Every year, there are landslides all over the world, causing millions in damages and affecting thousands of people. In Canada alone, there is $200-400 million of property and homes destroyed by landslides every year. This is a lot of money that can be put towards other things, such as education and healthcare. So, I asked, “Can we prevent slope failures caused by oversaturation with the help of reinforcement with common vegetation and everyday recycled materials? What materials and shapes can effectively strengthen the unconsolidated soil slopes?” This project looked at how the stability of the control slope was affected by the 6 different reinforcements that were tested. Combinations of plastic or paper geocells, mesh and azalea seedlings were used to strengthen the slope. The slopes were tested using a showerhead to mimic rainfall and were measured to see how long they would last under the onslaught. I hypothesized that if the water pressure and weight could be reduced, then slope failures could be prevented. The results supported my hypothesis as the geocell and mesh combo was the strongest, which had been designed to reduce the amount of space where water could get in and also to force some grain to grain frictional contact. In the future, I believe that this design could be applied in the real world, as a simple and cost friendly method, but perhaps with stronger materials to counteract the amount of weight in a larger slope.
