Have you ever seen the impressive terraces of Machu Picchu in a photograph? You might wonder how, and why, the people who lived there created such a feat of engineering. The answer lies in retaining walls. Retaining walls are structures built on the sides of slopes, and they’re almost completely vertical rather than rounded like a natural slope. Today, you might see them more frequently in landscaping. What are retaining walls used for? Read on to find out.
Make Land Useable
Slopes can make landscaping difficult because any new plants or other objects you place on them will likely slide down. You also must consider how you will put in these elements since putting them perpendicular into the ground will mean that stand slanted in relation to gravity. By putting in retaining walls, you can level out the surface of your yard and have a much easier time creating designs and gardens. Maintenance will also become simpler because you no longer have to worry about shifts in the ground.
Since retaining walls allow you to block off the earth at higher positions, they also work to prevent erosion. When rain falls on a hill, soil can quickly wash away. Along with it, any fertilizers or treatments on your yard can get carried off as well. You can stop the loss of soil and mitigate pollution into nearby bodies of water by installing retaining walls. Effective retaining walls act as drainage systems, and they redirect water into the proper place and assure that soil does not fall apart under the pressure of the water.
If you want to have a retaining wall put up in your property for these reasons, consider using Bedford Technology’s plastic lumber products for your building materials. Plastic retaining walls will not rot or degrade due to small organisms or moisture, and you can reinforce them with fiberglass to achieve a high rigidity ideal for large structures.
