Other ice-treatment products we carry:

Groundskeepers Best

Groundskeepers Best Ice Melt contains a blend of sodium, calcium, potassium, magnesium, and calcium magnesium acetate (CMA), which helps to break up ice and melt it faster than traditional rock salt. It's effective in temperatures as low as -25°F and is color-coated for better visibility. Available in 50 lb. Bags.

Hot Melt

Hot Melt is specially formulated so every sodium crystal is enhanced with magnesium chloride. It melts ice quicker at lower temperatures and has a residual action so it works longer than other deicers. Hot Melt is color coated to provide higher visibility and coverage. Available in 50 lb Bags

Mag Pellets

Mag Pellets melt ice and snow at temperatures as low as -13°F (-25°C). Mag pellets are less corrosive and less toxic than traditional ice melters like rock salt and calcium chloride, making them safer for concrete, plants, pets, and the environment. They leave no residue and start working immediately upon application. Available in 50 lb Bags

Calcium Chloride

Calcium Chloride works well in very low temperatures, often effective down to -25°F (-32°C). It melts ice quickly by lowering the freezing point of water. When calcium chloride dissolves in water, it releases heat in an exothermic reaction, which helps to melt ice faster. It attracts moisture from the air, which helps it to create a brine solution that melts ice more efficiently. Available in 50 lb bags.

“The job is still pending. I can let you know more later part of next week. I do appreciate your quote, and used your company a few weeks ago for a large backfill project in southeast DC. Your company was great and helped the job go smoothly. AggTrans will be my choice for future jobs. Your personnel are great to work with, deliveries as promised, and the pricing is great also. I will get back to you later next week on this particular project.”

“Thank you for following up on the quote. Another supplier was not chosen. From time to time we need play sand. It is not often but there are times when we need it. We also need a reliable source for it as well. After I received the quote and priced it for the job the customer chose to move in a different direction. We like the service we receive from Aggtrans. Our sales rep took the time to notify us that the masonry sand had changed colors slightly. That was a great to me was great customer service. Most companies would just ship, and ad say that's the new sand and its out of our hands. We will continue to use Aggtrans because of the service we receive. The online portal is easy to use as well.”
