1. Raise the floor above flood level
To begin with, architects should build structures above flood water levels to minimize damage if flooding occurs. With flood level information in the area, architects can distinguish which heights to lift the building and how they should do so. A popular enhancement is to build structures on columns like stilt houses. In other cases, a firm foundation may be raised higher. For more specific information on what to do, architects should assess the climate and flood history of their area and refer to the information available online.
2. Using anti-flood materials
Flood-proof materials are materials that can be in contact with floodwaters for at least 72 hours without causing major damage. Flood water can be standing or fast flowing water, and in most cases displaced foundation walls, structure collapsing … Damage statistics show any damage that requires a lot of work. clean or cost-effective repairs, such as painting. To prevent these damage, the floodproof material must be durable and resistant to high humidity. Examples include concrete, glazed tiles, and foam insulation, steel hardware, pressure-treated plywood, ceramic tiles, water-resistant glue, polyester epoxy paint, etc.
3. Apply coatings, sealants and waterproof veneer
There are two different types of flood protection: wet and dry. Dry flood protection prevents flood water intrusion, while wet resistance allows flood resistance to enter the home. Waterproof coatings, sealants and laminates belong to the past, as they prevent water from entering the interior. A waterproof board may consist of a layer of bricks supported by a waterproof membrane, sealing the outer walls against water ingress. In interior walls, architects should use washable foam insulation in areas below flood water. Likewise, coatings and sealants can be applied to foundations, walls, windows and doors to prevent floodwater from entering the home through cracks, as these openings are rarely designed to watertight or flood-resistant.
4. Raise or install HVAC flood proof equipment, mechanical components, plumbing and electrical systems
Placing service equipment above flood protection is generally the best way to protect it. Such equipment includes heating, ventilation, air conditioning, plumbing equipment, plumbing fixtures, plumbing and electrical equipment including, gauges, and switch and socket. If these parts are submerged in floodwaters for even a short time, they can be severely damaged and need to be replaced. Electrical equipment in particular can present a risk of fire if it is short-circuited. Ideally these components are raised above the flood water level, but if necessary, they can be designed to prevent damage from flooding, whether through waterproof enclosures, barriers, protective coatings, or Other techniques for protecting vulnerable components.
5. Fix the fuel tank
Uncontrolled fuel tanks are highly susceptible to movement by flood waters, and floods can puncture tank walls, damage other assets, and cause pollution if the supply lines are torn. Even the landfill tank can be pushed to the surface of the water by buoyancy (oil is lighter than water. Therefore, it is imperative that the fuel tanks be fixed by attaching them to concrete slabs heavy enough to resist the force. floodwaters, or by threading belts over them and attaching them to anchors on the ground.
6. Install foundation vents
An example of flood protection is the installation of vents in the foundation, which allow floodwater to flow through the house instead of being deposited around. While this solution may seem like an counterintuitive solution due to the damage it can do to the interior of the house, it actually provides an outlet for floodwater and reduces the damaging pressure. that floodwaters cause on windows and walls. If the sub-basement interior is prepared with flood-resistant materials, hydrostatic holes and the main unit protected, damage can be limited, although post-flood cleaning is necessary. Likewise, a septic tank pump is a type of device used to pump water out of basements where flooding occurs frequently. Septic tank pumps with spare batteries are recommended to allow them to continue operating during a power outage.
7. Construction of barriers
Placing a permanent fence around the structure in question can prevent floodwater from overflowing it. Such fences should be constructed using flood retaining walls made of concrete or brick, or by using dykes made of compact layers of impervious earth. Although this solution seems to be the simplest or most obvious, both the floodwaters’ walls and dykes require continuous maintenance. In addition, the dyke requires a considerable amount of land and soil materials that can be used for construction.
8. Install the drain back valve of the drain
The sewer back-flush valves prevent sewage from overflowing the home. In some flood-prone areas this is a common occurrence, which can cause damage that is difficult to repair and endanger the health of the living. In general, gate valves are preferred over cap valves because of their better sealing ability against flood pressure.
9. Use inclined lawns
One final method that architects can use to minimize flood damage is to tilt the lawn in the front of the house. If the lawn is tilted towards the house, rain water will collect around the house. Conversely, leaning out will wash away rainwater. To achieve this, lawns should use heavy soils that contain a mixture of clay and sand, allowing surface runoff to pour into a more suitable place such as street trenches.
