Gravel trenches can be adapted to suit various drainage needs, from small garden beds to larger yard areas. They are less expensive to install than traditional French drains, and you can DIY a gravel trench with some essential tools and materials.
A swale is best for managing surface water over large, open areas, and is ideal for settings where a natural look is preferred. A French drain is going to be better for subsurface water issues, particularly where groundwater is a problem or you need to protect foundations from water damage.
Yes, using gravel around your house can help improve drainage. Here are some reasons why: Water Permeability: Gravel is permeable, allowing water to flow through it rather than pooling. This can help direct water away from the foundation of your home.
Interior French drains are meant for waterproofing the basement or draining your crawl space. They cost more because contractors must tear out the basement floor (most often made of concrete), install the drain, and then repair it.

Installing a French drain costs $500 to $18,000, with a national average of $9,250. On average, you can expect to pay $10 to $100 per linear foot, or between $500 and $5,000 to have a 50-foot French drain installed.
Aside from what we've listed here, the difference between a French drain and a trench drain is that a French drain is used for water that is underground while a trench drain diverts excess water from a surface.
Compared to sand, gravel allows excess water to drain much more quickly. It is less likely than sand to retain water in areas where it is unwanted. Gravel is also more likely to keep up with the shifting soils in your yard.
Drainage swales are shallow ditches that blend in with surrounding landscape design, facilitate water management, and encourage natural irrigation. Swales take advantage of natural slopes in the land to direct water downward into all the soil as opposed to letting it pool above ground or waterlog a specific region.
Clay soil has poor permeability, meaning it doesn't allow water to pass through easily. In such cases, the effectiveness of a French drain may be limited as the water may struggle to drain away from the area efficiently. French drains may not be suitable for areas with high water tables.
The primary function is to convey stormwater runoff and there is minimal water quality benefit; however, rock lined and vegetated swales may decrease the velocity of water and facilitate some infiltration. Vegetated swales may have the added benefit of filtering stormwater as it flows through the swale.
A spoon drain is a concrete drain formed in line with the ground surface and its purpose is to collect stormwater before it can soak into the ground. Stormwater falling on the ground is directed towards the drain and the bottom of the concrete drain is sloping. It takes water away before it can soak into the ground.
This simple system uses natural landscaping to prevent flooding rather than industrial materials. Affordable: The average cost to build a swale drainage ranges from $0.50 to $1 per square foot or $5 to $15 per linear square foot, making this drain type one of the most affordable to install.
It is not absolutely necessary to use perforated pipe to create a French Drain. However keep in mind if you remove the Perforated Pipe the water flow will be slower through the French Drain. If you do not use a Perforated Pipe consider increasing the size of the stone to 1 1/2”.
Pea gravel is one of the best materials for landscape drainage because its small size allows for outstanding drainage. These rocks are only about ¾ inches in size. Pea gravel is available in a variety of shades, including brown, grey, blue, and red, making it a good choice for a number of different landscapes.
Erosion prevention: If you're concerned about erosion, river rock is a great choice, as it prevents soil from moving. In fact, it can stay in place on even steep slopes and hills with no problem. Cost-effective: Because of its longevity, there's no upkeep, which means rocks are more cost-effective than mulch.
If you have a problem area where water tends to pool, a trench drain may be the best option. If you want a drainage system that is less visible or installed around the perimeter of yo French drains are long-buried trenches containing a perforated pipe enclosed by gravel.
French drain depth: About 8 inches to 2 feet deep should be sufficient for many water-diverting projects, though related systems, such as those built around foundations and sub-ground living spaces, as well as the bases of retaining walls, may be deeper.
TRENCH DRAIN CONS:
Heavy forklifts and other equipment can damage the grates. High flow rates into the drain can result in splashing, causing contamination. The wider opening, though covered by a grate, can create a tripping hazard.
If installing the drain involves diverting a stream or affecting a wetland, you likely need a permit to move forward. Generally, a small French drain on your property that doesn't change the flow of runoff entering and exiting your yard won't need a permit.
Labor costs: French drain installation is labor intensive, so the local cost of labor has a huge impact on pricing.
