Sectional Point Repair in Redlands

Redlands was built on oranges and old money, and it shows in the housing. The city's historic core, from the Smiley Park district west of downtown through the streets around the Kimberly Crest estate and south toward the hills, holds hundreds of Victorian, Craftsman, and Mediterranean Revival homes from the 1880s through the 1920s, many on original lots with original trees. Around that core are 1920s through 1950s neighborhoods, postwar tracts east toward Mentone and north of the 10, and hillside homes in South Redlands that climb toward the San Timoteo Canyon badlands. The University of Redlands anchors a district of older houses converted to student rentals. Few places in the Inland Empire have so many century-old sewer laterals still in daily service.

Trenchless sewer repair matters more here than almost anywhere in the county because of what sits on top of those laterals: brick walks, heritage trees, gardens, and in the historic districts, hardscape that cannot simply be replaced with new concrete. The Inland Empire trenchless service region outlines the broader coverage area. What follows is what Redlands owners should know.

Grove soil, canopy, and century-old pipe

Most of Redlands is underlain by the deep, well-drained loam that made it ideal citrus ground. It digs easily and does not swell much, but it holds enough moisture to support an extraordinary tree canopy, and roots are the dominant cause of lateral failure. Pepper trees, camphors, magnolias, jacarandas, oaks, sycamores, and the remnants of grove-era windbreak eucalyptus all send roots toward leaking joints. In South Redlands the ground becomes firmer and more clayey, with sandstone and slope creep in the hills that stresses pipe over time.

Pipe follows the housing era. The 1880s through 1920s homes have vitrified clay laterals with mortar joints in short sections, typically shallow, often with a raised foundation and a crawl space where the building drain is cast iron. The 1920s through 1950s neighborhoods are also clay, with some Orangeburg fiber pipe in the postwar tracts. Cast iron is standard under the slab-on-grade houses of the 1960s and 1970s, and ABS plastic takes over by the late 1970s in the newer areas north of the freeway and out toward Mentone. Converted rentals near the university combine original clay with far more flow than the pipe was sized for.

Which method fits which problem

Begin with hydro jetting to clear roots and scale, then a camera inspection and a surface locate. In the historic districts the locate also establishes which trees and hardscape the line passes under, which shapes the whole access plan.

• CIPP lining is the natural choice for Redlands clay: rooted and leaking at every joint but still round and continuous. The liner cures into a seamless pipe inside the old one, roots lose their entry points, and the garden stays intact. The what cured-in-place pipe is explains the material and the curing process.
• Pipe bursting fits Orangeburg, collapsed clay, and runs with significant bellies. It needs a pit at each end, which the crew sites to spare trees and walks.
• Sectional point repair fits one broken joint under a driveway or a single crushed section of newer pipe.
• Spin-cast lining fits the cast-iron building drains under slabs and in crawl spaces, and the larger lines serving downtown commercial buildings and apartment properties near campus.

Permits, locating, and responsibility

Redlands is incorporated and operates its own sewer collection and treatment system, so plumbing and encroachment permits come from the city. The owner is responsible for the lateral from the building to the connection at the city main, including the portion under the parkway and street, and right-of-way work requires an encroachment permit and traffic control. Unincorporated areas toward Mentone go through San Bernardino County Land Use Services. Every excavation, even a small pit, starts with a DigAlert 811 notification and utility marks. Redlands has no general point-of-sale sewer inspection, but buyers of historic homes almost always order a sewer scope, and a lined lateral with video documentation is a real selling point. Street trees in Redlands are protected, so any work near them should be planned accordingly.

What an estimate visit covers

Expect a camera run, a surface locate with depths, attention to trees and hardscape, and a written scope naming the method, footage, and access points. Keep the video and the sketch.

Sectional Point Repair in Redlands

Fix the spot, not the line

A sectional point repair treats a short length of pipe, usually two to six feet, instead of the whole lateral. A short fiberglass or felt liner saturated with resin is positioned over the defect on an inflatable packer, pressed against the wall, and cured in place. The rest of the line is untouched. Where the defect cannot be lined, the alternative is a small excavation at that exact spot, made possible because the camera and locator have already marked it to within inches.

When it makes sense

One identifiable defect, or two or three close together, on a line whose remaining footage is sound: a joint crushed when a driveway was poured over it, a single root-intruded joint under a parkway tree, a break where the lateral crosses another utility trench, or the transition where under-slab cast iron meets the clay or ABS running to the street.

When it does not

If the camera shows the same defect at every joint, or channeling along the whole bottom of a cast iron line, fixing one spot moves the next backup a few feet down the pipe. A full liner costs more today and far less over the next few years.

A fair test

Ask to see footage of the pipe on both sides of the proposed repair. If it is clean for the full run, a point repair is honest and economical. If it is not, ask why a full liner was not proposed.
