Negative And Positive Pressure Waterproofing Basics For Basements

Negative And Positive Pressure Waterproofing Basics For Basements

Whether because of an older foundation that has seen better days or local conditions that cannot be accommodated in other ways, sealing a basement often turns out to be a helpful addition to a home. For a home with a basement that remains unfinished, even the slightest prospect of a leak can put off plans for turning the space into something more useful and enjoyable. In many other cases, regular basement leaks contribute to troubles and difficulties of other definite kinds, from mildew to increased dangers of further structural damage.

While the subject is a little more complex than many would initially assume, understanding the basic is not normally difficult. Basement waterproofing info that covers the key points can help homeowners make the best possible decisions for their own situations.



One of the most important things to understand is that there are two basic approaches to waterproofing. Basement waterproofing info will sometimes gloss over this fact, and this can easily lead to confusion. Most experienced providers, however, will recognize the fundamental importance of this distinction and try to make sure that their clients appreciate it before pushing forward.



That division also turns out to be relatively simple to understand. Every movement of water is motivated by some combination of a couple of basic forces, with gravity being the one of the pair with which everyone is more familiar. In addition to the unavoidable, constant pull of gravity exists the occasional, contextual possibility that pressure will force moisture to move in a certain direction. When water builds up in the soil that lies against a home's foundation, for example, an excess of pressure will encourage it to find its way in.



Basement waterproofing info that delves into this issue will generally divide this latter point into two separate aspects. When pressure is trying to move water away from a given space, that location is normally characterized as one where positive amounts obtain. Any space into which that moisture might be pushed, on the other hand, will be labeled as one of "negative pressure," with the intended image being one of something like a vacuum drawing water in.



Why this distinction matters in practice is that waterproofing can be applied in either domain or in both simultaneously. Because of the distinct nature of the issues involved in each case, entirely different approaches will typically be indicated in each. A membrane-based waterproofing solution that might work well in an environment with positive pressure, for example, could come up short in another. Waterproofing providers will typically walk their clients through such issues.
