请看以下两个图,几个出租房地基附近有水土流失造成地基外露。地基附近地面有的平坦,有的是小斜坡。造成这个问题的原因,有的是因为gutter and downspout extension 的问题;有的是房子建在有点坡度的地上;并且地基附近地面裸露,没有草或其它植被覆盖。现在gutter and downspout都修好了,downspout extension也计划装上4~8尺长。
When it is raining, go outside to see why there is flowing water near your foundation. There should be NO water near your foundation when it is raining, because your rain gutter and downspouts should direct water far away from foudation as possible.
Like in your first picture, the downspout just dump the water near corner of the house, that's not enough, you need to add pipes to direct water away from the foundation. The rain pipe could be exposed on ground, or for aethetics, bury such pipes in the ground and it is not uncommon such pipes runs 10-20 yards away from the house.
In your case, hire a drainage specialist to do an estimate of backfilling dirt around foundation, and make some modification to your gutter system to direct rain water away. It is not high tech and mainly need knowledge and muscle.
Usually they put some wooden frame above ground to make concrete pretty, and the underground portion of the concrete pour would be irregular limited by just the trentch they dug. You can see the dirt is washed away to expose the irregular concrete below the framed portion. You need to backfill until the irregular concrete is invisible.

现在还计划做, 1. 在地基附近加土并压实一些。2。在地基附近加上rubber mulch 或gravel (小石子), 这个是optional. 请有类似经验的地主,分享一下经验好吗?1. 加土就行了嘛?还是最好再加mulch or gravel? 2. 是rubber mulch 还是小石子好? 自己做了一些研究,rubber mulch 40% 更贵,warranty 10年,安装方便。小石子便宜一些,基本上一劳永逸,安装重一些。不想用wood mulch, 因为只能坚持一年。谢谢When it is raining, go outside to see why there is flowing water near your foundation.
