Yes, PEX can be buried in concrete. It is a common misconception that PEX cannot be buried in concrete because it is not rigid like metal piping. PEX is a flexible piping material that is made from cross-linked polyethylene.
It is incredibly versatile and can be used for a variety of applications, including buried in concrete.
If you’re wondering whether you can bury PEX piping in concrete, the answer is yes! PEX can withstand the weight of concrete without being damaged, so it’s a great option for running piping underground. Just be sure to use the proper fittings and installation methods to ensure a watertight seal.
How to Protect PEX Underground
How long does PEX last in concrete?
If you’re wondering how long PEX pipe will last in your concrete slab, the answer is quite a long time! PEX is a very durable and flexible material, so it can withstand a fair amount of wear and tear. Plus, it is resistant to many common chemicals that can cause other types of pipe to degrade.
So, you can expect your PEX pipe to last for many years, even decades, without any problems.
Do you have to sleeve PEX through concrete?
If you’re running PEX pipe through concrete, you don’t necessarily have to sleeve it, but doing so can provide extra protection for the pipe. Sleeving PEX pipe through concrete can help to prevent the pipe from being damaged by the concrete, as well as provide additional support for the pipe. There are a few different ways that you can sleeve PEX pipe through concrete, so be sure to consult with a professional before beginning your project.
Can PEX tubing be buried underground?
Yes, PEX tubing can be buried underground. However, there are a few things to keep in mind. First, PEX tubing must be buried in a conduit.
Second, the burial depth must be at least 18 inches. And third, the burial depth must be marked on the tubing so that it can be found if necessary.
What type of PEX can be buried?
There are three types of PEX that can be buried: PEX-A, PEX-B, and PEX-C. PEX-A is the most flexible type of PEX and is therefore the easiest to work with when buried. PEX-B is less flexible than PEX-A but is still flexible enough to be buried.
PEX-C is the least flexible type of PEX and is not recommended for burial.

What kind of pex to use in concrete
If you’re looking to use PEX in concrete, there are a few things you need to know. First, there are three different types of PEX – A, B, and C – and each has its own benefits and drawbacks. Second, you need to make sure that the PEX you’re using is compatible with the concrete mix you’re using.
Third, you need to be aware of the expansion and contraction of PEX in concrete, which can cause problems if not properly taken into account.
Type A PEX is the most commonly used type of PEX for concrete applications. It’s strong and durable, and able to withstand high temperatures.
However, it’s also the most expensive type of PEX.
Type B PEX is less expensive than Type A, but it’s not as strong or durable. It’s still able to withstand high temperatures, however, so it’s a good choice for concrete applications that don’t require the same level of strength and durability as Type A.
Type C PEX is the least expensive type of PEX, but it has the lowest temperature rating of the three types. It’s still able to be used in concrete, but it may not be able to withstand the high temperatures that are necessary for some applications.
When choosing a PEX for use in concrete, it’s important to make sure that it’s compatible with the concrete mix you’re using.
Pex fittings in concrete
If you are looking to add pex fittings to your concrete project, there are a few things you need to know. Pex fittings are a great way to add flexibility and durability to your project, but they can be a bit tricky to install. Here are a few tips to help you get the job done right.
1. Pex fittings need to be installed before the concrete is poured. This means that you will need to create a hole in the concrete pour for the fitting. The best way to do this is to use a hammer drill and a concrete drill bit.
Drill a hole that is slightly larger than the fitting you are using.
2. Next, clean out the hole you just drilled. This will help ensure that the fitting will have a good grip on the concrete.
3. Now it is time to install the fitting. First, apply a generous amount of plumber’s putty to the threads of the fitting. This will help create a seal.
Next, insert the fitting into the hole you drilled.
4. Use a wrench to tighten the fitting. Make sure that the fitting is tight enough so that it does not leak, but not so tight that it is difficult to remove.
5. Once the fitting is tight, apply a layer of caulk around the edge of the fitting. This will help create an even stronger seal.
1/2 or 3/4 pex for radiant heat
If you’re considering using PEX tubing for a radiant heat installation, you may be wondering whether to use 1/2″ or 3/4″ tubing. Here’s a brief overview of the differences between the two types of tubing to help you make the best decision for your project.
1/2″ PEX tubing is the most commonly used size for radiant heat installations. It’s less expensive than 3/4″ tubing and is less likely to kink, making it easier to work with.
However, it has a lower heat capacity than 3/4″ tubing, so it may not be the best choice for larger installations or for installations in very cold climates.
3/4″ PEX tubing is more expensive than 1/2″ tubing, but it has a higher heat capacity and is less likely to kink. It’s a good choice for larger installations or for installations in very cold climates.
ultimately, the best choice of tubing size for your radiant heat installation depends on a number of factors, including the size of the installation, the climate, and your budget. Talk to a radiant heat expert to get more specific advice for your project.
Conclusion
Yes, PEX can be buried in concrete. There are a few things to keep in mind, though. First, make sure the PEX is properly rated for burial.
Second, make sure the concrete is properly cured before burying the PEX. Third, make sure the PEX is properly protected from any sharp objects that might puncture it.
