The benefits of using a plastic soakaway boxes instead of rubble
This entry was posted on November 14, 2017.
Excess water build-up through gutters, driveways or a French drain can cause problems for your home if it is left to filter through to communal piping. Too much water can cause them to flood and burst, leading to a lot of timely repair work. It could also lead to your property becoming waterlogged and compromised over time. Building your own personal soakaway is a great way of unloading the burden from the drains, and getting rid of the water naturally.
Why use a plastic soakaway instead of rubble
Traditionally, the method of building a soakaway includes piling rubble into the hole and around the drainage pipe. Though this is an acceptable solution, there are a few benefits to using soakaway crates or boxes instead. First off, they require much less manual work, as the crates are fairly light and easy to transport. They come flat-packed and you simply clip them together to fit the required size. As opposed to this, rubble requires a lot of lifting, and you may need a van or flatbed truck to help you transport it.
This process can mean that it is much cheaper to purchase plastic crates as it takes away the need for you to hire a specialist vehicle, or to pay a company to deliver the rubble to you. Finally, using plastic soakaways can cut down on the amount of time you need to spend building the soakaway, Once the hole is dug and the piping laid, adding the plastic soakaway and covering it over can be an incredibly fast process.
How to fit your plastic soakaway
Whenever you are building a soakaway, there are a few important principles that you need to follow:
1. Always ensure the drainage pit is at least five metres away from any buildings.
2. Before adding the plastic soakaway, ensure that the hole still lies above the water table. If you notice that the hole starts flooding on its own, this means it’s below the water table and any water transferred there will have nowhere to drain to.
3. Make sure that the pipe which feeds the hold has a drop of 100mm for every 4m of pipe.
4. The pipe needs to be at least 75mm in diameter, though 100mm is more advisable.
5. Wherever possible, ensure the pipe is straight rather than having any bends, this reduces the risk of blockage.
6. Check with the local authorities before you start any building work, as you need to ensure you meet Local Building Regulation.
7. The drainage pit itself needs to be 1mx1mx1m below the point where the drain enters.
Fitting your plastic soakaway
Once you’ve got your pit dug and the drainage laid, it’s time to fit the plastic soakaway. First off, make sure you purchase the correct soakaway. Typically speaking, green ones are designed for use in non-traffic areas, whereas blue and black ones are used for traffic areas, such as below your driveway. They are designed to bear the load of a much greater weight above.
Before you fit the soakaway, you will need to line the inside of the hole with a tough and porous membrane like geotextile fabric. This membrane protects the inside of the crate from getting clogged with dirt and soil - instead, only water can filter through. Now it’s time to fit the soakaway, and you can knock away a small circular hole on one side, which you then fit the drainage pipe into. Finally, make sure that the whole crate, as well as the point where the pipe enters the crate, is entirely wrapped in the membrane.
