A family business since 2000
Pekka Maukola started in district heating in the 1960s at the Helsinki utility, launched KWH Pipe's district heating pipe production in Vaasa in 1974 and led marketing for Raychem's Pipe Protection division in Belgium. The DualSeal patent came out of that period, the same product Kampek sells today.
Raychem wanted him as its distribution channel in Finland, and Kampek was founded in 2000. Since 2017 the company has been run by his son Petteri Maukola, with Mikko Partti in charge of the warehouse and deliveries in Tuusula.
You reach Petteri and Mikko directly by phone, no switchboard.
