Maybe you’ve never thought about the sand and soil in general and its strength. It is not so powerful and we have only examples that the sand is making a pile that can be easily ruined on a small press. But, if you see the video bellow you’ll understand what the constructor workers and especially geotechnical engineers do. They develop the understanding of the soil strength and take the best of it in so many constructions that are everywhere around us.  So with a small trick and experiment showed in the video, the sand boosted with fiberglass window screen is so strong and can easily handle the pressure of the car and more! Check this out and learn more!
