Relining. Seamless repairs.

Repair and Renovation Without Breaking or Demolition

While many companies offer sewer relining for large-diameter pipes (315 mm and up), we specialize in smaller pipe diameters, from 40 mm to 300 mm. Within this niche, we’re proud to be the market leader in the Netherlands—and the first company fully certified for these dimensions according to German DiBt standards and IKT-tested.

Why Renovation Matters

The biggest advantage of sewer renovation is that we can restore entire sewer systems—or large sections—without breaking into your floors or walls. And outside the property, there’s little to no need for extensive digging, roadwork, or removing asphalt.

While it’s rarely necessary, we can even renovate up to 100 meters in one seamless section. The quality of our materials is so high that a relined sewer often lasts longer than the original pipe. This method works on virtually all common pipe materials, including PVC, HPPE, PP, clay (gres), Eternit, and cast iron—and bonds perfectly in every case.

Relining comes in two main forms, each suited for different problems:

When to Use Full Liner Renovation (CIPP)

For long stretches of damaged pipe
When replacement is needed but access is limited
When breaking floors or digging up streets is not an option; or simply undesirable
When it’s impossible to close roads or halt traffic

A seamless liner is inserted and cured inside the existing pipe—no demolition required.

When to Use Sectional Repairs (part-liners)

For short, localized repairs
When a crack or break is difficult/impossible to access externally
When it is undesirable to demolish a (new) bathroom or paving
When renovation must happen without halting operations
In hygienic environments like the dairy or food industry
When replacement is significantly more expensive

A localized solution without breaking, demolishing, or replacing the entire pipe.

Benefits of Relining

Little to no digging or demolition
Suitable for both horizontal and vertical pipework
Prevents root intrusion and soil infiltration
Seamless, smooth interior
No transitional connections
Rapid completion times
Up to 100 meters in one go

Renovating Main Sewer Connections (Uplifts)

We also offer renovation for main sewer connection points (opzetters) using our patented IROTS method. This is a specialized form of sectional repair, where a liner inflates inside the existing connection and hardens into a brand-new pipe within the old one—without needing to break open streets or shut down traffic.

Benefits of IROTS Uplift Renovation

No need to break open or close streets and thoroughfares
Fits nearly all types of main sewer connections
Prevents root intrusion and soil infiltration
Seamless, smooth interior
No transitional connections
Rapid completion times

As with all our renovation solutions, we can only offer a warranty when the cleaning is performed by us or a qualified professional. These methods require specialized cleaning to ensure long-term durability.
