Garage Flood Protection
Don't let floodwater enter your property
Being prepared is vital for flood defence
Garages are often the first to flood and the last to get attention. But with vehicles, tools, stored items, and even utility connections at risk, they deserve proper protection.
Our Garage Flood Protection range is built to block water at key access points, from up-and-over doors to side entrances and connected driveways. Each solution is easy to deploy, reliable under pressure, and tailored to the unique challenges garage spaces face during heavy rainfall or rising water.
Explore the collection and keep your garage, and everything in it, safe, dry, and ready for whatever the weather throws your way.

How do you divert water away from your garage?
Flood protection starts with prevention—and one of the smartest ways to reduce the risk to your garage is by managing how water moves around your property.
Start with smart drainage and landscaping
To stop water before it reaches your garage door, a few structural adjustments can make a big difference:
- Install French drains or trench drains near the garage threshold to collect and redirect water away
- Regrade the surrounding landscape, ensuring the ground slopes gently away from the garage rather than toward it
- Use permeable paving or gravel around the driveway area to encourage better water absorption and reduce pooling
These passive defences help divert rainwater and surface runoff before it becomes a problem.
Strengthen your defence with fast-acting flood protection products
Structural changes alone may not be enough, especially during flash floods or prolonged rain. That’s where our flood protection products come into play.
- Flood Cubes can be positioned along garage entrances or boundaries to create an instant, water-diverting barrier
- Osmo Flood Barriers offer a lightweight, modular solution that’s ideal for wider openings; easy to deploy, stack, and reposition as needed
These products help guide floodwater away from your garage and towards safer drainage zones, preventing it from breaching entry points
Combine strategies for a complete defence
Using flood barriers alongside smart drainage and landscaping gives you layered protection, reducing both the likelihood and severity of flooding.
This combined approach doesn’t just protect your garage, it helps manage water across your entire property. By diverting water effectively, reinforcing key entry points, and creating buffer zones, you’ll dramatically lower the risk of flood-related damage to your home, vehicles, and stored belongings.
Tips for Using Sandbag Alternatives
Sandbag alternatives like Floodsax offer several advantages, including ease of storage, quick deployment, and reusability. Here are some tips for using these alternatives effectively:
- Preparation: Keep Floodsax or similar products in an easily accessible location for quick deployment in case of sudden flood warnings.
- Activation: Follow the product instructions for activation, ensuring they're ready to absorb water and expand to their full size.
- Placement: Strategically place the barriers at entry points, ensuring there are no gaps for water to seep through. Overlapping and layering can enhance effectiveness.
- Post-Event: Once the floodwater recedes, dispose of any contaminated products as per the product instructions.
Garages need not be vulnerable to flooding. With the right planning and our tailored Garage Flood Protection products, you can safeguard this essential area from water damage effectively. Explore our solutions today and take a proactive step towards comprehensive flood defence for your home.
Let customers speak for us
from 232 reviewsThe advertising was persuasive so we ordered it. It came in good order and proved to be the right fit and easy to instal. The proof as to its efficiency now depends on the next flooding event (which we expect but rather fear). If that happens you can expect another review!

After receiving the flood shield and realising we needed the shorter clips, you promptly sent them with no issues.
Today we have swapped the clips and fitted it to the door. It was lightweight, and very easy to install.
Really hoping we won’t need to use it, but it is very reassuring to know that if the worse does happen, my mum is able to install the Floodshield.
Your customer service has been brilliant and your product is giving my mum peace of mind should the worst happen.

Hi I found the barrier easy to fit lightweight bit disappointing the writing upside down on , fortunately I’ve not had to use it yet so still waiting to test it

It arrived today just in time for Christmas!!

Flood gate received and very easy to fit, had to order longer screws, but they arrived quickly and so easy to fit. I hope i never have to use it!!

The shield fits well, have not had to use it since last getting flooded. A great product. Delivery was promised , but kept getting delayed. Glad to see your website now states the correct time of 3 weeks.

Floodshield is an excellent product however my order was damaged I ordered 2 floodshield barriers . 1 barrier was perfect the other badly scratched. I arranged for it to be returned however it was not picked up when promised then was told that the new one would be delivered that same week which it wasn't. When contacting floodshield I was told it would be delivered to me Monday 28/10/24 however it was not so once again I contacted floodshield left a message has no one was available and now if is 30/10/24 and I have still not received my replacement floodshield barrier!
I am sad to say that the customer service that floodshield supplies is extremely poor but the floodshield barrier itself is excellent.

Not used yet hope never have to but it gives me a little peace of mind knowing that it is here

Haven’t actually used it yet, but the quality looks and feels good.

Hope to solve a basement toilet backflow problem, will let you know after the next big rain event.

We have just moved to this area and with the unpresented amount of rain in 1 day our garage flooded. I looked up items that would help keep the water out in future and bought a Osmo flood barrier. It has worked wonderfully and I wish I had known about the company before. So easy to use and have ordered a couple more just in case we need them in the future.

It helped to keep out the river, not flooded this time around

I live in an area where we are only 65 - 85ft above sea level. Every winter season we are all waterlogged. Occasionally, we have problems with backflow, but not now I have a Toilet Stopper! What a simple, but great idea! I can’t recommend them enough. I’m buying another one for a friend of mine. Thank you to whoever thought of this.
