DIRECTIONS FOR USE

Mixing Procedure:
Put PENETRON INJECT^TM - PART B (LIQUID) into the mixing bucket. Add water to the bucket and mix. Remove 10% of this mixture and store for later re-addition. Slowly add PENETRON INJECT^TM - PART A (POWDER) to the 90% mixture mixing continuously with a suitable mixing tool. Mix for at least 2 minutes until a smooth, homogeneous, lump free mix is achieved. Add the stored 10% mixture to the combined powder/liquid mix and continue to mix for an additional one minute.

This completed mixture should have a viscosity of approximately 30 seconds in a DIN 4 mm cup. In cases where an extremely low viscosity mix is needed (e.g., to fill very fine cracks), an additional 0.5 l (0.5 qt) to a maximum of 1 l (1 qt) of water can be added until a viscosity of 18 DIN-seconds is reached.

Once this mix is poured into the funnel of the injection pump, it is ready to be injected. It is helpful to slightly agitate the mix from time to time, approximately every 10-15 minutes, in case all of the mix is not used immediately. Initiation of the curing reaction can be noted by an increase in the viscosity. To avoid solidification in the equipment, the remaining mix should be cleaned out of the funnel, pump and injection tubes.

Pot life times are based on a temperature of 20°C (68°F). In higher temperatures the pot life and workability will be reduced. In such cases more of PENETRON INJECT^TM - PART B (LIQUID) can be added with a corresponding and equal reduction in mix water. Penetron International, Ltd. strongly recommends trial testing, should such changes from the standard instructions be necessary.

Application:
PENETRON INJECT^TM can be applied using most standard injection procedures; however, as each individual application case will have its own unique parameters, please contact your Penetron technical representative for the most accurate support for your project. The following are the typical
application steps:
Step 1: Prepare crack to receive repair materials by sawcutting along the length of the crack at a width of approximately 19-25 mm (3/4-1”). Sawcut should be a reverse “V” or “U” shaped channel to avoid repair materials from popping out.
Step 2: Remove the concrete in the crack area to a depth equal to the width of the sawcut or 50% deeper. (e.g., if a 25 mm (1") wide sawcut is made, a 38 mm (1.5”) depth channel should be cut out).
Step 3: Clean the sawcut channel with a water pressure washer (3000 psi min).
Step 4: Drill holes to receive the injection packers. Diameter and depth of the holes will be as defined by the type and style of injection packer used. Holes should be spaced out at 25-38 cm (10-15”).
Step 5: Place and tighten the injection packers.
Step 6: Partially fill the bottom of the channel and around each injection packer with PENEPLUG® so escaping water is able to flow only through the injection packers.
Step 7: Brush on a slurry of PENETRON® on PENEPLUG® and along the remaining visible channel surfaces, as well as 7-15 cm (3-6”) on the sides of the channel.
Step 8: As soon as the PENETRON® slurry is dry to the touch but still green, fill the remaining channel with PENECRETE MORTAR^TM. PENECRETE MORTAR^TM should be dry packed into the channel using a wood block and hammer to ensure a tight fit with no voids.
Step 9: Allow PENETRON® / PENECRETE MORTAR^TM / PENEPLUG® to completely set and dry for 2-3 days. During this time, water may flow freely through the injection packers.
Step 10: Start injecting PENETRON INJECT^TM from the lowest injection packer. Pump until PENETRON INJECT^TM starts to flow from the next highest injection packer or until the pressure rises (maximum pressure - 5 bar). Close the first injection port and begin filling from the second injection packer. Follow this sequence until the entire length of the repair is filled.
Step 11: Allow PENETRON INJECT^TM to cure and harden for at least 2 days. At this point, a visual inspection can confirm that all leaks have been stopped and the injection packers can be loosened and removed.
Step 12: Dry pack all holes left by the injection packers with PENECRETE MORTAR^TM. Use a dowel to tightly compress PENECRETE MORTAR^TM into the holes.
