About us

Who we are and what we do

Our background

Site-Tech started in 2021 straight out of Aalborg University where proof of concept for the autonomous mortar removal machine was created during a group project on the topic. Since then both the technology and business have been growing, and we aim to be a reliable partner for building renovation companies and to be the technological leader in the field.


During the years, we have worked on almost 10 different building sites and removed all together over 700 m2 of mortar joints. Currently, we are working on the fourth generation of our autonomous robot for mortar removal with the aim of certification and serial production.

What we do

We aim to be known as one of the construction industry's most innovative companies, solving real problems for both the craftsman and customers. We increase productivity and reduce attrition on the construction site and among workers with the help of our innovative technical solutions. The core of our current business is robots performing autonomous mortar removal from brick walls.


We are establishing ourselves as the industry's most competitive contractor when it comes to mortar joint removal, in terms of all sustainability, price, quality, and time.

Quality and consistency

Our robot removes the horizontal joints in a single long stroke of a mill. It also takes into account the position and irregularities of each brick, which results in less scratching and generally nicer cut than when using hand tools.

Increased productivity

The machine can work from the time the building site opens until it closes. Therefore, it eliminates the need to rotate workers on this usually very demanding position. An operator can operate up to 4 machines at once. This results in more than 6 times the productivity for mortar removal by a single worker.

Quieter and cleaner

The noise burden on the staff and environment is reduced as the cutter is handled and guided by the robot. The removed mortar is extracted by a custom designed suction head for the milling machine which captures the dust and prevents its spread on the construction site.


Manual joint milling is very physically challenging, and craftsmen can typically only do it for 2-3 hours per day. Moreover, there is a high risk of wear and tear, and even nerve damage. We replace this job with the comfortable monitoring and operation of a fleet of robots through our graphical interface.
