The embankment was almost breached during a massive flooding in July last year and local residents had to use bags of sand to strengthen it. In 2017, it was breached during heavy rain, inundating a commune and isolating thousands of residents for many days.

For the reinforced section, workers have dug one meter deeper from the current surface of the embankment to build the foundation. The project is built using the prestressed concrete method, in which concrete is substantially prestressed during its fabrication in a manner that strengthens it against tensile forces.

A reinforced concrete framework of two meters high is set up along the embankment. The surface of the bank has been expanded twice.

Hanoi is looking complete this project ahead of the annual flooding season that usually starts in September, and workers have had to speed up their work. They start early in the morning to avoid the summer heat in the afternoon and work late at night.

In July last year, Chuong My, along with two other suburban districts of Quoc Oai and Thach That, were hit hard by heavy downpours, and most of their areas was left under water. Thousands of houses in the three districts were submerged for five to seven meters for weeks and locals had to move around in boats.

Hanoi chairman Nguyen Duc Chung had said then that the city will look at ways to resettle residents in flood-prone areas in its outskirts to higher land.
