Imagine tearing open walls from the basement to the roof just to replace one corroded drain pipe. That’s what fixing vertical plumbing stacks used to mean—weeks of demolition, displaced tenants, sky-high costs, and massive disruption. For multi-story buildings, condos, hospitals, and commercial properties across Louisiana, failing vertical drain stacks were nightmares waiting to happen.
Vertical stack lining changes everything. This advanced trenchless technology repairs deteriorating soil stack pipes, sewer risers, and waste stacks from the inside—no demolition required. At Pelican Underground, we specialize in this precise, proven method that saves Louisiana property owners time, money, and headaches. The Pelican Underground team features professionals certified by NASSCO in PACP, MACP, and LACP standards, delivering high-quality trenchless sewer repair services throughout Louisiana, Mississippi, and Alabama. Alexandria and Central Louisiana residents benefit from our professional vertical stack lining, CIPP services, and drain cleaning for multi-story buildings and residential properties.
We provide trenchless sewer repair services in Covington and the Northshore region, focusing on solutions for aging pipe systems in established neighborhoods. Houma and Terrebonne Parish receive expert trenchless services from our team, addressing unique coastal challenges with no-dig pipe repair solutions. Slidell‘s multi-family residential and commercial buildings rely on our dependable stack lining and pipe repair services.
Vertical stack lining is a specialized form of CIPP (Cured-In-Place Pipe) technology designed specifically for vertical drain and waste pipes that run through multiple floors of buildings. Instead of replacing the entire stack by cutting through walls, floors, and ceilings, we create a new pipe inside your existing one.
Vertical Stack Lining is one of our specialized trenchless rehabilitation techniques for critical vertical assets like manholes and wet wells, forming part of Pelican Underground’s comprehensive suite of commercial underground infrastructure solutions for non-disruptive repair and asset longevity.
The process is remarkably straightforward, though it requires specialized equipment and expertise:
Step 1: Inspection and Preparation
We start with video camera inspection to assess your stack’s condition. Then we perform thorough cleaning. Precede vertical stack installation with industrial-grade drain cleaning to ensure optimal adhesion and performance of renewal liners in contaminated environments.
Step 2: Liner Installation
We insert a flexible liner saturated with epoxy resin into your vertical stack. The liner gets positioned precisely from top to bottom, ensuring complete coverage of all damaged sections.
Step 2: Liner Installation
We insert a flexible liner saturated with epoxy resin into your vertical stack. The liner gets positioned precisely from top to bottom, ensuring complete coverage of all damaged sections. access points. Most installations cure in 2-6 hours.
Step 3: Curing Process
Depending on your building’s needs, we use hot water curing, steam curing, or UV curing to harden the epoxy. The curing method depends on stack height, diameter, and access points. Most installations cure in 2-6 hours.
Step 4: Final Inspection
Once cured, we trim excess liner at connection points and perform final video inspection to verify a perfect installation. Your new pipe is ready for immediate use.
The entire process typically completes in 1-3 days, depending on the stack’s height and complexity. No walls torn open. No floors ripped up. No tenants displaced.

Louisiana’s older buildings often feature cast iron stacks that corrode from the inside out. By the time you notice rust stains or leaks, the damage is extensive. Traditional cast iron stack rehabilitation meant gutting the building. Cured-in-place lining provides structural renewal that actually strengthens the existing pipe while stopping all leaks.
For complete infrastructure rehabilitation, combine vertical stack lining with trenchless pipeline renewal for horizontal pipes to create seamless, end-to-end system protection.

Vertical stack lining is a trenchless repair method that creates a new pipe inside deteriorating vertical drain and waste stacks without demolition. A flexible liner saturated with epoxy resin is inserted into the existing stack, then cured in place using heat or UV light. This creates a seamless, structural pipe that renews the stack for 50+ years while avoiding the cost and disruption of traditional replacement.
The process begins with video inspection and thorough cleaning of the existing stack. A custom-sized liner impregnated with epoxy resin is then inserted from the top or bottom access point and positioned throughout the vertical stack. The liner is inflated to press against the pipe walls, then cured using hot water, steam, or UV light. Once hardened, the epoxy forms a new structural pipe bonded to the existing stack, sealing all cracks and preventing further deterioration.
Absolutely. Stack lining typically costs 40-60% less than traditional replacement when you factor in demolition, reconstruction, tenant displacement, and lost rental income. Projects complete in days instead of weeks. Buildings stay operational throughout. The new liner lasts 50+ years with proper maintenance. For multi-story buildings, the ROI is compelling—you get a brand-new pipe system without gutting your building.
The best curing method depends on your specific situation. Hot water curing is most common, offering reliable results and reasonable cure times (4-6 hours). Steam curing works well for taller stacks and provides excellent heat distribution. UV curing is fastest (1-2 hours) but requires clear sight lines and special equipment. Ambient cure resin works for situations where introducing heat or UV is impractical, though cure times are longer (12-24 hours).
Yes, CIPP lining is ideal for condominium vertical stacks. It’s specifically designed to minimize resident disruption—no walls opened, no tenants displaced, and most units remain fully operational during installation. Work typically happens during regular business hours. The process is cleaner and quieter than traditional replacement. Many condo associations choose stack lining specifically because it avoids the special assessments, displacement issues, and conflicts that traditional replacement creates.
Vertical stack lining typically costs $150-$400 per linear foot, depending on stack diameter, height, access difficulty, and building occupancy. A typical 3-4 story stack might cost $8,000-$15,000 to line. Traditional replacement of the same stack—including demolition, new pipe, reconstruction, and finishes—often costs $20,000-$40,000+. The total savings increase with building height since demolition and reconstruction costs multiply with each additional floor.
Yes, trenchless repair (specifically CIPP stack lining) is the preferred method for fixing vertical sewer stacks in multi-story buildings. It repairs leaks, seals cracks, stops corrosion, and restores structural integrity without demolition. The process works on stacks of any height and accommodates various pipe materials and diameters. It’s particularly effective for cast iron stacks in older buildings where traditional replacement would be prohibitively expensive and disruptive.
Don’t wait for catastrophic stack failure to force your hand. Proactive vertical stack lining protects your property, your tenants, and your investment. Whether you manage one building or an entire portfolio across Louisiana, Pelican Underground delivers proven trenchless solutions that work.
