Geofysiikan asiantuntija

GeoBlast Oy on suomalainen malminetsintään, geotekniikkaan sekä maa- ja pohjarakentamiseen geofysiikan palveluita tarjoava yritys. Toimintamme kattaa kenttätyöt, tulkinnat ja konsultoinnin avaimet käteen -periaatteella läpi hankkeiden koko elinkaaren.

We prioritize customer service, high quality solutions, respect of environment, and safety in all our activities. To reach our values we are committed to interaction and development with our clients and partners in all activities we are participating in.

Our Services

Malminetsintä

We offer full set of ore prospecting methods with our partners, but mostly we are concentrating on potential field methods like magnetics and gravity.

We offer also project management and consulting services.

Geotekniikka ja insinöörigeofysiikka

We have conducted a wide range of geotechnical projects including determination of soil and bedrock properties, road structure and pavement investigations, foundation studies of big structures like wind mills, buildings etc., lane investigations of highways, underground, tunnels etc. But also the object mapping like pipe, culvert, and wire detecting as well as the uncovering of hidden bodies like old buried gasoline tanks.

Moreover, we are also familiar with environmental projects and more exotic applications like archaeological tomb investigations and different kind of military applications. We have an expertise to the project management and consulting of this kind of projects.

One way or another, almost all our studies involve soil and subsoil investigations or the localization of underground structures or objects. Combining geophysical data with geotechnical data provides a comprehensive picture of the site.

Rakennustekniikka

We have been involved in many civil engineering projects as a partner applying geophysical methods. Projects have often been to detect targets inside man made structures like pipes or wires in concrete and to determine the properties of that kind of structures but also simple dimensions determent of structures.

We have put more attention to structure scanning we believe has a bright future ahead. It can be exploited in quality control as well as damage searching.

We respect environment and safety in all our activities.
