For years, sidewalks have been the bane of many a snow management professional’s existence. Armed with brooms, shovels and buckets of rock salt, crewmembers tasked with keeping walkways clear spend valuable man-hours that eat into profits.

When compared to larger, easier-to-access parking lots and roads, sidewalks are time-consuming, labor-intensive and generally offer lower operating margins. They also happen to be some of the most scrutinized portions of any job. The aftershock of a hasty completion can come months later, as spring thaws reveal burned lawns and greenery from haphazardly applied sodium chloride. Sidewalks are one of the more challenging aspects of any snow and ice business.

However, technology and attitudes toward sidewalk snow maintenance are changing. Recent products and methods have increased the efficiency of keeping walkways safe for pedestrians. They have also improved profitability for businesses that make a living battling snow every winter. By planning, managing material costs and making smart investments, contractors can turn sidewalk maintenance into an attractive service opportunity.

The best solution to keep sidewalks clear is to increase snow removal efficiency to the point where having a larger crew isn’t required.

Dreaded labor costs

The biggest reason snow and ice managers despise sidewalks is their inherent inaccessibility to most motorized equipment. Many sidewalk accounts are zero tolerance; therefore a snow and ice business must clear even a slight dusting of snow.

Often, contractors solve this by hiring a seasonal crew of laborers. Led by one or two full-time professionals, 10 workers with shovels can clear a larger sidewalk relatively quickly. But even at minimum wage they eat into a job budget. Also, turnover rates tend to be high. Searching for laborers to fill job openings in the middle of the season can put a strain on your crew’s ability to efficiently complete one job and move to the next.

Therefore, the best solution is to increase snow removal efficiency to the point where having a larger crew isn’t required.

Snow removal equipment

The first place to look is equipment already owned. With a moderate investment, purchasing attachments such as plows, spreaders and sprayers to retrofit UTVs or ATVs is a great way to tackle sidewalks. Consider motorized products that offer ease of use, as well as the ability to tackle a sidewalk in just one or two passes.

For snow events that drop 3 inches or more of accumulation, snowblowers work very well. A motorized walk-behind rotary broom does a faster and more effective job of reaching bare concrete in lesser amounts of snow. These units pay for themselves through versatility, and some manufacturers have created add-on plow blades to windrow deeper snow, as well as bristles ideal for snow removal. Rotary brooms can cover a vast majority of snow events, including light dustings when blowers aren’t practical and shoveling takes too long.

Attachments turn ATVs and UTVs into all-season workhorses. Manufacturers now offer blades and V-plows with adjustable widths, covering a majority of sidewalk applications and making single-pass clearing possible. These tools make quick work of sidewalk snow removal and all but eliminate the time concerns of regular maintenance.

Ice management methods

There are many ways to spread pelletized material on sidewalks, from hand spreading with scoops to broadcast-style walk-behind and tailgate spreaders to sidewalk-specific technology such as powered drop spreaders.

Hand spreading of materials is often the last resort of sidewalk crews. It gets the job done, but employees literally control margins in the palm of their hands. It is highly subjective, as there are no guidelines available for base-lining performance other than visual inspection.

Spinner-style broadcast spreaders are popular and offer great flexibility. There is a tendency to fan material in a wide pattern, which works for larger walkways and parking lots, but not on narrower paths. Material can easily be over-broadcasted, too. This causes the use of unneeded product and can even harm landscaping. Utilizing deflectors around the spinner allows for greater control to effectively manage bounce and scatter in the desired treatment area.

Offering a higher degree of material control are drop spreaders, which are quickly becoming the preferred tool of sidewalk crews. Drop spreaders work much like they sound: the material is dropped straight down to the surface and only as wide as the gate. By controlling the feed gate and travel speed, materials can be more accurately applied to the desired area – a noted benefit for the narrow confines of a sidewalk. The results are efficient application and use of materials, which ultimately lower costs because material is placed precisely where it is needed and isn’t over-applied or spread beyond the sidewalk’s edge. This saves the contractor and the client money, since it lowers the investment and time needed for repairing salt-burned lawns. Drop spreader models come in many options, including manual and powered walk-behind units, as well as UTV attachments.

UTV- and battery-powered walk-behind sprayers are a preferred choice for contractors who have worked liquids into their ice management process. Applying brine to bare sidewalks can help prevent ice bonding, as well as make clearing snow easier after the storm. Look for models featuring hose-and-wand attachments to get hard-to-reach areas and stairs, which are some of the most difficult aspects of sidewalk snow and ice management.

Along with knowing what deicing or anti-icing product to apply, understanding how much to use is key to proper application.

Materials matter

Beyond equipment, labor and fuel costs, deicing and anti-icing materials are easily the largest expenses for snow and ice businesses. However, those expenses can be controlled through proper application and usage.

Costs generally increase as the temperature drops, necessitating the need for higher performing materials. The three most common forms of rock/pelletized materials used on sidewalks are sodium chloride, magnesium chloride and calcium chloride. Knowing when and how to use each can result in more efficient clearing and better cost-savings.

Sodium chloride (commonly referred to as rock salt) is the most prevalent deicing material, but it is most efficient at around 20 degrees F. If the temperature falls below 16 degrees, salt can be a waste of time and money to apply. Magnesium chloride melts snow to minus 13 degrees and is less harsh on vegetation than salt, making it a preferred choice as the mercury drops. It’s also more expensive, so using it when temperatures are higher needlessly cuts into margins. For really frigid temperatures, calcium chloride is considered the standard in terms of ice melting performance, but it’s also harsher than magnesium chloride on vegetation and surfaces.

Along with knowing what to apply, understanding how much to use is key to proper application. By knowing these variables, a contractor can make adjustments and track their product usage rates and costs.

Proper equipment settings ensure material is applied in a uniform layer and density. A good rule of thumb for sidewalks is 10 pounds per 1,000 square feet in an even application during average temperatures and accumulation. Colder temperatures and higher accumulations may require bumping up to 15 to 18 pounds per 1,000 square feet. Accurately tracking how much material is applied and its effectiveness can allow a contractor the benefit of adjusting through the season for each job’s specific requirements. At the bare minimum, measure each jobsite and track the amount of material used to better understand how they work and if they are being applied correctly.

Continuing education

All of the information regarding proper material placement and type, as well as equipment procedures, are of little value to a contractor who doesn’t educate his crews. After all, they are the ones who will be spreading the salt and clearing the snow and ice. Spending time with employees prior to the first winter event can play a crucial role in proper site application.

Sharing best practices and knowledge about the equipment sets expectations and improves results for the client, as well as controls costs. It’s not a bad idea to demonstrate equipment and explain proper operation, especially if purchasing a new rotary broom, drop spreader or other sidewalk tool. A refresher for returning employees is always beneficial after a long summer. Also, a trip to the site in the daylight under controlled conditions is a golden opportunity to outline and communicate client expectations.

With better tools in place, one can be confident that the job will be completed more efficiently and effectively. But just as important, solid tools can help make sidewalk snow and ice management a more profitable part of any winter contractor’s business.
