In order to secure high quality and safe tunnels, AMA Anläggning (a Swedish construction standard) now states that operators working with sprayed concrete, injection and bolting need to have a certification issued by Svenska Bergteknikföreningen. All major tunnel projects in Sweden now require the certification.

Edvirt® is accredited by Svenska Bergteknikföreningen to deliver the training and certification courses leading to the sprayed concrete, injection and bolting certifications.
