Ressi Epo Inject LV 1

Ressi EPO Inject LV-1 is a two-component, solvent-free, low-viscosity epoxy resin system specially formulated for the injection and filling of cracks, voids and cavities in concrete and compatible cementitious substrates. Its low mixed viscosity allows the material to penetrate into narrow cracks and difficult-to-reach voids, while its extended working time facilitates controlled injection and filling operations, particularly where sufficient time is required for the resin to flow through the crack network.

After curing, Ressi EPO Inject LV-1 forms a hard, high-strength epoxy matrix with excellent adhesion to suitably prepared substrates. The product may be applied using suitable crack-injection equipment or by controlled gravity feeding, depending upon the nature, width, depth and orientation of the crack or void.

ADVANTAGES

• Low mixed viscosity of 500–800 cPs at 25°C for effective penetration into cracks and voids.
• Extended working time for controlled injection and filling applications.
• Two-component epoxy system with a simple 100:50 Part A: Part B mix ratio.
• High compressive and flexural strength after curing.
• Excellent bonding characteristics to properly prepared concrete and compatible cementitious substrates.
• Suitable for pressure injection or gravity-fed applications, subject to crack configuration and site conditions.
• Forms a hard and durable epoxy matrix after curing.
• Capable of penetrating areas that conventional epoxy mortars or paste-type crack fillers cannot effectively reach.
• Suitable for horizontal, vertical and overhead crack-injection applications when used with an appropriate injection method and sealing system.
• Solvent-free formulation.

WHERE TO USE

• Injection of cracks in concrete.
• Filling of fine cracks and internal voids.
• Repair of cracks in concrete floors, walls, beams, columns and slabs.
• Filling cavities and discontinuities within compatible cementitious substrates.
• Gravity filling of suitable horizontal cracks.
• Pressure injection of cracks using appropriate injection equipment and ports.
• Bonding together separated faces of stable cracks where an epoxy injection treatment is appropriate.
• Filling of suitable small voids and cavities within the recommended application thickness.
• Repair works in industrial, commercial, residential, and civil engineering structures.
• Important: The cause and condition of the crack should be established before application. Active, moving, leaking or structurally significant cracks should be assessed and treated using an appropriately designed repair system.

SURFACE PREPARATION

All cracks, voids and areas to be treated must be properly assessed and prepared prior to application. The substrate should be sound and free from dust, loose particles, oil, grease, laitance, coatings and other contaminants that may interfere with adhesion or resin penetration. Where pressure injection is required, suitable injection ports shall be positioned along the crack at appropriate intervals. The exposed crack between the injection ports should be properly sealed using a compatible epoxy sealing material to prevent leakage of the injection resin during application. Injection ports, hoses and equipment should be clean, dry and suitable for use with epoxy resin systems. For gravity-fed applications, the crack opening should be thoroughly cleaned to permit unrestricted penetration of the resin. Standing water should not be present within the crack unless the suitability of the system for the particular substrate condition has been independently established.

MIXING

Ressi EPO Inject LV-1 is supplied as a two-component system comprising Part A and Part B.

Mix Ratio – Part A : Part B = 100 : 50

Ensure that both components are accurately proportioned. Add Part B to Part A and mix thoroughly using clean and suitable mixing equipment until a completely homogeneous mixture is obtained. Mix carefully to minimize unnecessary air entrainment. Only prepare a quantity that can be applied within the available pot life. The reaction between the two components is exothermic, and the working time will reduce as the material temperature, ambient temperature, and mixed quantity increase. Do not alter the specified mixing ratio of Part A and Part B. Different Fillers and materials can be added into the mix subject to successful on-site trials. Ressichem shall not be responsible for any alteration to the actual materials supplied on site.

APPLICATION / INJECTION PROCEDURE

Pressure Injection: Install suitable injection ports along the prepared crack and seal the exposed crack surface between the ports with a compatible epoxy sealing material. Once the sealing material has sufficiently hardened, inject Ressi EPO Inject LV-1 using appropriate low-pressure or controlled-pressure injection equipment.

For vertical cracks: injection should generally commence from the lowest injection port and progress upwards. Continue injection until resin is observed at the adjacent port or until the required injection response is achieved. Close the completed port and continue progressively through the remaining ports. Injection pressure should be controlled according to the condition of the substrate, crack geometry and structural requirements. Excessive injection pressure should be avoided.

Gravity Feeding: For suitable horizontal cracks, Ressi EPO Inject LV-1 may be introduced directly into the prepared crack and allowed to penetrate under gravity. Maintain sufficient material over the crack opening during the penetration period and replenish where necessary until absorption substantially ceases.

Filling of voids and cavities: Where the product is used for filling suitable small voids or cavities, ensure that the area is properly prepared and configured to retain the resin during application. The recommended maximum casting thickness is 5 mm. Where deeper or larger sections are encountered, the proposed application should be evaluated separately before proceeding.

General Application: Do not allow mixed material to remain unnecessarily in bulk after mixing. Apply the material within the stated pot life. The viscosity and working time of the product are temperature dependent. Higher temperatures will reduce the available working time and may accelerate curing.

Cleaning:
Clean tools, mixing equipment, injection equipment and spillages using a suitable epoxy cleaning solvent immediately after application and before the material begins to harden. Once cured, Ressi EPO Inject LV-1 can generally only be removed mechanically. Appropriate personal protective equipment should be worn during cleaning operations.

LIMITATIONS

• Do not apply to unsound, contaminated or inadequately prepared substrates.
• Do not alter the specified Part A: Part B mixing ratio of 100:50.
• Do not add water, solvents or other materials to the mixed product. Unless an onsite trial has been successfully conducted.
• Pot life is temperature dependent and will decrease at elevated temperatures.
• At 30°C, the pot life of a 300 g mix is approximately 33 minutes, reducing to approximately 20 minutes at 45°C.
• The suitability of the system for active or moving cracks should be evaluated before application. A rigid epoxy system should not be used where continuing movement is expected unless specifically approved as part of the repair design.
• Cracks subjected to active water leakage require appropriate treatment before epoxy injection.
• The recommended maximum casting thickness is 5 mm. For Greater thicknesses an onsite trial should be successfully conducted.
• Actual penetration depends upon crack width and depth, crack continuity, substrate condition, temperature, injection pressure and application method.
• Structural cracks should be assessed by a suitably qualified engineer before injection.
• Trial application is recommended where substrate or site conditions are uncertain.
