A Secret Weapon to Combat Road Salt Damage

Bacteria, which have been working for millennia as nature’s stonemasons, could soon be enlisted to help neutralize the destructive effects of road salt. According to the Transportation Research Board, it takes about 10 million tons of road salt to keep roads safely navigable in the winter. And while it’s certainly an effective method for staving off snow and ice, around this time of year, we start to see the toll it takes on our infrastructure in the form of cracks, potholes, and bumps.

Saving Sustainably: Installing Trim and Siding

Editor’s note: This is one in a series of blogs detailing the construction of a net-zero energy house in Point Roberts, Washington, by an owner-builder with relatively little building experience. A list of Matt Bath’s GBA articles can be found at the bottom of this page. You’ll find Matt Bath’s full blog, Saving Sustainably, here. If you want to follow project costs, you can keep an eye on a budget worksheet here. With a break in the weather, it was high time to install the siding. The Tyvek water-resistant barrier (WRB) I’m using should be protected by siding; it will break down…


Midwest Floods of 2019: The Latest Disaster to Learn From

[Image credit: NASA Goddard Spaceflight Center] The catastrophic flooding in Nebraska and other states along the Missouri River has brought back painful memories of major floods like those in 1993 and 2011. We know that floods are becoming more frequent and causing far more damage. The National Climate Assessment has warned that floods are more likely to occur in the Midwest as the climate changes. Bill McKibben, in an interview with ThinkProgress.com, pointed out that Nebraska’s “current trauma is part of everyone’s future.” The flooding in the Midwest is the latest in…
