Flood barriers come in a variety of lengths and sizes. They are built according to the width of the required entrance. The panels are made from either aluminium or composite. While both are strong and reliable, composite panels are limited to 1.5m in length.

Access posts are permanently installed on either side of the entrance. They can be up to 2m (2000mm) in height. They can also be connected to form a longer, continuous flood wall. This means you don’t have to install flood barriers on a wall. They can be freestanding so that specific areas or stations are protected.

What else should you consider when choosing a flood barrier? One of the most important factors is the location and nature of the area where you intend to use the flood barrier. The ground type, topography and distance from flood-prone areas will significantly influence your choice of solution. For example, in areas with soft soil or flat surfaces, flexible flood barriers such as Exflooder casings may be ideal as they can adapt to the terrain. Conversely, in rocky or very rugged areas, more permanent and stable solutions such as modular aluminium barriers may be more effective due to their superior strength and stability.

Response time is also crucial. In an emergency, it is beneficial to choose a solution that can be quickly installed and deployed. Traditional methods, such as sandbags, may not be enough because it takes time to make them waterproof. In this case, portable flood barriers that can be quickly installed and filled with water are more effective. In areas where water levels may rise quickly, the speed of barrier installation is critical to the success of flood protection.

Budget is another important consideration when choosing a flood barrier. Depending on the solution chosen, the cost of purchasing, installing, and maintaining the barrier can vary greatly. Traditional methods such as sandbags are relatively cheap but require a lot of labor and materials, which can increase long-term costs. In contrast, modern solutions such as modular barriers or flexible PVC sleeves may cost more to purchase, but their durability and ease of use can help reduce running costs.

Last but not least, the availability of human and technical resources. The choice of barrier needs to be tailored to the number of people who will install the barrier, the availability of equipment, and the level of skill required for installation or maintenance.
