ETI Injection Epoxy 

ETI-LV  ETI-GV  Crack Pac  Crack Repair - ETI

ETI injection epoxies are specially designed formulations for the injection and repair of cracks in concrete. ETI epoxies are twocomponent, 1:1 ratio, high solids formulations. They are available in 650ml side-by-side cartridges and are dispensed through a static mixing nozzle using a manual or pneumatic dispensing tool. ETI is availablein two viscosities: ETI-LV (low viscosity) and ETI-GV (gel viscosity) to handle a wide range of crack widths. Properly installed, they provide a repair that is both waterproof and high strength (structural).

Features:

  • Chemically bonds with the concrete to provide a structural repair (meets the quirements of ASTM C-881 as a structural repair epoxy) 
  • Seals the crack from moisture, protecting rebar in the concrete from corrosion and moisture damage 
  • Both viscosities formulated for maximum penetration under pressure 
  • Side-by-side cartridge dispensing provides reliable mixing and ratio control when used with the New Simpson Strong-Tie® Opti-Mix® static mixing nozzle 
  • Eliminates the need for expensive bulk dispensing equipment. Either formulation can be dispensed using a manual or pneumatic dispensing tool (ETI-LV requires the use of the Opti-Mix® nozzle, model EMNO22, which is included with the cartridge) 
  • Black and white components allow easier verifi cation of mixing than systems utilizing same color components. The mixed epoxy is gray for a better color match with the concrete for exposed conditions 
  • Suitable for pressure injection or gravity-feed applications. 
  • Non-shrink material resistant to oils, salts and mild chemicals 

ETI-LV Low Viscosity Injection Epoxy:

  • Low viscosity epoxy (1790 cps) for repair of fi ne to medium width cracks 0.4~6.4mm in width 
  • Low surface tension allows the material to effectively penetrate narrow cracks 
  • Suitable for structural repairs 

ETI-GV Gel Viscosity Injection Epoxy:

  • Gel viscosity epoxy for repair of medium cracks 2.4~6.4 mm width. 
  • Decreases in viscosity under pressure for increased fl owability. 
  • Suitable for structural repairs. 

Application:

Epoxy-Tie® injection epoxies are suitable for repairing non-moving cracks in concrete walls, fl oors, slabs, columns and beams. They can be used to inject cracks in damp or wet conditions with excellent results. Apply to concrete 4°C or above. For best results, warm material to 15°C or above prior to application.

Take appropriate precautions when handling flammable solvents. Solvents may damage surface to which they are applied.

Expoxy-Tie Crack Repair Method Statement:

Note Important: These instructions are intended as recommended guidelines. Due to the variability of fi eld conditions, selection of the proper material for the intended application and installation are the sole responsibility of the applicator.

Epoxy injection is an economical method of repairing non-moving cracks in concrete walls, slabs, columns and piers and is capable of restoring the concrete to its pre-cracked strength. Prior to doing any injection it is necessary to determine the cause of the crack. If the source of cracking has not been determined and remedied, the concrete may crack again.

Materials:

  • ETI-LV for repair of fi ne to medium-width cracks (Suggested width range: 0.4mm–6mm). 
  • ETI-GV for repair of medium-width cracks (Suggested width range: 2.4mm–6mm) 
  • E-Z-Click™ injection ports, fi ttings and other suitable accessories. 

Preparation of the Crack for Injection:

Clean the crack and the surface surrounding it to allow the epoxy to bond to sound concrete. At a minimum, the surface to receive paste-over should be brushed with a wire brush. Oil, grease or other surface contaminates must be removed in order to allow the paste-over to bond properly. Take care not to impact any debris into the crack during cleaning. Using clean, oil free compressed air, blow out the crack to remove any dust, debris or standing water. Best results will be obtained if the crack is dry at the time of injection. If water is continually seeping from the crack, the fl ow must be stopped in order for epoxy injection to yield a suitable repair. Other materials such as polyurethane resins may be required to repair an actively leaking crack.

