Piling Pipe is used transfer the loads of structures from shallow, weak soils unable to support such a heavy foundation to stronger layers that are found deeper underground. Pipe piling is driven into the ground either open ended or closed ended. If it is open ended, soil is able to enter the tube or it is filled with concrete to provide additional support or capacity to the structural foundation. There are several materials available that are used to manufacture piling pipe including: Steel, timber and concrete.
Steel
Steel is a popular choice for pipe piling application because of the many advantages it provides to consumers. One main advantage is that steel pipe piling come in a wide variety of sizes while pipe piling made of material like timber which is usually manufacture in shorter lengths. Steel is a widely-used choice because of its sustainability in hard-driving projects, and it is also easier to drive than other materials – especially through harder soils. Another benefits includes a minor displacement of the soil when steel in the chosen material.
Timber
Timber piles are constructed of wood, and due to the material wide availability piles made of timber are usually not as expensive as other material like steel or concrete. While the cost of timber piles is definitely an advantage to those utilizing the product, some timber piles – depending on the type of wood used and the source – may not be the most suitable choice for heavier loads. Other advantages to choosing timber include that it is easy to handle and made of wood – a material that doesn’t corrode. Also, in most cases timber pipe piling is resistant to decayed if it is fully driven into the ground but it may require treatment beforehand to prevent damage from decay and insects, which can be a disadvantage to some. Another disadvantage is timber piles are more likely to be damaged during driving.
Concrete
Lastly, concrete pipe piling is another available choice. Some positive aspects of choosing concrete are that it is relatively inexpensive and resistant to corrosion – unless utilized in marine applications. It is also a good choice because the length of concrete pipe piling can be easily adjusted to match customers’ specifications and it as a low level of noise as it is driven into the ground. However, on the flip side concrete does have some disadvantages to the consumer. It is hard to handle and transport, and splicing concrete can be a real problem.
