Water is one of the most powerful forces on Earth. One inch of rain equals 27,000 gallons of water per acre. Once water enters the basement, chances are that it will occur again. It is also likely that it will continue to get worse. Water has a memory. It will follow the same path each time your basement leaks, thereby creating a larger path. Most homes are built with some sort of waterproofing. Here are some common reasons why basements leak:
False Water Tables
A False Water Table was created when your basement was built. The first step in building your basement was to dig a large hole. The earth surrounding this large hole is soil compacted by millions of years, also referred to as "Hard Pan." The earth being removed from this hole will never be as compact when it is put back. This is referred to as "Soft Pan." When it rains, or when snow melts, the water will follow the path of least resistance. Thus, water flows from Hard Pan to Soft Pan and creates a false water table. As water continues to fill the false water table, some of the water will begin to flow (through gravity and pressure) to the real water table. However, water hat has accumulated around the false water table will continue to rise when either the water is coming in too fast, or the real water table is full and cannot handle the volume of water any longer. As the water fills all pockets and voids it will continue to rise until it reaches the floor. Then it will fill the voids and pockets above the floor level and against the walls. A false water table is created around all houses and buildings even if they are built on high ground or a hill.
Hydrostatic Pressure is the pressure caused by water seeking its own level. Once the false water table fills up and becomes higher than the floor, Hydrostatic Pressure is created. Water pressure is 63.4 pounds per cubic foot in all directions. The reason it sometimes takes a heavy rain for water to actually become visible is because the cavity under the basement floor can hold up to 2500 gallons of water. When Hydrostatic Pressure occurs, water seeks the path of least resistance. This could be cracks in the floor, cracks in the walls, key ways or cove areas (where the floor and the wall join together).
NOTE: Once Hydrostatic Pressure causes seepage, the problem can only be solved by a system designed to relieve pressure and control the water. Excavation and do-it-yourself methods can not and will not solve the problem. Water rises equally on all four sides and will seek the path of least resistance into your basement (most often, the cove area).
Seam Infiltration happens when basement walls are poured after the footers have already cured. The result is a less than 100% bond between the new walls and cured footer. Water, under extreme hydtostatic pressure can open up this vulnerable seam known as the key way or cove area. Constant water pressure will continue to make the opening wider and wider. Example: If you have ever tried to patch a crack in cement, you know from experience that it will eventually reappear. It is impossible to seal a crack because the old cement is dry and the molecules are solid.
As the earth around the foundation settles, the movement may cause the walls to shift, causing minor settlement cracks. Normal settlement takes one to seven years on new homes. However, if you have water seepage, settlement will continue until you control the water. Settlement problems will only get worse if the water table is not controlled.
While water seepage is occurring, water is traveling from a point outside your basement to a point inside you basement. This is causing erosion to occur, which will undermine the footer. Continued erosion will cause the footer to crack and the house to shift. Once the house starts to shift, structural damage to other areas of the home are inevitable, such as:
