Did you know that concrete bags have vents?
Concrete and other dry-goods bags have vents to prevent the them from busting open while they’re being handled. The vents are designed to allow air to move in and out while keeping the product inside. But more often than not, some of the product finds its way out. If you want to keep your work area and yourself cleaner, carry and stack the bags with the vents on the top side. Also, if you just want to cut out one corner of a bag, make it the corner with the vent. For a closer look, check out the video below to see exactly where the vent is located and what it looks like.
