FIELD OF THE INVENTION:
[0001] The present invention is referred to a method for protecting houses and buildings
from floodwaters. More particularly, it is referred to a method for protecting houses,
buildings and structures from floodwaters using sandbags.
BACKGROUND OF THE INVENTION:
[0002] Floods occur when there is an overflow of water from its natural or artificial boundaries,
resulting in inundation of the surrounding areas. There are various reasons why floods
occur, including natural causes, human activities, and climate change.
[0003] Natural Causes: Natural causes are among the most common reasons why floods occur. These include
heavy rainfall, hurricanes, typhoons, and snowmelt. When there is too much rainfall
or melting snow, the water accumulates, and if the ground is already saturated, the
water flows into rivers, lakes, and other water bodies, causing them to overflow and
flood nearby areas.
[0004] Human Activities: Human activities can also contribute to the occurrence of floods. These activities
include deforestation, urbanization, land use changes, and construction activities.
Deforestation, for example, removes vegetation cover, which reduces the ability of
the soil to absorb water, and this can lead to increased runoff and flooding. Urbanization
can also increase the number of impervious surfaces, such as concrete and asphalt,
which reduce the soil's ability to absorb water, leading to increased runoff and flooding.
[0005] Climate Change: Climate change is another reason why floods occur. Climate change can cause an increase
in the frequency and intensity of extreme weather events, such as heavy rainfall and
hurricanes. Rising sea levels due to melting glaciers and ice caps can also cause
flooding in coastal areas. Climate change can also cause changes in precipitation
patterns, leading to droughts followed by heavy rainfall, which can increase the risk
of flooding.
[0006] In conclusion, floods occur due to a combination of natural causes, human activities,
and climate change. Heavy rainfall, hurricanes, typhoons, and snowmelt are some of
the natural causes of floods, while deforestation, urbanization, land use changes,
and construction activities are some of the human activities that can contribute to
flooding. Climate change can also cause an increase in the frequency and intensity
of extreme weather events, which can lead to flooding. It is important to understand
the causes of floods and take appropriate measures to reduce their impact on people
and the environment.
[0007] Every time a floods occur they are among the most destructive natural disasters,
and they can have a significant impact on all type of private property, especially
houses. Floodwater can damage a house in several ways, including structural damage,
water damage, and mold growth.
[0008] Floodwaters can cause significant structural damage to a house. The water pressure
can cause walls to bow or collapse, and the foundation can shift or crack. The structural
damage can make the house unsafe to live in and require expensive repairs. In some
cases, the damage may be severe enough to require the house to be demolished.
[0009] Floodwaters can also cause water damage to a house. The water can seep into walls,
floors, and ceilings, causing damage to the insulation, drywall, and electrical wiring.
The water can also damage appliances, furniture, and personal belongings. Water damage
can be extensive and may require extensive repairs, including replacing damaged flooring,
drywall, and electrical wiring.
[0010] Mold growth is a significant concern after a flood. The moisture from the flood can
create ideal conditions for mold to grow. Mold can grow quickly and cause health problems,
such as respiratory issues and allergies. Mold growth can also cause structural damage
to a house, as it can weaken the walls and floors.
[0011] Floodwaters can cause electrical damage to a house. Water and electricity are a dangerous
combination, and floodwaters can damage electrical systems and appliances. Electrical
damage can cause power outages and increase the risk of electrical fires. In some
cases, the electrical damage may require rewiring the entire house.
[0012] Floodwaters can also lead to pest infestations. The water can displace pests, such
as rodents and insects, and they may seek shelter in the house. Pest infestations
can be challenging to control and may require professional pest control services.
[0013] The general impact of floodwaters on a house can be significant. The damage can be
structural, such as causing walls to bow or collapse, or it can be water damage, mold
growth, electrical damage, or pest infestation. It is essential to take necessary
precautions, such as elevating the house, installing flood barriers, waterproofing,
and purchasing flood insurance, to protect a house from floodwaters. Homeowners should
also take immediate action after a flood, such as removing standing water, drying
the house, and disinfecting affected areas, to minimize the damage and prevent mold
growth.
[0014] With the increasing frequency and intensity of floods in recent times, it is important
to take necessary precautions and measures to protect homes from floodwaters. Some
of the effective ways to protect a house from floodwaters are:
[0015] Elevate the house: One of the most effective ways to protect a house from floodwaters is to elevate
the house. Elevating a house can be a significant investment, but it can save homeowners
from significant damage caused by floodwaters. Elevating the house to a height above
the flood level is a long-term solution to protect the house from future floods.
