FlexMac™ DT, a disaster emergency response solution in Semarang – Demak
The occurrence of extreme tides in May 2022 in the city of Semarang, can trigger another flood event. With the sea level reaching more than 210 cm, the Ministry of Public Works made an emergency response effort by installing a new embankment to control seawater in the area.
Maccaferri Indonesia proposes using FlexMac™ DT as part of the embankment for disaster emergency response solutions because the installation is much faster. With an aesthetically-pleasing shape, the FlexMac™ DT also offers several other benefits such as no compaction, easy to stack, stable, flexible filling material, and can become part of a permanent structure.
Located in the northern part of Central Java, Semarang is subject to flooding caused by high tides. In May 2022, the sea level reached more than 210 cm above sea level which could trigger another flood event. The tide is considered extreme compared to tidal records for the last 5 years from 2017 to 2021, with the highest recorded at more than 180 cm above sea level. The Ministry of Public Works is making efforts to deal with emergencies such as installing new embankments and coordinating with local officials to prepare flood control facilities.
As a contractor, KSO Nindya Karya – Mataram has been instructed to install an embankment near Ahmad Yani International Airport to control the flow of seawater in the area. The embankment is built on bamboo poles as deep as 4 meters as the foundation. The embankment is made 5 meters high with a height of 3 meters of an earthen embankment and 2 meters of FlexMac™ DT from Maccaferri Indonesia above it.
Maccaferri Indonesia proposes using FlexMac™ DT as part of the embankment. Unlike the Geo Bag/Jumbo Bag, the FlexMac™ DT offers quick installation with minimal effort because the FlexMac™ DT is best suited for emergency response. With an aesthetically-pleasing shape, the FlexMac™ DT also offers several other benefits such as no compaction, easy to stack, stable, flexible filling material, and can become part of a permanent structure.
The use of FlexMac™ DT as a flood barrier has been around for decades in Europe and America, but it is still relatively new in Indonesia. Maccaferri Indonesia takes this opportunity to introduce the multi-benefits of the FlexMac™ DT and its versatility.
