Fast interventions with no demolition required
Epoxy lining of wastewater stacks
Epoxy lining allows the rehabilitation of vertical drainage stacks without opening walls across multiple floors.
In reality, most stacks don’t fail suddenly. What happens is gradual deterioration: joints losing tightness, small cracks, ageing connections. Over time, this leads to leaks, odours or recurring issues between floors.
This is where internal epoxy lining makes sense — not as a patch, but as a way to restore sealing along the entire pipe section.
Most common issues in stacks
From our inspections, we often find:
- leaking joints
- fine cracks along the pipe
- defective branch connections
- general ageing of old materials (PVC, cast iron, clay)
- leaks between floors with unclear origin
These are typically distributed problems, not isolated failures.
How epoxy lining works
The process always starts with proper preparation:
- CCTV inspection to identify defects
- technical cleaning of the pipe
- surface preparation
- controlled epoxy application
After application, a continuous internal coating is formed, sealing joints, cracks and small irregularities while improving flow conditions.
When this solution is suitable
- the pipe still has structural continuity
- there are leaks or loss of sealing
- deterioration is spread along several meters
- demolition across multiple apartments should be avoided
This is not a structural repair. In cases of collapse or significant deformation, other solutions are required.
Advantages for buildings and condominiums
- no wall demolition across floors
- faster intervention
- minimal disruption for residents
- multiple defects resolved in one operation
- extended lifespan of the existing pipe
This approach is especially useful in occupied buildings where full replacement would be complex and disruptive.
Epoxy or replacement? It depends on the real condition
In many cases, full replacement is proposed without proper diagnosis.
When the pipe is still structurally stable, epoxy lining offers a much less invasive solution. But the decision must be based on CCTV inspection and technical evaluation.
A practical solution for stack leaks
Epoxy lining is not suitable for every situation, but in the right conditions it provides an effective way to solve leaks and general deterioration without heavy works.
If your building has recurring issues, the first step is always to understand what is happening inside the pipe.
Frequently Asked Questions
Common questions about our process
At REVIPOX, we’ve gathered the most common questions about our epoxy pipe rehabilitation method.
Here you’ll find clear answers about how it works, how long it takes, and why it’s the most durable no-dig solution available.
Have another question? Request your diagnostic assessment.No. Epoxy lining is not a full structural replacement. It is an internal rehabilitation method that restores sealing and improves performance. It works well when the pipe still has structural continuity, but not in cases of collapse or major deformation.
In most cases, yes. The work is carried out through existing access points, avoiding demolition across floors. However, each situation must be evaluated — sometimes limited access points are needed.
When properly applied and prepared, epoxy lining can extend the life of the stack for many years. The actual durability depends on the original condition of the pipe and usage conditions.
The only reliable way is through CCTV inspection. This allows a proper assessment of whether the pipe is suitable for lining or requires a different solution.
