Gravity Fed Drainage Solution: French Drain with Dry Well

When a French drain and dry well are combined, you get a highly effective drainage system that operates with the help of gravity, and even though French drains and dry wells are ancient systems, they are still quite effective for drainage purposes. Essentially, a dry well is a pit dug away from your home that collects excess water from your home and slowly percolates the water into the ground.

A French drain is a drainage system that drains water collected from your house safely away from your foundation walls. French drain installation with a dry well involves a systematic process to effectively manage water drainage. Trenches are dug around your property, and weeping tiles are laid on these trenches. These French drains carry water to the dry wells and collect the water in those wells. The dry well then does its job. The process is straightforward, effective, and a popular above-grade draining technique, and installing French drain with a dry well is a very economical drainage approach.

What are the different types of French drains?

French drains are a go-to solution for redirecting water away from vulnerable areas. They play a crucial role in managing surface and groundwater. They safeguard properties from water damage and prevent erosion. Let’s get into the various types of French drains:

It is designed to collect surface water. This drain consists of a shallow trench lined with gravel and a perforated pipe. It effectively directs water away from the surface.
This drain is used for subsurface water issues. Getting this drain involves digging deeper trenches to capture water below ground level. It prevents saturation and potential structural damage.

The Interior French Drain is installed within basements or crawl spaces. This drain intercepts water before it infiltrates the interior and directs it to a sump pump for removal. It safeguards the building’s foundation.

Exterior french drain installation is done outside the building’s foundations. This drain prevents water from seeping into basement walls by intercepting it before it reaches the foundation. It effectively protects the structure from moisture-related issues.

How Does A French Drain Work?

A French drain is a type of drainage system designed to redirect water away from an unwanted area. It prevents from damage to the building’s foundation or a low-lying yard area. Here’s how it typically works:

First, a trench is dug into the ground. The size and depth of the trench will depend on the specific needs of the drainage project.

A layer of gravel is then placed at the bottom of the trench. This gravel bed serves multiple purposes: it provides a stable base for the drain, helps to filter out debris, and promotes water infiltration.

A perforated pipe made of PVC, is placed on top of the gravel bed. This pipe helps in collecting and transporting water away from the area. The perforations allow water to enter the pipe from all sides.

 Once the pipe is in place, more gravel is added to the trench, covering the pipe completely. This additional gravel provides further filtration and support for the system.

In some cases, a fabric lining is placed over the gravel before backfilling the trench with soil. This fabric helps to prevent soil and debris from clogging the gravel and pipe over time.

Finally, the trench is backfilled with soil and cover the gravel and pipe completely. The soil should be graded away from the area being drained to ensure proper water flow.

Dry Well and French Drain Installation Process

01

The first step in French drain installation is to determine a location to install the dry well. We make sure that the dry well is far away from your house. We dig a hole around 4 feet deep and perform a percolation test. If the pit fills with groundwater, the location is unfit for installing a dry well, as the water will not drain. But if groundwater does not serve the hole, we pour around 5 gallons of water into the hole and check the drainage speed. If all calculations are correct, we choose that spot for dry well installation.

02

We then install a dry well with a suitable capacity. The dry well capacity is selected based on the amount of water to be drained. A high-capacity dry well is installed if the area receives high rainfall or the house generates more excess water. Otherwise, a medium-capacity dry well works just fine.

03

Then, we dig trenches to install French drains. We dig around 3-foot-deep and 12” inch-wide trenches. We give about 1-inch slop for every 8-10 feet of trench. Doing this can help water flow away from your property.

04

We then lay a filter fabric to prevent dirt and debris from clogging the drain pipes. We install perforated pipe in the trenches. We pour gravel all around the weeping pipes. The downspout extension and the sump pump outlet are connected to one end of the weeping tiles. The other end of the weeping tile is connected to the dry well. All excess water from the downspout, sump pump outlet, or from the soil is carried through the installed French drain into the dry wells.

05

Another layer of gravel is poured over the French drain, and the backfilling is done to restore the original grading. We then clean the area, and the process of French drain installation is complete. There you go, a perfect drainage system that operates with the help of gravity.

What Is The Cost Of French Drain Installation In Toronto?

The cost of French drain installations in Toronto varies due to various factors. The major factors are the size of the area needing drainage, the depth of the drain required, the materials used, and labour costs. Generally, you can expect to pay anywhere from $20 to $60 per linear foot for basic French drain installation. However, this cost can increase with additional complexities. It’s best to get quotes from French drain installation contractors in Toronto and get a more accurate estimate for your specific project.

