Sealing of pipe joints and connections

In many cases of leaks and water infiltration, the issue is not the pipe itself, but the joints and connections between sections. Over time, these areas become vulnerable due to wear, slight structural movement, or poor installation.

Using internal epoxy lining, it is possible to seal these critical points without opening walls, floors, or replacing the pipe, restoring the watertightness of the system.

Why joints fail

Pipe joints are naturally the most sensitive points in any drainage system. Even when the pipe is in good condition, it is common to find:

• slightly open joints
• degraded sealing materials
• slow infiltration points
• deposits forming due to internal irregularities

During CCTV inspections, we often observe water trails, deposits, or flow marks, indicating leakage even when no visible crack is present.

How epoxy sealing works

The process involves applying epoxy resin internally, forming a continuous protective layer that:

• seals leaking joints
• covers micro-cracks
• stops infiltration points
• improves the internal surface of the pipe

The work is carried out from inside the pipe, following proper cleaning and preparation to ensure correct adhesion.

When this solution is suitable

Epoxy joint sealing is particularly effective in cases such as:

• unexplained dampness on walls or ceilings
• leaks in vertical stacks or branches without visible breakage
• open joints in PVC or clay pipes
• aging connections showing deterioration
• situations where invasive works should be avoided

In many cases, this approach allows for a direct and controlled repair without full pipe replacement.

Limitations of the solution

It is important to clarify that epoxy lining:

• does not correct pipe deformation
• does not fix misalignment or structural collapse
• is not a structural rehabilitation method

Its purpose is to restore watertightness and protect the pipe internally, being highly effective when used in the right conditions.

Inspection before intervention

Before any application, we always recommend a CCTV pipe inspection, which allows us to:

• accurately locate leaking joints
• assess the overall condition of the pipe
• confirm if epoxy is the appropriate solution

This ensures a proper technical decision and avoids unnecessary interventions.

A precise solution for localized issues

Joint and connection sealing is one of the most common interventions in drainage systems. When properly applied, it resolves persistent leaks effectively, with minimal disruption and no need for invasive works.
