who else plows a parking garage?

    I picked up a parking garage from a person I do other business with. This is the first winter with the parking garage for him. I knew it would be a pain, especially since no salt is to be used. The last storm was a wet snow and I spread a lot of sand to keep it safe on the top floor. I equipped a truck with a poly cutting edge also. What tips can you give me to make this go as smooth as possible?

    an area needs to be designated for stacking

    a skid steer should be available if accumulation consumes your stacking area

    make sure side of parking garage is roped off and manned when loading off of roof

    use calcium chloride instead of salt to remedy freeze- thaw cycle to concrete joints

    Isn't c.c. highly corrosive to the support beams?

    Calcium chloride is used in concrete mixes to help speed up the initial setting, but chloride ions lead to corrosion of steel rebar, so it should not be used in reinforced concrete

    in large structures such as concrete parking garages , buildings and heavy highways , the rebar has been coated with a green epoxy for the last 10-15 years that I know of , a corrosion inhibitor

    Urea will work until 15 degrees and it does not contain chlorides, so it is less corrosive and safer for use on concrete containing rebar.

    Just my .02¢

    ill check into the urea, might work for some days. any other tips on plowing parking garages besides ice melting?

    As stated, no. But it will chemically interact with portland cement.

    Not necessarily.

    I plow a ramp where salt is used. It also has a urethane coating to prevent the chlorides from getting to the rebar.

    As for stacking, you better make sure that you can stack snow in one place as well as be ready to move it regularly. Most of the time piles are only allowed for a limited amount of time because the design is for weight to be spread out, not all in one corner.

    You need to speak with the owner and find out if, where and how much snow can be stored until removal.

    You need to speak with the owner to find out what can be used for de-icing. Have them check with the engineers who designed the ramp. It would be a good idea to ask them about where snow can be stacked as well.

    You need to do some homework yesterday before you have issues.

    1st, how old is the PG

    2nd, do you know if the rebar is protected?

    3rd, what about the rest of the steel?

    It has long been known that chloride ions from deicing salts, sea spray, sea water, marine fog, admixtures and mixing water can permeate concrete. When chloride, oxygen and moisture come together on the surface of unprotected steel, corrosion will result. Rust formation on rebar places pressure on the concrete that can result in cracking, spalling and delamination. The loss of bond between concrete and reinforcing steel and the loss of rebar cross-sectional area both have the potential to result in serious structural problems.

    Companies and trade organizations with expertise in concrete construction technology are familiar with options available for corrosion protection in new or rehabilitated structures. With support from these experts, each end user should determine whether or not application of chloride-based deicers is appropriate for their given situation."

    That is a quote from http://www.oxycalciumchloride.com/ I would consult a professional engineer to protect your rear. This isn't a case of "well he did it, why can't I"

    Watch out for the Rubber Expansion sections.....Becomes costly to repair if the rubber is ripped out.....payup

    Also.Potassium Acetate is the closest you are gonna come to "safe" to use on concrete.....But its expensive....
