Underground construction means particularly environmentally friendly and fast implementation, which makes it ideal for connecting supply and disposal lines at the consumer's premises. Or for replacing old service connections when they reach their capacity limits or are damaged. It has a minimal impact on the environment and is also a real alternative to open construction in economic terms, thanks to its low cost and rapid, cost-saving implementation. Whether for water, electricity, heat, fibre optics or sewage, our versatile NODIG technology can be used to install or replace house service connections in any type of soil without digging trenches.
