and IV, Grade 1, Class B and C

ETI-LV Low-Viscosity Epoxy

  • Repairs fine to medium cracks 1/64" to 1/4" in width
  • Offers low surface tension to effectively penetrate narrow cracks
  • Approved under NSF/ANSI standard 61
  • Meets or exceeds AASHTO M-235 and ASTM C881 Type I and IV, Grade 1, Class C

ETI-GV Gel-Viscosity Epoxy

  • Gel-viscosity (non-sag) epoxy repairs medium cracks 3/32" – 1/4" in width
  • Decreases in viscosity under pressure, increasing flow
  • Suitable for use as pick-proof sealant around doors, windows and fixtures
  • Meets or exceeds AASHTO M-235 and ASTM C881 Type I and IV, Grade 3, Class C

ETISLV ETI-SLV Super-Low-Viscosity Cartridge System, 16.5 oz. 1 10 EDT22S dispensing tool / EMNO22 mixing nozzle (included)

Storage Conditions

  • For best results, store between 45°F and 95°F

Shelf Life

  • 24 months from date of manufacture in unopened cartridge


  • Suitable for repairing non-moving cracks in concrete walls, floors, slabs, columns and beams.
  • ETI can be used to inject cracks in damp or wet conditions (non-seeping or non-leaking conditions only) with excellent results.
  • Apply to concrete 40°F or above. For best results, warm material to 60°F or above prior to application.
  • Mixed material in nozzle and injection fitting hardens in 15 minutes (ETI-SLV), and in 60 minutes (ETI-LV, ETI-GV) at temperatures of 40°F or above.
  • Use only appropriate Simpson Strong-Tie mixing nozzles in accordance with Simpson Strong-Tie instructions. Modification or improper use of mixing nozzle may impair epoxy performance.
  • ETISLV, ETILV22 and ETIGV22: EDT22S tool must be configured for 2:1 cartridge ratio.

Clean Up

Removal of cured adhesive — Chip or grind off surface. Uncured Adhesive — Wipe up with cotton cloths. If desired, scrub area with abrasive, water-based cleaner and flush with water. If approved, solvents such as ketones (MEK, acetone, etc.), lacquer thinner, or adhesive remover can be used. DO NOT USE SOLVENTS TO CLEAN ADHESIVE FROM SKIN. Take appropriate precautions when handling flammable solvents. Solvents may damage surface to which they are applied.
