There are many different methods of pier installation. One way that is growing in popularity is the use of fixed pier structures rather than removable piers. The fixed pier is simply a structure that extends out into the water from a specified location where a boat dock or other location is formed and the posts are anchored into the water.
Fixed pier installation requires the careful planning and coordination of local government agencies, including water levels, shoreline and other issues that must be considered. Depending on the site and how much water is available, certain types of permanent piers may not be able to handle the weight and have to be removed. Others may have to be moved in order to meet current water levels. Once this is decided upon, plans for the permanent piers can be discussed with the local council and engineering services.
When a local council or engineering service chooses to use foundation piers as a means of permanent pier installation, there are several factors to consider before making a final decision. If the foundation pier is being chosen because the water will be lower than the surrounding ground, it will be important to determine how much weight the foundation structure can safely bear without stress. This will be different depending on the width and depth of the area where the foundation piers will be anchored. The amount of stress that the foundation structure can withstand will depend largely on the type of pier chosen and the size of the pier.
In areas where the water is relatively flat, fixed piers can usually be constructed by using standard steel posts and beams. For areas that are rougher or more complex, concrete is used as a foundation piers alternative. If choosing a permanent piers design, there are other things to consider as well such as the method of anchoring, whether or not the structure will need to move, and the need for support. Moving the structure can be problematic especially if the weather is unpredictable and violent.
The types of foundations available include lateral, longitudinal, and conventional. Each type has advantages and disadvantages. Lateral foundations use flexible steel posts and beams that enable the water to flow under various directions. They are most commonly used for large structures that cannot be moved. The main advantage they have is that they are very stable and require less maintenance. However, their disadvantage is that they are not suitable for smaller locales with less natural curvature.
The conventional system can be constructed for both residential and commercial use. The anchor system is built with two sets of vertical posts or vertical ties. There are a number of major benefits to this method including lower cost, less time frame for completion, and reliable installation. The system does not require any moving components which makes it ideal for a wide range of locales. A few minor disadvantages include the length of the piers and the distance between them could be significant depending on the chosen configuration.
For residential uses, concrete, stone, and composite materials are used for the vertical posts. The helical piers are then made from a combination of materials. Most foundations are placed directly onto the ground, but others may need to be supported on a foundation supported by soil, retaining walls, or other elements. Piers are capable of supporting themselves for long periods of time if they are anchored properly. The installation of foundations is best performed by a professional who has extensive experience in pier installation and the requirements of the local council.
Installing a pier is a major investment and should be considered carefully before commencing construction. The purpose of the project is to enhance the value of your property. If you are not experienced in the installation of these structures, you should seek the help of professionals who are trained in the field. The council will carry out a thorough inspection of your site before making a decision on the type of pier to be installed. The council will also offer advice on the most suitable pier to suit your needs and budget.
