Micropile foundations only began to be recognized as a more efficient and sustainable alternative to helical piles quite recently. Thanks to new technological advancements in machinery, it’s becoming a popular option.
Sometimes referred to as rock anchors, micropiles are a type of pile capable of acting as a support structure. This means, it transfers the load from the building to the soil or the ground. As its name imply, micropile is small in diameter, compared to its counterparts, which make it more effective in the drilling process and keying into rock. In situations where helical piles are not sustainable, as in due to several layers of rocks, micropiles come in. Like helical piles, micropiles offer the benefits of working well with tension and compression, speedy installation and little to no spoil generated during the process. Micropile Applications As previously mentioned, micropiles used to only be considered when helical piles are unsustainable. Sometimes, ground conditions warranted it because of considerations on time and cost. Micropile service is slow, but is a better choice for some because of its low vibration and noise quality. Should your construction project be located in an area with specific policies on noise control, micropiling is the way to go. Areas with little space to move around with also call for smarter micropile application. Other than having to comply to noise regulations and when drilling in congested areas, micropiles are ideal with shallow bed rocks, boulders and cavities, intermediate hard strata, and underpinning. Your engineer could help identify other situations in which micropiles make the job and the process easier and faster for you. Micropile Procedure The installation procedure for micropiles is similar with bored piling, which simply means it uses the drilling method. As a smart customer, it pays to know what your hired team of engineers is doing. There are four steps to the micropile installation. The first step is when they proceed to execute drilling and flushing. After this, they will have to perform withdrawing the drilling string and then insert the steel reinforcement and grouting. The micropile installation is done. It sounds technical, but it helps to pay attention to the service being done for you. Piling process is crucial, as it strengthens the soil on the ground so it is capable of supporting the stress and the load of the construction project. Making sure you get a quality micropiling service ensures your building stays erect and safe, no matter.

The Leaning Tower of Pisa is known worldwide for its unintended tilt. The building, or bell tower, as it was originally constructed for, began tilting during construction due to inadequate foundation and ground that was too soft to properly support the structure’s weight.
The tilt increased in the years that followed, and even before the structure was completed. It has been stabilised today, and while it attracts millions of tourists every day, a proper conduct of soil testing could have helped it become one of the most beautiful, and functioning, bell towers in Italy. The Value of Soil Testing Soil testing possibly could have already existed by the time the Tower of Pisa began construction, but it surely did not yet possess the rigour and science of the process known today. Nowadays, soil testing is the first step for any construction of building planning to understand and ensure the suitability of the soil for the proposed construction work. The soil profile of each location or site varies, and literally holds your building’s future; whether it will stay as erect and efficient, or lean and sink as time goes by. This refers to soil reactivity, which is the main point of soil testing. Reactivity refers to how much likely the soil is about to move, erode or expand. It also identifies how much the soil can support per unit area. Should the soil testing identify the area unstable, the construction work could be moved elsewhere or it could be better helped by a different kind of foundation. Naturally, difficult sites would cost more. Soil testing, as the first step before any proposed construction, definitely helps building owners and organisations cut costs. The Types of Soil Tests There are different type of soil testing one can conduct to ensure construction sustainability. Geotechnical engineers, or Geotechs, can help you identify which type of soil testing best fits your construction project. There are five basic types of soil tests you can conduct before building. The different types are moisture content test, Atterberg limits test, dry density of soil, specific gravity of soil, and compaction test. Other than these, there are also different types of soil test should you be doing a rebuild: one prior the demolition, and another before the rebuild. Some of these are conducted on-site, while some are brought inside a laboratory for thorough testing. The soil test process results will help the building or house owner manage a successful construction project. Knowing the soil profile of your house location before signing any building contract is compulsory, helps you manage the project successfully and even cut down costs. Consult with geotechnical engineers to determine your location’s soil type and bearing capacity before beginning the construction of your next project or home. |
