Geotechnical Drilling Apopka How to Choose The Right Core Bit

No matter where or even what you are drilling, choosing the right geotechnical drill bit is one of the most important decisions for the job ahead. It can have an great impact on the speediness and success for the project involving geotechnical drilling. Apopka residents should know that geotechnical drill bits are made with a different combination of metals and alloys. They have different levels of impregnation of diamonds and different configurations to create different compositions to break through different sediments and rocks. One thing that affects a company’s choice for a drill bit is the type of ground you are dealing with.

Ground Hardness and Variability

One of the tricks that help a geotechnical drilling company choose the correct drilling bit is by following a chart known as the Moh’s Hardness Scale. The scale consists of a numbered system that represents the relative hardness of various minerals. When working with geotechnical drilling, Apopka drillers follow the scale so that they can pick a drill bit suitable to the hardness of the ground that is being drilled. Some ground is more variable however. It can be soft towards the surface and slowly becomes harder the more you dig down. When dealing with variable ground there are many products on the market that provide the versatility needed to perform well in varying conditions

Terrain and Type of Drilling Rig

Terrain can be either fractured or competent and each will need a different kind of drill bit to dig through. For example, a bit with a deep lateral discharge is ideal for fractured rock as it designed with angled waterways for greater removal of drilling fluids. The type of drilling rig and the capacity at which it is working are both considering factors of what drill bits you can use. When performing Geotechnical drilling, Apopka residents should realize that not all drill bits are compatible or appropriate with all kinds of machinery such as a drilling rig.

Geotechnical Drilling Casselberry How Fractured Ground Affects Drilling

When it comes to drilling, it is not so cut and dry and you might think when boring thru the Earth. The kind of ground conditions a driller encounters will play a huge role in how the project goes and the types of decisions that will need to made by a company performing geotechnical drilling. Casselberry residents need to understand that ground conditions include more than just the hardness of the ground and choosing the right matrix for a particular hardness. While it is important, other decisions will need to be made as well. Fractured ground is common for drilling companies and they should consider the following before committing to a drilling endeavor.

Fractured Ground Has The Potential For Water Loss

Ground that has a fault or void present can cause poor water circulation or loss of water return leading to poor drilling bit performance. The returning flow of water from the bore has a cushioning effect on the drill rods, making it easier and more effective to continue geotechnical drilling. Casselberry drillers can encounter fractured ground at some point in their project, which causes the driller to lose return water. This means that the upper part of the drill string may not experience this cushioning effect and vibration may be increased at that point, making it hard to control and hard to go deeper with drilling.

Hitting a Void

When drilling in highly fractured or broken ground, drilling companies run a higher risk of hitting a void or large fracture and having your drill water escape through that fault. Drill operators find out themselves that a dry hole and dry bores are a pain to deal with. They end up drilling blind because they are not getting any water return and they will not get an indication that the core is blocking. In this circumstance of geotechnical drilling, Casselberry drill operators will have no water return, which greatly increases the drilling cycle time and, if they are in an area with limited water resources,they will not be able to recycle your water.

Geotechnical Drilling Clermont What to Know about Dull Drill Bits

The more you use a drill bit, the duller it gets, making it hard to drill through hard layers of sediment and rock. Unfortunately, there is no end all be all way or even an easy way for sharpening a bit that has been worn down due to geotechnical drilling. Clemont drillers often debate back and forth as to what causes a drill bit to go dull, how to prevent it in the future, and also how to fix a drill bit if it happens to be performing at a sub par level. For example, Diamond impregnated drill bits are made to be self sharpening, but after a while the drill bit can become polished, making it unable to cut through anything.

What causes Dull Drill Bits in The First Place?

There is no one reason why a drill bit becomes dull after a while of use. For Example, The drilling parameters or settings that you have chosen do not suit the ground conditions. This could mean that you have chosen the wrong drill bit for the job, or that below the surface is a different type of material that you were not prepared for. Core bits are developed for particular hardness and level of abrasiveness and are not suitable for every job in geotechnical drilling. Clermont drill operators should know that if the ground is variable, you will have to switch drill bits at a certain length to prevent dulling the initial drill bit.

What Can You Do With a Dull Drill Bit?

Once a drill bit becomes dull, it will have to be sharpened in order to get it to drill properly. With the example of a diamond geotechnical drilling bit, Clermont drillers will have to remove a thin layer of the matrix in order to expose those diamonds so that the bit can start cutting again. Sharpening a core bit can be a little tricky so if you are uncertain as to how to perform the procedure, find someone who has experience in sharpening dull bits. Performing sharpening improperly can result in wasting a lot of your matrix.

Geotechnical Drilling Kissimmee Geotechnical Boring VS CPT Sampling

There are a wide range of reasons why soil needs to be tested. For some applications, it is important to get data about soil that is sub-surface, and in many cases getting data from deep under a site can be useful or essential. When most people imagine how you would gather data from soil that is deep underground, they imagine some big drill performing geotechnical drilling. Kissimmee Residents should know there are special kinds of boring tools that will let you drill deep into the ground and extract a sample of the soil at almost any reasonable depth for analysis.

Understanding Subsurface Geology With Boring

whether it be small-diameter or large-diameter equipment, geotechnical boring allows users to see the solid that is extracted from the ground. This can be useful for gaining an understanding of the sub-surface topology if the goal is to create a multi-dimensional map of the subsurface Geological conditions. With Geotechnical drilling, Kissimmee residents can have the samples of the boring tested in a lab setting to understand the composition of the soil in order to better understand what the subsurface underground looks like. The main advantage that soil sampling with boring is you can actually see a sample from under the ground.

