We are planning a manhole rehab project. What are the
advantages of Barton Southern’s grouting technology
vs. other common renewal methods? |
| |
All renewal methods have their place in certain situations.
Our experience has been that chemical grout injection
has certain advantages over manhole liner systems for
several reasons. Some of these are:
1) Chemical grouting actually stops the leak. Other renewal
methods simply cover up the problem (the Band-aid approach).
One thing to keep in mind about manhole liner systems
is just because you can’t see the leak behind the
liner doesn’t mean that it is not still leaking.
2) Chemical grouting fills voids. Liner systems cover
the inside wall of a manhole, but do nothing to fill the
void behind the manhole that is often the source of the
leak. Liner systems do not prevent voids from growing
and potentially leading to sink holes. In many cases,
we have found that after injection grouting, the manhole
no longer requires additional renewal methods. |

| 2.
I have ozone treatment tanks. Are your chemical grouts
safe for use in that environment? |
| |
| Yes.
In addition to being ANSI/NSF 61 compliant, our hydrophilic
polyurethane grouts are safe for use in ozone treatment
basins or any other type of water holding tank. |
| |
|
| |
| 3.
Why should I choose renewal over replacement of my sewer
system? |
| |
| According
to a study published by the U. S. Environmental Protection
Agency (Clean Water Needs Survey, 1996), an estimated
$90 billion would be needed to rehab the nation’s
infrastructure to an acceptable level versus an estimated
1-2 trillion dollars to replace the existing infrastructure.
From this we can extrapolate that infrastructure renewal
projects cost only 5-10% of what a total replacement would
cost. Modern renewal technologies (i.e. chemical grouting)
are capable of returning a structure to "like-new",
so why risk the cost and hassle associated with replacement? |

| 4.
What kind of warranty does Barton Southern give on their
work? |
| |
| The
industry standard warranty for materials and workmanship
is one year. This allows the repaired structure to go
through one full year of thermal expansion and contraction.
If defects are not present in the first year, the repairs
should last for the life of the structure. |
| |
|
| |
| 5.
Are the injection grouts you use flexible? In other words,
will they remain effective as the structure moves due
to natural settling and thermal expansion due to the freeze/thaw
cycle? |
| |
| Yes,
hydrophilic polyurethane resins are specified in applications
where the structure is subject to thermal cycles. These
resins are designed to bond to concrete & remain flexible
so that the repair is not jeopardized as it moves. |
| |
|
| |
| 6.
Is Barton Southern equipped to handle high-level projects? |
| |
| Absolutely!
We’ve made a name for ourselves on such large, high
visibility projects as nuclear power plants, dams, and
international airports. We are experienced with the procedures
involved with obtaining security clearances for our crews
when requested by customers. We also have the specialized
tools, gear, and heavy machinery needed to tackle any
high-level project. |

What benefit does a professional infrastructure repair
contractor like Barton Southern have over my in-house
repair crews? |
| |
| Barton
Southern is experienced in using a variety of repair techniques
and product formulations to provide a custom repair solution.
Our years of experience allow us to adjust our repair
plan if needed as we work to insure that your facility
is getting the highest quality, most cost effective repair.
We have a warehouse full of specialized materials and
equipment to help us complete your project. Our crews
are trained for special repair situations such as Confined
Space Entry. The chemicals that we use (and many other
similar type chemicals on the market) are professional
grade and are best installed by trained professionals.
Product characteristics like precise pot life and critical
mix ratios make them difficult for the untrained person
to use. In fact, untrained workers could do more damage
than good in certain situations. |
