Landscape design is not only for beautiful gardens or outdoors, they serve very functional purposes as well. There are many factors such as rain, wind and even gravity that can cause issues for small backyards and even big landscapes. Therefore specific types of engineering are also required in designing a garden space to withstand all or at least some of these harmful elements. One key aspect when it comes to the outdoors is soil, and how it is used to create the perfect setting. However one of the many issues faced by landscapes is erosion that can damage and even clog certain areas of the terrain. This would especially be an issue if the land is at an incline or a slope. Retaining walls are one method used by designers and landscapers to combat such erosion. They are also used as decorative additions and as boundary lines as well. Depending on the conditions of the soil and the terrain, the types of structures built will greatly differ. In areas where there are considerable amounts of weight on top of the soil that needs to be contained, reinforced walls may be required. Gravity walls are another type which uses the natural setback of the soil to give it strength and stability. There are many options available for builders in creating these beautiful and functional structures.
Sandstone slabs, concrete, repurposed wood, treated wood and natural rock is some commonly used items to build these structures. Concrete blocks seem to be the most common method used these days. There are said to be very durable, low in maintenance and easy to install. However, they will be difficult to remove or adjust if your decisions have changed. Poured concrete is also a modern option used in strengthening areas where there are slopes or dangers of erosions and landslides. However they need to be supported with iron rods or wire if they are to hold in place, if not they are prone to cracking. Natural rock and types of stone are another popular addition used in garden design. Not only do they add to the strength of the functional structure, but their natural colour and textures really work well for designed spaces. They also last a lifetime. Gabion is an olden day method where stone, rubble or rocks are encased in a wire mesh or cage. These are very popular in eco friendly structures as almost any kind of durable material can be used to fill in the cages. Timber or wood is also commonly used however their propensity to decay and short life span is actually working against them. These are some of the techniques and material that can be used for building these structures; however a popular alternative these days are using recycled material such as old tires and even plastics in a compressed state. Therefore do your research before settling in for a method as there are many new eco friendly low priced alternatives as well. See this post to find out more details.
