Spray Coating – Internal Pipe Rehabilitation from the Market Leader – Without Excavation Work
This is precisely what the Spray Coating method achieves. Infravadis deploys this proven technology for trenchless internal pipe rehabilitation nationwide: completed in just a few hours, cost-effectively, and providing demonstrably durable protection for your piping system.
Spray Coating is a modern method for internal pipe rehabilitation, where liquid polyester resin is sprayed from the inside into the damaged pipe. The material dries in layers, automatically forming a new, completely intact pipe within the old one – entirely without the need for excavation work on walls, ceilings, or floors.
The result is a seamless internal coating that permanently protects the piping system against corrosion, cracking, and leaks, while simultaneously preserving the full flow capacity of the pipeline.
The Spray Coating method follows a clearly defined, proven process – from initial inspection to final approval. Depending on the application area – determined by CCTV inspection – we deploy the optimal coating system.
Prior to rehabilitation, the affected piping system is thoroughly cleaned and fully inspected with a camera. Deposits, residues, and loose wall sections are precisely removed.
The cleaned pipe is dried to ensure optimal adhesion of the polyester resin to the inner wall and to allow for a uniform layer build-up.
A specially developed rotating head distributes the liquid polyester resin uniformly and seamlessly along the entire inner pipe wall. This device is capable of navigating complex pipe configurations, 90° branches, and hard-to-reach areas – covering up to 33 meters in a single pass.
The resin cures in layers, forming a smooth, stable new inner wall. Within a few hours, the piping system is fully operational again. Learn more

Compared to traditional rehabilitation methods, Spray Coating offers significant advantages – particularly in sensitive environments where operational interruptions and construction noise are intolerable – further enhanced by professional diagnostics.
While conventional pipe renewals can take days or weeks, the rehabilitated pipe system, utilizing the Spray Coating method, is fully operational again within just a few hours.
The cured polyester resin provides long-term protection for the pipe system against corrosion, re-cracking, and leaks. Further leaks at the repaired site are impossible.
As no walls, floors, or ceilings need to be opened, ongoing operations remain completely undisturbed. Tenants, patients, and employees are not affected.
Without the need for demolition, drywall, painting, and material disposal, Spray Coating is considerably more cost-effective than traditional pipe renewal when considering the total cost.

All essential information concerning innovative pipe coating and complementary services.
A professionally applied spray coating is designed to last for several decades. The polyester resin used is corrosion-resistant, dimensionally stable, and resistant to typical wastewater contaminants. One of our unique selling points is a long-term test conducted by an independent engineering firm. This test certifies that our coating has a service life of over 50 years.
The method can be applied to pipes with an internal diameter of DN 40 mm, typically up to DN 200 mm in building applications. For larger nominal diameters, supplementary rehabilitation methods are available.
Depending on the length and condition of the affected section, the application typically takes only a few hours. Following the curing period, the pipe system is immediately ready for operation.
