Ca Mau (VNA) - The southernmost province of Ca Mau is using pre-fabricated barriers made of non-metallic reinforced concrete to prevent landslides and coastal erosion.

Vice Chairman of the provincial People’s Committee Le Van Su said plastic and spun concrete had previously been used but the cost was too high, about 30 billion VND (1.29 million USD) per km.

To prevent landslides on 2.1km of seaside in Rach Goc commune, the province is using non-metallic reinforced concrete made of glass-fibre reinforced polymer, polypropylene fibres, polyester fibres and other types of non-metallic fibres.

To Quoc Nam, Deputy Director of the Department of Agriculture and Rural Development, said the fibres are waterproof and non-corrosixe.

The holes in the embankment walls also bring silt and sediment for the province’s protection forest.

The Ba Ria-Vung Tau Sewerage and Development Ltd Company, the main contractor of the project, said the pre-fabricated materials were solving problems caused by weather and hydrology, and were easy to maintain.

The total investment of the new materials for the project is 37 billion VND (1.59 million USD), much less than plastic and spun concrete.

The province aims to complete the embankments as soon as possible to ensure safety for residents in the commune.

Ca Mau province has the longest coastline (254 kilometres) in the Mekong Delta. About 105km are prone to landslides.-VNA
