The Perfect Construction Site!

Posted on December 21, 2017 by Ben Dalsing

As a construction worker, I like working outdoors when the weather is perfect – 60 degrees and dry. We all know as Minnesotans, North Dakotans, Canadians and Mid-westerners that you may only get a few dozen days a year with those particular outdoor working conditions.

Fresh concrete needs those perfect weather conditions, but cured concrete is resilient to all types of weather conditions. Outdoor construction sites have no control over the weather while pouring fresh concrete, bringing with it a host of difficulties.

Difficulties with pouring fresh concrete outdoors

  1. Wet, muddy, frozen or snowy site conditions make it difficult for people and equipment to move around a construction site.
  2. Rain is bad for fresh concrete. Rain can ruin the screed finish and prevent the face of the concrete from getting hard, causing low durability.
  3. Wind and sun are bad for fresh concrete. Wind and sun can cause accelerated drying of the concrete surface which can lead to drying shrinkage, cracking, and low durability of the concrete surface because the water evaporates before the cement can use the water for curing.
  4. Cold is bad for fresh concrete. Curing concrete is based on time and temperature. Higher temperatures equal faster curing. Fresh concrete will not cure in freezing conditions.

How does Wells Concrete manage these changing weather conditions and pour concrete year round? By pouring concrete indoors. All four Wells Concrete production facilities pour concrete indoors, unaffected by the changing weather and seasons.

Benefits of pouring concrete indoors

  1. A temperature controlled indoor environment gives us “t-shirt weather” year-round for pouring concrete.
  2. Heated rock, sand and water for mixing fresh concrete; no matter how cold it gets outside our fresh concrete is toasty warm.
  3. Accelerated curing using form heaters. During curing, the form heaters raise the temperature of the concrete to between 90 and 140 degrees to ensure high early strength.
  4. No wind, rain, sun, cold or snow to interrupt pouring fresh concrete.

What is the perfect construction site? Indoors!
