Geotechnical Polyurethane Grout

CJGrout polyurethane grouts are a collaboration between CJGeo, one of the country’s leading polyurethane grouting contractors, and NCFI, an unparallelled polyurethane manufacturer.  By leveraging CJGeo’s grouting expertise and NCFI’s polyurethane chemistry and manufacturing expertise, CJGrout offers a diverse portfolio of customized polyurethanes capable of solving the most challenging geotechnical, infrastructure and structural grouting needs.

Each CJGrout has unique properties developed around solving unique problems.  Polyurethane grouts offer substantial benefits over cementitious grouts, such as improved cleanliness, reduced loads on underlying soils, minimal downtime, and significant time savings.  Among geotechnical polyurethanes, CJGrout excel in that each grout has been developed by chemists working hand in hand with an experienced contractor to solve specific, real-world geotechnical & infrastructure problems.  CJGrout isn’t just rebranded spray foam.

Why CJGrout?


Time is money.  Minimizing downtime and speeding return to service is a key benefit of choosing CJGrout polyurethane grouts.  Unlike high mobility cement-based grouts which may take hours, if not days, to accept traffic, CJGrout polyurethane grouts can take traffic within minutes of placement.  Even rail traffic.


Settlement usually starts with poorly consolidated underlying soils.  CJGrout polyurethane grouts are significantly lighter than traditional cement based grouts, but still provide excellent bearing capacities.  By using polyurethane grout, minimal burden is placed on underlying soils, helping to reduce the likelihood of resettlement from increases in dead loads.  The half life of geotechnical polyurethanes is generally considered to be greater than 150 years.
