A Look At The Pros And Cons Of Some Different Residential Flood Mitigation Solutions
In an area that has floods each home should have its own flood disaster protection. There will be general flood prevention done by the county but it often is not enough for everyone. Any property that has a lake, river, or pond nearby faces the possibility of flooding at some point. Preparedness is essential to saving a home.
Floods can be very minor or turn into absolute disaster. Damages to land, home structure and belongings can reach the thousands. An area that is susceptible to floods can make getting flood insurance expensive. It is best to carefully look over homeowners' policies and speak to the broker, because flooding often isn't covered.
Gutters full of debris and downspouts improperly installed can often be the cause of water coming into a home. These should be checked regularly and kept clean. The basement should be looked at, possibly by a professional to see what areas are in need of repair. Cracks will need to be repaired and sealed.
Building a berm is considered effective in redirecting flood water. This is a permanent solution for an area that has an ongoing flood problem each year. It is sometimes simply a mound of soil with a slope. A more permanent version is made with gravel, logs, or rocks. This is then layered with clay and finished with a layer of soil. To make sure the soil stays in place there should be some plantings put into it. It is important to be sure of the direction the water will be redirected.
As a temporary flood protection solution sandbags work well. These are usually provided by the county when there is a flood warning. It is best to keep them partially filled then finish filling them when it is time to place them on the property. These will work for water rising up to two feet.
Another solution that can be used again and again is an aluminum flood barrier. Metal fasteners are put in place next to doors and windows on ground level. Aluminum panels are then fastened to them when the waters rise. When protecting the land around the home, metal is set into the concrete where vertical posts can be fastened. Between these posts the aluminum panels are placed. While the first type will keep out water, the second do not stand up well to standing water and it can seep in.
Using a sump pump is an alternative that can be much cheaper than some of the other choices. It is also more convenient than most as it is not necessary to be home for it to start doing its job. Once water has entered a basement it needs to be dried out as soon as possible. With an automatic pump, when the water reaches a certain level the pump will start. If the pump is set in a hole a couple of inches below floor level the pump can start sooner.
Appliances in the basement should be on concrete a foot off the floor. This will keep them from being damaged by the water. Prevention is the best flood mitigation. It costs up front for any of the flood protection system solutions discussed above but it will still be less than what flood damage can cause in a home.
