Any property development expert worth his or her salt will tell you for fact that downslope erosion always tops the list of their concerns when it comes to property development. That explains why property developers always take time to choose which types of walls they will use for subdivisions, which types of concrete will go well for a given project and so many other important considerations such as cost of materials and labor. So what exactly makes one’s choice of walls so important? Which types of walls are ideal for different property development projects? Read on to learn more.
Gravity walls are popular mainly because of how they use their mass to resist pressure exerted by earth on them. Unlike other types of walls, gravity walls have an average height of three or four feet. They feature a wide range or materials stacked together to improve strength and integrity. A closer examination of a simple gravity wall reveals that the thickness of the wall around the base area should always exceed the thickness at the top. This is a process known as battering which is designed to improve stability. One downside that comes along with constructing a retaining walls is costs. You will certainly spend a lot as far as building materials are concerned.
Cantilever retaining walls
They are taller than retaining walls, a factor that makes them ideal for property owners who fancy privacy. They also have a start difference when compared to gravity walls in regard to thickness as they feature uniform thickness. A well-engineered cantilever wall should be able to hold back enough soil and still remain stable. Most basement rooms and underground parking lots feature cantilever retaining walls.
Sheep piling retaining walls
They are ideal for areas that have soft soils and tight spaces. The walls features use of different construction materials like steel, wood planks and vinyl. The statistics or rather the ration for sheep piling retaining walls should always be a third portion above the ground and at least two thirds below the ground. The whole construction process is long and somehow complicated as it also calls for other construction requirements like proper drainage.
Concrete retaining walls
They offer ideal support for vertically slanting slops. That makes them suitable for gardens, sizeable lawns and other outdoor landscapes. They are high built, slightly thick and high built. They also have deeper and heavier soil mixed with concrete underneath them. To that extent, they make good walls for private homes. Their solidity and resilience simply stands out. Properly built and well maintained walls hardly face problems like cracking, tiling or bowling. They also do not give in to climate induced degradation.
Block retaining walls
Block retaining walls are just as popular as the aforementioned gravity walls. They feature more in civil construction mainly because they guarantee impeccable enclosure or if you may, privacy. They fall under two main categories which include modular and segmental retaining walls. Both categories feature interlocking concrete units which use gravity to keep sliding, hydrostatic pressure and soil erosion at bay.