[0016] Install Flood Barriers: Flood barriers can be installed around the house to prevent floodwaters from entering
the house. Flood barriers can be made of different materials such as sandbags, water-filled
barriers, or inflatable barriers. These barriers are particularly useful in areas
where flooding is common and can be set up quickly when a flood warning is issued.
[0017] Waterproofing: Waterproofing the basement or the foundation walls can significantly reduce the
amount of water that enters the house during a flood. There are several ways to waterproof
a house, such as applying sealants, installing drainage systems, and using waterproof
coatings. Homeowners should also ensure that the sump pump is working correctly and
has a backup power source.
[0018] Landscaping: Proper landscaping can help to protect a house from floodwaters. Homeowners should
consider planting trees and plants that are flood-resistant and absorbent. The plants
and trees can help to slow down the flow of floodwaters, and the roots can help to
stabilize the soil. Homeowners should also ensure that the ground around the house
slopes away from the house, so that water does not collect around the foundation.
[0019] From all the alternatives mentioned above, flood barriers are essential in protecting
a house from floodwaters. There are different types of flood barriers available in
the market, each with its unique features and advantages. In this essay, we will discuss
some of the most common types of flood barriers used to protect a house from floodwaters.
[0020] Sandbags: Sandbags are one of the most common types of flood barriers used to protect a house
from floodwaters. They are relatively inexpensive and can be easily filled with sand
or soil. Sandbags can be stacked around the house to form a barrier, preventing floodwaters
from entering. However, sandbags require a considerable amount of labor to fill and
stack, and they may not be effective against high floodwaters.
[0021] Using sandbags to protect a house from floodwaters can be an effective temporary
measure, but it also has some potential drawbacks and limitations:
[0022] Labor-intensive: Filling sandbags and stacking them in place can be a time-consuming and physically
demanding process, especially if a large area needs to be protected.
[0023] Limited effectiveness: Sandbags are only effective up to a certain height, and if water levels rise above
that point, they may not be able to provide sufficient protection.
[0024] Leakage: Sandbags are not completely impermeable and can allow some water to seep through,
which may cause additional damage to the protected area.
[0025] Disposal: After the flood, the sandbags need to be disposed of, which can be another logistical
challenge.
[0026] Cost: The cost of purchasing sandbags and hiring labor to fill and stack them can be expensive,
especially for homeowners who need to protect a large area.
[0027] Overall, while sandbags can be a useful short-term solution for protecting a house
from floodwaters, they may not be the most effective or sustainable option in the
long term. There is a need in the market to provide this simple solution but in an
effective and affordable way.
[0028] Water-Filled Barriers: Water-filled barriers are inflatable tubes or bags that can be filled with water
to form a barrier around the house. They are lightweight and easy to install and can
be stored in a compact form when not in use. Water-filled barriers are effective against
low to moderate floodwaters and can be used in combination with sandbags for added
protection.
[0029] Metal Flood Barriers: Metal flood barriers are made of aluminum or steel and can be permanently installed
around the house. They are sturdy and durable and can provide excellent protection
against floodwaters. Metal flood barriers can be manually or automatically activated
and can be customized to fit the specific requirements of the house.
[0030] Removable Flood Walls: Removable flood walls are modular systems that can be quickly installed and removed
as needed. They are made of durable materials, such as aluminum or stainless steel,
and can provide excellent protection against high floodwaters. Removable flood walls
can be customized to fit the specific requirements of the house and can be stored
in a compact form when not in use.
[0031] Retractable Flood Barriers: Retractable flood barriers are permanent systems that can be easily deployed during
a flood. They are made of durable materials, such as aluminum or stainless steel,
and can provide excellent protection against high floodwaters. Retractable flood barriers
can be customized to fit the specific requirements of the house and can be easily
retracted when not in use.
[0032] Flood barriers are essential in protecting a house from floodwaters. Sandbags, water-filled
barriers, metal flood barriers, removable flood walls, and retractable flood barriers
are some of the most common types of flood barriers used to protect a house from floodwaters.
There is still a need in the market for a reliable, affordable flood barrier that
can effectively stop floodwaters and protect homes from its devastating effects.
[0033] Walls, levees, berms, and barricades are an effective way to prevent flood damage.
Also, by creating a "structural composite" system, the potential failure of walls,
levees, berms and barricades can be minimized.
