What causes a flooded basement?
Flooding of basements can occur whenever. It can take place to anyone who has a basement, even if never flooded before. While usually, flooding occurs throughout huge rains or fast snowmelts in the spring, it can take place even throughout dry weather.
There are several reasons that basements flood. Flooding can take place by seepage or flow through the walls or structure floor, from surface water sources, or by a hygienic or storm sewage system backup. Please remember:
Basements are naturally prone to flooding. They are, by definition, the lowest level of a structure, typically built partly or totally below ground level.
Groundwater is water that is naturally situated below the ground’s surface. The groundwater level can be, at times, above the level of the basement floor. In some areas, groundwater can be above the level of the floor at all times.
Sewers are likewise found in the ground. This consists of all ranges- storm, sanitary, and combined. While in many cases, sewers are below the level of the basement, the water level in the drains can be, sometimes, above the level of the basement flooring.
If either the groundwater level or sewer level around your home is above the basement flooring, gravity will try to move that water into your basement. While under typical conditions, the lateral allows water to stream from your home to the sewer, water can move from the sewage system towards your home.
All basements are prone to flooding and there can be several causes behind the water in your basement.
Below are a few of the most typical reasons for a flooded basement
Pipes leaks
This could be a burst or dripping pipeline, a leaking waste line, a broken supply tube for your washing machine, or a leaking water tank or water heater.
Leaky basement windows
If your window wells fill with water (from a flooded backyard or stopped up seamless gutters), don’t be shocked if water leakages into the basement through and around the windows.
Leaky basement structure
This is by far the most typical cause of basement flooding. Extreme amounts of rain, bad backyard drainage, and sewer backups are common offenders behind a leaking foundation.
To understand why a basement might flood, it is very important to reveal the more common pathways, that authorization water to flow into or around your basement. Some of these problems consist of:
1. Poor lot grading: the sloping of the land is promoting water flow towards your home
2. Unmaintained foundation: cracks have developed that permit water to leak in
3. Issues with pipelines: both the weeping tile and laterals have problems.
The figure highlights common problems (in red) that all might contribute to a higher risk of flooding.
Flooding during dry weather
Many flood occasions do occur during wet weather, but a flood can take place throughout dry weather conditions too. 3 of the most common reasons are as follows:
– An obstructed or failed hygienic lateral. The sanitary sewer lateral, much like the shingles on your roofing system, or your paved driveway, is a feature that will break down in time. As a lateral degrades, numerous things can occur. Tree roots may permeate and the lateral may collapse because of gradual deterioration. These situations can block the lateral, leading to a sewage backup.
In this case, it will be your own home’s domestic wastewater that floods your basement. The only way for the wastewater to drain becomes the lowest component in the home– typically the floor drain or a basement level shower stall, sink or toilet. Your lateral, similar to your roofing, your driveway or windows, requires upkeep and ultimately requires to be changed or restored. Speak with certified plumbing, who can carry out an assessment.
– Another factor for the clog of a hygienic sewer is simply due to what is being flushed down the toilet. Our Toilets and Drain page has a list of things not to put down your drain, or flush down your toilet. Toilets are for human waste and toilet tissue, and that is pretty much it!
Foundation drainage failure. Subdivisions are sometimes constructed in lower-lying areas that are generally wetter than others. In such cases, the structure drainage system, whether by gravity or by the pump, must work constantly to keep the groundwater level around the structure lower than the basement flooring.
Just as with drain laterals, gravity structure systems, often called weeping tiles, may degrade in time or get plugged by fine sediments. As a result, the ground around the foundation will cease to drain itself by gravity.
These devices pump out the water around the foundation and either discharge it to the yard, storm drain, or illegally to the sanitary sewage system. These pumps can stop working, or just be unable to keep up with the incoming water or get plugged.
– Water supply-line break or hot-water tank failure. In some cases, a flood is because of a break in the home’s internal water supply plumbing or failure of the hot-water tank. This can arise from aging pipes or devices, a leak of a pipe during building and construction, or freezing-induced splitting of a pipe.
Flooding throughout damp weather
Flooding during wet weather conditions is far more typical than flooding throughout dry-weather. Rain, ground-thaw, and snowmelt put a heavy load on drainage systems, including the storm and sanitary sewers discovered underground. With the additional water on the surface and underground, there are several reasons that a basement might flood.
During periods of heavy rain or rapid snowmelt, surface area water might pool around the house, or accumulate in hard surface depressions such as driveways or roads surrounding to a home. During severe weather conditions events, this water can stream into the home.
– Foundation drain failure. Houses generally have some form of a drainage system built around them. This protects promotes the movement of water far from the basement and obstructs the entry of water into the structure.
