Over 11-13 September, Stockholm will be host city to the 10th Nordic Grouting Symposium. The event is being organised by Svenska Bergteknikföreningen (SVB – the Swedish Rock Engineering Association).
Themes for the latest symposium are: concepts and design for grouting; grouting materials; requirements and verifications; grouting equipment; grouting of soilrock- concrete interfaces; contracts and compensation; and, case studies.
The venue is the Hilton Stockholm Slussen, in the centre of the capital, where the organisers have arranged rates for delegates.
PROGRAMME
Course & Technical Tours
The main symposium gathering is preceded, on 11 September, by a one-day grouting course – Practical Usage of Grouting Fundamentals. The course is being hosted at the Trafikverket’s (Swedish Transport Administration) project site at Lovö on the Stockholm Bypass.
Stockholm Bypass is also the focus of the symposium’s first technical tour, in the afternoon, at the site. The second technical tour – to the expanding underground metro – will take place the following day, on 12 September, after the first busy day of the symposium programme.
Technical Programme
Keynote speakers at the symposium are Håkan Stille, of Geokonsult Stille AB, and Knut Garshol, of K. Garshol Rock Engineering Ltd.
Stille is to speak in his morning keynote, after the Opening Ceremony, on the topic ‘Transformation of grouting from black magic to art of engineering’.
Following two technical sessions that first day of the symposium, the afternoon’s proceedings are to hear the keynote by Garshol on the topic ‘Challenges of grouting for groundwater control in hard rock tunnelling’.
Afterward, while some delegates can join in the technical workshop, others can opt for the metro site visit.
In total, the symposium has five technical sessions, arranged to the main themes of the event. Two technical sessions are to be held on the first day of the symposium (12 September), and three on the last day (13 September).
In the following summary list, the proposed grouting papers to be presented relate to tunnels only or general interest of grouting (the symposium has a few more papers planned for presentation but while technically of interest there are no tunnels involved, such as a geotechnical focus on foundations for a dam and, offshore, a floating terminal).
For reasons of space, only the name of the lead author (as provided by the organiser) is listed along with the title of the paper to be presented.
