It’s with high impact and pressure resistance which is quite durable.The long-term pressure resistance not only can stand the weight of concrete bottom plate but also the unavoidable outside pressure and impact force during construction. For example, vehicle, worker stepping, concrete pouring impact force, etc. It … Read More »http://www.geogridfactory.com/wp-content/uploads/2022/11/drainage-board-1-2-5.png
