The Pellet with Promise.
Thawing begins immediately.
As soon as ice is melted, slush and water should be promptly removed to prevent refreezing. The cycle of refreezing and thawing by natural weather elements can cause damage to concrete. The use of an ice melting agent increases these cycles, and are factors over which we have no control. All deicers may be harmful to concrete surfaces. Independent testing shows that these pellets contribute less to concrete scaling than other commonly used deicers.
