Geobags are an effective geotechnical material used to protect coastlines.

Its characteristics include:

1. Strong resistance to seawater erosion: able to maintain stable performance in high salinity and strong wind and wave marine environments.

2. Good adaptability: able to adapt to the complex and varied terrain and water flow conditions along the coastline.

3. Eco friendly: It can provide habitat and breeding space for marine organisms, helping to maintain the balance of marine ecology.

In terms of coastline protection, it has important applications:

1. Wave prevention and energy dissipation: Reduce the impact of waves and minimize their erosion of the coastline.

2. Stabilize the beach: prevent the loss of the beach, maintain the shape and area of the beach.

3. Promote vegetation growth: provide a foundation for the rooting and growth of coastal vegetation, and enhance the natural protective ability of the coastline.
