Aquafin InjectPro-PM3811-Flex 3 Component Kit

Features and Benefits

Aquafin InjectPro-PM3811-Flex is a 3-component hydrophilic acrylate injection resin system specifically formulated for areas subject to movement with elongation of up to 351%. InjectPro-PM3811-Flex's ultra-low viscosity allows it to permeate deeply into many kinds of soils and hairline cracks and offers adjustable curing times to allow for better control over depth of penetration. InjectPro-M3811-Flex is environmentally friendly, containing zero VOCs and emitting no fumes, making it safer to use in confined spaces.

• Controlled, extended setting time range: 20 seconds - 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

Application Information

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.

Typical Applications

• Creation of grout curtains
• Soil stabilization behind brick and concrete structures
• Crack injection
• Construction joints, expansion joints
• Concrete precast segments

Cure Rates

Cure times (gel times) can be adjusted to provide optimum performance depending on the structure and nature of the repair. 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.)
• The 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).

Mixing

1. Pour desired amount of Component-A Resin into a clean bucket and add appropriate amount of Accelerator based on desired set time (refer to Gel Timetable above) and mix well.
2. Pour clean, potable water into a separate clean bucket, in the exact equal amount as the Component-A Resin. Add Hardener Powder (refer to Gel Timetable above) and mix well.
3. Pumping is 1:1 by volume.

Example mixing scenario:

• 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).

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

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 SealBoss IP2C Acrylate Gel Injection Pump.
