In the post-war period, Maurice’s eldest son, Ernest Decolvenaere, helped reconstruct the saw mill. An old crosscut saw was installed at the parental house in Gentbrugge, which was used to saw up poplars. In order to specialise, the emphasis was initially placed on Norwegian wood. One of the early customers, one of the largest frame factories in Belgium, gave the company the impetus to think bigger. A correct approach to the timber trade gradually also earned the confidence of the whole sector. Larger quantities could be purchased and converted. This provided the impetus for the company to start conducting its own exploration, commercial exploitation and importing activities.
