This part of this document specifies requirements and conformity criteria for the identification, performance (including durability aspects) and safety of injection products for the repair and protection of concrete structures, used for:
- force transmitting filling of cracks, voids and interstices in concrete (category F, see 3.1);
- ductile filling of cracks, voids and interstices in concrete (category D, see 3.1);
- swelling fitted filling of cracks, voids and interstices in concrete (category S, see 3.1).
The performance requirements in this part of this document may not be applicable to highly specialised applications in extreme environmental conditions, e.g. cryogenic use, nor do they cover specialised circumstances such as accidental impact, e.g. due to traffic or ice, or earthquake loading, where specific performance requirements will apply.
This part of this document does not cover:
- the treatment of cracks by widening them and sealing them with an elastomeric sealing compound;
- external filling of cavities, that is the placement of product outside the structure (generally within the surrounding foundation soils, or at the interface between the structure and the soil). This is covered by EN 12715, under contact grouting [1];
- preliminary injection works, if necessary, to temporarily stop water passage during waterproofing injection.

EN 1504-5:2004 (E) 5 Introduction Concrete injection is used as a method for the following principles defined in ENV 1504-9: principle 1 [IP]: Protection against ingress and waterproofing; Filling cracks (method 1.4). principle 4 [SS]: Structural strengthening; Injecting cracks, voids or interstices (method 4.5). Filling cracks, voids or interstices (method 4.6). Injection is used to avoid the harmful consequences of voids and cracks in concrete: to achieve impermeability and hence watertightness; to avoid penetration of aggressive agents that might induce corrosion of steel reinforcement; to strengthen the structure by strengthening the concrete.
EN 1504-5:2004 (E) 6 1 Scope This part of this document specifies requirements and conformity criteria for the identification, performance (including durability aspects) and safety of injection products for the repair and protection of concrete structures, used for: force transmitting filling of cracks, voids and interstices in concrete (category F, see 3.1); ductile filling of cracks, voids and interstices in concrete (category D, see 3.1); swelling fitted filling of cracks, voids and interstices in concrete (category S, see 3.1). The performance requirements in this part of this document may not be applicable to highly specialised applications in extreme environmental conditions, e.g. cryogenic use, nor do they cover specialised circumstances such as accidental impact, e.g. due to traffic or ice, or earthquake loading, where specific performance requirements will apply. This part of this document does not cover: the treatment of cracks by widening them and sealing them with an elastomeric sealing compound; external filling of cavities, that is the placement of product outside the structure (generally within the surrounding foundation soils, or at the interface between the structure and the soil). This is covered by EN 12715, under contact grouting [1]; preliminary injection works, if necessary, to temporarily stop water passage during waterproofing injection. 2 Normative references The following referenced documents are indispensable for the application of this document.

Unless otherwise stated, injection products are intended for filling of cracks, voids and interstices, so that in the following, only the wording injection products for filling of cracks is used 3.1.2 injection products for ductile filling of cracks, voids and interstices in concrete (D) flexible products which are able to accommodate subsequent movement 3.1.3 injection products for swelling fitted filling of cracks, voids and interstices in concrete (S) products which are able, in the reacted state, to swell repeatedly by water adsorption, where the water molecules are bonded to the molecules of the injection product NOTE This category of products, referred to as gels, are only used for waterproofing purposes for cracks and voids in damp, wet and water - flow conditions.
3.2 injection product formulated with reactive polymer binder (P) product where the hardening is related to the curing of a reactive polymer binder. The reactive part of a polymer binder involved in the hardening of the binder is the functional group 3.3 injection product formulated with hydraulic binder (H) product where the hardening is related to the hydration reaction of an hydraulic binder
EN 1504-5:2004 (E) 9 3.4 pot life for injection products period of time taken by the freshly mixed product to: increase in temperature by 15 °C, for injection products formulated with reactive polymer binder (or the maximum temperature increase if less than 15 °C); or to reach a recorded lowering of the filtration stability for injection products formulated with hydraulic binder NOTE Pot life is an identification test carried out under standard laboratory conditions. 3.5 workable time for injection products period of time the mixed injection product remains workable in the batch quantities used and at the limit of conditions that the product is fit for the purpose of use. The workable life is assessed by the determination of the pot life, and is equivalent to 70 % of the pot life, if no other recommendations are given by the manufacturer NOTE The workable life depends on temperature, humidity, volume of mixed product (A+B), reactivity of the product, technology of injection. Reactivity of the product and volume of mixed product should be chosen according to those various parameters and to the anticipated time necessary to inject the concrete structure. 3.6 crack width width of the crack measured on the surface of the concrete 3.7 injectability ability of an injection product to penetrate in a crack. The injectability is given by the minimum crack width in millimetres into which the product is injectable. Following crack widths are considered: 0,1mm | 0,2 mm | 0,3 mm | 0,5 mm | 0,8 mm NOTE The injectability is declared by the manufacturer, and tested with the injectability test(s) (see Clause 4). 3.8 moisture state of the crack water content in the crack or flowing from the crack The following conditions are considered: dry | damp | wet | water flowing. Dry: no water in the crack or on the crack flanks; migration of water in the crack is excluded during injection and hardening of injection product. NOTE A dry crack is indicated if the colour of the crack and dry surface concrete is the same. Damp: no water in the crack, water on the crack flanks, however without a water layer on the surface of the flanks. NOTE A difference of colour between the crack surface and the dry surface concrete gives evidence of a damp crack. Wet: standing water in the crack. NOTE The presence of water drops on the crack surface is characteristic of a wet crack. Water flowing:
flowing water through the crack. NOTE The manufacturer should indicate the moisture state or states with which the product is compatible, based on the results of the injectability and other relevant performance tests specified in Clause 4.
