What is trenchless pipe rehabilitation?

Trenchless pipe rehabilitation is a method of repairing or renewing damaged pipelines from the inside, without excavation or breaking floors, walls, or surfaces. Techniques include brush coating, spray lining, and epoxy relining — all performed through existing access points.

What is the difference between spray lining and brush coating?

Spray lining applies an epoxy coating using a rotating spray head, covering the pipe interior evenly at high speed. Brush coating uses a rotating brush head to apply epoxy material layer by layer. Both are trenchless methods, but spray lining is faster for longer pipe sections, while brush coating is better suited for bends, junctions, and short sections.

What is the Nodig BSE epoxy coating?

Nodig BSE (Brush & Spray Epoxy) is a two-component epoxy coating system designed for pipe rehabilitation. It is available in two colours — one for each component — allowing operators to visually confirm complete mixing and even layer application. BSE is compatible with all Nodig ProLight and ProLight2 machines.

What pipe diameters can Nodig equipment rehabilitate?

Nodig equipment covers a wide range of pipe diameters. The ProLight and ProLight2 machines are designed for pipes from DN40 up to DN150 mm. The Pipe Boy industrial machine handles DN50 to DN300. High-speed chain cleaning machines (V8, V1, mini6) are available with accessories for various pipe sizes — please contact Nodig or check the product catalog for specific configurations.

When is trenchless pipe rehabilitation not suitable?

Trenchless rehabilitation methods such as brush coating and spray lining are not suitable for completely collapsed pipes, pipes with severe structural damage requiring mechanical reconstruction, or cases where pipe alignment has significantly shifted. In these situations, conventional excavation or pipe replacement may be required before any lining can be applied.

Where is Nodig equipment manufactured?

All Nodig machines are designed and manufactured in Croatia. Nodig d.o.o. has been developing pipe rehabilitation and cleaning equipment since 2012, operating under the brand philosophy 'Genius of Simplicity' — focusing on reliable, field-ready equipment with the best performance-to-cost ratio on the market.

Does Nodig offer training for their equipment?

Yes. Every Nodig machine purchase includes complete operator training at the Nodig Training Center. The training covers the full rehabilitation process — from pipe preparation and inspection to epoxy application and quality control. Ongoing technical support is also included after training.

Can I become a Nodig reseller or distributor?

Yes. Nodig actively seeks partners across Europe and globally. Authorized partners receive technical support, marketing materials, and preferential pricing. Training at the Nodig Training Center is available to all partners. To apply, visit the Partnership page on nodig.hr or contact Nodig directly.

How does high-speed chain cleaning work?

High-speed chain cleaning uses rotating chain heads driven by a machine (V8, V1, or mini6) to mechanically remove scale, deposits, roots, and hardened material from the interior of pipes. The process is highly effective for preparing pipes before epoxy lining or for restoring flow capacity without excavation. Different chain head configurations are available for various pipe conditions and diameters.

What is the typical application for Nodig pipe rehabilitation equipment?

Nodig equipment is used in residential buildings, commercial properties, industrial facilities, and municipal infrastructure. Typical applications include rehabilitating corroded or leaking drain pipes, restoring flow capacity in sewer lines, applying protective epoxy lining in potable water pipes, and performing preventive maintenance on aging pipeline systems — all without demolition or excavation.

What are spray lining and brush coating?

Spray lining and brush coating are trenchless pipe rehabilitation methods in which the inside of a pipe is coated with an epoxy lining to create a new protective layer, extend service life, and reduce the need for excavation.

Why do contractors choose these methods?

When floors, walls, or external surfaces should remain intact, these solutions make pipe rehabilitation faster, cleaner, and easier to manage. With proper preparation and controlled application, contractors can deliver reliable internal coating results with less disruption on site.

When is it used?

For aged, worn, corroded, or damaged pipes where rehabilitation is needed without major demolition work.

When is it not ideal?

For fully collapsed pipes, severe structural failures, or situations that first require major mechanical reconstruction.

Main advantage

Faster rehabilitation, less site mess, and better process control than traditional invasive repair work.

Typical applications

Residential buildings, commercial properties, service lines, and technical systems where minimal disruption matters.

What has to be done right?

Pipe preparation
Cleaning and preparing the pipe surface is essential for coating consistency and long-term performance.
Application control
Brush coating and spray lining both depend on stable material flow and precise process handling.
System selection
The right machine, head, hose, and material depend on pipe diameter, condition, and job type.

About Us

Once upon a time, back in 2012, we started out as a small team of “handymen” solving underground disasters of all kinds. If something needed saving below the surface – we were the ones crawling around to fix it. After seven years of working on sewer cleaning and rehabilitation, we realised one thing: we can build this better ourselves. So we did. That’s how Nodig – Genius of Simplicity – was born. And just to be clear – we’re not here to sell you machines that magically work on their own. We’re here to give you the machines, the knowledge, and the training so that YOU can do incredible things with our equipment.

Today, we proudly remain a very unserious company building extremely serious machines. Yes, we joke a lot, yes, humour is part of our DNA, and yes, we sometimes absolutely overdo it. But three things are always serious: solving real problems in the field, building machines that still work when everything else fails, and giving you solutions that make your life easier, not harder. And if you’d like us to become even less serious while producing even more serious products, there is a very simple strategy: JUST BUY MORE. Our products and solutions are designed to be very serious, very robust and very long‑lasting. We have a solution for almost everything. The only thing we still don’t have a solution for is human stupidity – there, we’re afraid, even engineering has its limits.

Our philosophy is simple: build the most efficient machine using the simplest possible solutions. We don’t promise miracles, but we do promise not to sell you junk. And in our long‑term plans, a portion of our revenue is destined to be “invested” in beer, child support, expensive watches, unnecessarily large cars and other completely unnecessary things – until we come up with something better. Welcome to Nodig – where serious technology comes wrapped in a dose of humour and a lot of engineering stubbornness.