Essential Tips For French Drain Installation

An efficient French drain system greatly enhances the drainage around your property. Whether you’re a seasoned DIY enthusiast or a homeowner, mastering the essentials of French drain installation is key to success. Check out these tips:
01
Identify the area where water tends to accumulate or where drainage is needed. Ideally, this should be in a slightly sloped area away from structures.
02
Determine the best path for the French drain. Consider the natural flow of water and any obstacles in the landscape before French drain installation.
03
Dig a trench approximately 12 inches wide and 18 to 24 inches deep. Also, ensure slopes downward at a rate of 1 inch for every 8 feet towards the desired outlet point.
04
Use high-quality perforated pipe and landscape fabric. This ensures optimal drainage and prevents clogging from soil and debris.
05
Place the perforated pipe at the bottom of the trench with the perforations facing downwards. Connect multiple sections with connectors, if necessary.
06

Fill the trench with coarse gravel or aggregate, covering the pipe completely. This promotes water filtration and prevents soil from clogging the pipe.

07

Cover with landscape fabric over the gravel to prevent soil from seeping into the drainage system. It allows water to flow freely.

08
Carefully backfill the trench with soil. Also, ensure it is firmly packed to prevent settling.
09
Direct the end of the drain pipe towards a suitable outlet. It can be at a storm drain, dry well, or low-lying area where water can safely disperse.
10
After installation, test the French drain by pouring water into the trench. Observe how quickly it drains away. Make any necessary adjustments if needed for optimal performance.
11
Inspect the French drain periodically. Also, make sure it remains free of debris and functions properly. Moreover, remove any accumulated debris and inspect for signs of damage or clogging.
12
If you’re unsure about any aspect of French drain installation or if the area is complex, hire a professional french drain installer for assistance.

We had a leak from two sources in our furnace room, that occurred after a moderate to heavy rainfall. We hired GJ Macrae to excavate by the outside wall, repair the cracks and protect the wall with a membrane and mesh. Part of the trench had to be dug by hand, due to a gas line, and part could be done by machine. The GJ Macrae team were all very skilled and professional, and completed the job in three days. Now the trench has been refilled with the earth and gravel and it will take some time for the ground to settle. We have had a few heavy rains since the job was completed, and our basement is now completely dry! We highly recommend GJ Macrae!

Job was done in 2 days which I was amazed it could be done that quickly! That’s a lot of pails of concrete and rock that had to be shuttled in and out of the house! The guys were all very friendly and let me know everything that was being done and answered all my questions! The bowed wall looks solidly supported now with carbon fibre strapping and the water found beneath the floor is now being safely routed through newly installed Plastic Weeper to our sump. We now have peace of mind that we can finish the basement with no leaks or crumbling walls! Thankyou Gavin, Maggi, Ricardo and Jay!

We would like to express our gratitude to G.J. McRae for the exceptional job they did in restoring our peace of mind. Every time it rained or snowed, our basement would leak, causing us great distress. However, the crew from G.J. McRae arrived promptly, worked diligently, and efficiently resolved the issue. They even left our backyard in excellent condition, cleaning up after themselves. We cannot thank you enough for the outstanding service and for making us feel confident that the problem is now completely resolved. We are so happy to be able to not worry about this any longer.

Frequently Asked Questions

A French drain does not necessarily need a dry well. However, incorporating one can enhance the drainage system’s effectiveness, especially in areas with poor soil drainage. A dry well collects and disperses excess water from the French drain. This prevents water from accumulating and ensuring better water management.
Yes, a French drain typically needs a membrane or landscape fabric. The membrane helps to prevent soil and debris from clogging the gravel and pipe within the drain. This ensures that the drainage system remains effective over time. This also allows water to flow freely into the pipe and away from the area.
The best pipe for a French drain is usually a perforated PVC or corrugated plastic pipe. Perforated pipes allow water to enter through small holes along the length of the pipe, facilitating efficient drainage. PVC pipes are durable and smooth. This also reduces the risk of clogging, while corrugated plastic pipes are flexible and easier to install in various terrains.
The amount of water a French drain can handle depends on its design, including the length, depth, diameter of the pipe, and the soil type. Generally, a properly installed French drain with a standard 4-inch diameter pipe can handle moderate to heavy rainfall. However, for precise capacity, it’s essential to calculate based on the specific drainage needs and conditions of the site.

There are several places where a French drain should not be installed:

  • Near foundations: Installing too close to a building foundation can undermine the structure.
  • Under driveways or heavy load areas: These areas can compact the drain and reduce its effectiveness.
  • In poorly draining soil without proper outflow: If the soil doesn’t drain well and there’s no proper outflow, the French drain won’t function effectively.
  • Near septic systems: Avoid placing French drains near septic systems to prevent contamination and system interference.
  • In areas with high water tables: In these locations, the drain might remain saturated and ineffective.
