Groundwater Pressure and Seepage
Groundwater pressure and seepage in an open system can be a major cause of property damage, especially when an extensive well field is adjacent to a structure, such as a home, office building, or warehouse. Understanding how water pressure and seepage can affect buildings requires knowledge of many different aspects of hydrology, hydrogeology, and engineering principles.
When there is an open system in place, it means that groundwater pressure is not regulated by any walls or barriers. Water pressure builds up above a property due to the presence of a high-pressure well field, which can cause seepage in otherwise solid buildings and foundations. Seepage can lead to damage of the foundations, walls, and other structures, as well as increased moisture levels in interior rooms and basements if the water is not properly managed.
In order for water pressure and seepage to be a problem, there must be a difference between the water pressure present in the well field and the water pressure present in the building. On a basic level, the water pressure in the well field will typically be higher than the water pressure in the building. Under this condition, water will move from the well field to the building. In essence, the water pressure in the well field is pushing the water into the building.
If this happens, the foundation, walls, and other building materials become vulnerable to water damage. In addition to potential damage to the building, water pressure can also cause a fluctuation in the rate of seepage which can lead to pooling of water around the foundation and the eventual weakening of the soil around the foundation of the structure.
It is important for property owners to understand that groundwater pressure and seepage can not only lead to physical damage to a structure, but also increase moisture levels. Moisture from seepage can lead to an increased humidity level, which can create an uncomfortable environment and an increased risk of mold development inside the building.
When dealing with groundwater pressure and seepage issues, the best solution is typically preventative. Property owners should make sure that any high-pressure wells adjacent to their property are appropriately managed. Additionally, property owners can consider solutions such as installing a sump pump, lining the foundation perimeter with a waterproof membrane, or employing water removal and treatment systems to keep water away from the building.
It is also important for property owners to understand the underlying science behind groundwater pressure and seepage in order to be able to identify possible solutions. Understanding the basics of hydrology, hydrogeology, and engineering will help property owners understand the problem and take the necessary steps to prevent seepage, property damage, and health risks caused by moisture.
