After working with all of their competitors, we’ve used HJ3 for the past 7 years, because they provide the engineering and on-site support required to execute these custom applications, and their materials last.
We installed HJ3’s CarbonSeal Tank Repair System as a 3-year repair. That was 12 years ago, and it is still doing great.
We’ve used hundreds of thousands of square feet of HJ3’s CarbonSeal Systems to revitalize our 100-year-old facility over the past 10 years with great success.
CarbonSeal was recommended as an extremely strong system, that installs quickly and protects against Hydrogen Sulfide gas found in most sewage systems… We’ve always had good response from HJ3 and success with their systems.
