The devastating effects of flooding are all too familiar for many property owners. Just a few inches of water can cause tens of thousands of dollars in damage, leaving countless homes and businesses in disrepair. But taking measures to prevent flood damage can help protect your construction project from costly repairs and provide peace of mind for all involved. In this article, we'll discuss the causes of flooding and 9 practical solutions to combat it in your construction project. These solutions will help you prepare your new construction project to withstand the worst weather conditions, from raised foundations to flood-resistant materials to drainage modifications.
What Causes Flooding?
Flood damage can be a costly problem when building a new construction project, but it's important to understand the causes of flooding to know how to prevent it. Flooding can be caused by many different factors and can be caused by both natural disasters and man-made activities.
Natural disasters like hurricanes, heavy rains, and rising groundwater can cause flooding. Hurricanes bring large amounts of water inland, which can cause rivers and streams to overflow onto lower-lying land. Heavy rains can overwhelm storm drains and fill up local rivers and streams. Lastly, if an area's groundwater level rises above the land's level, it can cause flooding as well.
Man-made activities, such as dams, can also cause flooding. Dams are built to contain and control the water by diverting it from areas prone to flooding. Unfortunately, if a dam is not maintained properly or has too much water, it can breach the banks and cause flooding downstream.
Furthermore, inadequate drainage can be a contributing factor to local flooding. If the gutters and downspouts of a property are blocked or clogged, this can lead to standing water that can easily flood a nearby area. Poor construction practices, such as grading a property so the water drains onto another property, can also lead to flooding.
9 Practical Solutions to Combat Flooding
Raised foundations
Constructing raised foundations is one of the most effective ways to protect your new construction project from costly flood damage. Building up the structure's foundation allows it to be elevated above any potential floodwaters, minimizing the potential for serious damage to the building or its foundation. Elevating the foundation can be done by building a raised frame or increasing the height of the walls. Additionally, incorporating other measures, such as waterproof membranes, improved drainage, and internal finishes, can provide further protection against flooding.
Elevated first floors
One key way of avoiding costly flood damage in your new construction project is to construct your first floor slightly elevated from the ground level. This simple preventive measure will help ensure that any potential flooding will not affect your first level. Opt for raised foundations with higher elevation to guard against serious water damage. Additionally, investing in waterproof membranes and sealing materials, such as rubber or plastic, can help further protect your structure and the contents of your home. Taking the time before construction to planning for these preventative measures will save time, money, and heartache.
Waterproof membranes
Installing waterproof membranes is one of the most effective ways to prevent costly flood damage to your new construction project. These membranes are made of sturdy materials that form a barrier to keep water out and protect the structure from water damage. They are available in various sizes and thicknesses and can be applied to the structure's interior and exterior surfaces. In addition, these membranes can help reduce the amount of water that enters your building during heavy rains and storms, reducing the likelihood of costly flood damage.
Flood vents
Installing flood vents is one of the most effective ways to reduce the costs associated with flooding. Flood vents allow water to pass through to the other side of a structure while providing a barrier against most of the water. These vents are critical to helping reduce the costs associated with flood damage as they allow floodwater to pass through without causing harm to the structure or its contents. Additionally, flood vents can reduce the likelihood of flooding in areas prone to flooding due to their ability to limit the amount of water entering a building. When installing flood vents, it is important to use a reliable, high-quality product that will stand up to the test of time and withstand years of flooding.
Flood-resistant materials
An important factor to consider in any new construction project is the risk of flood damage. A good option is to use materials more resistant to flood damage to reduce the risk potential and potential costs associated with it. For example, brick and mortar are more durable than wood, and concrete is more waterproof, durable, and corrosion-resistant than metal. It's important to be aware of the building codes for your area since some counties and cities require specific flood-resistant materials for certain types of construction. Researching which materials are best for your project and budget can help ensure your new construction is well-equipped to resist flooding and other potential risks.
Building shape and orientation
When it comes to avoiding costly flood damage in your new construction project, the shape and orientation of the building can play an important role. For instance, buildings with steeply pitched, gabled roofs and eaves that extend out from the outside walls provide better protection from flooding than buildings with a flat roofs and no eaves. Additionally, the angle of the roof should be considered – the steeper the angle, the better the protection from flooding. Orienting the building in a direction that makes it as difficult as possible for floodwaters to enter the building can also provide an extra layer of protection. For example, a building with a gabled roof that faces the direction of a river or floodplain can make it more difficult for flooding to cause damage.
Drainage modifications
One of the most important steps in avoiding costly flood damage in your new construction project is to consider drainage modifications. Poor drainage can damage your project, causing flooding, water damage, and expensive repairs. You can prevent flooding and mitigate the effects of heavy rainfall by carefully designing and installing appropriate drainage features, such as filter drains, storm drains, and surface drains. Additionally, implementing green infrastructure techniques, such as permeable paving, rain gardens, and green roofs, can help reduce property flooding and protect your buildings from costly flood damage.
Retaining walls
Retaining walls are an important structural component when considering flood damage prevention. An effective retaining wall is designed to contain and control flooding, preventing or minimizing water from entering and damaging the structure. In new construction, it is important to properly design and build an effective retaining wall to provide long-term protection from potential flood damage in the future. Additionally, proper maintenance is essential to retaining walls, as any cracks or weakened areas may lead to failure during a flood event. By consulting a professional and properly installing and maintaining a retaining wall, homeowners can prevent costly flood damage from affecting their new construction projects.
Flood Insurance
To prevent costly flood damage, the first step is to ensure the building meets all the necessary requirements for inclusion in the National Flood Insurance Program (NFIP). This program has been created to help protect homeowners from the financial consequences of flooding. Additionally, it is essential to ensure that any new construction project complies with the NFIP Flood Insurance Rate Map (FIRM) zoning requirements. Additionally, it is essential to purchasing adequate flood insurance to cover any damage that may occur. By taking these steps, homeowners can protect their investments and avoid expensive flood damage in the event of a flood.