EN 1504-5:2004 (E) 10 3.9 crack movement change of crack width as a function of time and induced by: mechanical influences (e.g. by traffic); by physical influences, which can be daily (for example due to exposure to the sun) or seasonally. NOTE 1 Traffic induced crack movements of 10 µm to15 µm during cure do not influence the adhesion of injection products formulated with reactive polymer binder. NOTE 2 Gels should not be used for cracks submitted to daily movements unless also injected in excess outside the structure. NOTE 3 Injection products formulated with hydraulic binder should not be used for the injection of cracks submitted to high frequency changes during hardening. The products should normally not be used for injection of cracks submitted to daily changes during hardening, unless it can be proved that the adhesion on concrete will be higher than 2 N/mm2 within 10 h at the minimum use temperature. 4 Performance characteristics in relation to the general principles of protection and repair Tables 1.a, 1.b and 1.c list the performance characteristics of concrete injection products which are required for "all intended uses" or "for certain intended uses" according to the "principles" and "methods" defined in ENV 1504-9. Performance characteristics which are required for "all intended uses" are marked with v. All other performance characteristics which are marked with ‘ may be required for "certain intended uses". The performance characteristics of products are classified as follows: basic characteristics, related to adhesion, shrinkage, compatibility with steel and concrete, glass transition temperature, watertightness essential for the intended use; workability characteristics, related to the work conditions which the product can be used for (width, moisture state of the crack); these characteristics are declared by the manufacturer, and tested accordingly; reactivity characteristics, related to the workable life and the development of strength; durability, related to the long term behaviour of the hardened product under climatic conditions. NOTE Workability and reactivity characteristics are product characteristics for the designer and contractor. The performance characteristics of injection products used in relation to Principle 1 [IP]: Protection against ingress and waterproofing - Filling cracks (method 1.4 as described in ENV 1504-9:1997) are listed in the following tables: Table 1.a: "Injection products for force transmitting filling of cracks – performance characteristics" when category F products are used for these purpose; Table 1.b: "Injection products for ductile filling of cracks - performance characteristics" when category D products are used for these purpose; Table 1.c: "Injection products for swelling fitted filling of cracks - performance characteristics" when category S products are used for these purpose. Only products formulated with reactive polymer binder can be considered for category D and category S injection. The performance characteristics of injection products used in relation to Principle 4 [SS]: Structural Strengthening – Injecting cracks, voids and interstices (method 4.5 as described in ENV 1504-9:1997) and Filling cracks, voids or interstices (method 4.6) are listed in Table 1.a: "Injection products for force transmitting filling of cracks - performance characteristics".
EN 1504-5:2004 (E) 11 Corrosion behaviour of injection products formulated with hydraulic binder is assessed by measuring chloride content. Injection products formulated with reactive polymer binder for category F and category D injection are deemed to have no corrosive effect on reinforcement. The certain intended uses are subject to specific conditions on the works: glass transition temperature shall be considered if the temperature of the hardened product in the crack can be: higher than 21 °C (temperature conditions by measuring adhesion strengths) for category S products formulated with reactive polymer binder; lower than 3 °C (temperature conditions by measuring elongation ability) for category D products; chloride content and corrosion behaviour shall be considered by injection of reinforced concrete; watertightness shall be considered for waterproofing injection; expansion ratio and evolution for category D products gives knowledge on the behaviour of the product by injection of wet or water flowing cracks. The injectability test (into dry or non dry medium) is performed at the minimum crack width declared by the manufacturer and the least favourable moisture state of the crack declared by the manufacturer for the tested product. Performance requirements are given in 5.2. The properties of the bonding may be adversely affected by fire and therefore appropriate protection measures will need to be taken where fire is anticipated.
