Trenchless Innovations is proud to provide effective, non-invasive air duct & sewer repair services to the residents of Lombard, IL and the surrounding areas.

Lining underground air ducts makes a huge difference if the ducts are old, cracked and broken. Duct lining restores the broken duct to a like-new condition, while eliminating the mess and costly restoration work that comes with traditional digging.

Sewer lining is a long-lasting solution to repeated backups caused by a broken sewer line. Lining your sewer creates like-new pipes in place of the broken ones, sealing joints and cracks in the pipe that allow tree roots and other debris to enter them. Sewer lining ensures a smooth, free flowing sewer and lasts so long that it even comes with a 50-year standard warranty!

Underground air duct sealing is a complete, effective way to repair deteriorated underground air ducts. Our process involves no messy digging or restoration work afterward. Instead, our liner is inserted through the floor registers of your home, completely covering the entire length of your ducts, if necessary. Our duct sealing process eliminates holes and cracks in pipes and joints that allow sand, dust and other debris to enter your home and pollute the air within it.

Televised ducts under slab floor. Ducts are concrete ducts with metal fittings and connections that are severely rusted. Suggest spin cast mortaring metal fitting then spray lining ducts with Duct Armor duct lining material to encapsulate the concrete ducts. Homeowner had experienced a previous sewer line break and it got into the ducts.

Televised ducts under slab floor. Ducts are concrete ducts possibly Transite with asbestos with metal fittings and connections. Metal distribution boxes are very rusted and need to be mortared but there is no access to them.

We are applying our Trenchless cast mortar to all of the heavily deteriorated connections and elbows in the underground air duct system. This will give these areas a strong concrete structure and dirt and debris will no longer enter from these points. We are then going to apply two applications of our rubberized duct lining material to the entire system. The underground air duct system will be completely sealed and debris will no longer flow throughout the air vents.

Video inspection of underground air ducts. Ducts are concrete with metal connections and fittings. Customer is getting water in the ducts. Customer needs to extend downspouts around the house then also fix gutters that are leaking. Customer should also install a sump pit and pump to control the water. Once the water issue is resolved the ducts should be spray lined with Duct Armor duct lining material to encapsulate the concrete pipes.

We came out to televise some underground duct work for a customer to find the lines were filled with water and mud/dirt. We recommended running the downspouts out away from the house to lower the water table from rising up under the slab allowing water to enter the ducts. Sure enough a few weeks later the water was gone, then we were able to clean all the duct work, also spin cast mortar the bad metal pipes/ connections for structure. Finally we applied duct armor to seal the HVAC system.
