Bowed Wall Repair Pros Share Why Homeowners Worry About Hydrostatic Pressure
There are two words whose very utterance is apt to make homeowners’ brows furrow with worry. Do you know what they are? We do. It’s hydrostatic pressure and with good reason. Hydrostatic pressure is one of the chief reasons why buildings end up with bowed walls. Here’s a look at why the pressure builds and how it always leads to the need for bowed wall repair:
To understand the concept of hydrostatic pressure, think about two, equal size buckets of dirt placed onto a balancing scale. They will initially each weigh the same amount. However, if the dirt in one of the buckets becomes wet, it will grow heavier and tip the scales in one direction. Well, hydrostatic pressure operates in much the same way.
The ground water may come from any number of sources including atmospheric precipitation, normal condensation, household runoff (e.g. grey water) and an area’s inherent water table. As it wets the dirt around the foundation wall and continues to increase in volume, it presses up against the wall’s surface with tremendous, lateral force. Over time, those impressive lateral forces cause the foundation’s materials to develop hairline cracks and weaken in spots. Those weak spots, as a result of ongoing pressure, will eventually cave inward and create bowed walls.
Fortunately, hydrostatic pressure may be reduced in several different ways. For example, soils that are naturally heavy and porous (e.g. clay) may need to be dug up and replaced. The built-up ground water will also need to be removed and a diversion system must be put into place. Repairing the existing bowed walls and applying waterproof sealant will help lessen the amount of hydrostatic pressure on a home’s foundation as well.
