About us

Our story

Rock Physics Finland Ltd was founded in 2018 by two experienced geophysicists. We specialise in the physical properties of rocks, rock mass and building materials, specifically for the needs of exploration, mining and rock construction. Our laboratory is in Kerava, Finland. We are a Reliable PartnerĀ®.

Risto Kiuru

(M.Sc., BBA)

Risto is a senior geophysicist (M.Sc.) and safety, security and risk management (BBA) specialist focusing on rock physics and currently finishing a doctoral degree (D.Sc.Tech.) in rock mechanics while actively working as a consultant for various civil engineering and mining projects. He has more than 10 years of experience in rock physics and rock mechanics laboratory testing, borehole geophysics and field geophysics related to the final disposal of spent nuclear fuel, exploration, mining, and rock construction.


He serves as a member in the ISRM Commission on Testing Methods, and in the ISRM Commission on Radioactive Waste Disposal. In 2022, he was selected as a national expert in ISO/TC 182, and as the national delegate for ISO/TC 182/WG 10 "Laboratory testing of rocks".

Randima Seemantha Arachchi

(B.Sc.)

Randima is a geologist (B.Sc.) currently working on a master's degree in geophysics (M.Sc.) at the University of Helsinki. He has several years of experience on a variety of geophysical methods, both in the field, as well as in the lab, 3D modelling and integrated geophysical/geological interpretation.
