NO. you should never pour concrete on any pvc conduit or water pipes unless you wrap the pipes with a form wrap to allow expansion and contraction and any penetration thru the concrete or install a 4in or 6in sleeve under the slab to pass the pipes though.
Can PVC be encased in concrete?
PVC pipe embedded in concrete should be fine under most codes I’ve seen. You’d need to sleeve something like black, galvanized, or no-hub iron pipe, but PVC and ABS are impervious on any reasonable timeline (~hundreds of years.)
How do you support horizontal PVC pipe?

Can CPVC be encased in concrete?
CPVC can be installed under slab, underground or encased in concrete.
Can you bury PVC conduit in concrete?
PVC conduit is used in and under concrete slabs. Installing conduit under or in concrete slabs protects the wires from the weight and corrosion of the cement. It also allows future expansion of the electrical system by pulling additional wires through the conduit.
Do I need to sleeve PVC through concrete?
Quote from the video:
Quote from Youtube video: Again there needs to be some type of a separation I recommend something at least a half inch thick. Like I said cardboard.
How much weight can PVC pipe hold horizontally?
How to use our Load Deflection Chart:
| Horizontal Span Length (ft.) | 1/2 in. Size | 2″ Size |
|---|---|---|
| 1′ | 18 lb. | 70 lb. |
| 2′ | 5 lb. | 55 lb. |
| 3′ | 3 lb. | 35 lb. |
| 4′ | 2 lb. | 28 lb. |
How often does PVC need to be supported?
every 3 ft.
PVC must be supported every 3 ft. for trade sizes ½ inch through 1 inch. The support distance increases as the conduit size gets larger. For example, 2 inch PVC conduit can be supported every 5 ft; 6 inch PVC conduit can be supported every 8 ft.
Is concrete corrosive to PVC?
A. According to Bernard Erlin, the principal chemicals in concrete that could conceivably attack plastics are calcium hydroxide, sodium hydroxide and potassium hydroxide. Erlin cites a table from Handbook of Chemistry and Physics stating that rigid PVC has excellent resistance to strong alkalies.
How deep should PVC conduit be under concrete?
What is the minimum depth for placing Schedule 40 PVC conduit below a concrete slab? A. If it’s under a building, there is no depth requirement. If it’s placed outside under a concrete slab, then the minimum cover is 4 inches [Table 300.5].
Can you pour concrete over conduit?
The best time to run conduit is before your pour the concrete slab. This allows you to install the conduit under the slab in a location where it is well protected. PVC conduit is typically used for these applications because it is weather-tight and doesn’t corrode due to exposure to the acidic concrete.

Quote from the video:
Quote from Youtube video: Cover around the pipe. Then i went around it with hot glue to seal it around the outside diameter and the inside diameter. Remember that this is intended to be a cheap easy temporary.
How do you seal a pipe through foundation?
Polyurethane Seals for Foundation Pipe Penetrations
The preferred method is to inject the gap around the pipe with high-viscosity polyurethane. This polymer can be used on both wet and dry materials, and it can work its way into small hairline cracks to make a more powerful bond.
Does concrete stick to plastic?
Concrete also sticks very well to plastic. Treating plastic with a release agent prior to coming in contact with concrete is the best way to ensure your plastic buckets and tools remain free of dry concrete.
