The purpose is the same as that of levees and floodwalls- to protect the surrounding homes, businesses and other buildings from damage caused by flooding. SeawallsĪ seawall acts like a blend of levees and floodwalls, as it is a man-made, concrete slope found near the shoreline on beaches. In contrast, a precast concrete floodwall can withstand the tests of time and weather, making it a better investment for protecting a local area. At best, an eroding levee will need much maintenance long-term and must be rebuilt periodically. Using soil, grass and other natural earthen elements for a levee can lead to erosion during a flood, which negates its purpose. However, levees are made from the earth, like a giant hill alongside a river or shoreline. They are usually found along the banks of rivers, can be natural or man-made, and basically act like a hill to keep water from immediately rising into the local area. LeveesĪ levee is designed to do a similar job as a floodwall: protect the surrounding area from flooding waters. Precast concrete connectors are the strongest around and can be made to fit any customized size, ensuring they’ll hold when the time comes. Without precise connectors, these gates would not work properly, or sections of wall could be washed away from the force of running floodwater. Floodgates are able to be raised when water needs to be let out of the contained space, thus keeping the area dry and safe. Most importantly, however, are the connectors that bind the sections of wall and create the floodgates that are found periodically spaced down the length of the wall. By building flood walls with precast concrete, they can be made to fit precisely, without having to accommodate the environment as they build. Floodwalls are often built with the integrity of the city in mind, so they don’t distract from the aesthetic or historical value of the area. Here’s what we’ve learned that we hope will help you make a wise decision about flood prevention- before it’s too late.įloodwalls are concrete structures designed around a city or major residential area that blocks water from rising and seeping into buildings and other structures. Fortunately, Permacast Precast Concrete Walls & Fences knows a little bit about floodwalls, levees and seawalls- all common structures in Florida and Texas, where hurricanes and other extreme weather bring plenty of water to major cities and coastal regions. There are many different ways to prevent the damage caused by flooding, and it’s important to know which type of flooding could most impact the area you’re hoping to protect. That needs to be done long before the flood waters come along. When flood waters start to rise, it’s too late to start thinking about protecting your city, business or home from flooding.
