Back in his home country, Van Rysselberghe met Isabel Martínez, daughter of the Chilean engineer Valentín Martínez. The two married in Europe before moving to Chile in 1905. He took charge of regulatory plans for several towns around Valparaíso and Santiago before moving to Concepción. Here he worked as an engineer for the Railway Company, taking charge of the Concepción arsenal. After his retirement, he bought Lonco Valley, dedicating himself to quarry stones, wherewith he supplied the railways.
