The PORT EN BESSIN site has already undergone several developments since its creation in 1976. Most of the dissolution units have been upgraded as well as the bath manufacturing unit. The production areas represent 3400 m², the storage 1 000 m², the offices 400 m², the control laboratory and the R & D 150 m². The works currently underway (August 2018 to June 2019) will increase these surfaces by about 1,000 m². On the other hand, the Port-en-Bessin plant can also benefit from the support of its subsidiary PIERCAN USA, whose surfaces are about 3,400 m².
