It is essential to be familiar with the components of retaining wall components in order to construct any type of fence or wall correctly. It is difficult to construct a wall that will last in the future without a basic understanding about what constitutes a wall. The components are easy to understand: concrete forms, posts or beams, and either flagstone or wood depending on the climate. In no time at all you can have your custom wall built to perfectly suit the conditions and needs of whatever it is that you wish to enclose.
There are two major components of a retaining wall system, the primary frame and the bottom or channel framing. A frame is usually composed of individual posts or tubes that are attached to one piece of concrete or another structural member. Each article is usually supported by steel posts or metal rods bent into the appropriate configuration. The bottom course, also known as the ground level or work surface, is the foundation. The upper level, also known as the working surface, is the grade of ground above the work surface. The requirements of the application and the surrounding conditions will dictate the design of the wall.
Concrete is more suitable than steel to keep walls in place when the earth pressure rises. Concrete is more durable that steel because of its resilience to pressure, and its ability form into a perfect seal to protect soil particles and other contaminants. These properties make concrete an excellent choice when it comes to holding ground walls in coastal areas where high soil pressure is a concern.
Concrete is used both as a foundation and support for a structure. The foundation’s main components are the walls which can be reinforced or poured before the structure and the footing which rests directly on it. Without a foundation, a concrete retaining wall must be poured onto an existing basement or foundation. This construction method is more costly than traditional poured concrete foundations but produces a stronger, impervious wall that is also stronger. Skid foundations are another option for foundation structures. They can be placed directly on the ground and are more environmentally friendly.
In cases where the foundation cannot be used, materials such as gravel or crushed stone may be used for countertop edging, while other methods such as concrete retaining walls may be constructed on an angled ground plane. Grading of a hillside may also be used to create a more level surface. For concrete walls, a basic style involves the use of two parallel slabs of concreted material, connected by a supporting beam or block. The most common styles include flatbed, parallel bed, cantilever, and relieving platforms.
The wall and the wall’s back are the most important parts of a retaining wall. The vertical distance from ground to top of the wall is called the back wall. The vertical length of the wall’s wall is called the heel slab. The heel slab, also known by the slagboard, must be securely connected to the earth or another concreted structure. Concrete must be poured at its base. Then, piers and ladders can be used to raise it to the desired height. As the wall is raised, various strategies such as cantilevers, parallel beds, and heel slabs are used to provide additional lateral support and to adapt to changing ground conditions.
Relief platforms are a key part of many concrete retaining wall designs. These platforms, which are directly placed on the ground, allow water to percolate through concrete and drain away from walls. A water bearing design is usually required for pressure relief platforms. Cantilever relief platforms provide additional lateral support while relieving platform designs offer more space for expanding concrete in their interior. These features can help you save significant money on your concrete retaining wall project.
Concrete retaining wall designs can be made with a variety concrete elements. These structures can include concrete slabs, concrete wedges and concrete relief platforms. Determine your needs and research the options available before selecting the most appropriate concrete retaining wall for your project.
