How to Fix High Water Table Under House

There are several ways to fix a high water table under your house. The best solution depends on the severity of the problem and the underlying cause. Here are some of the most effective methods:

2. Line the trench with landscape fabric
3. Add a layer of gravel to the bottom of the trench
4. Place the perforated pipe on top of the gravel
