Injection products can be classified in three categories, according to the intended use. 3.1.1 injection product for force transmitting filling of cracks, voids and interstices in concrete
(F) product able to bond to the concrete surface and transmit forces across it Note 1 to entry:
Products for injection for force transmitting filling of cracks, voids and interstices can also be used for saturation without receiving a force transmitting bond. Note 2 to entry:
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 product for ductile filling of cracks, voids and interstices in concrete (D) flexible product which is able to accommodate subsequent movement 3.1.3 injection product for swelling fitted filling of cracks, voids and interstices in concrete (S) product which is 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 1 to entry:
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 3.4 pot life for injection products
period of time taken by the freshly mixed product to:
 to reach a viscosity of 1 000 mPa·s  to reach a recorded lowering of the filtration stability for injection products formulated with hydraulic binder Note 1 to entry:
Pot life is an identification test carried out under standard laboratory conditions. Note 2 to entry:
Test sample: 1 000 ml. 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
Note 1 to entry:
The workable time is given by the manufacturer. Note 2 to entry:
The workable time 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 are best 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 not mechanical treated surface of the concrete 3.7 injectability ability of an injection product to penetrate in a crack, which is given by the minimum crack width into which the product is injectable Note 1 to entry:
Following crack widths are considered: 0,1mm | 0,2 mm | 0,3 mm | 0,5 mm | 0,8 mm. Note 2 to entry:
Crack width is expressed in millimetres. Note 3 to entry:
The injectability is declared by the manufacturer, and tested with the injectability test(s) (see Clause 4). 3.8 moisture state of the crack, voids or interstices water content in the crack or flowing from the crack Note 1 to entry:
The following conditions are considered: dry, damp, wet, flowing water. 3.8.1
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 1 to entry:
A dry crack is indicated if the colour of the crack and dry surface concrete is the same. 3.8.2
damp no water in the crack, water on the crack flanks, however without a water layer on the surface of the flanks Note 1 to entry:
A difference of colour between the crack surface and the dry surface concrete gives evidence of a damp crack. SIST EN 1504-5:2013

The presence of water drops on the crack surface is characteristic of a wet crack. 3.8.4
flowing water water that flows through the crack, voids or interstices Note 1 to entry:
The manufacturer will 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. 3.9 crack movement change of crack width as a function of time and actions on structures Note 1 to entry: Actions on structures are induced by:  mechanical influences (e.g. by traffic);  physical influences, which can be daily (for example due to exposure to the sun, change of temperature) or seasonally. Note 2 to entry:
Traffic induced crack movements of 10 µm to 15 µm during cure do not influence the adhesion of injection products formulated with reactive polymer binder. Note 3 to entry:
Gels will not be used for cracks submitted to daily movements unless also injected in excess outside the structure. Note 4 to entry:
Injection products formulated with hydraulic binder will not be used for the injection of cracks submitted to high frequency changes during hardening. These products are normally not 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, 2 and 3 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
EN 1504-9. Performance characteristics which are required for “all intended uses” are marked with 9. All other performance characteristics which are marked with : may be required for “certain intended uses”. See Annex B for special applications. The performance characteristics of products are classified as follows:  basic characteristics, compressive strength, strength related to adhesion, volume change (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 time 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. SIST EN 1504-5:2013
