Tunnel Infrastructure

Autonomous drainage maintenance.


The first autonomous system for tunnel drainage maintenance

DrainBot is the first autonomous system developed for the main­tenance of tunnel drainage. Instead of the dominant water jetting technology, we apply intelligent robots to allow for removal and preventative main­tenance of the drainage pipes. This allows us to maintain tunnel drainage remotely and without any main­tenance-related tunnel locking times.


Enviromentally Sustainable

Other solutions use lots of water and heavy machinery powered by fossil fuels. DrainBot uses only the resources within the drainage system and thereby reduces both costs and environmental footprint of the maintenance for our customers. With reduced CO2 emissions and drastically reduced water consumption, our technology is the most environmentally sustainable solution on the market.

As one of the most prestigious and used road tunnels in all of Austria, the Gleinalm tunnel needs to be in operation as often as possible.

Foundations of our innovation

With the ongoing rapid pace of digitalisation of the infrastructure sector, DrainBot has decided to focus on not just the introduction of novel technologies, but also sustainability aspects of infrastructure operations, particularly tunnels. Our outstanding team with many decades of experience in product development and new technologies follows the vision of more efficient and sustainable usage of infra­structure, which is the core of our products and services.

DrainBot GmbH was founded in Graz in 2019. Our company’s mission is to create a better, more efficient, sustainable and innovative solutions for main­taining tunnel drainage all over the world. Together with international experts from our advisory board and leading professionals with decades of experience in the fields of engineering, innovation, tunnel maintenance and machine learning, we ensure that our products manufactured in Austria are of high quality and that tunnel operators in various regions and sectors are looked after.


We stand for


Our fully automated robotic system is the most efficient and most suitable solution for drainage maintenance in tunnels used for both railway and road transportation.


DrainBot is the only techno­logy on the market that uses only the resources within the drainage system thereby re­ducing the environmental footprint of tunnels.


The fully autonomous and robotic system uses a com­bination of several novel patented technologies and is able to communicate with us remotely at any time.


Our innovative reduces the demand for resources and costs of drainage main­tenance significantly making tunnels more efficient and sustainable.
