Hydrophobic, tough polyurethane grout for curtain grouting and void filling
No harmful phthalates
CSI Div. 03
03 64 00 Injection Grouting
InjectProECO-CombiGrout is a slightly flexible, tough, closed cell,
polyurethane injection grout designed for grouting into voids and
cracks. When it comes in contact with water, the grout expands and
quickly cures to a tough, flexible, closed-cell polyurethane foam that
is generally unaffected by common corrosive environments and is not
subject to shrinkage due to wet/dry cycles. InjectProECO grouts are all
environmentally friendly and formulated without harmful phthalates or
The system is comprised of an “A” component (base resin) and a “B”
component (accelerator). The “B” component is used by the applicator to
adjust the set times for various job site specific conditions.
Typical applications include filling voids and sealing cracks with differential
• Zero VOC’s - meets LEED criteria
• 100% solids, non-flammable, non-toxic permanent seal
• Hydrophobic - can be used in wet and dry environments
• Expansion up to 20 times (free foam)
• Accelerator and resin stable to -40°F (-40°C).
• Flexible and tough foam
• Pumped as a single component
• Adjustable reaction times
• Non-hazardous shipping
Reaction Times & Use of Accelerator:
The reaction time can be adjusted by the addition of accelerator “B”
into the base resin prior to pumping. The resulting profile is affected by
temperature and the amount of moisture present.
Typical reaction times:
Refer to the Aquafin InjectPro Grouting Guideline for full instructions. Mix
both the resin (Component A) and accelerator (Component B) before
• Pour the desired amount of InjectProECO-CombiGrout Resin Component
A into a clean pail.
• Measure the appropriate amount of InjectProECO-ACCELERATORCCS Component B and pour into the InjectProECO-CombiGrout
Resin, stirring until adequately mixed. Never use more accelerator than

recommended. Excess accelerator will cause significant expansion that
is prone to shrinkage. For faster reaction times please contact technical
services for information on InjectProECO-ACCELERATOR-CCS-FAST.
During injection, the grout will follow the path of least resistance. When
the material has stopped penetrating it will continue to expand against the
confines of the crack/joint and compress within itself, forming a very dense,
closed cell material stopping the leak.
InjectProECO-CombiGrout Resin: 5 gallon pails (19 L)
InjectProECO-ACCELERATOR-CCS: 32 oz. container (0.91 L)
(5% dosage per 5 gallons (19 L)of resin. For 10% acceleration use 2 x 32
oz.) (2 x 0.91 L)
Storage & Shelf Life:
Shelf life is two years when stored properly. Product is highly moisture
sensitive. Store in original sealed containers at temperature between 40°F
– 90°F (4°C – 32°C). Opened containers must be handled properly to
prevent moisture contamination.
• Temperature significantly affects viscosity. Protect material from excessive
heating and cooling prior to grouting to avoid affecting viscosity.
• If using water baths to cool or heat pails avoid splashes to prevent
water coming in direct contact with resin - this will activate the reaction.
Do not warm material or packaging above 90°F (32°C).
• Do not reseal containers of contaminated materials as it can create
• Clean up spills with adequate ventilation and appropriate personal
protective equipment. Cover the spill area with absorbent material
such as clay or vermiculite and transfer to metal waste containers.
Wash area with decontamination solution (5-10% solution of sodium
carbonate). Dispose of waste in accordance with federal, state and
