In addition, Ingetec brings in-depth knowledge of the specificities of the Indian Ocean market, including regulatory frameworks, humid tropical zones, seismic activity, construction materials, and land-use pressure.

Our local office relies on a national network of 8 offices and more than 80 professionals to deliver pragmatic solutions to the environmental challenges faced by local authorities.

All our experts share the same values of inclusivity, proximity, and commitment.

How Ingetec Océan Indien addresses local challenges

Building resilient cities in tropical environments

In the Indian Ocean, each territory has its own specific characteristics.
Yet, several major challenges are shared: the urgency of rapid demographic growth, uncontrolled urban sprawl that weakens natural resources.

Cities face multiple challenges: building in constrained spaces, on highly diverse terrains with multiple natural hazards; managing waste; creating inclusive cities; rationalizing the use of natural resources; protecting natural heritage and biodiversity.

Ingetec Océan Indien integrates a degree of innovation into every project to make everyday life easier for all.

Reusing and repurposing materials in island contexts

The vast majority of construction materials are imported, creating a significant price gap in raw materials compared with mainland France. Our systemic approach, based on the principle of eco-management, aims to rethink the material supply chain to reduce resource consumption throughout the life cycle and protect ecosystems.

At the scale of your project, we promote giving resources a new life by:

Making use of existing materials
Using locally sourced materials, a way to generate economic value
Recycling waste directly on site, transforming products
Recycling off site — despite the limited number of construction waste management facilities

Protecting coastlines and coral waters

Coastal management is a key issue for most municipalities in the Indian Ocean islands and represents a cross-cutting challenge that requires balancing:

The protection of coastal ecosystems and limiting the pressures of urban development
The development of integrated coastal and marine management, taking into account the watershed–coastal zone continuum

Finally, coral reefs, which play a pivotal role in restoring and preserving coastal water quality, host a rich biodiversity that contributes to coastal protection.

Sustainable road infrastructures to meet island challenges

In Mayotte and Réunion, road projects must address complex challenges: demanding geographical and climatic conditions (erosion, steep terrain, tropical rainfall) combined with strong demographic growth, which increases accessibility needs. The insularity of these territories adds further constraints, with limited space and high costs for materials and equipment.

The predominance of car use leads to congestion and pollution, calling for adapted solutions to secure roads and reduce their environmental impact.

At Ingetec, we provide practical responses to these challenges through our studies of construction in complex areas and the design of sustainable solutions for safer and more resilient roads. Discover our expertise on this page.
