Can you put PVC pipe under concrete?

Pack the concrete around the PVC pipe to prevent air gaps. Pack the layer directly underneath the PVC pipe; it should be packed tight to create a solid, firm foundation and to prevent cracking during temperature fluctuations. Always aim for a complete seal around the PVC pipe.

What causes PVC to crack?

Over time, PVC leeches materials known as plasticizers.

What is PVC concrete?

PVC granules reduce the thermal conductivity of the concrete but also cause mechanical strength loss. The linear decrease in the thermal conductivity of the concrete as the amount of PVC granules increases indicates that the PVC granule can be used for the production of concrete with low thermal conductivity.

What is GREY PVC pipe?
