From this article you will learn:
In one of the large tenders, the formal requirement was an almost 10-year warranty and the technical requirement was the use of light PVC fabric (650g/sq m). And here, consultations with manufacturers of such technical fabrics from Europe would suffice as none of them will provide even a 3-year warranty for dams filled with water (usually contaminated or in contact with it) because such materials are intended for roofs and walls of tent halls. In practice, such a 10-year warranty for a barrier made of a de facto “tent tarpaulin” usually lasts until the first or second use, after which mechanical damage may most often occur. Because the material of such a barrier is simply “too thin” – low grammage (650g/m2), basic polyester weave (1100 dtex, tensile strength 2800N/5cm). In addition, of course, the number of layers and the chemical composition of the fabric coating are responsible for UV resistance and resistance to chemical compounds. The “PVC” itself in the description of the fabric does not provide this, otherwise we would make fertilizer tanks from fabrics for banners (both fabrics are “PVC coated”).
In practice, as confirmed by our conversations with users of various dams, 650g fabric barriers are often damaged (by stones or floating objects), require repairs and, with great luck, are reusable. With our knowledge of technical fabrics (we have been producing flexible tanks for over 10 years) and the desire to improve the world, we decided to create our own barrier proposal.
We went with our prototypes to selected units, but as it turned out, this was only the beginning. Because conclusions are one thing, and their technical implementation in the product is another… and it took another several months (including more or less successful attempts).
We also came back from the tests with a very important conclusion:
Whether it is a rigid plastic barrier, a flexible barrier, coated foil or traditional sandbags – each solution has its pros and cons that you need to know about in order to adapt them to the threat that may occur. We will try to describe it in a separate article.
The mobile and flexible Exflooder flood barrier, 5 meters long and 45 cm in diameter, is an effective alternative to traditional sandbags. It was designed on the basis of conclusions from the course of flood protection activities with units of the Volunteer Fire Department and the State Fire Service from several regions of Poland, as well as tests performed with selected units. It has a single-chamber structure, a self-supporting tank which, when filled with water, takes the shape of a flattened cylinder.
The barrier is made of multi-layer technical fabric with a weight of 900 g/m² and specially selected properties. The material ensures tightness when exposed to weather conditions and UV radiation, as well as increased resistance to mold and fungi during storage. In the structure of the dam itself, elements have been added to facilitate its filling, emptying, anchoring and connection. The volume of an empty, assembled dam is only a few percent of its capacity. Thanks to this, the barrier can be folded and moved many times.
