Beaches and Dunes Restoration.

Nature-Based Coastal Protection in Mauritius.

Sustainable engineering solutions to:

Restore Eroded Shorelines

Stabilise Beaches

Protect Coastal Sand Dunes

OceanVolts specialises in soft engineering approaches for the recovery and long-term resilience of degraded beaches and dunes.

Through a blend of

• Scientific design
• Ecological rehabilitation
• Long term maintenance

We restore natural coastal dunes that reduce erosion, enhance biodiversity, and support sustainable coastal protection.

Tailor Made and Site Specific Solutions

Adaptive Coastal Restoration for Every Site and Budget

At OceanVolts, we recognise that no two coastlines are alike. Each beach in Mauritius — from the exposed dunes of Bel Ombre to the calm lagoons of Grand Port — experiences its own combination of wave action, sediment movement, and human impact.

That’s why our beach and dune restoration solutions are tailor-made and site-specific, designed to match the physical characteristics and financial capabilities of each client.

Our approach begins with a detailed site assessment covering parameters such as:

• Extent of erosion
• Length of beach frontage
• Sand volume requirements,
• Available restoration & long-term maintenance budget.

This ensures that our solutions remain flexible, scalable, and cost-effective, whether for small private properties or large coastal developments.

By combining coastal science with practical experience, we deliver:

• Technically sound
• Sustainable
• Financially adaptable restoration programmes.

Our goal is to help clients protect their coastlines while enhancing natural resilience, biodiversity, and long-term value.

Key Advantages:

Custom solutions based on site-specific data and client budget.

Flexible restoration scope — from small-scale dune rehabilitation to full beach re-profiling.

Designed for long-term adaptability, ensuring lasting shoreline stability.

Balances economic feasibility with environmental sustainability and aesthetic value.

Why Restore Beaches and Dunes?

Understanding Coastal Erosion in Mauritius

Mauritius’ sandy beaches are under growing pressure from rising sea levels, wave energy concentration, and unsustainable coastal development.

These forces accelerate shoreline retreat, loss of recreational beaches, and the collapse of dune ecosystems.

Restoring these natural defences is crucial to protect assets, habitats, and local properties while maintaining the island’s coastal beauty.

Key Facts:

• Over 80% of sandy beaches in Mauritius show signs of erosion or sediment depletion.
• Coastal dunes can absorb up to 70% of incoming wave energy during storm events.
• Healthy dunes and beaches support a diverse coastal flora and fauna as well as shoreline stability.

Our Soft Engineering Approach

Engineering with Nature

OceanVolts’ Restoration Methodology

At OceanVolts, we apply science-driven and low-impact coastal engineering techniques tailored to site-specific conditions.

Our interventions prioritise natural sediment dynamics, vegetation stabilisation, and client participation for sustainable outcomes.

1. Beach Nourishment and Sediment Rebalancing
We use locally sourced sand and environmentally compatible materials to rebuild eroded beaches, restoring their original width and elevation. Numerical modelling ensures the design maintains equilibrium with wave and current patterns.

2. Dune Reconstruction and Stabilisation
Degraded dunes are reshaped using compatible sediments, reinforced with biodegradable geotextiles, and stabilised through native vegetation planting such as:

• Scaevola taccada,
• Ipomoea pes-caprae
• Pandanus species.

3. Vegetation-Based Protection
Plant root networks increase dune cohesion, reduce wind erosion, and trap sediment naturally. Our established coastal nurseries supply native species, ensuring long-term care of vegetation introduced to achieve a self-sustaining vegetation cover.

4. Bioengineering and Sand Fencing
We deploy coir logs, brushwood fences, and bamboo sand traps to reduce wind speed, accumulate sand, and promote dune formation while maintaining a natural aesthetic.

5. Monitoring and Maintenance
Post-restoration monitoring using RTK GPS profiling, and photo documentation ensures adaptive management and performance validation.

Environmental and Socioeconomic Benefits

From Eroded Coasts to Resilient Shores

Our projects deliver measurable improvements in both environmental integrity and community resilience. By integrating engineering, ecology, and education, we create multi-benefit coastal systems.

Ecosystem Restoration: Revives dune vegetation and coastal habitats.

Tourism Revitalisation: Restored beaches attract visitors and enhance aesthetics.

Community Protection: Safeguards coastal villages and resorts from storm surges.

Scientific Innovation: Data-driven design supported by OceanVolts’ modelling and monitoring capabilities.

Carbon Sequestration: Native dune plants contribute to local blue carbon storage.
