Basement flooding happens when water because of heavy rains and other many reasons enter the basement of your property and stagnate there as water has no way to withdraw from the basement. If stagnated and remained for a long time inside the basement the water consequently damages building and starts smelling.
Causes of Basement Flooding
Anytime flooding of basements can happen. If never happened before it can happen to you or anyone else who has a basement. It is common that flooding happens during monsoon and big rains and massive and rapid snowmelts in the summer and spring respectively, but keep in mind that it sometimes happens in dry weather too.
There are many causes behind the happening of basement floods. Flooding can happen by oozing or flow through the walls or foundations floor, by sanitary or storm sewer backup and from surface water sources. Keep in mind that inherently basements tend to or they are prone to flooding. By definition, they are a lowest level of a building usually built partly or entirely below ground level. There exists natural ground water below the ground surface. The level of ground water at some specific time can be above the level of basement floor. While in some places the level of ground water is all time above the level of the floor.
It is gravity which moves water from higher level to lower level. If any of the sewer level or ground water level around your home is above the basement floor, the water will likely be moved into your property’s basement by gravitational forces. For example, a fissure in the base floor provides gravity with a perfect path for water to be sucked into the basement. By structure and design sanitary sewers always have a route to the home and it is called sanitary sewer lateral. Under normal circumstances the lateral permits water to flow from your home to the sewer, there is possibility for water to move towards your home from the sewer.
Poor lot levelling: the sloping of the land is causing water flow toward your property
Poorly structured and unmaintained base: fissure in the base have developed that permit water to ooze in
Problems with drainage pipes: both of the lateral and weeping have problems
Unsatisfactory and poor basement sealing
When you intend to build a home or any other building always make sure that the basement tile and foundation are sealed properly. Water will start to ooze from the ground into your property basement if this is not done correctly and with care. This may be one of the reasons if your property basement floods during all or most rainstorms.
Weeping tile failure
Every building is supposed to have a sewerage system built around the structure to help ensure that water moves from building and does not ooze into. If this structure, also famous as weeping tiles has been fitted not correctly or fails, the basement may confront flooding specifically during monsoon season. To know that if this is the problem to basement flooding you need to have inspected it by an expert.
Sewer or gutter are important as they help in moving water away from building and keep basement dry. Gutter blocked with leaves, twigs, seed pods and other junk stop and prevent pouring and withdrawal of water from gutter and will force water down around the building where it can pool, stagnate and ooze into the basement.
Damaged pipes, sucking pump and hot water tanks
There are three possible sources to your house’s basement flooding: sucking pump, hot water tank and damaged pipe. If damage is happened to or any one of these is broken your house’s basement will probably flood. Intense temperature if hot causes pipes to expand if cold causes them freeze and contract and finally creates fissure in and break or burst them, poor and unskilled workmanship and the pipe age, these are the reasons pipes fail. Sucking pump and water tank are supposed to check annually for faulty parts.
Other probable reason for basement flooding include levelling around your home and savage backup. Levelling slope supposed to have away from the home structure so that the risk of basement flooding is rare.
Wrongly fitted downspout
The function of downspouts is to lead water away from the building and its base. They are supposed to away from the basement wall at least 1.5 to 2 meters and drain away from the home usually towards the backyard or street. If your property’s downspouts are damaged or broken, water will stagnate and pool and can ooze gradually into basement base through the cracks.
Basement Flooding Solution
Make the walls water proof
Fitting an internal drainage system remove the water out but does not waterproof the wall. For that purpose you need to build external drainage system: a French system to remove hydrostatic pressure and exterior waterproofing to preserve and protect base of the basement.
Pump out the water
If you are unable to remove the subsurface water out, the remaining option is that you will have to channel it out from inside. For creating an interior drain system you will have to see a channel around the perimeter of the floor, break out the concrete and lay pierced pipe in the hole. The pipe drains into a collection tank at the basement’s low place, where a sucking pump shoots it out the house.
Set up a curtain drain
If you don’t possess working footing drains, set a curtain drain to direct other way the water that’s coming towards your house. Like a French drain a curtain drain is a hollow ditch 2 feet deep and 1.6 feet across filled with gravel and pierced piping that stops water uphill of your house and carries it down the slope safe distance away.
Stopple the gap
If you observe water dripping in to the basement fissure or gaps around plumbing pipes, you can plug or stopple the cracks and openings yourself with hydraulic cement or polyurethane caulk for less than $20.
