Comparing estimate of sewer line repair via tunneling under house
|
|

| Location: Miami, Florida
Property location: About two miles from Atlantic Ocean, soil is sandy.
Property is single story, on monolithic concrete slab 8" thick. Via video
inspection determine line is broken about 5 feet inside from an exterior
wall probably directly under a cabinet in the kitchen, with no replacement
tiles available. The line is broken near an elbow so using a resin liner
solution is out. Had another plumber came by but he thinks he will need to
open up a hole 48"x48" under the cabinets. He will have to use a large wet
saw to cut the hole under and probably will damage the cabinets, and with
a lot of mess, and that will be $1800 as well, plus patching the concrete
slab,
plus redoing some cabinets, and new tile work. Plus if they work inside one
of us has to take time off to be at home, a two day off will also end up
costing
us additional money.
Had two drain companies came out and both recommend tunnel
under house.
Roto-Rooter estimated $1800 excavation + $900 pipe repair. The $1800
excavation cost is based on a $180 per foot basis. Since the location is
around 5 feet in, they figured 4 feet deep, 5 feet in, and an extra foot for
manuever will add to 10 feet. However, if there is a footing to cause them
to dig deeper than originally thought (I am pretty sure there is), or they
hit the water table (yes they probably will...) or the location is not
pinned down and they have to dig further to find the break (and that may
happen too...), it will be however long they dig times $180. So I figure
conservative estimate will be to figure 20 feet, which will mean $3600 +
$900 = $4500. I asked them how they will back fill and they told me they
will put the original dirt back in and it should be OK. The digging will be
done manually. They did not say whether there will be any permit fee or
whether they will get a permit or not.
The AAA Rapid Rooter came by, and their estimate is totally different. They
told me their charge is $7500 minimum. Minimum meaning they don't run into
complications. I asked them what they included, and they told me it
included using a "vaccon" truck to dig the tunnel (not manual digging), they
add water and literally "suck" the sand out and form the tunnel, the actual
pipe repair, permit fee, engineer to come out to see the soil sample is
suitable for excavation of this nature, backfill with a truck shooting wet
sand (may mix some cement in) into the tunnel. The total will be $7500.
They will not provide an itemized breakdown since some clients used their
estimate to get insurance money but never do the job.
So drastically different approach. Machine digging with water versus manual
digging. Manual backfill with excavated dirt versus shooting compacted
sand. One job is about twice as the other.
Any idea which one is more "safe and sound"? I have the feeling manual
digging is
less damaging and involve less disturbance to the soil and can keep the
tunnel size smallest, is this right? But backfilling with the original dirt
concerns me. Not sure how you can backfill the void that is above the
footing back without some sort of pressurized method. Both are reputable
companies.
I am thinking one possibility would be to use Roto-Rooter to do the repair,
and see if they will come down on the price if I ask them NOT to back fill.
I will back fill myself and see if I can find a subcontractor that will do
the wet sand shooting back fill. But will this work? They can't pull the
permit if I am going to do part of the work myself?
Any advise?
I am interested to know: Which approach is better and safer?

Tough to answer, even though you offered a lot of information.
I have a couple of problems with the story line. First, the broken "ell" or
1/4 bend that is supposed to be 5' in yet still under your kitchen cabinets.
Even with a 5 1/2" brick ledge and a 5 1/2" exterior wall (usually 3 1/2")
and a standard 24" deep cabinet, the farthest a "normal" cabinet could
extend in from the outside wall line would be about 3'.
Assuming the break is actually at 5' inside the structure my first choice
would be to go through the floor. The "$900" fitting repair is just someone
throwing a figure at you. If it's PVC the parts for the repair will be less
than $20. The money is for what it's going to take to gain access to that
fitting.
I'm not sure why there would be a 1/4 bend at that location but there's no
reason I can see why the cabinets cannot be protected. Actually, any
reasonable prefessional would cover the entire area with plastic and also
create a small plastic enclosure over the work area. The only finish repairs
that you should need to address would be the flooring.
OTOH, there would typically be a 1/4 bend at the point where the horizontal
waste line turns vertical under the exterior wall. If this is the location
of the break it is NOT 5' under the house. With a standard brick ledge it is
7 1/2" -8". This break I would handle from the outside of the structure.
And if nothing else for Christ's sake, call a _real_ plumber would ya'?
Roto-Rooter?

