Maritime, rivers, lakes

Do you supervise the creation or renovation of urban features such as protective dykes, crossings or pontoons? Or the construction marinas or military harbours? Are you in charge of the routine maintenance or extension of quays or similar structures in ports or urban settings? Or of the creation and management of technical structures – fuelling stations, tanks, cargo wharves, quay extensions, etc.? Do you ensure the correct maintenance of dams, waterways and their locks etc. or do you coordinate their construction?

Whether they are old or new, we are familiar with all these aquatic structures, with the stresses they undergo and the particular criteria involved in controlling them.

In the investigations phase as in the engineering phase, we mobilise our experts to provide you with appropriate, sustainable global solutions.

Your engineering consultancy partner

A dedicated project manager and a team of experts

Mobilisation of teams of experienced experts – investigations and engineering – concerning the maritime, river and lake activities field
Coordination of experts in different fields with all the actors on a project

We think solutions adapted to your needs

Knowledge of the stresses these structures are subjected to and mastery of specific techniques
Ability to propose specific dimensions adapted to the data specific to the aquatic environment and the structure concerned

We optimise the calendar

Recommendation of the period most conducive to conducting the investigations in the aquatic environment
Mastery of the performances of the investigations in aquatic environments
Mastery of the implementation schedule taking account of the degree of technicality of the surveys

We are in control of our interventions

Adaptation of the means to the context, specific accreditations (in particular for pontoons, and in compliance with the regulations)
Securing interventions on the worksite at every stage

Our mission: to be your expert partner on your project

Data collection using appropriate investigational means
Definition and optimisation of the geotechnical structures in light of all the constraints specific to the aquatic environment

Establishment of the layout of the longitudinal geological profiles and resistivity sections using non-destructive methods

Prevention and anticipation of natural or anthropogenic risks
Cliff face stability studies

Management and exploitation of the water system
Protection of groundwater
Instrumentation of piezometers (correlation between the level of the water against the quay and the thrust of the water inside the quays

Historical, documentary and environmental studies
Environmental diagnosis of the subsurface environment
If pollution confirmed, comprehensive support: management plan, assessment of the health risks, monitoring of decontamination work, regulatory certificates (ATTES)
