Why flood protection matters.
The Dam It Difference: Flood Barriers in St Petersburg
2.5X Strength & Seal
Aerospace Grade aluminum that is 2.5X the thickness and density of most competing products, allowing it to withstand a jaw dropping 40,000+ PSI. Thicker, larger, and denser 2-phase age-resistant EPDM gaskets for maximum seal and longevity.
Dam It Difference
Founded by a team with over a decade of experience in aluminum manufacturing, our flood barriers are trusted by marquee homes, Fortune 500 companies, HOA communities, cities and municipalities.
Built to withstand up to 10ft of water. Rustproof reinforced aluminum, solid cast stainless steel components, and rubberized gaskets that increase in strength when holding back water.
Designed for Every Application
Engineered for rapid, reliable deployment season after season. Unlike sandbags, plywood, and temporary barriers that fail or wash away, our systems provide structural integrity you can trust.
View System Specifications
Our systems use aerospace-grade aluminum cross sections, reinforced channel depth, and dual-phase EPDM compression gaskets engineered to a higher standard than most competing systems on the market.
The Dam It Advantage

EXCELLENTTrustindex verifies that the original source of the review is Google. Lee at Dam it Defense was great. Truly, a quality product and an amazing team.. They are quite busy, but once installed it was worth the wait. Their product is in a class of its own and in high demand.Posted on GoogleTrustindex verifies that the original source of the review is Google. Excellent experience all around starting with Mr. Bass, who came to the house for initial inspection and estimate, to the concrete crew whose team- leader ensured excellent cosmetic details and then finally the install crew led by Mr. Michael. The delivered product is great quality, the after installation customer follow up ensured that I was happy and that any trivial details not to my satisfaction were adressed promptly. After dealing with the horrible experience of the failure of traditional “sandbags” and catastrophic flooding, I feel much better prepared for upcoming hurricane seasons. Highly recommend this company over the competitors- they are local, their product is superior and their pricing better.Posted on GoogleTrustindex verifies that the original source of the review is Google. I have Peace of Mind!! After my home was destroyed by Hurricane Helene with the floodwaters and being displaced for 9 months and having to rebuild my home. I started researching the flood barriers to prevent this again. Had 4 companies come out and Lee Bass from Dam it Defense felt to me the most knowledgeable and trustworthy. He put me at ease and did not pressure me, he answered all of my concerns and went as far as to arrange a meeting (my request) for me to see the product installed on a home and I could ask more questions! Lee is top notch! The entire team that I worked with are all great! They earned my trust! No more hurricane flood waters in my house! Thanks to Dam It DefensePosted on GoogleTrustindex verifies that the original source of the review is Google. My home was flooded during the September 2024 hurricane events in Florida. We had to completely remove and renovate the lower level of our home, which has been a nightmare. I was approached by Lee Bass, a Dam It Defense representative, who told me about their product. I decided to move forward and purchase their flood defense product as insurance against future flood damage. They kept me informed about the progress of my project while I was awaiting final installation. Once my home was ready for final installation, the process only took a couple days. Their concrete team removed the pavers around my sliding doors to install footers to create a tight seal. The installation team was quick and efficient. I how have the barrier brackets permanently fixed to all of my doorways around my home, and they almost blend in with the normal decor of the home. I plan on painting them the same color to have them blend even further. I hope to never have to use their product, but now I have peace of mind to protect against flooding in the future, and I am so pleased that I never have to wait in sandbag lines again.Posted on GoogleTrustindex verifies that the original source of the review is Google. Lee Bass the salesman did a great job for us I would recommend him to everyonePosted on GoogleTrustindex verifies that the original source of the review is Google. Here's the deal breaker with Dam It Defense versus everyone else... the service! Lee and his team not only installed the unit in a few hours but they gave me a tutorial afterwards with options on set up and storage. More importantly the product is visually and virtually superior. While im not looking forward to hurricane season, I know that with this dam product, my line of defense is impenetrable!Posted on GoogleTrustindex verifies that the original source of the review is Google. The company was easy to work with and did what they said they would do.Posted on GoogleTrustindex verifies that the original source of the review is Google. Lee, Matt and John did a fantastic job! They worked with me and explained every step of the process and how these flood gates work to protect the home. Great communication and attention to detail all around. Best part is they will store the flood gates and come out and set them up when a storm is coming so the panels won’t take up space in the garage. Amazing workPosted on GoogleTrustindex verifies that the original source of the review is Google. Installation was easy. System is better then I expected. Mike answered many and all questions. Andrea the install team were great . I feel very good with my purchase and I am not looking forward to another hurricane but at least I feel confident and proactive if one comes. Thank you Dam it Defense team.Posted on GoogleTrustindex verifies that the original source of the review is Google. After being taken out by Helene and a very lengthy rebuild, we found Dam It Defense to be the prevention method that worked best for our coastal home on LBK. Clay was great through the whole process - quotes, demonstration and explanations. The fact that the developers and owners were motivated by their own experiences with Helene and the flood damage, as well as the products resistance to salt water, gave us an extra layer of confidence. The installation crew was great and Michael followed up a number of times - even on his day off. Being part time residents, the storage and installation option for pending storms saves flights back and forth to storm prep. While we hope to never experience this again and is the one product I hope I never have to use, I’m thankful that it serves as an extra layer of protection and provides some peace of mind.
