A common problem that homes built on hillsides have is that when it rains the water comes down the slope and rests against the foundation of the home. The hydrostatic pressure of the water will often typically eat away at the concrete and stone foundation of the house. The breakdown of the foundation will allow water to leak in to the basement and create a flood every time it rains hard. Here is how you can put in a French drain around the basement of your home to protect the foundation and prevent basement flooding.
You Will Need:
- Small Backhoe
- Filtration Fabric
- Perforated PVC Piping
Digging the Trench
You need to dig a trench down to the bottom of the foundation starting on the back of the house facing the slope of the hill and along the sides of the home sloping towards the front of the house. The trench should be at least 4 or 5 feet away from the house to prevent the water from building up alongside the foundation when it filters into the drain. You should also make the trench wide enough so you have room to work in it while installing the permeable film, stone, and PVC piping. The trench should be extended out into the front of the house to connect the two sides of the French drain together so the water drains into a drainage area without eroding your front lawn.
Installing the French Drain
You first want to lay down the filtration fabric. The fabric should be wide enough so that once the stone and pipes are installed, you can wrap the fabric around the top of the French drain to prevent dirt and small stones from getting into the perforated pipe and clogging it up.
After you have laid down the fabric, you should lay down 4 to 5 inches of gravel over the fabric all along the bottom of the trench. You then will put down the perforated pipes – making sure the holes on the pipes are facing downward against the gravel. Connect the pipes together before you place another 4 to 6 inches of gravel into the trench to cover the pipes. You will then fold the fabric over so it completely covers the stone and pipes.
After you have completed these steps all around your home, you will want to replace the dirt you dug out of the trench to make the area safe to walk over.
