Biological treatment

vign bacterie

100% biological boost

 

    DESIGNED FOR
Selected microorganisms brought into the water helping it to rebalance. They contribute to control the volume of organic sediment, algal blooms, and odors.  

• algal blooms
• decreasing sediments

Traitement Oxygénateur

O2

Un coup de de fouet pour les écosystèmes asphyxiés.

    INDICATIONS
Les granules d’oxygène libèrent immédiatement dans l’eau de l’oxygène dissous au niveau des sédiments. Ce traitement favorise la dégradation de la matière organique à l’origine des nutriments bio-disponibles. Il est possible de réaliser ce traitement dans les zones de baignades. Ces granules ne laissent aucun résidu toxique dans l’environnement.  

• limitation des odeurs
• réduction des vases

• mortalité piscicole

Waterproofing

geosyth

Designing and waterproofing artificial waterbodies using geosynthetic materials.

 

    DESIGNED FOR

ASQUAL certified.

We repair damaged membranes under and out of water using unique processes.

 

• artificial ponds
• storage of drinking water
• reservoir

Waterweed cutting

vign faucardage

For a quick result on invasive aquatic plants

 

    DESIGNED FOR

Intervention consisting in cutting aquatic plants with a waterweed cutting boat.

 

Aquatic plants are cut and brought to the bank

 

• invasive aquatic plants
• water weed, water lily
• swiming ground restoration

Dredging

vign curage

A vital rejuvenation

 

    DESIGNED FOR

Extraction of sediments that eliminates the sediment's layer and creates a new environment.

Extraction by divers limits the resuspension.

 

• silted up waterbodies
• algal blooms, cyanobacteria
• polluted sediments
• draught restoration
• swiming grounds

Vegetated Island

ilvegetalisee

Healing with plants

 

    DESIGNED FOR
Floating support with plants that filters and captures the excess of nutrients. The effect combines with the bacteria present on the roots. The island also has a shelter function to aquatic fauna.  

• decorative waterbodies
• struggle against algal blooms, invasive plants
• struggle against eutrophication
• fishing grounds
• biological treatment

Filtering marsh

vign marais

To foster biodiversity

 

    DESIGNED FOR

Area planted with species of "reeds" that holds the water suspension elements and absorbs the nutrients.

 

Area rich in fauna and flora with high aesthetic asset.

 

• runoff from catching area
• decorative waterbodies
• swiming grounds
• invasive aquatic plants
• eutrophication
• fostering biodiversity

Underwater works and assesment

vign barrage

Hydraulic structures and works of engineering

    DESIGNED FOR
Our specialized divers realize assessment and works on hydraulic structures and on works of engineering. Assessment : underwater recognition, ROV (Remoted Operated Véhicle) inspection, assessment of civil engineering (radar)... What we can do under water : repair, sawing, core drilling, concreting, repointing...  

• degraded works of engineering
• dams
• coffer dams
