FlexMac DT
Rapid deployable flood protection barriers
FlexMacDT is used as a fast to deploy barrier for flood protection, raise embankments and to provide buttressing support for temporary works.
It consists of a multicellular structure made of hexagonal double twisted wire mesh. The mesh is reinforced with vertical steel rods and internally lined with a non-woven geotextile sleeve.
The cellular structure is filled in-situ with locally available fill material to provide a barrier system against rising water, or to buttress excavations in temporary works.
FlexMac DT units are joined to each other longitudinally by using connecting pins to obtain the required length of the structure.
The hexagonal double twisted wire mesh is engineered to provide strength with flexibility. This gives the structure greater flexibility than more rigid solutions and is ideal in areas where differential settlement could occur.
Once the FlexMac DT unit has served its emergency use, it is possible to reuse the unit, by carefully lifting it, allowing the fill material to fall out. The success of this operation depends on the original fill material used and the condition of the unit post-use.

CEBU TRANSCENTRAL HIGHWAY
Philippines
The Cebu Transcentral Highway is located in Barangay Cansamoroy, Balamban, in the province of Cebu, and is approximately 33 kilometers long. It’s one of Cebu’s most ground-breaking transportation development as it makes land travel to several destinations in Cebu’s central and northwestern regions faster and easier. However, certain sections in Balamban Transcentral Highway imposed danger to the infrastructure and motorists passing by. Contractors and designers sought to prevent hazards such as falling rocks or boulders, landslides, and debris flows during heavy rainfall or typhoons.

FLOOD EMERGENCY RESPONSE PROJECT
Canada
In spring 2019 vast areas in eastern Ontario, southern Quebec and New Brunswick experienced exceptional flooding due to a combination of events such as heavy rains, melting snow and sudden temperature increase. Just two years earlier, in 2017, a similar flood affected the same areas along the Ottawa River causing severe infrastructure and private properties damage. Unfortunately, the number of flood-related disasters has been growing in the past years and it does not seem to slow down. For this reason, Canadian public agencies are funding projects to implement long-term flood mitigation measures and flood emergency response plans that include ready-to-use solutions that can be quickly deployed to protect assets and lives. After the 2017-flood, Nicolet, a small town along the St. Lawrence River in the province of Quebec, realized that every year the risk of flooding for certain areas has been increasing due to climate change therefore decided to proactively purchase in advance a product that can be reused.
