Freeing rivers so they can regain their natural flow

'We help restore environments where nature finds its balance'

A weir, a dam, a simple concrete slab across a river—and suddenly an entire ecosystem is cut in two. Fish can no longer pass through, sediment builds up, and the water warms and changes.

By removing artificial barriers, we restore the ecological continuity of waterways, thereby improving the functioning of aquatic ecosystems.

The removal of structures involves the partial or complete demolition of man-made structures such as dams, weirs, or levees that obstruct the natural flow of rivers.

Careful planning of the demolition

Temporary diversion of water flow to allow for dry-weather operations

Carrying out the leveling work

The replenishment of natural materials in the riverbed

The benefits

Restoring the free movement of aquatic species

Limiting water heating

Restoration of natural sediment transport

Restoring the diversity of aquatic flows and habitats

So, in practical terms, how does it work?

01

Assessment of the structure: nature, dimensions, accessibility, and environmental sensitivity

02

Consultation with stakeholders and obtaining permits

03

Development of the grading plan

04

Installation of cofferdams and diversion of water flow

05

Demolition work

06

Disposal/recycling and decontamination of materials as needed

07