Bob:
Thanks for answering.
The break is about 50" from the inside of the exterior wall horizontally.
The exterior wall is 8" thick, so the total distance is about 58" so I said
5'.
My kitchen cabinets and counter is arranged in a Ushaped configuration. One
edge of this "U" is along the exterior wall, the problem area is not below
the exterior wall cabinets but below the other side of the cabinets, which
actually butts up against an interior wall, on the other side of this wall
is the garage.
You might wonder, why not open a hole on the garage floor and access the
pipe from there? First, the garage floor hole will still be 36" to 48" from
the problem area, and second, I looked at the plans for my house and it
showed a footing under that wall. I don't know why. It showed a footing
along all exterior wall and along the interior walls in the garage. May be
the garage slab was poured separately, I don't know.
I did have three plumbers come by, including the national chain "rooter"
companies. The "real" plumber cannot tell me where the problem is exactly.
There is no way to know where to punch this big hole. With the tunneling
method, location is not as critical. The local plumbers, one told me to try
a resin liner (which I did some research and had someone come by and no go
because the problem area is near an elbow), and the other one told me I need
to get a concrete company by to first open up a hole in the kitchen to
expose the PVC pipes, then he can get to work. They just did not seem
equiped to deal with a nasty problem that I have.

I assume you had the line scoped (video) to know the location of the break.
Yes?
If so, the company that scoped it would have marked how far down the line
from the cleanout. Knowing that information, and using an inexpensive cable
locator, a plumber can run his sewer cable to the pre-determined distance
and find the end of it. Voila! Exact spot found.
I have made similar repairs in the past and I have always tried to get
"others" to handle the concrete demo.
It keeps my guys happy because jackhammers are no fun.
And it keeps the customers happy because paying plumbers to do laborers work
is no fun.
Just remember that the objective is to obtain access to the leak.
A trained professional will have to determine the most practical for your
situation. I think $7500 for the situation you have described so far is
excessive. A couple thousand should be closer to the final bill.

| A couple of things here.
There was one KEY WORD you mentioned that makes your decisions a
no-brainer.
One guy tells you...we'll refill with the original dirt - it SHOULD BE
OK.
The other guy tells you, "we're hiring an engineer". Immediately, you
know that the guy hiring the engineer is the guy to hire. Even if his
price is much more.
Frankly, SHOULD BE OK translates to WILL PROBABLY BE OK FOR AT LEAST A
YEAR...THAT'S HOW LONG I HAVE TO WARRANT MY WORK. (wow...huge red
flag, huh)
So how much is it going to cost you to when the soil shifts and that
slab crack in two where it isn't supported properly with soil? If you
hire the first guy, call a house moving company and find out how much
it will cost to put your house on supports while an excavaton company
comes in there and rips up the old slab so they can pour a new
slab...and then reconnect everythign to the house. You shouldn't have
to live in a hotel for more than a month. That's going to cost a lot
of cash though. You'd probably be better off burning the house to the
ground and building a new one.
Hire the guy who used the word "engineer". If it costs more, trust me,
it's ONLY costing you more NOW to get the job done right..

| What's the frost line in FL ? 4' seems Ok.
Anyway you look at this I agree with BB. Burn it.
I've hand dug 13' ft. to reach a sewer line, its not that hard
depending on what shape you are in. 4 hrs work for me
back when and that was clay.
Hire a couple of bruisers from the local religious crack
rehab center ( no shit, these guys are grateful for hard work)
I've used them and have been told they would of done it free.
They felt great they said just to sweat again.
I hated to give a price on digging. I never knew what I'd
hit underground. Electrical at 30,000 volts to digging
a 12" trench and finding a refrigerator under ground, dead
bodies or bolder Colorado. You never know.
You must know how to back fill also. The code in your
AO may call for screening and tamping.
Let us know what happens.

"The line is broken near an elbow so using a resin liner
solution is out. "
MC,
Not true at all.
CIPP (cured in place pipe) is relatively new to the residential side of
plumbing whereas some municipalities have been using it for some time now.
Many plumbing companies have not fully embraced the various trenchless
technologies yet, therefore knowledge of it is often incorrect. I
personally haven't made the leap into trenchless yet. When I can afford to
purchase the equipment, I will. The benefits far out way the traditional
methods WHEN trenchless is an option. In many cases a backhoe, some helpers
with shovels and a wide open area is a less expensive option. In other
cases where the excavation itself would do more damage to property, cost
more etc., tenchless would be the way to go.
I'm not abosolutely certain as to the location of the 'break', fittings and
or 'turns' that might be along the way, but I'm certain a CIPP job would do
the trick with minimal damage to your property and most likely save you some
dough as well.
Here's the video page of the MAXLINER process:
http://www.maxlinerusa.com/video/video.htm
The main website:
http://www.maxlinerusa.com/index.htm
Also checkout:
www.ultraliner.com
Ultraliner's material is an alloy, different from the resin, but is still
considered superior. Also, I'm not absolutely certain ultraliner can be
applied to a residential situation. So you'll need to ask about that.
Contact Grant at GrantWhittle@ultraliner.com He's head honcho of a bunch of
trenchless related associations and NASSCO and VP at ultraliner. Grant is
extremely knowledgable and is an expert in the area. I've corrosponded with
him several times regarding various things in and around the trenchless
industry. I'm sure he, or someone there can point you in the right
direction about lining your damaged pipe and possibly to a contractor in
your area.

