Founded in 1898 by Corneille Karp-Kneip, the company is still a family business run by François, Christophe and Linda Thiry, the 4th and 5th generations of the founder. Karp-Kneip and its partners are present in France, Germany, Belgium and, of course, in Luxembourg. Through its partners, the company has succeeded over time in developing complementary business lines centred on roads, civil engineering, ecological construction and renovation, as well as gardening and forestry.
