Pipe Bursting in Shaker Heights

A planned suburb with century-old pipe

Shaker Heights was built as a single composition. The Van Sweringen brothers laid out the streets, set the architectural rules, and ran the rapid transit lines out from downtown Cleveland, and the houses along Shaker Boulevard, in the Fernway and Mercer neighborhoods, and around the lakes went up between about 1912 and 1940. Beneath those houses the sewer laterals are vitrified clay in short lengths with mortar or tar joints, running from a cast-iron house drain through the foundation wall and out to the main. On some streets the sanitary main is in a rear easement rather than the street, so the lateral may leave the back of the house.

The south and east sections, Sussex, Lomond, and parts of Moreland, filled in during the 1940s and 1950s with smaller colonials and some ranches. Those laterals are still clay, with a chance of Orangeburg in the postwar builds. There is very little PVC in Shaker outside of infill houses and laterals replaced after a collapse.

Where the trouble comes from

The soil in Shaker Heights is glacial till over shale, with pockets of clay that hold water and a water table that rises near the Doan Brook valley and the lakes. The ground moves with the seasons, and a frost line near three feet lifts the first run outside the foundation every winter. After a hundred such winters the joints in a clay lateral are open, and the bells near the house are often cracked.

The trees are the defining issue here. Shaker was planted with oaks, elms, sycamores, and maples that are now among the largest street trees in the county, and their roots run far beyond the crown. Every weeping joint is an invitation, and the camera usually shows root intrusion along the whole length rather than at one spot. Parts of Shaker Heights also drain through older sewers that can surcharge in a hard rain, so a basement with a floor drain and no backwater valve can take on water when the main fills.

The right method for a long, rooted clay lateral

Cured-in-place lining is the natural fit for Shaker laterals, because the pipe is usually intact but leaking everywhere. After a camera inspection, the installer hydro jets the line and cuts the roots back to the pipe wall, then inverts an epoxy-saturated felt liner from the cleanout and cures it with hot water, steam, or UV. A single liner can run well over a hundred feet, which matters on these deep lots. Once cured, the joints are gone and the roots have nowhere to enter.

Pipe bursting becomes the answer when the camera finds a collapsed bell, a telescoped joint, or an offset the camera cannot pass. The bursting head is pulled through from a pit near the main toward a pit at the house, breaking the clay while fused HDPE follows. For one cracked bell under the front walk in an otherwise sound run, a sectional point repair cured over that spot avoids both lining the full length and digging up the walk.

Permits, inspections, and the city's standards

Shaker Heights issues sewer and plumbing permits through its building department, and the city is particular about documentation. Expect the inspector to require the pre-lining and post-cure videos and, for a bursting job, a visit before the pits are backfilled. Any work in the tree lawn or street needs a right-of-way permit, and the city's tree protection rules apply to pits dug near a street tree. Shaker's sewage flows to the Northeast Ohio Regional Sewer District system, so district connection rules apply, including prohibitions on storm water in the sanitary lateral.

If the main runs in a rear easement, ask the city where the owner's responsibility ends. In most communities it is the main itself, but the easement geometry can make that a long way from the house.

What happens on the day, and choosing an installer

A lining crew sets up at the basement cleanout, jets the line, films it, wets out the liner on site, inverts it, and cures it. Drains are off for most of the day. Branch connections, such as the kitchen or a basement bath, are reinstated with a robotic cutter and the finished pipe is filmed. A bursting crew brings an excavator, a pulling rig, and a second day for restoration.

Ask each bidder for the full camera footage, a scope that names the footage of pipe and the liner thickness, and the warranty. To compare contractors whose training and insurance have been verified, find a verified CIPP contractor and request a reference from a Shaker Heights or Cleveland Heights job with a run of similar length. A crew that has lined under a slate walk and a hundred-year-old oak will know what to expect here.

Pipe Bursting in Shaker Heights

How pipe bursting works

A steel cable is threaded through the old sewer line from a pit at one end to a pit at the other. A cone-shaped bursting head, with new high-density polyethylene pipe fused to it, is pulled through by a hydraulic unit. The head splits the old clay or cast iron outward into the soil and the new pipe follows in the same alignment at the same depth. The result is a single fused length of pipe with no joints for roots to find.

When bursting is the right call

• Collapsed sections — a liner needs a host pipe to hold its shape; a collapsed run has none.
• Bellies — a low spot that holds water stays a low spot after lining. Bursting lays new pipe on a fresh bed.
• Undersized lines — bursting can upsize a 3-inch lateral to 4 inches; lining slightly reduces diameter.
• Badly deformed pipe — Orangeburg that has flattened, or cast iron with most of its bottom gone.

What the job looks like

One pit at the house or cleanout, one at the property line or the street connection, each a few feet square. Utilities that cross within a foot or two of the sewer path are located and potholed first. The pull takes an hour or two; the whole job, including fusing, connections, inspection and backfill, is usually one day.

Permits and the street

If the downstream pit is in the sidewalk, parkway or street, a right-of-way permit and restoration to city standards are required in addition to the plumbing permit. If the connection at the main is replaced, the city inspects it before the pit closes. Confirm who is handling this before work starts.
