Plumbing Under Concrete Basement Floor

At this point you will no longer see the horizontal drainpipes and the main sewer line but you will see the stubs that extend vertically out of the sand.

Plumbing under concrete basement floor.

From there the pipe runs under the floor and out to the city sewage system under the street. So before you can do any real planning you have to find that line. There is no crawlspace or basement beneath which means the plumbing is under the slab foundation. Homes with this a concrete slab foundation rest atop this rock solid block.

Houses built on a slab lack crawlspaces and there is no space under the floor. Diameter vertical pipe that runs into the basement floor. Plumbing design installation for homes with basements. For the purpose of clarity let us take the three types of houses discussed in this book the house with basement the house without basement and the house with a poured concrete slab floor and show how the plumbing installation should be done for each one.

How to run plumbing under concrete. Rising groundwater causes hydrostatic pressure and that causes soil to push on your basement walls and floor. It can also run under. Considerations cutting through a concrete floor should be a last resort.

A concrete slab foundation is constructed by pouring concrete a mixture of gravel or broken stone sand cement and water within a mold to cure. If your basement is in the way and there are structural deficiencies or cracks in the concrete then your basement becomes the path of least resistance and the groundwater goes there. The concrete slab is often placed on a layer of sand for drainage or to act as a cushion. But it may run at an angle rather than straight out to the street.

Before the concrete trucks come the contractor fills in the area over the network of plumbing pipes and drain lines with compacted sand.
