COMPANY

Founded in 1987, Karanttia Oy Perusturva was originally a nationwide marketing company specialised in civil defence. In addition to the company’s main product, the prefabricated civil defence shelter, we offer full-concrete modular bathrooms. Both of these product assemblies are manufactured by the family company Rakennusbetoni- ja elementti Oy in Hollola, which has served as the stable and reliable co-operation partner of Karanttia from the very beginning. Karanttia Oy Perusturva is owned by the company’s founder Antti Kairinen and his children, who are also responsible for the company’s operations. From the outset, Karanttia’s operations have been based on delivery of carefree, prefabricated complete solutions for developers in keeping with the turnkey principle.
