Mincon Spiral Flush Leveraged for Crown Bridges Light Rail Project in Helsinki, Finland 

The Crown Bridges Light Rail (Kruunusillat) project is one of the biggest infrastructure projects in Finland in recent years. Construction started in 2021 and Mincon’s drilling expertise has played a significant role.
With the foundations of the bridges drilled right at the shore banks using the DTH method, it is important that air flow is controlled.
Our patented Spiral Flush technology prevents the air from escaping into the soil, thus making the drilling safer in complex ground conditions, like seashores in this case.
This was well observed by the constructor company, YIT, which compared Mincon’s Spiral Flush ring bit system with a competing wing bit alternative without air control.
