Concrete, like asphalt paving, needs to be constructed during mild to warm weather. For Minnesotans, that means between early May through October. Temperatures need to be above 35 degrees for 30 days after the concrete is installed. In addition, concrete pavement shouldn’t be constructed when temperatures are above 85 degrees. At Richfield Concrete, our concrete crews are at work throughout that season to create concrete projects for Minneapolis St. Paul metro area homeowners.
