Acrylate injection resin
Aquafin's InjectPro-PM3811 Series of hydrophilic acrylate injection resins
are forumlated with superior sealing characteristics. The InjectPro-3811
acrylates are environmentally safe and include:
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.
• 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 61 for potable water
• Creation of grout curtains
• Soil stabilization behind brick and concrete structures
• Construction joints, expansion joints
• Concrete precast segments, 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-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 seperate
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:
• Comp A: Measure 100g PM3811-Flex and add accelerator 5g (=5%)
• 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
5 - 6 min
6 - 8 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-Flex is supplied in a kit containing:
• Component-A: 5 gal (44.9 lb) pail (19 L/20.4 kg) liquid
• Accelerator: 1 quart (2.25 lb) bottle (0.9 L/1.02 kg) liquid
2.2 lb (1.02 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
Shelf life is 12 months in closed, original packaging, stored in a dry, cool
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 seperately from each other.
All details in particular to the suggestions for the processing and use of the
product is based on our present knowledge and experiences at the time
of printing. Depending on specific applications, in particular regarding

Safety and Handling:
InjectPro-PM3811-Flex contains no toxic components. Acrylate-ester,
acrylic monomers can irritate the eyes and skin. Sensitivity to the product
is possible if it comes in direct contact with the skin. During use wear
protective clothing, gloves, and appropriate safety goggles consistent
with OSHA regulations. Avoid eye and skin contact. Do not ingest. Refer
to Material Safety Data Sheet for detailed safety precautions. Hardened
PM-3811-Flex is environmentally safe and can be disposed of as normal
household waste. CAUTION: Do not use aluminum equipment near the
accelerator and hardener powder, they are not compatible with aluminum.
Refer to MSDS. KEEP OUT OF REACH OF CHILDREN.
