I need help with standing water under our house, the soil is uneven. It leads to indoor humidity problems.?

Question

It also worsens the ongoing termite problem. We have plenty of ventilation but when it rains it pools there and we have mold on the windows and nothing seems to dry.

Answer 1

You could find a low spot and install a sump pump to move water away from house.

Answer 2

Try making or adding a french drain to lead the water away from the house.

Good drainage is important to ensure that a home stays dry and free of mold. If groundwater collects in the basement, it is not only an inconvenient eyesore for the homeowner, it can also lead to wood rot and mold.

The most reliable way to eliminate undesirable, free standing water is to install French drains with slotted pipes, filter fabric and gravel. The old way of installing French drains is to do it without the gravel and the fabric. Without the gravel and the fabric, however, the drain can clog up with sand and soil over time.

The "best practice" for installing French drains is to use perforated drainage pipes, which allow water to enter or exit through small openings along the pipe. The perforations can be circles or slots. But slotted pipes are better than pipes with small round holes because they tend to reduce the amount of fine soil particles that get into the pipe.

Here's how to do it:


Dig a trench along the outside of your footing. The trench should be at least two feet wide, and can be as deep as six feet for a basement or as shallow as two feet for a slab-on-grade home.

Lay the pipe on the virgin soil. It is very important that the pipe always be sloped from a higher starting point to an ending point of lower elevation, so gravity can force the water out. The grade should always slope away from the home to ensure that the water is directed away from the walls of the home.

Cover the pipe with at least 12 inches of washed gravel.

Lay filter fabric over the gravel to prevent any soil from clogging the pipe.

Back fill the foundation with top soil back to its original grade height.

It's easier than you think. My mom did one on her own.

Answer 3

You could also try adding more dirt around the outside of the foundation so the water runs away from the house before it has a chance to get underneath

Answer 4

I do computer work for a company here in CT called Neutocrete. They have a web site called www.neutocrete.com. I am not sure what the cost is but it is really the only solution unless you can somehow seal up the crawlspace from the outside.

Answer 5

Depending on the scape of the land, you can either dig trenches from the low areas where the water stands to allow is to drain out........OR......... build up the low areas where the water sits with either dirt, sand, or gravel. Take your pick.