| I have already contacted several trenchless repair companies. Most of them
told me straight that it needs to be 3" minimum size for it to work.
The only one I was able to contact and was local was
http://www.formadrain.com/. The inventor of that particular technology
happens to be in town and came by with a video inspection, and told me after
the investigation they cannot do it because of an elbow section that is
curved. He showed me a section of the fiber glass composite pipe section
that is very very strong. I think if it had worked, the quote he gave me
was like $1500 to $2000. He told me he is absolutely sure in my case
trenchless will not work. He is the one going around the country training
people in using this technology.

| *Most of them
told me straight that it needs to be 3" minimum size for it to work*.
I thought for some reason we were talking about a 3 or 4" line. I was under the impression you were having a mainline problem. Sorry.
Well if it's as you say less than 3", then were talking about a 2" or maybe even 1-1/2" drain line. Big difference Personally, I've done my share of slab repairs, as I'm sure many of the other plumbers here have, and unless there's a probelm with the foundation getting in the way or some such thing, this job (should) be easy for a professional who knows what he's doing. However, a pro does run into unforseen things also.
You seem like the type of person that would already know this, but especially for this kind of thing DO hire a licensed, reputable company or individual.
Hydro-excavation vs. hand digging is a pricey thing. hydro-ex. is mainly a benefit to the workers (it's a back saver) and can typically reach areas that a backhoe can't and it's faster. As I see it, you wouldn't want to use a backhoe or some such large digging machine in your situation, but then again I'm not there on the property either.
Honestly, this SEEMS like a straight foward jack-hammer, hand dig, repair, back fill job. Unless of course the soil is contaminated and needs to be replaced with sand or some other suitable replacement. That's where there could be a problem. If all the soil that surrounds the pipe has been permeated by the waste leak isn't removed and replaced with fresh soil and then properly compacted, you run the risk of undesired settling and shifting of the pipe, the foundation, slab or all.
You may want to get an estimate for the work to be manually done from the garage area and then have a different company backfill with slurrry (if that's allowable by the code) or whatever is recommended . By no means though, replace the original soil IF it is non-compactable.
As far as those cabinets go, unless there's some factor we're unaware of, no damage should be done. They should be easily removed. If you decide to go through the kitchen, and are unsure if the guy(s) doing the work will not damage the cabinets, you should consider removing them on your own.

Bob:
I am now exploring the option of cutting open the kitchen floor. So far the
concrete companies I contacted told me it will be very dusty for a long time
with a lot of water sort of like "starting a motor cycle in a mud puddle".
So I wonder do you know of a way to cut the concrete floor (probably be
rebar in there too) that will minimize dust and splash ( I am willing to pay
more for that), furthermore, I was also told if I replace the PVC pipe and
then pour concrete to patch the floor, the concrete when cured will settle
to crack the pipe. Is there any truth to that?
Thanks in advance,
TIA

Start working now. Get a damn hammer and chisel and start.
Before you know it, you are done.

I think someone is making a bigger deal out of cutting this hole than it
really is.
Yes, chipping the concrete will create dust. That's why the area should be
encased in sheets of (thin) poly. Cover everything in the room with poly,
sort of like you were painting. Then create a smaller, say 8'x8' work area
that has poly from floor to ceiling. This will take all of 45 minutes.
Or you can simply saw through the floor with a wet saw and a diamond blade
but this requires water and will make a much bigger mess than just chipping
out the floor. However, there are companies that specialize in concrete
demo. For hole coring and large projects I use a local company called Holes
Incorporated. I have seen them do some things with concrete I wouldn't have
thought was possible. Perhaps the link below can steer you in the right
direction for your own area.
http://www.holesinc.com/about.htm
Once the hole is there and the repair is made all that is necessary is to
either make sure that you replace the rebar that you cut out by either
tieing into existing rebar or drill dowels into the demo'd area. That will
be sufficient for ensuring that the new concrete doesn't settle.
A little context for slab on grade projects - The critical parts of this
type of foundation are the footings (beams).
Beams are placed under all the load bearing walls. This will include all the
exterior walls and many of the interior. The beams are the portion of the
slab you _don't_ want to mess with. This is why I'd rather avoid going in
from the outside if possible. You will be under-mining the load bearing
ability of that exterior beam. And you certainly do not want to cut it.
You want to do everything possible to preserve the structural integrity of
all the beams.
The flat areas between the beams are simply "flooring". They are just a flat
surface to put finishes on and to walk on. There is no structural
significance to a flat area between footings.

| last one i did i used a sledge hammer and my hammer drill (big one) I was lucky slab was only like 3 inches thick then i hit sand. once you hit sand it get EASY. Just dig out sand to undermine the stuff you want out then hammer with sledge from inside of hole out. It cracks with no support under it wicked easy.