For many applications, additional preparation is necessary in order to seal the crack. Where a surfacing material has been removed using an acid or chemical solvent, prepare the crack as follows:

  1. Using clean, compressed air, blow out any remaining debris and liquid. 
  2. Remove residue by high-pressure washing or steam cleaning. 
  3. Blow any remaining water from the crack with clean compressed air. 

If a coating, sealant or paint has been applied to the concrete it must be removed before placing the paste-over epoxy. Under the pressure of injection these materials may lift and cause a leak. If the surface coating is covering the crack, it may be necessary to route out the opening of the crack in a “V” shape using a grinder in order to get past the surface contamination.

Sealing of the Crack and Attachment of E-Z-Click™ injection ports:

Sealing of the Crack and Attachment of E-Z-Click™ injection ports

  1. To adhere the port to the concrete, apply a small amount of epoxy around the bottom of the port base. Place the port at one end of the crack and repeat until the entire crack is ported. As a rule of thumb, injection ports should be placed 200mm apart along the length of the crack. Important: Do not allow epoxy to block the port or the crack under it, this is where epoxy must enter the crack. 
  2. Using a putty knife or other paste-over tool, generously work epoxy along the entire length of the crack. Take care to mound the epoxy around the base of the port to approximately 6mm thick extending 25mm out from the base of the port and to work out any holes in the material. It is recommended that the paste-over should be a minimum of 5mm thick and 25mm wide along the crack. Insuffi cient paste-over will result in leaks under the pressure of injection. If the crack passes completely through the concrete element, seal the back of the crack, if possible. If not, epoxy may be able to run out the back side of the crack, resulting in an ineffective repair. 
  3. Allow the paste-over to harden before beginning injection. 

Injection Procedure for ETI-LV and ETI-GV Injection Epoxy:

  1. Follow cartridge preparation instructions on the cartridge label. Verify that the material fl owing from the Opti-Mix® mixing nozzle is a uniform gray color for ETI-LV and ETI-GV. 
  2. Attach the E-Z-Click™ fi tting to the end of the nozzle by pushing the tubing over the barbs at the end of the nozzle. Make sure that all ports are pushed in to the open position. 
  3. Attach the E-Z-Click™ injection fi tting to the fi rst E-Z-Click™ port until it clicks into place. Make sure that the heads of all the ports are
    pushed in to the open position. In vertical applications, begin injection at the lowest port and work your way up. In a horizontal application start at one end of the crack and work your way to the other end.
     
  4. Inject epoxy into the fi rst port until it will no longer fl ow into the crack. If epoxy shows at the next port and the fi rst port still accepts material, close the second port and continue to inject into the fi rst port until it accepts no more epoxy. Continue closing ports where epoxy appears until the fi rst port refuses epoxy. When the fi rst port reaches the point of refusal, brace the base of the port and pull out gently on the head of the port to close it. Pulling too hard may dislodge the port from the surface of the concrete, causing a leak. Depress the metal tab on the head of the E-Z-Click fi tting and remove it from the port. 
  5. Go to the last port where epoxy appeared while injecting the fi rst port, open it, and continue injection at this port. If the epoxy has set up and the port is bonded closed, move to the next clean port and repeat the process until every portion of the crack has refused epoxy. 

While this method may appear to leave some ports uninjected, it provides maximum pressure to force the epoxy into the smaller areas of the crack. Moving to the next port as soon as epoxy appears will allow the epoxy to travel along the wider parts of the crack to the next ports rather than force it into the crack before it travels to the next ports.

Injection Tips:

Injection Procedure for ETI-LV and ETI-GV Injection Epoxy

  • If using a pneumatic dispensing tool, set the tool at a low setting when beginning injection and increase pressure if necessary to get the epoxy to fl ow. 
  • For narrow cracks it may be necessary to increase the pressure gradually until the epoxy begins to flow. It may also be necessary to wait a few minutes for the epoxy to fill the crack and travel to the next port. 
  • If desired, once the injection epoxy has cured, remove the injection ports and paste-over epoxy. The epoxy can be removed with a chisel, scraper, or grinder. Using a heat gun to soften the epoxy is recommended when
    using a chisel or scraper.
     
  • Mixing nozzles can be used for multiple cartridges as long as the epoxy does not harden in the nozzle.
