Flood barriers provide strong protection for homes and act as the first defense against rising water. If you install them correctly, they can block approximately 90% to 95% of floodwater access toward your property. Most flood barriers can handle water levels between 600 mm and 900 mm (2 to 3 feet).
Therefore, you should install flood barriers around buildings for safety during flash floods and moderate flooding. You can read this topic to learn about a flood barrier installation method. So, you can avoid mistakes and get the best possible protection from floods.
8 Steps For Flood Barrier Installation
1. Gather Required Tools and Materials
Before you start barrier installation, you should gather all the items and materials you need. Basic tools you must have include a tape measure, a pencil/chalk for marking plus cleaning supplies like a broom, brush or cloth.
You will also need the flood barriers (such as sandbags, water-activated barriers, aluminum or door-opening types) and a pair of gloves to protect your hands. Also, keep sand or water ready if your barrier needs filling.
2. Prepare Installation Surface
You have to identify all possible water entry points around your home such as doors, windows, garage openings and other low areas. Then you can decide the most important spots which you need to protect and mark them on a simple map.
After that, you need to clean and prepare the location. You must remove dirt, mud or any loose objects. It’s important to make sure the ground is stable, so you can properly set a flood barrier.
3. Choose Right Flood Barrier
To select the right flood barrier, you need to identify your home’s risk and water level. You should pick a barrier that matches your space. For instance: you can choose driveway flood barrier or door barrier if water level stays low in your area.
For medium flooding safety, modular flood panels or water-filled barriers are your ideal choice. We recommend that you to install flood gates, self-closing flood barriers, flip-up flood barriers or flood panels for high flood risk.
4. Position Your Flood Barrier
You now need to position each barrier directly in front of the entry point that you want to protect. Always make sure the bottom edge is flat and stable on the ground. Plus, you should align both sides carefully with the edges of doors or garage openings for full coverage.
Then, you need to adjust the barrier tightly against the surface with no gaps. You have to confirm that the height of the barrier is suitable for the expected water level.
5. Secure Barrier System
Now it’s time to secure the flood barriers properly. You should tighten all locks, clips, parts or joints. Further, we advise you to use an anchoring method based on your barrier type.
Some barriers are designed with built-in anchoring systems. But others require added support, such as sandbags or weights. This way, you can make sure the barrier is secured, so it does not shift during heavy rain or rising water.
6. Apply Seals & Waterproofing Materials
After you place flood barriers around your home, you should apply seals and waterproof materials. Never forget to check all edges where the barrier touches the ground and walls. You can use rubber seals, foam strips plus waterproof tape to close small gaps.
If your barrier includes gaskets or sealing strips, you must install them properly along the edges. Then, press them tightly along all sides to create a watertight seal. With this method, you can make your flood barrier fully strong and leak-proof.
7. Test For Stability and Water Resistance
Final inspection of the entire flood barrier placement is required to find problems before a flood occurs. For this, you need to look for any gaps and loose parts. Also, check the areas where the barrier does not fully touch the surface.
You can push the barrier gently to see if it stays stable and does not move. In case you find any weak spots, fix them right away.
Furthermore, you can pour a small amount of water on the outside of the barrier. And then, you need to watch closely for any leaks or seepage on the inside. If you see water passing through, you should adjust the barrier or add more sealing material.
8. Flood Barrier Maintenance After Installation
To keep your flood prevention system in good condition, you have to make sure its regular inspection. For example: you should check all barriers after heavy rain or storms.
If you find cracks or damaged sections, you have to repair or replace them as soon as possible. Our recommendation is simple in this matter. You can set a routine inspection schedule such as monthly checks for flood barriers.
Flood Barrier Installation Cost
The installation price of flood barriers varies based on type of barrier, property size, materials and installation requirements. Suppose, you choose an expandable flood barrier, then the expenses for its placement will be around $1500 and $3000 per unit.
For a door flood barrier set up, you need to spend between $500 to $2500 per door. However, the budget required for a self-closing flood barrier generally ranges between $8000 to more than $40000.
How Much Do Flood Barriers Cost?
Flood barrier prices mostly range from around $200 to more than $500+. The exact cost depends on the type, size, scale, and level of protection you need. For residential properties, modular flood gates cost between $700 per unit. But for larger commercial flood barriers, you need to spend more money.
To Conclude
A flood barrier can only protect your property when you choose the right flood barrier and install it correctly. But if you choose the wrong barrier, its perfect installation will not protect you well.
