If you install any underground plumbing pipes, in your concrete building foundation, you will need to protect them, from the concrete. You can use a variety of products and the most common of them will be a Styrofoam wrapping that can be purchased at most plumbing supply stores.
Let’s start with the waste pipes, that are made out of plastic. The concrete could actually start to put pressure on the plastic pipes as the concrete starts to expand and this pressure could actually damage your new waste pipes.
You don’t need to wrap all of the plastic waste pipes, only the parts of the waste pipes that will be exposed or in direct contact any concrete, but you do need to protect every copper water supply line that will be buried under the ground or exposed to the concrete, with a plastic sleeve. These products can be purchased again at most building supply or plumbing supply stores.
If these pipes aren’t protected properly, you could find yourself within a short time, repairing the pipes that are either inside of your concrete foundation or buried underneath your concrete foundation. Either way, this isn’t going to be a good thing.
You definitely need to wrap a plastic sleeve around the water supply pipes that are going to be buried or in direct contact with the concrete. This is a must and most building departments will require your plumbing pipes to be wrapped, before it they will sign off on your rough foundation plumbing inspection.
However, for the waste pipes, you can actually use cardboard to protect them. If you’re short on funds, why not grab some cardboard boxes, dismantle them and start using cardboard to wrap the pipes, with a little duct tape.
