Dam and landfill construction - a watertight case
WALO is a pioneer in the field of bituminous asphalt seals : our know-how is in demand worldwide for the construction and renovation of dams, reservoirs, pumped storage and equalizing reservoirs, as well as for the construction of shipping canals, artificial lakes and irrigation systems for agriculture.
