Sewer Pipe Lining (CIPP) in Ravenna City

Ravenna's housing eras and their pipes

Ravenna has been the county seat since the early 1800s, and its core, the blocks around the courthouse, along Main Street, Chestnut Street and the side streets off Route 59, was built out between the 1860s and the 1920s. The laterals under those homes are vitrified clay in short jointed lengths, often connected to a cast iron run through the foundation wall. Many have never been replaced.

The city grew again after the Second World War, with ranches and bungalows filling the streets toward the north and south edges and along Route 14. Those 1950s and 1960s lots may hold clay, Orangeburg fiber pipe or asbestos-cement, depending on the builder. Subdivisions from the late 1970s on, and the newer housing toward the township line, generally have PVC laterals that give far less trouble.

Clay till, a long freeze and the old combined sewers

Ravenna sits on flat glacial till with a high clay content, and the ground drains slowly. Trenches dug for laterals a century ago fill with water every spring, and the frost line in a hard winter reaches three feet. Saturated clay heaves as it freezes, lifting a jointed pipe unevenly year after year until the lateral has offset joints and bellies that trap water and solids.

The sugar maples and silver maples that line the older streets, and the sycamores along the creeks and the low ground toward the reservoirs, send roots into every weeping joint. A camera inspection on a Victorian-era lot usually shows root curtains at most joints and groundwater trickling in at the rest. In the downtown core the sewers are combined, carrying storm water and sanitary flow together, so a heavy storm surcharges the main and pushes water back up any lateral with open joints or lost grade into the basement.

Lining, bursting or a point repair in Ravenna

A camera inspection and a locate always come first, and the installer should provide the video. For the common case, a clay lateral that is cracked, rooted and leaking but still round, cured-in-place pipe lining is the usual recommendation. The crew cuts roots, hydro jets the pipe clean, then inverts or pulls an epoxy-saturated felt liner through the whole run and cures it with hot water, steam or UV light. The liner is a continuous, jointless pipe that stops both roots and infiltration.

When the camera cannot pass a collapsed or crushed section, or a joint has dropped too far for a liner to bridge, pipe bursting is the answer. A pit at the house and a pit near the main let a bursting head split the old clay while fused HDPE is pulled in behind it. A single failed joint on an otherwise sound lateral is best handled with a sectional point repair, a short liner cured over that spot.

Permits, the right-of-way and inspection

Within Ravenna the sewer permit and inspection come from the city's engineering and utility departments, and a pit in the street, sidewalk or tree lawn requires a right-of-way permit as well. Properties outside the corporation line in Ravenna Township may be on Portage County sewer and go through the county water resources department. The inspector wants to see bursting pits open before backfill and the post-cure video on a lining job. Where a lateral connects to a combined main, the inspector may also check that no footing or roof drains remain tied into the sanitary side.

What the day looks like and how to pick an installer

Plan on water being off for several hours, a truck and reel at the curb, and a crew at the cleanout or a small pit by the foundation. Lining is normally done by late afternoon; bursting may need a second day with restoration. Before hiring, get the camera video, a written method and the product name of the liner or pipe. To compare candidates, find a verified CIPP contractor and favor crews that have lined century-old clay in Ravenna's older neighborhoods, where the transition from cast iron to clay at the foundation and the infiltration at the joints both need careful handling.

How cured-in-place lining works

A felt or fiberglass tube is saturated with resin, pulled or inverted into the cleaned host pipe, pressed against the wall with air or water, and cured with hot water, steam or UV light. When it hardens you have a new, jointless pipe inside the old one. The liner takes up a small amount of diameter, but its smooth wall flows better than corroded cast iron or offset clay. Lateral liners are typically rated for a 50-year service life.

What has to happen first

A camera inspection to map the line and every branch connection, hydro jetting to strip roots and scale so the resin bonds to clean pipe, and measurement so the liner is cut to length. After the cure, branch connections are reopened from inside with a robotic cutter and the line is filmed again.

When lining is the right fix

• Root intrusion at joints, longitudinal cracks, small offsets, pinholes or channeling in cast iron — on a pipe that is still round and holding grade.
• Lines under slabs, driveways, mature landscaping or streets, where the cost of a trench is mostly the cost of restoring what is above it.
• Coastal and high-water-table lots where an open trench means dewatering and shoring.

When it is not

Collapsed pipe, bellies that hold standing water, and lines that were undersized to begin with. A liner follows the host pipe's shape, so a bad shape stays bad. Those lines get pipe bursting or a spot replacement. Under-slab cast iron with several tight bends usually gets a spray-applied liner rather than felt.

Questions worth asking

What resin system and cure method will be used, what the liner's rated life is, whether the branch connections were counted, who pulls the permit, and whether you will receive the before-and-after video. A contractor who does this every week answers all five without hesitation.
