InjectPro-PM3811-Flex is specifically formulated for areas subject to movement with elongation of up to 275%. It is able to permeate very fine soil and fill voids between the interface area of the concrete and soil to provide excellent waterproofing capabilities for use in the creation of grout curtains behind existing concrete walls or abutments.
VOC content
0 g/L
Advantages: • Controlled, extended setting time range: 5 min – 15 minutes • Very low viscosity, excellent for penetrating into small cracks • Free from acrylamides, easy clean-up, non hazardous waste removal • Certified to NSF/ANSI/CAN 61 for potable water
Product Installation: Refer to the Aquafin InjectPro Grouting Guideline for full instructions. Injection can be accomplished from the inside of the building by drilling through the structure into the void space and soil back-filled areas. Packers are placed into pre-drilled holes and the resin is injected using the AQUAFIN-2K-Inject-Pump, or similar, under low pressure at a 1:1 ratio by volume. Start pumping at the lowest pressure setting available and increase gradually as needed. Mixing Instructions: Reaction times (gel times) can be adjusted so that the material will cure in time to provide optimum performance depending on the structure and nature of the repair. Component A "Resin" and : Pour desired amount of PM3811-Flex Resin into a clean bucket and add appropriate amount of Accelerator based on desired set time (refer to Gel Time Table below) and mix well. Component B "Hardener": Pour clean, potable water into a separate clean bucket, in the exact equal amount as the PM3811-Flex Resin. Add Hardener Powder based on Gel Time Table below and mix well. Pumping is 1:1 by volume, example mixing scenario:

InjectPro-PM3811-Flex • Comp A: Measure 100g PM3811-Flex and add accelerator 5g (=5%) Total: 105g • Comp B: Measure 5g (=5%) of the Hardener Powder and add 100g water (HP + water = 105g). Reaction Times: The reaction time for polymerization depends on the ambient temperature and the amounts of accelerator and hardener powder used to mix the components. • Reaction times can increase due to changes in the temperatures of the material in the soil. (Higher temp. = faster or shorter gel time. Lower Temp. = slower or longer gel time.) • pH of water used to mix Component-B can affect cure times. Potable water should be used for mixing material and for cleaning pump. • Avoid mixing large quantities (full pails). This will speed up the gel time. Reaction time is slower in a thin layer (e.g. in a crack). General calculation guideline: If temperature is increased in increments of 10°C (18°F), gel time will be cut in half. If temperature is decreased by increments of 10°C (18°F), gel time doubles. Average Gel Times Accelerator

*Times quoted are from laboratory data, reaction times may vary in the field. Exact reaction times should be determined on site using "cup tests" before starting injection work.
Cleaning: The pump and accessories can easily be flushed and cleaned on the jobsite by using normal detergent and clean water. Hardened material can be softened with mild cleaners (i.e., Simple Green, 409, etc.) and easily removed mechanically. Packaging: InjectPro-PM3811-Flex is supplied in a kit containing: • Component-A (Resin): •5 gal (42.7 lb) pail, (18.1 L/19.4 kg) liquid • Accelerator: •1 quart (2.13 lb) bottle, (0.86 L/0.97 kg) liquid • Component-B: •H ardener: 2.13 lb (0.97 kg) powder, Mix with 5 gal (19 L) water (provide on site) Component-A is ready for use after being mixed with the accelerator supplied. Component-B is made up at the jobsite by dissolving the hardener powder in potable water. InjectPro-PM3811-Flex is injected using a 2-component pump with stainless steel mixing parts, such as the AQUAFIN-2K-Inject-Pump.
Storage: InjectPro-PM3811-Flex should be stored in a dry enclosure in closed containers at temperatures between 50°F to 86°F. (10°C to 30°C). Protect product and packaging from inclement weather. CAUTION: Do not let the accelerator and hardener powder come in contact during storage. Store individual components separately from each other.
