Localized repairs with CIPP packers

Fix the problem — not the whole pipe

Not every pipe needs full rehabilitation.

In many cases, the issue is local: an open joint, a crack, a defective connection. It makes little sense to intervene over several meters of pipe because of a single defect.

This is where localized repairs with packers come in.

What a packer is and how it works

A packer is a point repair system based on a resin-impregnated sleeve applied exactly at the damaged section of the pipe.

The process is simple but highly effective:

• the sleeve is wrapped around a packer (inflatable bladder)

• the unit is positioned at the exact defect location

• the packer is inflated, pressing the resin against the pipe wall

• after curing, the packer is removed

This leaves behind a solid, watertight and reinforced section inside the pipe. :contentReference[oaicite:1]{index=1}

When packers are the right solution

This method is ideal when the issue is localized, such as:

• small cracks

• open joints

• minor leaks

• defective connections

Instead of repairing the entire pipe, only the affected area is treated — with minimal disruption.

Real advantages in practice

Packer repairs allow:

• no demolition or excavation

• fast interventions (often same day)

• lower cost compared to full rehabilitation

• precise and targeted repair

This is especially useful in residential buildings and areas with difficult access.

But it’s not for every situation

Important: packers are a local solution, not a full rehabilitation method.

If the pipe shows deterioration over several meters, settlement or multiple defects, this approach may not be enough.

In those cases, better options include:

• continuous epoxy lining

• or full CIPP structural lining

In short, packers fix a point — not an entire system.

Preparation before repair

Before applying the packer, it’s essential to:

• locate the defect with CCTV inspection

• clean the pipe

• remove debris or obstacles

Without proper preparation, adhesion and durability may be compromised.

Precision instead of over-intervention

At REVIPOX, we adapt the solution to the real problem.

If it’s localized, we repair locally. If it’s structural, we recommend a different approach.
