Recall what a French drain is?

It is often referred to as channel drainage, weeping tiles and other terms. The name depends, for the most part, on the method and place of installation:
- Weeping tile is a drainage system along the perimeter, at the base of the building, equipped at a fairly large depth on the site.
- Backyard or garden drainage, trench drainage is often a surface-level system installed in a garden, driveway, or yard.
- Curtain drainage system – mounted at ground level or around a building to divert precipitation (rain, snow).
Why it is worthwhile to put French drainage: the main reasons
French drainage is definitely worth installing in the presence of the following problems:
- The site is always wet with soil. Suppose the yard constantly stands in puddles or appears quickly after a small rainstorm. In that case, it is worth thinking about a drainage system.
- The basement floor of the house is constantly underflooded, water periodically appears at the junctions of the wall and floor.
- Increased climate humidity. Even if the symptoms of flooding do not appear very often, if you live in an area with frequent rains, it is worth thinking about water drainage in advance.
- The retaining wall is damaged. Suppose the building is on an elevated site with a retaining wall. In that case, the water can gradually damage it, which can provoke more significant problems. If the retaining wall is damaged, it will be possible to divert water away with drainage.
At the same time, it is worth noting that the French drainage system is not the only way to combat waterlogging of the site or the house. It is best to contact professionals to advise which system is best suited to your situation.

But in some situations, the cost can go as high as $18,000. More often than not, 100 to 150 feet of the system needs to be installed for optimal drainage.

What cost items should definitely be taken into account in the project
The average cost to install a french drain depends on what building materials will be used during the implementation of the project, as well as how much the master will have to pay for the work done. This indicator is influenced by the level of complexity in the implementation of the French drainage project. Sometimes several specialists are needed to implement a project at once: not only a plumber, but also a landscape designer, a concrete worker and others. In addition, installing the system may require the purchase of sewer pipes, gravel, additional equipment and auxiliary materials.
As for the payment for the work of specialists, they take 50-200 dollars per hour. It all depends on the particular company. A large part of the budget goes to the work of specialists, and the pipes themselves will be relatively inexpensive. The average rates of plumbers are 45-200 dollars per hour. The more experienced the specialist, the more he charges. Sometimes you may need the work of a landscaper, who charges $50 to $100 an hour. If drainage needs to be arranged in the basement, it takes more time and effort. This process involves removing a layer of concrete around the perimeter of the basement for a complete drainage system. Concrete removal is calculated at a separate rate – $4.75-7.50 per linear foot (this data is relevant if the basement is a 4-inch concrete slab + the price of pouring a new concrete layer).
Materials also deserve separate attention. The installation of gutters requires the purchase of a particular pipe with perforation. Its cost is $ 0.50-3 dollars per 1 foot. In addition, you also need to buy a particular material for the cover. It will ensure the pipe is not clogged with sand and other particles.

Therefore, it is best to entrust this issue to real professionals. They will promptly, and quality install French gutters on the perimeter of the house or inside the basement. If you have no experience installing these systems, avoiding risks and contacting a professional company is better.
