Cracks - Sikadur® Crack Repair Kit
Concrete crack repair system
Sikadur® Crack Repair Kit is a two multicomponent, low viscosity, fast curing, epoxy sealing system for the repair of cracks that occur in solid concrete and solid masonry substrates.
- Convenient easy to use, single tube cartridges that fit standard caulk guns
- Easily mixed when dispensed through flow restrictor (needed for the Sikadur® Injection Resin component only) and static mixers
- Up to three times stronger than existing concrete when cured
- Penetrating and bonding of cracks in concrete when injected (reference: ACI Rap Bulletin 1)
- Excellent for notch and fill, isolated crack repair by gravity feed method using the Sikadur® Injection Resin component (reference: ACI Rap Bulletin 2)
- Early strength developing adhesives for “can’t dry” surfaces (i.e. tolerates dampness with no standing water present)
- Excellent chemical resistance; prevents chloride ion intrusion and further water absorption when cured
- Prolongs life of cracked concrete elements
Usage
Sikadur® Crack Repair Kit may only be used by experienced professionals.
- For manual, low pressure injection of horizontal flat and/or vertical static cracksin solid concrete, solid masonry, wood, etc.
- For gravity feed of static cracks (using the Sikadur® Injection Resin component only) in horizontal flat concrete, solid masonry, wood, etc.
- For the sealing of minor, static surface cracks, voids or gaps (using the Sikadur® Capseal component only) in horizontal flat, vertical and/or overhead surfaces in concrete, masonry, wood, etc.
- As a flowable, liquid epoxy grout to fill thin voids below baseplates

Consumption
CoverageSikadur® 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.
Application Steps
APPLICATION INSTRUCTIONSGeneral:
- 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.
SUBSTRATE QUALITY- 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.
