用内部排水管改造旧家庭的缺点(与外观)?

JGreenBuild|发布了General Questions

In a perfect world, an exterior footing drain and some sort of vapor barrier and/or gravel under the slab as well would be the solution to keeping a basement dry.

However, for those with older homes with neither… is an interior solution both sufficient and long term?

Obviously for surface water, grading and gutters is crucial but if you want to completely finish a basement, I expect it’s needed to manage the water effectively that does get to your foundation and footers. Heck, it seems important even if only for longevity of your foundation.

But is an interior solution enough? And what exactly is it intended to solve?

Are interior drains going to solve water on the outside of the foundation that manage their way from the surface soaking soil next to your foundation and even creating moisture/water within foundation (or even in your cinder blocks)? In that instance… wouldn’t the act of water pulling into your foundation, even if it is then kicked out via weep holes and a interior drain, deteriorate the foundation slowly?

Or is the above really not an issue if surface water is solved via gutters and grading?

Then interior drains are simply a solution for ground water rising up beneath the foundation both from outside and inside below slab. As this water rises, both an interior and exterior drain would do the same thing… no?

I really would like to understand the science behind these systems and what downsides I’m looking at with an interior system for older home. It just seems like disturbing the compacted soil around my home, landscaping, stoop, concrete path and driveway, etc… all is expensive, time consuming and might not be worth the extra effort.

But maybe it is… it’s hard to find the right information though.

    我认为这将取决于现场条件 - 例如,我的房子在山上,落水的岩石土。我有软管吹掉了我的喷射泵,它将全力泵入污垢的爬行空间几个小时,第二天没有证据。另一方面,我的妹妹有双油底壳泵,因为如果一个人失败,他们会洪水。

    You need to know the water table relative to your foundation ( all year. It will change) and how well the soil drains. If, for example, your house is sitting on a thick layer of gravel, a single point drain will make a lot more difference than if it is sitting on dense clay.

    至于它损坏了基础......我相信这不是理想的,但是,如果它不冻结,我认为我不会思考的水。不过,不是任何专家。

    J,
    问:“是一种内饰解决方案吗?”

    A. If you have an old house with water entry problems, finishing your basement is always risky. If you don't want to accept the risk, you should build an addition or a third story.

    如果您愿意在问题上抛出足够的资金,您可以接近防弹解决方案 - 但您可能不像产生的天花板高度,并且所有方法都存在一些风险。

    Redundancy can be provided by installing two sumps, each with its own sump pump (and battery backup for the sump pumps, of course).

    You can install dimple mat on the floor and walls, to provide channels allowing water to reach your new interior French drains.

    您可以在凹坑垫的内侧安装橡胶膜和一层刚性泡沫绝缘层。

    All of these details are good details -- not cheap, but high quality.

    正如我所说,仍有风险。有时地下室只是一个地下室 - 它并不注定是客厅或家庭影院。
