Trenchless construction

To avoid digging trenches, Eurovia calls on the expertise of its subsidiary, Valentin, which uses innovative technologies such as microtunnelling in the construction of new subsurface networks.

Different techniques are employed:

• To upgrade networks: cured-in-place pipe

• For maintenance and repair: reaming and grouting

Trenchless construction techniques can be used to create subsurface networks and to install pipelines in optimal conditions.

Repairs and upgrades to underground networks that do not permit human entry help to prevent or eliminate pipeline erosion and ensure infrastructure sustainability by restoring its original resistance and sealing strength.
