Trench Excavation: A shallow trench is dug in the problem area where water pools. Lining with Fabric: The trench is lined with a water-permeable landscape fabric. This fabric helps prevent soil and debris from entering the pipe. Installing the Perforated Pipe: A perforated pipe is placed at the bottom of the trench.
In most cases, we would recommend that you install a soakaway crate, in order to let the water seep away naturally into the ground.
You'd just install a surface drain on the patio area or wherever the lowest spot is. Whether you have french drains that terminate into that to gather water from the surrounding areas will depend on how it pools and drains (separate pooling areas).
However before you lay down any paving slabs, you should consider a patio drainage system. By ensuring the removal of standing water from a patio (which can happen as a result of heavy rainfall) a properly installed drainage system can help you to avoid bacteria growth and even insect infestations.
Patios must have a slight slope (1" for every 4' to 8') for proper drainage. If you don't provide enough slope, rainwater will settle into low spots, eventually softening and washing out the sand and subbase materials beneath.
ALL CHANNEL DRAIN MUST BE INSTALLED IN CONCRETE AND THE GRATE NEEDS TO BE ON THE CHANNEL BEFORE POURING. The grates can be covered with painters' tape to keep the concrete off them while the concrete is being installed to avoid staining.
If the existing concrete patio lacks a drainage system, it is a practical move to install one. In areas where the rainwater collects, cut a sloping channel. A well-cut channel directs the water away from the patio. Fill the channel with decorative stones or gravel so it meets aesthetic ideals.
Organic mulches like wood chips, bark, and straw absorb water. Inorganic mulches like rocks, gravel, pebbles, and rubber don't absorb water but may allow water to drain through the gaps between pieces.
Pea gravel is one of the best materials for landscape drainage because its small size allows for outstanding drainage. These rocks are only about ¾ inches in size. Pea gravel is available in a variety of shades, including brown, grey, blue, and red, making it a good choice for a number of different landscapes.
A concrete patio drainage channel like Slot Drain is the ideal way to protect your outdoor recreation area from the damaging effects of water. The most efficient option available, Slot Drain is a sleek, easy-to-install option that will easily handle any water runoff from your patio area.
A channel drain is a linear drainage solution designed to remove large quantities of water from a patio, or any paved, tarmac, or concrete area. It is essentially a long, narrow channel integrated into the hard landscaping covered with a removable grate, to collect and channel water away from the area.
Desired slope: To achieve the best drainage solution, you must create an incline in the yard with a slope as small as 3% or as severe as 25%. Distance from the house: The furthest area from the house or building structure should be the lowest point in the lawn to maximize water drainage away from the foundation.
Permits Needed to Install a French Drain
Generally, a small French drain on your property that doesn't change the flow of runoff entering and exiting your yard won't need a permit. Major projects that warrant your French drain to discharge into a municipal sewer or roadside ditch, however, do require one.
Dig and Line the Trench
Dig a dry well about two to four feet wide and three feet deep at the low end of the trench. Line the trench with landscape fabric and gravel. Then lay in 4-inch perforated drainpipe with the holes facing down. Continue running pipe a few inches into the dry well.
A soakaway consists of a hole dug in the ground and filled with rubble or plastic crates. It provides a solution to excess surface water by letting it slowly drain and soak into the ground instead of build up.
Trench drains may also be called channel drains and are an above-ground drainage solution. Its materials are embedded in the ground within a long, narrow trench. It has a grated covering that may look like guttering.
And, they are affordable too. In short, pvc drainage pipes are the best option for your underground drainage system.
