Boring, also known as drilling, is a process of making a hole on the ground by excavating. Many years ago, this digging procedure left an ugly trench cut through the surface above. But this is not the case anymore. Precision drill technology now uses several trenchless techniques to make tunnels without disturbing the surfaces. This type of service is usually offered by specialised contractors for different purposes. For a residential setting, it could be to locate an underground water source or install an irrigation system.
Other intentions could also be any of the following:
Removing boulder from a property
Creating post or foundation holes
These top boring excavation services need heavy machinery and skilled operators for safety and precision of the work. In most cases, earth substrate and rocks have to be assessed first before proceeding to the actual drilling project. There are various techniques available for selection but the major factor that influences the choice is the ground condition.
Licensed tradesmen make sure that all the documents and requirements are ready before taking an action. It is critical to know what type of soil or rock there is to determine what particular method to utilise. Here are four common methods used to bore:
Auger. This is best for cohesive and other soft soils above the water table level. It could be done manually or using a mechanic. Manual augers can be used up to 6-metre depth while the mechanically operated can go for greater depths.
Wash. It is a simple way of making a hole in all kinds of land but cannot penetrate boulders or rocks. This is done by applying a pressure to force the liquid upward. Then the resulting samples can be analysed from the rate of progress and colour of the soil-water slurry.
Percussion. With this technique, any underground formation is broken by repeated blows of heavy chisel or bits suspended by cables or rods. This is suitable for advancing holes in all formations that are being disturbed due to the huge impact.
Rotary. Also called as core boring, this is a very fast method that requires no casing. A drill bit that is fixed to the lower end of the rod is rotated simultaneously by a chuck which is kept firmly in contact with the bottom of the hole. A drilling mud is used to bring upward the cuttings to the surface for a sample.
When looking for experts, the first thing to consider is to check out their reputation by getting references from previous clients. They are sure to share their experiences and give recommendations especially if the completed project is similar to what you wanted to take.
Next is to ensure that the specialist is truly and properly certified. This is vital for the job as it is mandated by Australian regulations. Lastly, opt for the company that has a flexible (with options to manage the bill better) and reasonable (excellent quality for an affordable price) payment scheme. There is a vast range of trusted and professional boring excavation contractors that deliver cost-effective and high-quality solutions for both residential and commercial purposes.
