Sikadur® Crack Repair Kit

Sikadur® Injection Resin conforms to the current requirements of ASTM C881 / M 235, Types I and II, Grade 1, Class C.*
* except for Gel Time and Slant Shear (Bond) Strength

18 months from date of production if stored properly in original, unopened and undamaged, sealed packaging.

Store in cool, dry, well ventilated conditions, out of direct sunlight at 40 - 75°F (4 - 24 °C).

Sikadur® Injection Resin

Product cured and tested at temperatures indicated in table. Test specimen size: 1/2" × 1/2" × 1"

Condition cartridges to 65 - 75 °F (18 - 24 °C) before set-up and mixing / dispensing.

40 °F (4 °C) minimum / 95 °F (35 °C) maximum

Beware of surface condensation! To avoid dew point conditions during application, substrate temperature must be at least 5 °F (3 °C) above measured dew point temperature.

40 °F (4 °C) minimum / 95 °F (35 °C) maximum

Sikadur® Capseal

Sikadur® Injection Resin

Sikadur® Capseal: Placed at 1 inch (25 mm) wide x 1/8 inch (3 mm) thick yields approximately 10 linear feet (3 linear meters) per cartridge*

Sikadur® Injection Resin: Injected or gravity fed into a 1/8 inch (3 mm) wide (3 mm) wide x 1 inch (25 mm) deep crack yields approximately 10 linear feet (3 linear meters) per cartridge*

(1) Sikadur® Crack Repair Kit kit typically repairs approximately 15 to 20 linear feet (4.5 to 6.0 linear meters) of cracked concrete.*

* Estimates based on theoretical calculation. Actual field coverage rates may vary based on actual concrete conditions.

General:

• Surfaces must be clean, sound, dust-free and as dry as possible. Surfaces may be damp, but freeof standing water and frost. 
• Remove dust, laitance, grease, oil, tar, curing compounds, impregnations, waxes, loosely adhering bond inhibiting foreign particles, disintegrated materials and all other contaminants. 
• If a wet method of substrate preparation is considered, allow surfaces to thoroughly dry for a minimum 24 to 48 hours. 
• Mask off and protect any adjacent surfaces that should not receive contact with Sikadur® Capseal or Sikadur® Injection Resin.

Solid Concrete, Solid Masonry:

Pressure Injection of static (i.e. nonmoving) cracks

• Cracked substrate must be solid and not allow Sikadur® Injection Resin to pass through its thicknessand/or escape when injected. 
• Mechanically prepare (i.e. roughen; profile to a minimum ICRI CSP-2 to CSP-3) surfaces using a wire brush, abrasive grinder or similar. 
• Remove dust, standing water and obstructions visible within the crack void using brushes, a wet/dry vacuum and/or oil free compressed air. 
• After injection ports are mounted and cap seal gel adhesive is sufficiently cured, use oil free compressed air to force any standing water that may be present out of the crack void. Start at injection port locatedat the highest elevation to force standing water downward and out of lower injection ports.

Gravity Feed of static (i.e. nonmoving) cracks

• Cracked substrate must be solid and not allow Sikadur® Injection Resin to pass through its thicknessand/or escape when gravity fed. 
• Notch cracks open to approximately 1/8 inch (3 mm) wide by 1/8 inch (3 mm) deep minimum. Do not exceed 1/4 inch (6 mm) wide by 1/4 inch (6 mm) deep maximum. 
• Remove dust, standing water and obstructions visible within the crack void using brushes,a wet/dry vacuum and/or oil free compressed air.

• Minimum age of concrete must be 21–28 days, depending on curing and drying conditions.
• Substrate surfaces along the line of the crack required for the Sikadur® Capseal, must be sound, clean and dry. Free from standing water, ice, dirt, oil, grease, coatings, laitance, efflorescence, old surface treatments, all loose particles and any other surface contaminants that could affect adhesion of the injection ports.
• Cracks must be clean. Horizontal cracks, which are filled by the 'gravity feed' technique, should be v-notched along the entire crack length with grinding equipment.

Preparing the Sikadur® Capseal Cartridge

Note: When the work is interrupted, the square mixing nozzle can remain on the cartridge after the gun pressure has been released. If the resin has hardened in the nozzle when work is resumed, a new square mixing nozzle must be attached.
