Why Basements Leak Water?

It is very important to be educated on why your basement is allowing the presence of water leaks. If you know why, fixing the problem becomes very easy.
The reasons for basement leaks are as follows:

1. Top of the Wall Leak – A leak over the top of your foundation/basement wall when the ground is near level, or worse, sloping into the house. If rainwater is draining back towards your house, rather than away from it, this happens. It is an older construction model problem which used archaic drainage and gutter technology. Also, the soil under older home may be settled more over time compared to the surrounding, undisturbed soil. As this soil settles, it creates low spots where water can then drain into the basement.
2. Window Wells Leak – A leak that happens via the low lying basement windows which generally keep groundwater and soil away but due to drainage issues, water tends to seep in. Overflowing or blocked gutters cause a lot of problems in the window wells.
3. Wall Cracks Leak – Cracks are a very serious problem for leaks and otherwise. Just fixing a crack doesn’t deal with the problem – figuring out the underlying cause of the cracks do. Mostly cracks are created by pressure generated via water flows and drains. The pressure can build up so much that it can create multiple cracks, erosion of the foundation and even a complete structural failure of your home.
4. Tie Rod Holes – Rods placed into the ground during the construction of one’s house to form work platforms, once removed leaves rod holes. These holes cause leaks in older homes.
5. Honeycomb Leak – Air pockets that look like honeycombs due to improperly mixed concrete form cavities which water can easily compromise causing leakage. You can easily seal them.
The reasons for basement leaks are as follows:
6. Sewer Pipe Leak – These are noticeable only when the issue becomes more serious and noticeable i.e. when a pipe leaks eventually bursting open. The wastewater leaks will cause staining and mold.
7. Mortar Joint Leak – Mortars are constructed for homes that have basement walls constructed of cinder block, brick, stone or wood rather than concrete. When it deteriorates, it becomes less water-resistant, allowing water to slowly make its way through the mortar and into your basement through the open joints between the top of the block wall and the blocks themselves.
8. Water Pipes Conduits Leak – A hole in a concrete foundation is a potential source for water leak. This hole, after construction, is sealed with a water plug, made from a cement material on the inside and outside. Any time water is being collected, there’s an opportunity for a leak.
9. Floor Cracks – Hydrostatic pressure or water pressure has a natural effect on your home mainly due to the weight of water in the ground. When your house settles over time, hydrostatic pressure, caused by poor drainage, clay soil, underground water sources and extreme weather, pushes pressure against your basement foundation. This will cause water to collect and build up around your foundation. The more weight this water carries, and the higher the pressure. Humidity in the basement also causes its own set of problems like mold, mildew, dust mites and an inflated energy bills – all things that are damaging to the health of your walls and family.
10. Floor Drain Clog – When the floor drains clog, this leak happens. Water from a clog in your home’s sewer line or even the municipal sewer line can cause sewer systems to back up into your home’s drain system, resulting in water coming up through sink drains and floor drains in the lower levels of your home.
The reasons for basement leaks are as follows:
11. Floor & Wall Joint Leak – The process of digging and pouring your basement foundation and walls results in an unsecured bond between the footing of your basement and the basement walls. The new concrete will not bond to the previously poured and already dried concrete. This space in the floor and wall joint will allow for water to pass through under pressure.
12. Plugged Drain Tile – The drain tile, which wraps around the perimeter of your basement, is made from perforated plastic piping which is wrapped in a cloth sock. This sometimes leads to the drain tile leading to leaks.
