我如何確定我的地下室洩漏是否是基礎問題


4

在非常大的降雨或大量積雪融化之後,我平均每兩年發生一次地下室滲漏。它僅發生在地下室的一堵牆上,我從那堵牆的相對兩端發現地板上有水。這使我相信這是基礎牆。

幾年前,我有人進來從內部打開石膏板,他說他找不到洩漏。然後,他將洩漏歸因於一個舊窗戶,並責令我更換它,以及他撕掉的干牆。幾年後又一次洩漏,我知道這不是窗戶。

我已經連續數年更換了那堵牆外面的剝落/開裂磚,並且有一條水泥人行道直抵整面牆,中間沒有間隔物。我還注意到地下室窗戶外面的綠色黴菌,地下室窗戶低於地面。

聽起來像是地基漏水了嗎?如果是這樣,這是昂貴的維修嗎?這房子只有30年的歷史。是什麼會導致這種故障這麼快?

It's nearly impossible for us to diagnose this without being there in person, but typically wet basements are caused by ground water--rather than a leaky window or the like.

The ground water needs to go somewhere. If the soil can't drain, it builds up pressure and looks for a way into your basement--either via the walls or, more often, where the wall connects to the footer at the floor.

Cheaper/easier things to try first:

  • Add/fix gutters and downspouts
  • run downspouts further away from house
  • properly slope the ground away from the foundation around the house.
  • install surface drains (such as a dry river bed)
  • have gutters/surface drains go to dry wells

More expensive/complex solutions:

  • Install internal footer french drains and a sump pump
  • dig down exterior to install exterior footer french drains and waterproof exterior

Fixing gutters and such is fairly inexpensive and a weekend project. Sloping the yard and surface drains are a bit more work, but still in the realm of DIY.

Installing footer drains and waterproofing the exterior below grade, however, is not a DIY project and will cost quite a bit.
