Normet’s new battery electric sprayer, the Spraymec 8100 VC SmartDrive performing remarkably inside the Finnish bedrock

The Blominmäki project is one of the biggest underground civil engineering construction projects up to date in Finland. It aims to construct a new wastewater treatment plant to serve more than 400 000 people and five cities and replace the old treatment plant in Suomenoja. The excavation project consists of circa 1 000 000 cubic meter caverns for water treatment processes, and 19 kilometers of water tunnels between the seacoast and the new plant.

Normet’s battery electric sprayer, the Spraymec 8100 VC SmartDrive, was taking part in spraying the permanent sprayed concrete lining at one of the Blominmäki sites. The sprayer proved its worth in providing efficient, silent, and clean application process with low operating costs.

“Air quality is extremely important when working underground” says Pasi Hartikainen, who has been operating the Spraymec 8100 SmartDrive in Blominmäki. “It is one of the main benefits of having battery electric equipment that there are no diesel emissions”, Pasi describes his impressions on working with the new sprayer.

In addition to battery electric drive, the new flag ship sprayer is equipped with automated boom control system SmartSpray, and concrete layer thickness optimization system SmartScan.

“We have very demanding clients and they will check through every layer of sprayed concrete”, says Mikko Piirainen, Construction Manager for tunnelling contractor Kalliorakennus-Yhtiöt Oy, who’s sprayer fleet consists solely of Normet offering. “In the future, SmartScan will have a remarkable role in terms of providing best quality. Using SmartScan ensures the layer thickness is sufficient, and that there is no need to come back and spray again.”, Mikko adds.

Normets battery electric SmartDrive technology is available widely throughout Normet’s equipment offering.
