Installing French Drains for Surface Water

Rainwater and snowmelt can cause significant water damage to your home when they accumulate around your foundation. Installing French drains is a common solution for managing surface water and preventing this damage.

A French drain is a trench filled with gravel or crushed stone that is installed underground and slopes away from your home. As surface water enters the trench, it is absorbed by the gravel and carried away from the foundation.

Benefits of Installing French Drains

• Prevents water damage to your foundation
• Protects your landscaping from erosion
• Improves drainage around your home
• Reduces the risk of flooding

How to Install a French Drain

Installing a French drain is a complex process that is best left to a professional. However, here is a general overview of the steps involved:

1. Dig a trench around your home’s foundation that is at least 12 inches wide and 24 inches deep.
2. Line the trench with a filter fabric to prevent soil from clogging the drain.
3. Fill the trench with gravel or crushed stone.
4. Install a drain pipe at the bottom of the trench and connect it to a storm drain or other discharge point.
5. Backfill the trench with soil and compact it.

Maintenance of French Drains

French drains require regular maintenance to ensure they are working properly. This includes:

• Cleaning the drain pipe of debris
• Inspecting the filter fabric for tears or holes
• Adding gravel or crushed stone to the trench as needed

By following these tips, you can help your French drain perform optimally for many years to come.
