Manhole Relining

Duke’s is a proud applicator of Quadex materials including the revolutionary Geokrete geopolymer manhole lining solution that works in environments down to 1pH. Our trenchless rehabilitation technique restores even the most seemingly far-gone structures making them as good as new.

Chimney Sealing

There is a lot of debate within the coatings industry regarding the correct way to apply a chimney sealant. We have been a trained and certified applicator of Sealing System’s Flex Seal Utility Sealant for 10 years and have experience working on over 1000 manhole chimneys. Proper preparation is critical to a long-lasting application. We take every important aspect into consideration, by first sand blasting and cleaning the casting and chimney section. Our technicians then put on a primer and brush apply the top coat. It may take us a little longer to do it, but the results are second to none. Our utility sealant can be used in a number of applications including wet wells, hatch door openings and more. Specify the best!

Pressure Grouting

Duke’s is trained and certified by Avanti for all of their manhole pressure grouting products including AV100. We pull up to the job in our grouting rig ready to seal up the most persistent leaks in your structures. Check out our video using Sealing Systems, Aqua Seal Hydrophobic Urethane Grout.
