Cracks - Sikadur® Injection Gel

High-modulus, high-strength, structural, non-abrasive, smooth epoxy paste adhesive

Sikadur® Injection Gel, Standard Set is a 2-component, 100 % solids, moisture-tolerant, high-modulus, highstrength, structural epoxy. When mixed it gives a smooth, non-abrasive, paste adhesive. It conforms to the current ASTM C-881, Types I and IV, Grade-3, Class-C and AASHTO M-235 specifications.

  • Unique, non-abrasive texture permits application with automated pressure-injection equipment.
  • Tolerant of moisture before, during, and after cure.
  • High-modulus, high-strength, structural-paste adhesive.
  • Excellent adhesion to masonry, concrete, wood, steel and most structural materials.
  • Paste consistency ideal for vertical and overhead grouting of cracks.
  • Convenient easy mix ratio A:B = 1:1 by volume.
  • Excellent lubricity for deep penetration.
  • Sikadur Injection Gel fast set is approved for short term loads only. Consult a design professional prior to use.

Usage

  • Structural crack repairs not exceeding 1/4 in. (6 mm) width.
  • Mechanical grouting. . . bolts, dowels, pins, machine and ‘robotic’ base plates, bearing pads, etc.
  • Waterproofing tunnels, cable vaults, tanks, basements, etc.
  • Re-anchoring of veneer masonry. Consult a design professional prior to use.
  • Wood-truss repairs.
  • Preventive maintenance - grout large cracks on new orexisting structures to seal off reinforcing steel from the elements of corrosion.
  • Anchor grouting . . . bolts, dowels, pins and special fasteners. Consult a design professional prior to use.
  • As a pick-proof sealant around windows, doors, lock-ups, etc. inside correctional facilities.

Application Steps

SUBSTRATE PREPARATION

Surface must be clean and sound. It may be dry or damp, but free of standing water. Remove dust, laitance, grease, curing compounds, impregnations, waxes and any other contaminants.
Preparation Work: Concrete - Should be cleaned and prepared to achieve a laitance and contaminant free, open textured surface by blastcleaning or equivalent mechanical means.
Steel - Should be cleaned and prepared thoroughly by blastcleaning.

MIXING

Sikadur® Injection Gel, Standard Set is specially designed and formulated to be mixed and applied with automated pressure-injection equipment. Follow the recommendations and directions supplied by the equipment manufacturer.
Pre-mix each component. Proportion equal parts by volume of Component ‘B’ and Component ‘A’ into a clean pail. Mix thoroughly for 3 minutes with Sika paddle on low-speed (400-600 rpm) drill until uniform in color. Mix only that quantity that can be applied within its pot life.
