Bored Piling is a type of reinforced-concrete foundation that supports structures with heavy vertical loads. A bored pile is a cast-in-place concrete pile that is cast on the construction site. This differs from other concrete pile foundations, and concrete square pile foundations, which use precast concrete piles. Installing a bore pile starts with drilling a vertical hole into the soil, using a bored piling machine. The machine can be outfitted with specially designed drilling tools, buckets, and grabs to remove the soil and rock. Screw piles can be drilled to a depth of up to sixty metres and a diameter of 2.4 meters. When used for foundations, bored piles are specified for building and other structures that impose loads in the thousands of tons. In addition to foundation systems, bored piles are also used to create structural underground walls for earth retention.
There are many advantages of bored piles or drilled shafts over conventional footings. Bored piling allows the piles of variable lengths to be extended through soft, compressible, or swelling soils into a suitable bearing material. Bored piles can also be extended to depths below frost penetration and seasonal moisture variation. By using bored piles, large excavations and subsequent backfill are minimised and there is less disruption to the adjacent soil. Bored piles reduce the disturbance of adjacent piles or structures. For many design situations, bored piles offer higher capacities with potentially better economics than driven piles. Bored piles drilled into rock conditions enhance the chances of minimising any foundation settlement. Bored piles are commonly used as a foundation solution when the conditions of the ground are considered fair to good, that is there is no threat of shallow water table, soils are cohesive, or rock and spoil removal is not a problematic or costly trait. Bored piles are often an effective solution to piling where various load cases are applied to pile such as tension, uplift, or large piles loads required.
When building a large structure, you need to have an incredibly solid foundation. That’s what piling is for. By setting up a deep foundation, piling contractors make it possible to build everything from a supermarket to apartment complexes and even office towers. This is a highly specialised trade, and it would be impossible for a non-specialist to know precisely where to turn. Given the level of specialisation involved with laying the deep foundation, experience is a critical consideration. You should look around for piling contractors that have the track record to back up their claims. When choosing a piling contractor, it is important to know what type of foundation you will need. Deep foundations are necessary when the ground and soil conditions are pool and the building that is to be constructed is going to have more than one story. If you already have a building then, mini piling is the solution. Hence it is very important to educate yourself and learn the basics so when the piling contractor is on-site, you can ask the right questions and understand the situation better. It’s essential that the companies have the access to the tools needed for the job. The cost of the project should never be the deciding factor but it’s certainly a significant component to consider. Saving money now could mean a higher cost in the future when the foundation must repair due to being cheaply constructed. Hence, you should find a piling contractor which fits your budget and can also give a breakdown of the price so you know exactly what each step of the process will cost.
