Does This Footing Need a Capillary Break?

As he works out the details for a new house, Jason Huffine has become concerned about the potential for trouble in applying a capillary break between the concrete footing and the foundation walls. A capillary break would prevent the foundation—in this case steel-reinforced, concrete-filled block —from wicking up moisture. Huffine’s general contractor isn’t familiar with this technique, and the two of them wonder whether the capillary break would weaken the connection between foundation and footing. “Though I’m as green around the gills as one could be and learning as I go, that sounds like a good question to me,” Huffine…

Photo: Alan Stark / CC / Flickr Does the addition of solar capacity on the grid cause an increase in air pollution? A North Carolina newspaper argues that it does. Earlier this month, the North State Journal pointed to an air pollution application from Duke Energy for gas-fired power plants it operates in Goldsboro, North Carolina, as evidence that solar energy causes an increase in nitrogen oxide (NOx) emissions. The Raleigh newspaper quoted Duke spokeswoman Kim Crawford as saying that reductions…
