What you need to know about grading and drainage in residential construction.

Grading and constructing proper drainage is essential in protecting your home's foundation. Four Oaks Residential's team are highly experienced in providing proper grading and drainage solutions for residential home construction. Why is grading and drainage so important to you? Storm runoff is caused by excessive rain water and it needs somewhere to go. If there is no slope directed away from your foundation, then water can seep inside and degrade the masonry wall and mortar joints. Over extended periods of time, this causes your foundation to become weak and unstable.

What is the proper minimum slope for your home's foundation?

Typically, the minimum slope away from your home's foundation should be set to a 5% grade. This will allow for proper drainage away from your foundation and help to avoid costly foundation repairs in the future. Does your home currently have the proper slope? You can measure this yourself. All you need is two stakes, a tape measure and a string level. You can view step by step instructions in detail at Here's a link: The Spruce : Guide to Grading and Slope

Now let's talk about the different aspects of drainage.

Drainage, for construction purposes is the means of removing surplus water or liquid waste away from your home. There are three common types of drainage that are used in residential applications. They include swale drainage, french drains and dry well drainage systems.

Swale drainage is the most common, cheapest and easiest to construct. Basically, it is constructed by creating a "v" shape in the grade of the land that directs water away from your house and back into the water table.

French drains are also a very common type of drainage. A trench is cut into the ground following the path where you want your drain. Then a specific type of gravel is put down as a base to assist in drainage and to prevent erosion. Next, the perforated drain pipe (wrapped in filter fabric) is laid in place, with gravel surrounding it. Finally, covered with dirt/grass seed/sod.

Dry Well drainage systems are not as common as with the previous types mentioned. Basically, downspouts are installed around the exterior of the home and in problem areas. These downspouts drain storm runoff to an underground tank. The well will eventually disperse the runoff back into the water table, making this solution very efficient and environmentally friendly.

Swale Drainage

A swale is a carefully constructed depression on grade, that directs storm runoff away from your home's foundation. This solution reduces puddling near your home's foundation. Swales can be used in combination with french drains for maximum drainage.

French Drain

A french drain is a perforated plastic pipe that is wrapped in filter fabric. The pipe is then surrounded by gravel and buried. A french drain is a subsurface project that directs water towards a drain. This is also the most common type of drainage solution.

Dry Well Drainage

Drains or downspouts are placed to direct runoff to an underground storage well. Ultimately, the well will release the runoff back into the groundwater table. Dry wells are a very cost effective method of drainage also. Finally, they are very environmental friendly. Read more about drainage...
