If you are building foundations at an angle to the sewer pipe, you can put concrete on either side of the pipe and bridge over it.
Concrete encasement may also be required due to inadequate cover over sewer mains. Concrete encasement of a sewer main may be required for the protection of sewer pipes from additional loads imposed by structures. Concrete encasement may also be required if the minimum cover requirements cannot be met.
Yes : If the line is bedded properly and protected by enough materials to prevent crushing of the pipe below . In this case Sch# 40 PVC pipe where allowed and if in a area where frost is present the line should be insulated also . Proper pitch is needed so no water is standing in pipe in that case also .
For properly designed and installed concrete structures, there is no damage to PVC pipe from contact with concrete: no physical damage, no chemical attack, no harmful long-term effects.
You can, but it would be wise to bury the pipe in sand or pea-gravel under the slab to be poured. Not a great idea to embed the PVC pipe directly in the concrete, because of the old (and well established reliable) saw “concrete cracks”.
Things that should not be installed on top of your septic drain field include: Heavy equipment and vehicles, which can compact the soil and damage the drainfield pipes. Paving, such as asphalt or concrete, which prevents rainwater from reaching the soil in the drainfield, disrupting the natural filtration process.
A slab leak can happen anywhere a pipe runs under a concrete slab. They are more likely to occur in older homes. However, they do occur in new construction as well.
The PVC pipe will really bind to concrete. The connection is weak, though. Additionally, compared to concrete, which has an expansion coefficient of 5.5 10-6 in/in oF, PVC has a significantly higher expansion coefficient of 28 10-6 in/in oF. It enables the concrete's bond with the PVC pipe to be broken by contraction.
The hardness of concrete can protect PVC pipes from damage. 2. Saving Space: Embedding pipes in concrete can save the use space of buildings and make the architectural design more concise and beautiful.
Never build over drainfields
The soil beneath the drainfield needs oxygen so that the microbes in the soil can treat the effluent from the drainfield. However, if a permanent structure is built over a drainfield, it can restrict the oxygen flow into the soil and restrict the evapotranspiration process.
Not only can the weight from the vehicle put stress on the tank and cause damage, it can also disrupt surrounding infrastructure, including pipes, leading to leaks and, in the worst-case scenario, major property damage. How much weight can you put on a septic tank?
Note: Council require a minimum clearance of 1.0 metre between proposed structures and vacuum / low pressure sewer lines, but will allow limited development over or near valve pits.
It is possible to build over a public sewer but you will require express permission from the owner of the sewer, not the land owner. In most cases the sewer owner will ask you to divert the sewer around any proposed development though open land so they can have full acces to dig up the pipe if anything goes wrong.
No, its 100% not okay. It WILL fail. If you've ever claimed up that mess, you know darn well you do not want to bury this problem under concrete .
Yes, your main water line can definitely (and usually does) run underneath the footing. Your sewer line also usually needs to run under the footings to allow for downward slope from any plumbing drains in the basement to the sewer main.
If you are building foundations at an angle to the sewer pipe, you can put concrete on either side of the pipe and bridge over it.
To protect pipes that go through surfaces prone to corrosion, such as concrete or metal, pipe wrap tapes are highly recommended. These tapes act as a barrier, preventing contact between the pipe and the corrosive material.
Dig-up test results in the U.S. and around the world indicate that PVC pipe can be expected to provide reliable service in excess of 100 years.
QUIKRETE® Polyurethane Construction Adhesive (No. 990212 & 990213) is a high-performance, construction grade adhesive designed for permanently bonding concrete, brick, marble, stone, wood, glass, aluminum, steel, PVC and tile.
The preferred method is to inject the gap around the pipe with high-viscosity polyurethane.
A piping passing through concrete walls, floor, slabs, and masonry walls shall be provided with sleeves for protection.
When a water pipe leaks or bursts under the concrete foundation, this is a slab leak. Often, a homeowner does not even realize water is leaking under and around the slab.
A slab leak is a type of water leak that occurs beneath the concrete foundation (or slab) of a home when a water pipe breaks or leaks. These leaks are often caused by soil shifts, pipe corrosion, or poor installation and can lead to severe damage, including foundation cracks, water damage, and mold growth.
Sealing around cracks with epoxies or pull-through liners can provide a trenchless solution for minor leaks. Deeper splits may require spot excavation to access and replace damaged pipe sections. In some cases, if the full line shows signs of deterioration, complete replacement above or below ground may be best.
