Poor drainage in yards and basements can cause all sorts of problems, from staining and mess to an increased risk of rot and corrosion. Whatever the cause, excess water needs to be removed as quickly and efficiently as possible.
One of the most effective and economical ways of dealing with the problem is a French drain, or a system of perforated pipes laid under the surface of the ground to guide water safely away from your property.
There are two main types of perforated pipe you can use for this drainage system: corrugated and rigid plastic.
Corrugated Drain Pipes
Corrugated perforated pipes are inexpensive and easy to install and offer many other benefits.
- They're light and easy to handle when fitting.
- Corrugated plastic pipes are flexible. They don't need to be laid in a perfectly straight line and can even turn around corners.
- The low cost of corrugated drainage tubing means it's ideal for draining larger areas.
- Their flexibility means they can cope with natural settling of the soil without cracking.
- They can withstand a large temperature range without splitting or cracking and can even be laid above ground if necessary.
In some situations, a heavier-duty solution can be a better choice.
Plastic Culvert and Drainage Pipes
Plastic culvert pipes are made from rigid PVC, which gives them several additional advantages. Because they're rigid, they can be cleaned out more easily using power tools if they become clogged. However, they can still be laid around corners using flexible connectors.
They're easier to lay at the correct angle for gravity-assisted drainage, and can drain effectively when laid at shallow angles, thanks to their smooth sides.
Although rigid and strong, they're much lighter and easier to handle than traditional drain pipes made from metal or clay and are also less prone to cracking under pressure or impact.
They can handle greater volumes of water than corrugated pipes, and can be used for sewer piping as well as drainage. Plastic culvert pipes are highly resistant to corrosion from acids and salts compared to metal tubing.
While rigid plastic pipes cost a little more, once installed they'll last for years even under heavy water flow working conditions.
What to Look For
Whichever type of pipe
you choose, there are a couple of things to look out for:
First, check that the pipe bore (the inner diameter of the pipe) is wide enough for your needs. For example, a 4" pipe bore can drain approximately 25 gallons per minute when laid at a standard 0.5% slope.
Also, check the temperature ratings for the pipe you're considering. Pay specific attention to check that it's certified for sub-zero operation, if you experience such temperatures where you are installing the pipe. Also check the certified max temperature if it will be laid in shallow ground in hotter areas.
Drainage Pipe Accessories
We also stock drain pipe accessories to make installation and operation more effective, including:
- Pipe Socks: Available separately or already fitted to the pipes, pipe socks help to prevent clogging and keep the pipe's contents flowing smoothly.
- Flexible Couplings: Rigid pipes can be installed around turns using flexible couplings and connecting adapters.
