CPC Bautechnik AG Bern offers economically sound contractor solutions for special problems in building construction and civil engineering. We act as consultants prior to the tendering process or are called in to carry out pilot projects. We also specialize in concrete renovation and concrete milling.
In the field of sewer renovation, we offer new solutions thanks to the CPK dry weather channel made of epoxy.

CPC Bautechnik AG Bern, based in Studen, was founded in 1981 by Peter Lüthi, a graduate engineer ETH/SIA. The new company's fields of application, concrete drilling and milling, were soon expanded to include a wide range of renovation and other specialist work in building construction and civil engineering. In 1990, the cooperation with the company Stettler AG in Biel began. Christoph Loosli, a federally certified master builder, joined the company as managing director in 1998.
Today, Stettler AG Biel Studen owns 100% of the share capital. Important milestones in the company's history include the development of CPK dry weather channels, the reactivation of the concrete drilling and cutting department by renewing the inventory and the successful recertification according to ISO 9001 in April 2021.
CPC Bautechnik was also the lead partner of ARGE ARA Biel, which carried out the contract to renovate the Biel wastewater treatment plant.
