Economic activity

During centuries, Hermalle-sous-Huy, situated in a fertile plain, lived agriculture mainly (notably production of sugar beet at the 19th and 20th centuries) and of livestock farming (cattle and horses), to which was added the industry.
In the second half of the 2nd century and in the beginning of the 3rd, one finds an establishment of tilemakers there - as attest it the excavations led from 1974 to 1976 in the Gerée country where were exhumed tiles carrying the NEHS, QVAS and GFPS marks.
At the 16th century, some villagers work in the mines of lead and alum of the left bank.
Since the 18th century, Hermalle-sous-Huy knows an important industrial activity by the extraction of the limestone. The exploitation of the surrounding subsoil continues again today by the SA Dumont-Wautier (Lhoist group).
The manufacture of zinc to the 20th century, the brickyard in the first half of the this century constitute other industrial poles.
The decline of the agricultural activity, freeing some soil, permits the creation of an industrial activity park at the end of the 20th century (www.spi.be). One finds some warehouses there, firms treating the lime, the raw materials of career, the concrete or the paintings, sawmill and joineries, an wrought ironwork, a warehouse of brewery...
