When we moved into our current house, (almost six years ago) I noticed cracks in the concrete driveway. Not just expansion joints, but cracks and a few small holes. I got to reading how water can freeze and plants can grow in the cracks and make them bigger. If these cracks and holes are not maintained properly, it can result in irreversible damage. I originally used a special silicone caulk made for sealing concrete and masonry. It worked but, after a year, it started coming out of the cracks. The caulk cost about ten dollars a tube and I thought I would try hot glue instead. The hot glue has held up over two years. In this Instructable I will show you how I use hot glue on the expansion joints, cracks, and small holes in my concrete driveway.
