of the country
you’re in, you could very well be coming off one of the most trying
winters in recent memory.
With snow that wouldn’t stop and ice melt supplies that
shrank faster than the ice, it may be a relief that you survived. But as
you look out upon your lush green grass and sun dried sidewalks, I hate
to say you better be planning now for next winter, and the first thing
you need to do is throw out your book on how you used to do things.
What you need to realize today, is that as hard as it
may have been to get the product you needed to fight last winter, it
could be harder this winter and it hasn’t even started snowing yet.
After coming off of two years of very mild winters
nationwide, ice melter stock supplies had shrunk considerably with less
being purchased by end-users and distributors.
Then in many parts of the country it started snowing,
and didn’t want to stop. The aftermath is that more than likely your
supply is depleted, as is your distributor’s and the manufacturer is
scrambling (if they’re smart) to refill their exhausted supply.
The distribution pipeline is empty and the demand is
high. No one wants to get caught out in the cold again.
With the potential for another shortage in ice melter
supply, and no idea what the next winter will bring, now is the
opportune time to reassess your de-icing strategy. The days of throwing
salt at it and if it doesn’t melt, throw more salt at it, are dwindling.
Labor cost, product cost and environmental pressures
have all been pushing for a new way of doing things. The good news is
there are new tools available for your winter toolkit and they’re easy
and save you money.
If our goal is to prevent ice from forming,
incorporating liquid de-icers into your winter toolkit is the fastest
way of achieving this. Applying liquid de-icers on your sidewalks and
parking lots ahead of a storm increases your ability to fight the
formation of ice before it
starts. The
more ice you can prevent, the less chance you have for a slip and fall,
the less ice melter is required after the storm to cleanup, and less
labor is required to maintain your facility.
Liquid ice melters are not new, nor is the concept of
anti-icing – preventing ice before it forms. In fact, liquids as anti-icers
have been used by state departments of transportation across the Snow
Belt since the
1980s; however they are still a relatively new concept for the
maintenance of sidewalks and parking lots.
Championed by a growing number of progressive DOTs from
various states and counties across the US, the premise is amazingly
simple. If ice melters need to dissolve from a granular form to a soupy
brine to melt ice, what if we just started with the brine? And if the
most important
part of the ice melting process is breaking that bond between the ice
and the pavement, what if we could prevent that bond from forming in the
first place? Would this significantly impact our ability to keep roads
clear? Would this reduce our cost structure? In a word, Yes.
Applied from the backs of large liquid tank trucks down
select highways in the U.S., you can see salt brine solutions applied
ahead of winter storms. The dissolved salt provides a temporary barrier
over the pavement, preventing the bonding of ice to the pavement
requiring less ice removal labor, and reducing the amount of dry product
that would have been applied after the storm to melt already formed ice.
As anti-icing practices grew, it was discovered that beet sugars added
to the brine would help keep it on the road where it was sprayed rather
than drifting into runoff areas, and prevent the salt brine from drying
out and dusting, vastly increasing its long term performance.
Highway maintenance teams were able to apply product
further ahead of the storm, reducing over time hours, before and after
the event, and cost numbers began to show they were reducing salt use
significantly while maintaining clear roads. One pound of salt applied
ahead of the storm was doing the work of four pounds applied after the
storm. With hundreds of miles of roads for any one DOT branch, these
numbers added up quickly and converts continue to spread.
With DOTs having laid the groundwork with years of field
testing and with the recent development of equipment for applying liquid
de-icers cheaply and easily to sidewalks and parking lots, the winter
tools available to the building maintenance team have increased
significantly.
Although liquid de-icers are not a replacement for your
dry product, and don’t be mislead by those who will imply that they are,
liquids added to your winter toolkit will significantly reduce the
amount of dry product used to maintain your facility, and reduce your
costs overall. So as you survey your empty salt storage area this
summer, and contemplate how best to prepare for the coming winter,
remember the salt you wish you had last year so you can better prepare
for the future.
