IN COMPLIANCE WITH EUROPEAN STANDARD CONCRETE INJECTION Two-component epoxy resin, with very low viscosity for injection in microcracks, also on wet surfaces • onding steel plates to concrete (béton plaqué) B by low pressure injection. TECHNICAL CHARACTERISTICS Epojet LV is a two-component epoxy adhesive. The pre-measured components (component A = resin and component B = hardener) must be mixed together before being used. Some application examples • tructural repair of beams, pillars and cracked S floors by low pressure injection. Once mixed, Epojet LV becomes a very fluid liquid that can easily penetrate even in microcracks. WHERE TO USE • onolithic sealing of cracks. M • einforcement of beams and floors by injection R with the béton plaqué method, when the plates to be bonded are fitted with lateral flaps and it is therefore impossible to apply Adesilex PG1 or Adesilex PG2. • epair of architectural concrete, wall coverings R and architectural elements that are crumbly. Epojet LV polymerizes without any significant amount of shrinkage, also on wet surfaces and once hardened is waterproof and resists chemical agents present in the atmosphere. Epojet LV has very good insulating properties and high mechanical strength. • ealing of cracks in cementitious screeds. S Epojet LV meets the requirements defined by EN 1504-9 (“Products and systems for the protection and repair of concrete structures definitions, requirements, quality control and evaluation of conformity - General principles for the use of products and systems”) and the minimum requirements claimed by EN 1504-5 (“Concrete injection”). • estoration, by injection, of concrete structures R damaged by earthquakes, settlements or impacts. RECOMMENDATIONS • o not use Epojet LV at temperatures below D +10°C. • tructural consolidation and restoration S of civil and industrial road constructions and underground works that

• Do not apply Epojet LV on dusty, crumbly or weak substrates. • Do not use Epojet LV for sealing expansion joints. APPLICATION PROCEDURE Preparation of the substrate Before injecting Epojet LV, the concrete surface must be perfectly sound and clean. Positioning the steel reinforcement and injection Clean all traces of rust or grease from the reinforcements by sandblasting to bright metal (SA 2½). Once these preparation procedures have been completed, securely fix the steel plates to the concrete with expanding bolts. Position the injectors in the space between the structure and the plate...
