Many times people use the term ” French Drain” as general name for a Drain used in or around your home. French Drains are designed to move a lot of water over a large flooded area. They are also designed to take water in on the surface of the ground or below the surface of the ground. This is very important if the water coming into the flooded area is moving through the ground or coming up from underneath. ” Sub Surface Water Movement.” The picture below is not a French Drain!
A French Drain looks like this
A French Drain can take in water in a broad area. It can move a much larger volume of water compared to a Surface Drain. Also, it can move sub surface water moving into the area where a Surface Drain won’t move any water at all.
Surface Drains are designed to move surface water only on a smaller scale in confined areas.
Each solves specific drainage problems. A Drainage System may use one or both together or even several using many types of drains.
Do you have standing water in a large area in your yard? Typically this calls for a French Drain. A French Drain is a great way to control standing water in a large grassy area. It can also protect areas from flooding to a certain degree. As long as the French Drains capacity to move water is not exceeded. If the French Drains capacity is exceeded then water will stand in the drainage area until the rain stops and the drain has time to catch up. A good way to prevent this is to install a bigger French Drain with a larger pipe. The difference between a 3 inch French Drain and a 6 inch French Drain is huge.
Another way to beef up a French Drain is to connect gutter down spouts in front of the French Drain. The water coming off the roof causes suction in the French Drain Behind it. This greatly increases the French Drains ability to move water without increasing the size of the French Drain Pipe.
French Drain Installation can be a big part of installing a Drainage System. A French Drain is not the only type of Drain that can be used. A Drainage System can utilize several types of drains including a French Drain, Surface Drain, or Channel Drain.
A French Drain is completely different from a Surface Drain. A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench. A Trench Liner is sometimes used depending on the Drainage System Design and the type of soil. The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe. This is to ensure that the Drain Pipe does not become clogged. A trench is dug that is slightly wider than the French Drain Pipe that is being used. There are several sizes of French Drain Pipe. Three Inch, Four Inch, and Six Inch are the most common sizes of French drain Pipe. The dirt that is taken out to make the trench is hauled away. It is replaced by some type of small stone or gravel depending on what is desired or available. I prefer crushed 1 inch lime stone. It is the most economical option in my area. Pea Gravel or some other type of small stone can work just as well. The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level). In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed. This helps maintain the integrity of the trench over time. It also increases the cost of the French Drain and the amount of time to install it. I install a trench liner in a French Drain about 20% of the time. Most of the time a liner in not needed.
B. Leave the French Drain as-is, but decorate it with stepping stones or landscaping rocks. Many French Drains are hidden under rock walk ways.IF YOU NEED WATER DRAINED AWAY FROM YOUR HOME OR BUSINESS CALL Us 405 203 9419
