Fast interventions with no demolition required
CIPP rehabilitation of sewer stacks
CIPP rehabilitation of vertical stacks allows the restoration of structurally degraded pipes without opening walls across multiple floors.
In buildings, vertical stacks are critical elements — any failure can affect several apartments at the same time. When there are cracks, persistent leaks, or loss of structural integrity, structural liner rehabilitation provides an effective and long-lasting solution.
Common problems in vertical stacks
During CCTV inspections of sewer stacks, it is common to identify:
-
cracks along the pipe
-
open joints with leakage between floors
-
material loss in ageing pipes
-
defective connections between branches and the main stack
-
recurring infiltration affecting multiple units
In many cases, these issues are not localized — they develop over several meters, making point repairs insufficient.
How CIPP rehabilitation works
The process involves installing a fiberglass liner impregnated with resin inside the vertical pipe. The liner is then cured using UV/LED light, forming a continuous new pipe.
After curing, the result is a new structural pipe within the existing one, which:
-
restores structural strength
-
eliminates cracks and infiltration
-
reinforces weakened sections
-
improves internal flow conditions
This new structure functions independently while maintaining the hydraulic capacity of the system.
Durability and extended service life
CIPP rehabilitation of vertical stacks is not just a repair — it is a solution that extends the service life of the pipe by 40 to 50 years. Once cured, the fiberglass structural liner forms a new pipe with high mechanical and chemical resistance, capable of withstanding normal operating conditions over time.
When properly applied, this technology allows ageing systems to be restored and avoids full replacement, providing a durable, stable, and technically proven solution.
Advantages in buildings and condominiums
CIPP rehabilitation offers clear advantages in vertical stacks:
-
avoids demolition across multiple apartments
-
reduces total intervention time
-
minimizes disruption for residents
-
provides a single solution for issues along the entire stack
-
significantly reduces the impact of works
This method is especially suitable where traditional replacement would require opening walls in multiple units.
When to choose structural rehabilitation
CIPP is recommended when:
-
damage is present along several meters of the stack
-
the pipe shows structural deterioration
-
persistent infiltration cannot be resolved with localized repairs
-
a long-term, stable solution is required
In cases where only minor localized leaks exist, non-structural methods such as epoxy lining may be sufficient. However, when structural integrity is compromised, CIPP is the appropriate approach.
Preparation before installation
Before installing the liner, proper preparation of the pipe is essential, including:
-
detailed CCTV inspection
-
cleaning and descaling of the pipe
-
removal of intrusions or protruding connections
-
assessment of access conditions
This preparation is critical to ensure correct installation and long-term performance.
Application in different types of buildings
CIPP rehabilitation of vertical stacks can be applied in:
-
residential buildings
-
older condominiums
-
commercial properties
-
hotels and short-term rental units
As long as proper access is available, the intervention can be carried out in a controlled and efficient manner.
A structural solution for complex stack problems
When vertical stacks deteriorate over time, traditional replacement can be complex, time-consuming, and highly invasive. CIPP rehabilitation provides a technical solution by creating a new pipe inside the existing one, without the need for extensive works.
If your building is experiencing recurring leaks or issues in the vertical stack, we can carry out a technical assessment and recommend the most suitable solution.

Have another question? Request your diagnostic assessment.
Vertical stack rehabilitation is the process of restoring the vertical drainage pipes of a building — usually responsible for wastewater or rainwater flow — without having to replace the entire pipe. We use internal techniques such as epoxy resin coating or CIPP liners, which create a new watertight wall inside the existing pipe.
In most cases, no demolition or wall removal is needed. The intervention is carried out through existing access points (inspection boxes, sanitary outlets, etc.) using compact equipment that works from inside the pipe.
It depends on the number of floors and the condition of the pipe, but usually a full stack can be rehabilitated within one to two days, including cleaning, application, and final inspection. In occupied buildings, the work is carefully planned to minimize any interruption of water use.
Besides avoiding demolition, dust, and noise, rehabilitation with resin creates a smooth, watertight new inner surface that improves flow and prevents future leaks. It’s also faster and more cost-effective, while offering durability similar to a brand-new pipe.
Yes. Epoxy resin and CIPP systems are fully compatible with stoneware, cast iron, PVC, and concrete pipes, as long as the base structure is stable. During the initial inspection, we assess the condition of the pipe and recommend the most suitable method for each building.
