We provide comprehensive support throughout every phase of your civil engineering rehabilitation projects, ensuring a structured and efficient approach from initial planning to on‑site delivery. Our teams assist in defining a clear and realistic intervention strategy, tailored to the technical condition of the structure and the operational constraints of the site.
Our involvement includes the development of appropriate technical solutions for repair or refurbishment, adapted to the identified pathologies and performance objectives. We also support clients during the contractor selection process by contributing technical expertise to tender reviews and contract awards. Throughout the execution phase, we oversee the works to ensure quality, safety, compliance and adherence to project timelines.
Similarly, for civil and structural renovation projects, we accompany asset owners at each key milestone. This includes establishing detailed work schedules, designing robust repair or strengthening solutions, supporting procurement and contract allocation, and supervising construction activities on site. This end‑to‑end support enables secure, controlled and sustainable renovation of existing assets.
Our expertise operates from defining requirements to accepting works

Reinforced and prestressed concrete bridges
Recognised expertise in concrete engineering structures
We draw on our various areas of expertise to put our experience at the service of your concrete structure projects. Sixense is a leading company in the maintenance of reinforced and prestressed concrete structures.
If you are dealing with material deterioration, structural load-bearing defects, or durability issues related to prestressing cables, our experts will provide the most suitable technical solutions.
Steel bridges
We take into account the specific characteristics of steel structures
Whether we are working on old riveted structures or more modern bridges, we draw on our extensive experience in maintaining and restoring steel structures for structural repairs and the refurbishment of corrosion protection coatings.
Our Painting and Special Coatings division employs ACQPA-FROSIO inspectors who provide technical excellence in project specifications and can control the application of coatings directly on construction sites.
Masonry bridges
A heritage requiring specific expertise
To intervene in the most appropriate manner possible, with respect for heritage, our teams have extensive knowledge of professional recommendations and the different types of structures.
This expertise enables us to help you solve all kinds of problems that can affect these bridges, such as issues with the bearing capacity of supports, waterproofing defects, joint separation, vault decompression and strip detachment.
Metallic conducts
A range of proven repair solutions
Sixense can design and offer a wide variety of metallic conduct repair techniques, including adding a connected base plate, tubing, lining solutions (resin, PRV or HDPE), and reinforcement with shotcrete or formwork.
Our teams are aware of the hydraulic and environmental issues (e.g. fauna and flora) that must be considered from the design stage of projects.
We specialise in civil engineering and building
Water civil engineering
We offer a solution tailored to the specific characteristics of water storage and treatment facilities
Thanks to our extensive experience, we understand the unique requirements of civil engineering structures for water, including operating and distribution needs, waterproofing, special coatings and handling aggressive effluents.
We work on reservoirs, water towers, wastewater treatment plants, and drinking water treatment plants.
Industry
The process at the heart of the project challenges
Beyond the technical challenges, renovation projects in industrial environments must consider key operational requirements when planning and organising the work.
We work closely with the project owner during the design stage to ensure that the work can be carried out with minimal impact on the operation of the facilities.
Housing and the tertiary sector
We preserve the functionality and sustainability of buildings
We address all types of issues relating to the waterproofing or structure of buildings whenever the comfort or durability is compromised.
Some of our work is carried out as part of claims settlements, in support of the experts.
Car parks
Take into account the specific characteristics of car parks
These facilities present a number of challenges, including heavy loads, impact resistance of structural elements, fire resistance, operation and special coatings.
Our teams are able to handle all of these issues.
Public facilities
Large-scale buildings present significant challenges related to public access
Sixense works on numerous public facilities, such as stadiums, swimming pools, theaters, and museums, with the aim of restoring or improving operating conditions in terms of both comfort and safety.
