The way to Lay a Pebble Drain in a Backyard
Inadequate drainage in your yard often causes severe erosion and rendering it hard to establish a healthy lawn. Drainage problems are often caused when building work disrupts the natural drainage pattern and may flood an entire yard every time it rains. A very simple pebble drain, called a French drain, collects storm water and diverts it into a low point in your yard, public storm water drain or a small retention pond. French drains may be set up without drainage pipe, but perforated pipe would be the ideal choice when you need to station huge amounts of water immediately away from the yard.
Dig a ditch for the pebble drain that’s 6 inches wide by 6 inches deep if you’ve got a little drainage issue, or make the dump 12 by 12 inches when you’ve got severe drainage problems so there is a greater surface area to collect the water. Sandy soil tends to drain rapidly, therefore a 6-inch drain is acceptable, but slow-draining clay soil requires a broader dump. Lay out the dump design with garden hoses, mark the ground using landscaping spray paint, then dig the dump with hand digging tools or heavy equipment. Ensure that the dump has at least a 1 percent grade.
Lay permeable landscaping material in the bottom of the dump and extending up the sides to prevent soil from mixing with the gravel.
Insert 1 to 4 inches of 3/4-minus gravel into the bottom of the dump and then spread it out evenly. A 12-inch-deep dump may adapt 4 inches of gravel, but a 6-inch deep dump can only accommodate 1 inch of gravel.
Connect pieces of 4-inch-diameter drainage tile, also called perforated pipe, and put it on top of the gravel in the dump. Perforated pipe connects with couplings, or the ends have triumphed which you may just push together. Attach a piece of wire mesh screen to the end of the pipe which deposits the water; wrap the screen around the pipe and fasten it using a bit of wire. You may omit the drainage tile if you just have mild drainage problems.
Lay permeable landscaping material above the pipe to stop soil and gravel dust from clogging the perforations. You can either lay the cloth to finish the cover dump or wrap the pipe in the cloth to block out debris.
Cover the pipe along with landscaping material with little seams, either filling the dump to grade using seams or leaving a few inches to the top so that you may add cover the top with smooth, decorative cobblestones.
