Aquafin's InjectPro-PM3811 Series of hydrophilic acrylate injection resins
are formulated with superior sealing characteristics. The InjectPro-3811
acrylates are environmentally safe and include: InjectPro-PM3811
SoilStabilizer, InjectPro-PM3811-Flex, InjectPro-PM3811-Fast, and
1.0 – 1.2 g/cm³
Clear, low viscous liquid
InjectPro-PM3811-SoilStabilizer is designed for permeating very fine soil
and filling narrow voids between the interface area of the concrete and
substrate. It can also be used for creation of grout curtains behind existing
concrete walls or abutments and homogenous membranes beneath
concrete floors. The very low viscosity guarantees that even the smallest
of voids, soil fractures, honeycombs, capillaries and hairline cracks will be
completely filled and sealed with injection material.
• Controlled, extended setting time range: 4 min – 14 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
• Creation of grout curtains
• Soil stabilization behind brick and concrete structures
• Construction joints, concrete precast segments
• Non-active (static) hairline and micro-cracks
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.
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": Pour desired amount of PM3811-SoilStabilizer
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-SoilStabilizer Resin.
Add Hardener Powder based on Gel Time Table below and mix well.

Pumping is 1:1 by volume, example mixing scenario:
• Comp A: Measure 100g PM3811-SoilStabilizer and add
accelerator 5g (=5%) Total: 105g
• Comp B: Measure 5g (=5%) of the Hardener Powder and add
100g water (HP + water = 105g).
The reaction time for polymerization depends on the ambient temperature
and the amounts of accelerator and hardener powder used to mix the
• 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
Average Gel Times
4 - 5 min
5 - 7 min
*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
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.
InjectPro-PM3811 SoilStabilizer is supplied in a kit containing:
• Component-A (Resin):
gal (42.7 lb) pail, (18.1 L/19.4 kg) liquid
quart (2.13 lb) bottle, (0.86 L/0.97 kg) liquid
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-SoilStabilizer is
injected using a 2-component pump with stainless steel mixing parts, such
as the AQUAFIN-2K-Inject-Pump.
Shelf life is 24 months in closed, original packaging, stored in a dry, cool
InjectPro-PM3811-SoilStabilizer 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
