I am especially pleased with the way they took care of my floors and other property as they completed the work throughout the entire house. All of the workmen were personable, courteous, and professional.
We are applying Trenchless Cast mortar to all of the deteriorated underground cardboard air ducts. This process will give them a strong structure. We are also going to apply two applications of our rubberized Duct Armor product to completely seal the underground air duct system. The customer will no longer experience heavy debris and dust blowing out of the air duct system.
Lined a 6” sewer from an outside clean out 37’ out to the city main, 30’ in towards the house ending liner in 4” cast, also installed a Tee Liner in the hammer tap clean out lining 2’ out, 2’ in, and 2’ up the clean out riser. The customer had heavy root growth throughout the sewer also a dangerous sink hole starting to develop in the city easement due to rain/ ground water leaking through bad joints washing the earth away. The liner will seal the joints and stop roots and ground water entering
We looked at underground duct work for a customer that was getting a lot of fine dust blowing out of the registers. We found all the duct work was PVC, but the connectors and elbows were metal that were heavily rusted out allowing the backfill under the slab to enter the duct work and when the furnace would run it allowed the dust to blow up in the house. We cleaned all the ducts, applied spin cast mortar to all the bad connectors and elbows. Lastly we applied duct armor to seal the system.
Idea inspection of underground air ducts. Ducts are PVC with metal connections. Metal connections are rusting and allowing dirt and debris to enter the system. Trenchless Innovations suggests spray lining the ducts to seal the leaking joints.
