What Is A French Drain?

Essential components of both interior and exterior waterproofing solutions, French drains are composed of weeping tile that run through underground trenches collecting excess water and moving it away from your property. Once the trenches are dug and the weeping tile is installed, they are then covered with a layer of gravel to assist with water drainage, before being sealed with either soil or concrete.

There are two main types of French drain systems:

  1. Interior French Drains: Installed as part of a wider interior waterproofing strategy, interior French drains are installed around the perimeter of your basement. They collect excess water inside your basement and chanell it towards your new sump pump.
  2. Exterior French Drains: Installed either as part of a wider exterior waterproofing strategy or as a stand alone solution for water pooling in your yard. Exterior French drains are installed at the problem area of your yard, they allow excess water to seep into the weeping tile to be channeled away from your home.

At DGI Waterproofing, we install both interior and exterior French drains. Book your FREE at-home consultation to assess your needs and install the best waterproofing solution for your property.

French Drain Repairs

The nature of French drains means there are very little repair requirements, however, this doesn’t mean they never happen! If you start to notice damp areas in your basement, or water pooling in your yard then give our us a call for same-day repairs for French drains.

Some common French drain repairs include:

  • Collapsed sections: Heavy loads or shifting soil could crush part of your drain, preventing water to effectively drain through causing water pooling. This is more common for exterior drains.
  • Poor installation: Incorrect slopes, low-quality materials or wrong installation might cause your French drainage system to not function as it should.
  • Clogged pipes: Over time debris, such as excess soil, leaves and other organic materials might clog your pipes, preventing water to effectively drain through.
  • Cracked pipes: Soil erosion, excess weight or general wear and tear might cause you weeping tile pipes to crack, allowing water to exit the drainage system and seep into your yard, potentially causing water pooling.

French Drain Maintenance

French drains require very little maintenance, this is one of the most appealing things about them – once installed they will work their magic with little or no further services.

Included in our French Drain maintenance services are the following:

  • Pip cleaning: Our contractors will use specialized equipment to check and remove any debris that might be clogging your system.
  • Check for cracks & weak points: We will check the weeping tile to ensure there are no major or minor cracks, replacing any areas were we notice weak areas.
  • Full waterproofing system check: If you have a French drain as part of a wide waterproofing system, it is a good idea for us to check the complete system to make sure everything is working properly.

French Drain FAQs

A French drain is a trench filled with gravel or rock containing a perforated pipe that redirects surface and groundwater away from an area. The system works by allowing water to flow through the gravel into the perforated pipe, which then channels it away from the property to a safe drainage location. This helps prevent water accumulation around foundations, basements, and other areas prone to flooding.

You might need a French drain if you notice persistent water pooling around your property, damp or wet basements, or signs of water damage on your foundation. Poor drainage can lead to significant issues like mold growth, structural damage, and erosion. A professional assessment can help determine if a French drain is the right solution for your drainage problems.

Yes, a French drain can be installed in an existing landscape. The installation process involves digging a trench, placing the drainage pipe, and backfilling with gravel and soil. Careful planning and professional installation ensure minimal disruption to your landscape and effective water management. Our team at DGI Waterproofing takes special care to preserve the aesthetics of your property during the installation process.

The installation time for a French drain depends on several factors, including the size of the area, the complexity of the drainage issue, and soil conditions. Typically, a standard French drain installation can take anywhere from a few days to a week. Our team works efficiently to complete the installation promptly while ensuring high-quality workmanship.

Regular maintenance is essential to ensure your French drain functions effectively. We recommend scheduling a professional inspection and cleaning at least once a year. This helps identify and address any potential clogs or damages early, ensuring the system remains efficient. Additionally, after heavy rains or storms, it’s a good idea to check the drain for any debris or blockages.

Common problems with French drains include clogged pipes, collapsed sections, and improper installation. Clogged pipes can be cleared by removing debris and performing regular maintenance. Collapsed sections may require pipe replacement and reinforcement of the surrounding soil. Improper installation issues, such as incorrect slopes or inadequate materials, can be corrected by re-evaluating and re-installing the drain system properly. At DGI Waterproofing, we provide comprehensive repair services to address all these issues and ensure your French drain system operates optimally.