SUMMARY OF THE INVENTION:
[0034] In a preferred embodiment, the present invention is referred to as a method for protecting
houses, buildings and structures from floodwaters using sandbags, comprising the steps
of:
- placing a sheet of laminate heat-shrinkable material covering the floor in front of
the entrance of a building that is to be protected from flood waters and over the
entrance of the aforementioned building so that said sheet covers not only said entrance
but also covers each sides of said building entrance to be protected from flood waters;
- arranging in rows one above the others a series of sandbags on the sheet of heat-shrinkable
material so that the entrance of the building to be protected from flood waters is
covered by the stacked sandbags;
- wrapping the bags of sand stacked in front of the entrance of the building to be protected
with the heat-shrinkable sheet;
- applying heat to the sheet of heat shrinkable material until the sheet shrinks over
the sandbags into a compact elongated unit;
- arranging the aforementioned elongated and compact unit against the entrance of the
building that is to be protected from flood waters.
[0035] It is an object of the present invention a method for protecting houses, buildings
and structures from floodwaters using sandbags, in which the heat-shrinkable material
may be one of polyolefin, fluoropolymer (such as FEP, PTFE or Kynar), PVC, neoprene,
silicone elastomer or Viton.
[0036] It is also an object of the present invention a method for protecting houses, buildings
and structures from floodwaters using sandbags, in which the heat applied to the heat-shrinkable
material may be a hot air blower.
[0037] It is also an object of the present invention a method for protecting houses, buildings
and structures from floodwaters using sandbags, in which the sheet of laminate heat-shrinkable
material protrudes at least two feet on each side of the entrance of the building
to be protected from flood waters.
[0038] It is also an object of the present invention an elongated waterproof device, capable
of being placed in front of the entrance of a building to be protected from flood
waters, comprising a set of piled sandbags wrapped around a sheet of laminate heat-shrinkable
material.
[0039] The usage of the present invention not only prevents the access of floodwaters into
houses and buildings, but it is also possible to help in deviating floodwaters, stabilizing
slopes, redirecting stormwater, and providing temporary access to flooded areas.
[0040] Since floodwaters may also be contaminated, it is important to prevent raw sewage
entering the sandbags contaminating the sand. The present invention minimizes exposure
to contaminants which may include sewage, petroleum, or other chemicals. If sandbags
are contaminated with petroleum, or other chemicals, they may need to be disposed,
as hazardous waste and laboratory testing may also be required. The laminate used
to wrap the sandbags up isolates them from the dangerous chemicals that may be present
in floodwaters, and they may be used again for other flood sites, minimizing the environmental
impact to the affected area.

DETAILED DESCRIPTION OF THE INVENTION:
[0042] The present invention is referred to a method for protecting houses, buildings and
structures from floodwaters using sandbags, comprising the steps of:
- placing a sheet 10 of laminate heat-shrinkable material covering the floor 12 in front
of the entrance 15 of a building 14 that is to be protected from flood waters and
over the entrance of the aforementioned building 14 so that said sheet 10 covers not
only said entrance 15 but also covers each side 17-18 of said building entrance 15
to be protected from flood waters;
- arranging in rows one above the others a series of sandbags 20 on the sheet 10 of
heat-shrinkable material so that the entrance 15 of the building 14 to be protected
from flood waters is covered by the stacked sandbags 20;
- wrapping the bags of sand 20 stacked in front of the entrance 15 of the building 14
to be protected with the heat-shrinkable sheet 10;
- applying heat to the sheet 10 of heat shrinkable material until the sheet 10 shrinks
over the sandbags 20 into a compact elongated unit 30;
- arranging the aforementioned elongated and compact unit 30 against entrance 15 of
building 10 that is to be protected from flood waters.
[0043] There are several portions for the above mentioned heat-shrinkable material 10, including
but not limiting to polyolefin, fluoropolymer (such as FEP, PTFE or Kynar), PVC, neoprene,
silicone elastomer, Viton.
[0044] The step of applying heat to the laminate material 10 wrapped around the sandbags
20 may be done using different devices. One example would be a hot air blower. As
it is illustrated in Figure 4, an operator 40 may manually apply heat air to the laminate
material 10 from the air blower 45 by passing the heat air nozzle 46 over the covered
sandbags 20. Heat 48 from the air blower 45 shrikes the laminate material 10 around
the sandbags 20 creating an elongated flexible unit 30 that can be placed in front
of the opening 15 to be protected from flood waters as it is shown in Figure 3. Figure
5 shows that the elongated unit 30 thus created may be bent as necessary and it behaves
as a unit.
[0045] As shown in Fig. 2 the sheet of laminate heat-shrinkable material 10 protrudes at
least two feet on each side of entrance 15 of building 14 to be protected from flood
waters.
