An all-weather product specifically developed to support and extend the construction season into the winter months.

WeatherMix® extends the construction season with its range of specially designed concrete mixes that work with temperature – accelerating setting time in colder weather and slowing down in severe heat.



Superior Cold Weather Concrete

WeatherMix® is specially designed to tolerate colder conditions than normal concrete.

It also accelerates setting time, which provides early protection against freezing at subfreezing temperatures.
