De-icing
Sand and salt can be enhanced by adding a de-icing application; you can buy it in bulk and do-it-yourself or contact GRM to perform pre-wetting on site.
Wetted Salt with Liquid Calcium Chloride
At 25F (-4C), rock salt takes a full 19 minutes to embed in ice and hard-packed snow. Wetted with a 32% calcium chloride solution, rock salt immediately digs in and holds a close pattern on winter roads even when temperatures drop down to 0F (-18C). Wetted salt reduces the need for frequently repeated applications, decreasing material use by as much as 40%.Pre wetted salt application
Storing 30% to 32% calcium chloride solution in bulk tanks provides the right product for the fast, efficient spraying on rock salt as needed. Except for the equipment and adaptation methods described below, wetted salt application techniques vary only slightly from those for conventional rock salt.Spraying in the spreader truck (“Overhead”)
Load rock salt into the spreader truck and drive it beneath a spray bar containing calcium chloride solution. You can then easily spray the amount of calcium chloride needed onto the salt.Spraying during application (“Onboard”)
Spreader trucks equipped with calcium chloride tank/feeding systems allow fast and effective application of wetted salt. During application, the salt is wetted with the calcium chloride solution and spread simultaneously.Deicing application tips
When winter storms hit, correct application of pre-mixed or pre-wetted materials can make a difference in keeping roads in an easily plowable condition. They save valuable time in treating roads by preventing precipitation from bonding with the road surface.
Application tips from road superintendents who use calcium chloride include:- Get out early and use adequate amounts of road materials throughout the storm
- Don’t let ice build up under snow
- Keep snow slushy and plow it off
- Treat hills and intersections first
