What Is A Curtain Drain?

Are you curious to know what is a curtain drain? You have come to the right place as I am going to tell you everything about a curtain drain in a very simple explanation. Without further discussion let’s begin to know what is a curtain drain?

Dealing with excessive water runoff around your property can be a challenging and frustrating issue. One solution that has proven effective in managing water drainage is the installation of a curtain drain. If you’ve ever wondered what a curtain drain is and how it works, you’re in the right place. In this blog post, we will explore the concept of curtain drains, their purpose, installation process, and the benefits they offer in managing water flow.

What Is A Curtain Drain?

A curtain drain, also known as a French drain, is a type of subsurface drainage system designed to redirect and manage water runoff. Its primary purpose is to alleviate water accumulation and prevent the saturation of soil, which can lead to foundation damage, erosion, and other water-related issues around properties.

Construction And Installation:

Curtain drains consist of a trench filled with a combination of gravel or aggregate and a perforated pipe. The trench is typically excavated in a sloping or horizontal manner, strategically placed to intercept and divert water away from problem areas. The perforated pipe allows water to enter the drain while preventing debris and sediment from clogging the system.

During installation, the trench is lined with a geotextile fabric to prevent the infiltration of soil and sediment into the drainage system. The fabric acts as a filter, allowing water to pass through while preventing the accumulation of fine particles that could impede the drain’s functionality.

Water Diversion And Drainage:

Curtain drains work on the principle of gravity, efficiently diverting water away from areas prone to water accumulation. As water flows through the surrounding soil, it enters the perforated pipe and travels along the drain, eventually being directed to a suitable drainage outlet. This process effectively manages water runoff, preventing it from pooling around foundations, basements, or other vulnerable areas.

Benefits Of Curtain Drains:

  1. Water Management: One of the primary benefits of curtain drains is their ability to effectively manage water runoff. By redirecting water away from critical areas, they help prevent water damage, soil erosion, and potential foundation issues.
  2. Foundation Protection: Excessive water accumulation around foundations can cause soil saturation and lead to structural damage. Curtain drains help protect foundations by keeping the soil around them adequately drained and stable.
  3. Landscape Preservation: Curtain drains can also help preserve the integrity of your landscape by preventing erosion and waterlogged areas. By efficiently managing water runoff, they allow you to maintain a healthier and more aesthetically pleasing outdoor environment.
  4. Versatility: Curtain drains can be installed in various locations, including residential, commercial, and agricultural properties. They are versatile in managing water runoff from heavy rainfalls, sloping landscapes, or areas with high water tables.

Professional Installation:

While it may be tempting to install a curtain drain as a DIY project, it is generally recommended to hire professionals for the job. Experienced contractors have the necessary expertise to assess the drainage needs of your property, determine the ideal placement and slope of the drain, and ensure proper installation and functionality.


Curtain drains are an effective solution for managing water runoff and preventing potential damage caused by excessive moisture. By diverting water away from critical areas, these drainage systems help protect foundations, prevent erosion, and preserve the integrity of your property’s landscape. If you’re experiencing water drainage issues or wish to proactively manage water runoff, consider consulting professionals to assess the suitability of a curtain drain for your specific needs.

With the installation of a curtain drain, you can enjoy a drier and more secure environment, free from the worries of water-related problems.

What Is The Difference Between A Curtain Drain And A French Drain?

Curtain drains essentially do the same thing that french drains do- get rid of the water. The main difference is that french drains deal more with groundwater while curtain drains have more to do with surface water. Curtain drains are built in a very similar way to french drains but are dug to a shallow depth.
