Jul 13, 2014 Our house was built in 1972, brick veneer on a concrete slab in Canberra, ACT, Australia (brief hot summers and, by North American standards, brief mild winters). All water services, hot and cold, pass through insulated 1/2" copper tubing (yes, we have gone metric here but these were laid before metrication was completed) in the slab.
Jun 07, 2017 Here at Nu Flow, we have the pipe repair technology to repair your copper pipes without destroying your concrete or masonry. This is because we use epoxy coatings and pipe liners to seal and restore your copper pipes in concrete slab. For potable water pipes, we generally use epoxy coatings. This is a thick, viscous liquid that is blown through ...
The copper tube must be completely embedded in the concrete and adequate provision for thermal expansion should be provided where the tube enters/exits the concrete. It is also acceptable to run a copper water tube through a concrete floor or wall, provided that allowance is made for the lateral thermal expansion and movement of the tube and ...
Sep 01, 1998 Erlin also says that very small amounts of ammonia and possibly nitrates can cause stress corrosion cracking of copper pipes embedded in concrete.

Sep 03, 2019 Heating system pipes can be installed just as you like but then there is good practice. If pipes are burried in concrete then allowance needs to be made for expamsion. Corrosion usually needs water present as well. If this is above ground floor then there is little risk but if its ground floor then the risk is much higher as some dampness is ...
Dec 11, 2004 I have a copper line coming through my slab for water service. Right now the slab is broken up in the corner where the line comes in. I would like to pour new concrete to fill it in.
May 19, 2017 15mm flow and return - covered whole pipe with hessian felt sleeve. 15mm mains water - laid hessian felt sleeve on top of pipe (not around) 28mm gas - wrapped gaffer tape around the pipe. I'm not convinced this is enough and so I was planning to ask he does the following. 1. wrap hessian sleeving around all of the pipes ensuring they're covered.
Jun 14, 2008 I will be running pvc water supply and waste lines through through a concrete foundation wall and am wondering what options there are to sleeve the pipes within the concrete. The structure is a garage w/ a second story studio. The foundation wall is 8" thick concrete, rising approximately 1' above grade, with a slab poured seperately.

Dec 15, 2012 I don't believe copper pipe is reactive with most foams. I have several copper pipes in my house done using PVC sleeve plus filler through an 8 inch thick concrete wall for outdoor spigots, they are more than 50 years old and do not seem to have sustained any damage.

Sep 03, 2019 Rather than encasing it in the concrete footing, why not set in a conduit of plastic drain pipe, say 40mm diameter and then the water supply line can be simply fed through that after the footings have set. Or, if the copper pipe is physically installed, slice the drain lengthways, fit back together over the copper with tape to hold it together.
When pipes are run through the walls of your foundation, they are typically sealed up with concrete, hydraulic cement, or caulk. Sometimes, they're not sealed at all! These penetrations are one of the weakest links in the foundation walls when it comes to holding back groundwater, and it's very common for them to leak water.

Aug 07, 2017 This is a 15 year old house and the builder put 3/4" copper through the basement wall (via cored hole) for the water supply - no sleeve. It's a reasonably tight fit - about a millimeter of free space. Last week we realized the pipe was broken inside the basement wall. The inside of the basement was dry but after digging down to the outside ...
Nov 19, 2003 Slope the drain pipe. Don't put either too close to the top of the slab. Don't put them "in" the slab, but in the dirt below. Use the foam insulation wrap to protect the pipe where it passes thru the concrete (concrete and copper don't get along real well, and the insulation will also help to protect plastic pipe during the pour).
PVC and CPVC-type drain, waste or vent pipe and fittings installed underground or under or through slabs, driveways, patios, foundations, etc., must be Schedule 40 meeting ASTM D2665 (or better) and identified by proper markings. Exception; Area drain piping may be SDR 35 PVC. 5.
Before the concrete trucks come, the contractor fills in the area over the network of plumbing pipes and drain lines with compacted sand. 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.

Feb 05, 2020 The most common type of pipe used for water lines under a slab foundation is copper tubing. As copper pipes age, they are prone to wearing thin and springing a leak. To repair a copper pipe you must cut the damaged section of pipe with a hacksaw, reciprocating saw
So, basically a copper pipe is coming in through the my concrete block foundation wall in the utility area of my basement, and it's leaking water at the part of the pipe that is in the hollow part of the concrete block. In turn, water gets into the hollow part of the concrete block wall and slowly sleeps into the basement via small cracks/holes.

Re: Copper pipes "reacts chemically" with concrete a "myth"? Author: Scott the Plumber (PA) I have seen too much rotted copper, unprotected, running through concrete to believe this story. As a matter of fact, copper manufacturers now produce soft copper already coated for under slab installation.

Jan 18, 2017 frank. frank. if the conductor has an outer coating, thhn, thwn, it is allowed. if the conductor is bare copper it will need to be sleeved with pvc where it leaves the slab because of the corrosive nature of air, copper and concrete at the same point. even rigid metal conduit will break down eventually when it exits the concrete.

When pipes pass through basement walls underground, ground water can leak in around the pipes and through the concrete. Many times shifting soil or a house settling can create a gap around the pipe and an escape route for water before it reaches the foundation drain pipe.

Dec 04, 2016 Leaking pipe underneath your foundation can result from a damaged water or sewer line. Mending the damaged line is not as hard as it is in locating and gaining access to the damaged line. Locating the general area of the leak is necessary; once the area is located, you will have to chisel through the concrete to the pipes in order to repair it.

Hi, are there building regs about running a plastic feed pipe through a concrete floor? i.e does it have to be ducted? I know copper pipes need to be protected or run through a conduit but is it different for plastic? If cement is tightly packed around unprotected plastic, will this have any after affects? Thanks in
Aug 26, 2009 The house was built with copper pipes embedded in the foundation for water, but to save money apparently the builder had just put bare copper pipe instead of putting it in plastic conduit. About 5 years after the house was built, the pipes started failing (in my case, it was a pipe that led to an outside faucet I never used, and I only ...
Oct 15, 2021 A professional discovers which line is leaking under the slab and where the ends come from the slab. They abandon the leaking line and start a new line above the ground, through the walls, or the attic with some creative construction solutions to conceal the pipes. Rerouting is a great option in this case, especially for one-story houses.

I'm about to start construction on a new home that will have a slab foundation and I'm planning to use copper throughout for the water pipe. Call me hardheaded, but I'm just not ready to jump on the PEX bandwagon yet, especially because of personal experience with the pin holes in the poly pipe

Mar 09, 2011 Location. Roanoke, VA. Mar 8, 2011. #6. I would suggest a epoxy to seal it. I have used hydraulic cement on a few holes but if you have alot of water coming in it wont stop it. If you do try the hydraulic cement, spray the wall and hole down with water so the existing concrete dont suck the water out of it and make it crack and it wont seal. or ...
The most obvious signs of pipe penetration issues are visible water stains on your basement’s walls. These patches will look dark and damp—or, in other words, unsightly. You may also notice water dripping from the pipes or down the walls in which the pipes are located. You may even find puddles of water on the floor underneath the pipes.
Mar 05, 2014 Pipes passing through substructure walls should accommodate movement by: a 50mm clearance all round. a sleeve, with 50mm clearance all round and suitably sealed, or. bedded pipes, connected on both sides of the wall with flexible joints located a maximum of 150mm from the face of the wall. Flexible joints should be made in accordance with the ...
