Hydrostatic Pressure

By now you must have heard about how wetness can seep in through solid walls. Called hydrostatic pressure, it is a kind of pressure that water seems to have even when not compressed or forced through a porous surface. However, not all forms of wetness is a result of hydrostatic pressure. There are certain conditions that have to be fulfilled for it to work.

It makes sense to know the difference between hydrostatic pressure and other forms of water seepage. Apart from having an accurate knowledge, it makes the diagnoses and the remedial measures easier and a lot more effective. Either way, you should get a full course basement waterproofing done as a preventive measure.

The ideal amount of wetness is no wetness at all

Unless you already have a full course basement waterproofing done, your walls, especially the ones below ground, are never truly safe from getting wet. While that may not sound like too much of a big deal, you have to know that over time, wet walls, including concrete and masonry walls will get damaged over time. Apart from the moisture leading way for all kinds of growth and bad smells, the added weight to the structure can also cause significant damage in the long term.

How is the water getting in?

Hydrostatic pressure is the pressure that standing water creates on the surfaces it comes to contact with. Think of a bucket with a small hole on the side. It will eventually empty itself out till the water level reaches the hole. It can be slow, but it will surely happen. Concrete and masonry walls go through the same thing and if there is water in contact with the wall, it will seep through.

Not every case of water seepage or moisture in your walls is a result of hydrostatic pressure. Above ground seepage is usually not caused by hydrostatic pressure. Wetness in your walls could be coming from various other sources, so it is important that you find the actual cause of your moisture for it just may not be hydrostatic in nature.

For moisture to be caused by pressure there must be a source of standing water, or the structure must be in the way of a water flow. Make sure your basement waterproofing is done thoroughly to avoid any kind of moisture seeping in, either through hydrostatic pressure or otherwise.
