General Information
Overview
EN 14068:2003 - Products and systems for the protection and repair of concrete structures - Test methods - Determination of watertightness of injected cracks without movement in concrete (CEN) specifies a laboratory test method to assess the watertightness of injected cracks of defined width in concrete. The method evaluates how well injection materials (resins, sealants, grouts) restore impermeability when injected into static cracks, using controlled specimen preparation, injection, curing and a hydraulic pressure test.
Key topics and requirements
- Test principle: Inject a product into a crack of defined width and, after curing, apply increasing hydraulic pressure to one face to check leakage (watertightness).
- Specimen geometry: Cylindrical test specimens 150 ± 2 mm diameter × 100 ± 2 mm height, saw-cut and split to create a crack.
- Crack width control: Crack opening set to (1 ± 0.2) mm using inert spacers; crack faces sealed at edges to restrict flow paths.
- Number of specimens: Tests carried out on three specimens per product/condition.
- Conditioning and environment: Standard lab climate (21 ± 2) °C and 60 ± 10 % RH for conditioning, injection, curing and testing; assembly stored 48 ± 4 h before injection.
- Crack moisture states: Supports testing under dry, damp, wet or water-filled crack conditions (including injection against a head of water) as specified by the injection product manufacturer.
- Injection and curing: Injection according to manufacturer instructions; specimen curing for 7 days at standard climatic conditions.
- Apparatus: Simple pressurised water chamber to apply hydraulic pressure while allowing observation of opposite face; sealing elements (elastomeric bitumen), spacers and injection equipment specified.
- Result expression: Watertightness judged by pressure steps and leakage detection (procedure and result reporting described in the standard).
Applications and users
EN 14068:2003 is practical for:
- Manufacturers of injection resins, epoxies, acrylates and polyurethane systems - for product development and performance claims.
- Independent test laboratories and quality-control facilities - to verify watertightness under standard conditions.
- Contractors and specifiers in concrete repair and waterproofing - to select suitable injection products for static crack remediation.
- Certification bodies and compliance teams - as part of conformity assessment with the EN 1504 series (concrete repair standards).
