How to select an excavation method in Doncaster

February 26, 2021

Excavation is among the essential groundworks that are required when it comes to different types of constructions or mining. It requires one to have some unique skills and knowledge that are necessary for the excavation process. There are so many ways to decide to excavate your land, depending on the choice you make.

Most people will insist that they want a particular company in Doncaster to offer them excavation services, but they choose the excavation method they would like the company to use. These people do not know that there are different types of excavation methods, and each of the methods applies to different situations. Therefore, you have to ensure that you make your clients understand that they insist on a specific excavation form; you have to look out for several things before you make your final decision on the method to use. As a company, you have to ensure that you select the best excavation method in Doncaster depending on the following things.

Why and where the excavation is being carried out

One of the factors that will enable you to select the best excavation method is by determining why you want to excavate. For instance, people will hire you for the excavations services since they want to remove trees, prepare a garden, and even build foundations. Therefore, you have to ensure that you know why you are excavating to select the best excavation method. Whenever you are excavating to build foundations, you will not use the same excavation method when you are excavating to create a garden.

You need to ensure that you go up to the excavation site and look at the soil type in that site. The main reason is to ensure that you can determine the type of excavation method that will be perfect for the kind of soil present at the site. In case you find that the area has soft soil, you will be able to select the excavation method that will not affect the soil walls, causing crumbling.

It is also essential to consider this factor before you begin your excavation in Doncaster. Ensure that you select the right excavation method and the time and technique you should use when you are excavating; some of the factors to look for include the availability of existing buildings, vegetative cover, and drainage systems. These will help you to ensure that you select the best excavation method without putting them in danger.

The third thing on where to excavate is the groundwater conditions. Different grounds will have different states of groundwater. This is why there are grounds that have higher water tables than the others. When it comes to excavation, you will not use the same excavation method for the grounds with a high water table and a lower water table. Therefore, you have to ensure that you check on an area’s groundwater conditions before deciding on the method of excavation that is best for your case. 

The size of the project

This may seem like a less factor to consider when selecting the excavation method, but any excavation company needs to think about it. There are those projects that will require cumbersome equipment, while others will require straightforward equipment. However, it is very unprofessional to drag the heavy equipment to excavate a small project. It may help you finish the task very fast, but you will not have used the most economical excavation method.

For efficiently executed excavations, choose excavations performed by Hammer Excavations Melbourne.

What’s The SPT Test? How Does It Impact The Environment?

September 17, 2017

Rig workers at site take out drill core sample for geological logging, analysis and testing. Taking soil core sample. Made with shallow dof.

Are you familiar with the SPT test? If you’ve heard about this test, but don’t know very much about it, you’re going to want to learn more. This is a widely used soil testing method that is used in a number of fields.

The term, which stands for “Standard Penetration Test,” describes a type of test in which a sampler tube is driven into the ground. First, the tube is driven 150 mm into the soil. Once it reaches that point, the number of blows it takes for the sampler to reach 450 mm is measured.

The Pros Of The Test

There is a reason this test is so popular! It’s extremely easy to perform; only a small amount of equipment is needed. It’s also a very affordable test. The low cost has helped popularize this test.

This test is also fairly safe. While the soil itself can be damaged in the testing process, it is highly unlikely that the people doing the testing will be injured in any way.

The Cons Of The Test

While this is an excellent form of testing, it is imperfect. Since testing can cause damage to the soil, it’s not the kind of test that can be repeated. This means that the data that is gathered from the test is flawed.

The test shouldn’t be treated as foolproof. It should simply be used as a general guide. It can tell you more about the compactness of the soil, and it can also give you the chance to compare subsoil stratification.

Issues That Can Affect Your Results

Because the results of this test are imperfect, you will want to do everything that you can to increase the quality of your results. You should make sure that the borehole you use is completely clean, and you should make sure that you maintain the hydrostatic pressure of the borehole during the testing process.

You should closely monitor the test when it is going on. Make sure that there are no issues with the test. Even a single issue could negatively impact your data.

The Impact The SPT Test Has On The Environment

SPT testing can affect the environment in a negative way. While this testing isn’t as invasive as some other forms of testing are, it can still cause a lot of damage to certain types of soil.

Soft soil or soil that contains high amounts of clay can be liquefied during testing. If you want to minimize your impact on the environment, you should try to examine the soil before any testing begins. Look at the condition of the soil so that you can ensure you won’t have any issues during testing.

Now that you have a deeper understanding of the SPT test and the ways in which it impacts the environment, you can use the test in the best possible way. You can sidestep some of the issues that other people have encountered and ensure that your testing goes smoothly.
