Triton-backed Unica, an independent provider of technical services, completed the acquisition of Gerco Brandpreventie, a company advising & installing systems to seal against fire & smoke, from Bolster Investment, a long-term investor specializing in minority interests. Financial terms were not disclosed. “The fire safety market is growing and more and more knowledge is required. It is therefore a logical step to join forces with Unica and further expand the range of services. I have always enjoyed working with Bolster. A down-to-earth party that has always supported me and actively guided the transformation of our company," Hans Nijssen, Gerco Brandpreventie General Director.
