The Groupe Sica ATLANTIQUE was born at the end of the 50s from the strong will of a few pioneers in the grain export sector. Around 80 grain operators decided to gather their strengths to build the first port silo dedicated to export.

Louis Tercinier, Président of the Board

Since then we always have nurtured our commitment to the regional agricultural sector; our shareholders and board members are all local grain market actors.
Our vocation is to design and implement innovative, integrated, global solutions to optimise and massify logistics flows for players in the agricultural and agro-industrial sectors, who represent our core businesses. We are their main port logistic operator. We also develop services for other sectors working towards our strategic objectives.

Since 1992, we have developed and organised our activities into 6 complementary divisions.
We have become the leading port operator in La Rochelle-Pallice.
