Few things have more potential to negatively impact a concrete contractor than the weather. But now Holcim has released an enhanced version of its free weatherAPP which uses a GPS locater to provide a four-day forecast for any jobsite on earth. It generates the favorability conditions for placing concrete by comparing weather conditions and evaporation rates with concrete data. The enhanced version allows contractors or concrete producers to update the concrete temperature (in either Fahrenheit or Celsius) based on conditions and provides complete and timely access to this critical data. The weatherAPP is supported by Android, AppleiOs, Windows 7 Mobile, and certain Blackberry devices through Web browsers. For more information on the app, please visit www.weatherapp.us.
