Features & Benefits

• Structural repairs of beams, pillars and fissured floors by low pressure injection
• Reinforcement of beams and floors by using injection and béton plaqué, the plated concrete technique, when the plates to be bonded are fitted with lateral flaps and it is therefore impossible to apply Adesilex PG1 directly
• Restoring and waterproofing cracks in reservoirs, tanks and canals
• Restoring, by injection, various elements of façades, cladding and architectural elements that are loose
• Protective injections of post-compression cable ducts
• Structural consolidation and restoration of civil and industrial road constructions which show signs of cracking
• Sealing of fissures in cementitious screeds
• Consolidation and restoration, by injection, of concrete structures damaged by earthquakes, settlement or impact
• Anchoring metallic structural work and steel reinforcement

Technical Characteristics

Epojet is a two-component solvent-free epoxy adhesive. The pre-measured components (component A = resin and component B = hardener) must be mixed together before being used

Once mixed, Epojet becomes a liquid with low viscosity very suitable for injection

Epojet polymerizes without shrinkage and once hardened is waterproof

Epojet has very good insulating properties and high mechanical strength; furthermore it adheres perfectly to concrete and steel

Epojet 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”), the minimum requirements claimed by EN 1504-5 (“Concrete injection”) and the minimum requirements for EN 1504-6 (“Anchoring steel reinforcement”)

Recommendations

• Do not use Epojet at temperatures below 5°C
• Do not apply Epojet to wet surfaces
• Do not apply Epojet on dusty, friable or weak substrates
• Do not use Epojet for sealing expansion joints

Application

Prepare the substrate

Before injecting Epojet, the concrete substrate must be perfectly sound and clean. Remove all crumbly and loose parts, dust, cement laitance and paint by sanding or brushing. Concrete soaked with oil or grease must be completely demolished.

Placing the steel reinforcement and injection

Remove all traces of rust or grease by sandblasting down to bright metal (SA 2½) or, if necessary, with emery paper and de-grease with solvents.

Once these preparatory procedures have been completed, fix the steel plates to the concrete with expanding bolts and then seal the injectors with Adesilex PG1.

Sealing cracks by injection

Make a series of holes of 8-9 mm in diameter along the sides of the cracks and orient the injectors to intercept the cracks.

Blow out the cavities with compressed air to remove all the dust formed during the drilling. Insert the appropriate injection tubes into the holes and seal with Adesilex PG1.

If it is not possible to drill holes because the cracks are so small and widespread throughout the concrete, use injectors with a flat end plate and fasten them to the concrete over the cracks with expansion plugs, or with Adesilex PG1. Wait until the Adesilex PG1 has set (at least 12 hours) and then inject compressed air to make sure the system is completely free.

Preparing the product

First the two components of Epojet must be mixed together. Pour component B into component A and manually mix with a trowel (for small amounts), or with a low speed heavy duty drill (for large quantities) avoiding the formation of air bubbles and until the mix is perfectly homogeneous. Do not use partial quantities of the parts to avoid measuring errors that could lead to the incomplete hardening of Epojet. If the packs need to be used partially, use an electronic precision scale.

Applying the product

Begin immediately from the lowest tube and start injecting Epojet until the resin overflows out of the next tube. Close the tube used for injection and inject Epojet in the next one positioned just above until the fissure is completely sealed.

Horizontal fissures can be sealed simply by pouring Epojet directly into the crack.

Epojet must be used within 40 minutes from its preparation and at 23°C.

Avoid using Epojet when the outdoor temperature and that of the substrate is less than 5°C.

Cleaning

Tools used for preparing and injecting Epojet must be cleaned immediately after use and before it hardens with solvents (ethyl alcohol, toluene, etc.).

Consumption

Sealing cracks:

• 1.1 kg/l of cavity to be filled

Bonding concrete to steel:

• 1.1 kg/m² per mm of thickness
