How Blast Hole Drilling Works

Clay soils tend to shrink when the climate is dry and expand when it is humid: normally, the lower the shrinkage limit and the wider the range of variation of the plasticity index, the more there is a change in volume and the greater the extent of this change. These variations in volume can be caused by the drying of the soil after the construction of the structure or due to a loss of natural humidity following the heating of the buildings.

Variations in volume, again, can be generated by drying the soil produced by vegetation (trees or shrubs around the structures for aesthetic reasons). Finally, variations in volume can also occur as a result of an artificial increase in soil moisture below the structure (buildings for cold storage subject to thermal gradient and without adequate insulation). In any case, before starting the calculation procedures of a foundation project, it is also necessary to analyze the meteorological characteristics of the site.

Droughts tend to dry the soil; after which the rains cause significant swelling. Since there is not enough rainfall to wash away and alter the clay minerals responsible for the volume variations, the same remain unchanged near the surface of the soil and quickly become wet during rainy periods.

In these regions the land is particularly complex for construction because the water vapor, migrating from the water table (sometimes distant from the ground level) condenses on the lower sides of the slabs and foundations that require Blast Hole Drilling.

The ground below the inner areas of the buildings can, finally, become saturated due to the effect of condensation coming to swellings unless the construction is not heavy enough to counteract the (high) reaction pressure. A further difficulty arises from the fact that in arid climates the soil around the perimeter of the buildings remains in a much drier state than that of inland areas, so there are significant differential movements.

In terms of relative values, low volume variations can be assumed to be those with values ≤ 5 while they can be interpreted as very large when> 25. The structures whose foundations are placed on expansible (or expansive) land require special construction techniques for Blast Hole Drilling that is used for foundations.

Creating foundations near an existing structure the line joining the base of the new foundation with the base of the existing foundation must form an angle ≤ 45 ° with the horizontal plane. From this it follows that the distance m must be greater than the vertical distance between the two foundations; the approximation produces very strong pressures in favor of safety in the area where more than one foundation contributes to these pressures.

Reasons Your Construction Company Should Outsource A Drilling Company

People in the construction industry sometimes require drilling the ground so that they can proceed with a project. Unfortunately, sometimes your current team does not have the drilling experience necessary. Consequently, you might have to hire a drilling company to avoid entering a potentially dangerous situation when you let the inexperienced team drill the ground. It is paramount to hire a drilling company in Perth for the best results and keep your project on track.

You will be done faster

Most construction companies complete their projects within the stipulated time. However, the chances are that your project will lag if you have to stop and train your team so that they can drill adequately. As such, you should hire a drilling company to assist with the drilling so that you do not lag behind the time agreed upon with your client.

Drilling companies have all the necessary tools

Since you are not an expert in drilling, you might not have the essential drilling equipment, or you have a few pieces. On the contrary, a drilling company has an array of the latest drilling tools and technology to perform the task professionally. You can confidently hire a professional drilling company even if the drilling task is complex.

Keep your employees safe

Studies reveal that the primary cause of work injury cases is the misuse of equipment. Your team will be at risk when they operate the drilling equipment without the knowledge to do so. And, the construction company has a responsibility of protecting its employees. You might be forced to buy expensive safety equipment though it does not guarantee that employees will not make mistakes. Professional drilling firms have the tools, training and safety equipment to go through the task safely. Also, the drilling company in Perth takes responsibility for anyone who gets injured on the assignment.

Maintain structural integrity

You should also put into consideration the safety of people who will live in the building once it is completed. Professional drilling companies can assess the structural integrity of a structure before they even start drilling. They identify concerns during the drilling process then resolves the concerns before completing the task to avoid putting residents at risk. Hiring a drilling firm also prevents future damages, which are costly. Also, you do not want to be sued for damages if the building experienced significant issues because the drilling destabilized the area.

With these benefits in mind, you can now see the importance of a professional driller. A professional drilling firm to protect your construction firm from a future lawsuit. However, you must select a licensed and experienced driller.
