Diamond Drilling
Diamond Sawing
Since 1978




Rakennustapsa Oy was founded in year 1978, company specialized in diamond sawing. It was founded by master builder Tapio Soramo with his friend Tapio Hynynen. The friends had started the business in 1974. Already in those days came along work manager Osmo Lunkka,  whom has moved to a well deserved retirement from our company. At first, line of business was mining, civil engineering and industrial repairs and modifications, which always faced concrete and steel. So Tapio's founded Rakennustapsa Oy:n and begun to become familiar with a new work method, alias diamond sawing, because diamond edges would achieve clean cut through in hard materials, quickly and cheaply. Because in Finland there was no good tools accessible at the time, so they went to Sweden to get education as well as tools. Rakennustapsa Oy's Erkki Viitasalo was later designing wall sawing based on american machines.  We still have in our services old troupers, from which oldest employee has lasted for 25 years in the service and so diamond work knowledge and the skill has been able to pass on the younger generation.

Later in year 1979 Tapio Hynynen resigned from business and Tapio Soramo continued alone as a diamond sawing pioneer.

Main business became diamond sawing works around year 1984.
