Line the Trench with Filter Fabric To keep the
RPE (Reinforced Polyethylene)
RPE liners are considered one of the best options for drainage ditches due to their combination of strength, flexibility, and ease of installation.
Add a layer of sand or small rocks (optional): If you want an even base for your drainage rock, you can add a layer of sand or small rocks before adding the larger river rock. This not only helps with drainage but also prevents the larger rocks from sinking into the soil over time.
Non-Woven Drainage Fabric
On the other hand, non-woven fabrics are made using the same polypropylene materials, but with needle-like punctures that allow maximum water drainage. That's why non-woven fabrics are the top choice for creating a landscape drainage system.
Fill with macadam 11/16 about 30 cm from the crown of the pipe. The backfill must cover the whole width of the pipe trench. Fold the geotextile fabric and place this overlapped approximately 40 cm. Now fill using the masses that were previously excavated.
Compacted soil: Compacted soil backfill comprises job site materials that are packed into the trench. Compacted stone: This option entails compacted granular backfill, which is best suited for areas that require paving.
Pack down your ditch as much as possible then line it with gravel or rock to keep it stable. From there you'll want to line the ditch with reinforced heavyweight ditch liners. This will reinforce the walls and floor so that water doesn't erode the soil around your ditch.
Pea Gravel: Small, smooth, and round, pea gravel is both aesthetically pleasing and effective in allowing water to pass through quickly. River Rock: Larger and more decorative, river rock can be the best choice for a significant drainage project. It offers a balance between functionality and landscape aesthetics.
Landscape Fabric vs Drainage Fabric. Landscape fabric / drainage cloth is used in landscaping for water to pass through. Drain Field fabric is used in septic drain fields as a filter. They both act as a barrier, are from the same class of synthetic textiles and are similar in their construction.
The best moisture-wicking fabrics include polyester and merino wool, both of which are often used in sports and outdoor pursuits, when staying dry is important. How does moisture wicking fabric work? Sweat is made from 99% water. Moisture wicking fabrics do not absorb water.
River rock tops the list of the best rocks for installing in French drains. Natural round rocks are ideal because their size and shape allows the water to drain more effectively. It's vital to use washed rock because it has been cleaned of debris and particles, which will help prevent clogging the drainage system.
Both crushed stone and gravel serve as excellent drainage materials. Gravel is often used in French drains, septic drainage fields, and other drainage applications, while crushed stone is used in similar applications where a firmer base is needed.
Ideally a series of check dams should be installed along the length of the ditch. At minimum, a check dam at the downstream end of the ditch will prevent sediment from leaving the ditch.
In general, you want to aim for ½ inch to 1-inch gravel for drainage. Areas that will see especially heavy flow may need larger gravel. Or, projects without drainage pipes may also need larger gravel. For example, a French drain without perforated pipe needs 1 ½ inch gravel.
It involves inserting a flexible liner made of polyester or fibreglass into the existing drain pipe and curing the liner in place using heat, steam, or ultraviolet light.
The best type of fabric for a drainage project such as a drain field or french drain is non-woven geotextile landscape fabric.
Woven landscaping fabric's tiny holes allow both water and nutrients to seep via to the earth, while still averting weeds from growing up toward the sun.
If you are considering installing an underground drain we recommend using noncorrugated PVC for your pipe. The smooth inner surface prevents buildup in the ribs.
Dig the trench
Use a shovel or a hoe to dig out an area large enough to accommodate an average-sized drain pipe. We recommend digging it about one foot wide and 18 inches deep. The wider the trench, the easier it is to collect water and the lower the chance of clogging.
A rock drainage ditch refers to when one uses rocks in a drainage ditch to assist with the water flow, to prevent erosion alongside roads and driveways, and to help prevent erosion on lots with steep slopes.
Line the ditch on all sides with landscape fabric to prevent soil erosion. Place a layer of gravel at the bottom of the ditch. A perforated plastic pipe is laid on top of the gravel and surrounded by gravel on the sides and top.