The Advantages of Using CPT to Sample

CPT or Cone Penetration Tests measure the physical properties of the subsurface soil directly, without removal. This provides the advantages of generating a more accurate reflection of conditions underground as well as avoiding the necessity of sending samples out for lab testing.
If you need to sample your property with geotechnical drilling, Kissimmee residents should consider the faster cone penetration in order to save you time. Faster time is also a little bit more expensive though. Also, there are instances where direct sampling is still your best option to see what lies below the surface.

Geotechnical Drilling Ocoee Things to Consider for Improved Core Recovery

One of the key parts of geotechnical drilling is obtaining soil and sediment samples from a location and having it analyzed in a lab setting for a multitude of different reasonings. Core recovery, and how to improve it, is a topic that comes up often in a discussion between many field technicians. This is not surprising, since it is the purpose of every driller and drilling company to want to be efficient and cost effective when performing geotechnical drilling. Ocoee drillers should consider these factors among many others to improve core recovery.

Start With Choosing The Right Drill Bit

Knowing how to choose the right core bit for the type of ground you will be drilling in will go a long way in helping your core recovery. Factors related to ground that you should consider include a rock’s hardness, whether ground is competent or fractured, variability and also abrasiveness are important. In addition, variables such as companies type of drill rig, level of experience, depth of drilling expected and knowledge of the area will all factor into your choice for geotechnical drilling. Ocoee drilling operators should also consider adding fluid additives to help make it easier to retrieve a core sample. For example, if you find yourself drilling in sandy or gravel conditions, an additive can be used to solidify non-stable and abrasive grounds.

Do Not Neglect Regular Maintenance

Once you have chosen the correct drill bit, remember that you should always be drilling with clean and lubricated equipment. Drilling companies’ inner tube should be cleaned thoroughly every time the core is removed, and they should properly rinse both the inside and the outside of the inner tube, core case and spring. With Geotechnical Drilling, Ocoee drillers should know that Clean tubes accept core easier and descend faster. Make sure to use a good extreme pressure or multi -purpose grease to pump into the bearing assembly

Geotechnical Drilling Oviedo Thread Compounds and Lubricants for Drill Rods

Depending on the task at hand, one of the more common tools that a geotechnical drilling company has to deal with are drill rods. Drill rods are a hugely important part of drilling equipment, and taking care of them can have a major impact on a company’s drilling performance. The regular use of drilling lubricants and thread compounds are important for prevent breaking and maintaining a healthy drill string and helps avoid many other problems related to geotechnical drilling. Oviedo drillers should know these reasoned for using thread compounds and lubricants.

Help Prevent Rods From Cracking and Leaking

A good quality thread compound will help protect the metal surfaces of the threads and provide a good seal to prevent leaks in drill rods. Little or no lubrication of the drill rods can cause more vibration and increased torque which in turn increases wear and tear of the rods. Drill rod threads that are worn, cracked or otherwise damaged prematurely will eventually leak during projects involving geotechnical drilling. Oviedo drillers should also be cautious of excessive vibrations because it can cause drill rods to crack. Rod grease can help reduce vibration and extend the longevity of your drill string.

Stop Rods From Bellowing and Prevent Rust and Corrosion

Because rods are metal, they are prone to oxidation and affected by rust. High quality lubricants are highly water repellant so they are resistant to water washout. When applied properly, the lubricant will adhere and protect the rods, helping to keep the rods and bits lubricated and extend the life of all metal parts. Another popular problem with geotechnical drilling, Oviedo drillers should used lubricants and thread compounds to prevent belling. What causes the the rod to bell out can be torqueing, over tightening, and excessive vibration for lack of lubrication. When working with drilling rods, it pays to shell out a little extra cash to make sure all your tools and equipment is in optimal condition to be used on a project.

Geotechnical Drilling Saint Cloud The Advantages of Cone Penetration Testing (CPT)

Cone Penetration Testing is starting to gain rapid accepting among the engineering community because it addresses many of the disadvantages of typical boring technique of geotechnical drilling. Saint Cloud Residents do not have to wait for samples to be sent to a lab to identify what is the composition of the subsurface sediment. There is no wasted time, energy and resources digging holes, just to get a sample of what’s way down deep. CPT gives you the data that you need as you are getting to the depth you want data on.

Cone Penetration Testing Is Much Faster Than Boring Testing

CPT is an In Situ test, providing advantages that are especially beneficial if you do not have the time or expenses associated with sending samples off to a lab. Samples can not get disorganized or lost because CPT uses a data-logger to ensure that all of the root data taken is recorded and logged in a well-organized format. Engineers can gather data in real-time, and as a result move along much faster, which in return can provide immense savings to the overall project costs on both parties ends. With geotechnical drilling, Saint Cloud residents can pay a lot in time and money with traditional boring.

Cone Penetration Testing is Much More Accurate Than Boring Testing

Although Geotechnical Boring may seem as though it is a sufficient option for site subsurface investigation, geotechnical boring doesn’t provide the accuracy and efficiency that Cone Penetration Testing can offer. Geotechnical Boring has the advantage that it uses many of the skills of conventional well drilling. Because the Boring operations and technical analysis, such as laboratory tests, are separate, Geotechnical Boring can require less skilled operators on site than CPT. However, a price is paid in efficiency as often the site samples are sent to a separate lab for testing samples from geotechnical drilling. Saint Cloud residents and landowners should consider CPT for their next geotechnical survey and sampling.

Geotechnical Drilling Sanford Benefits of Testing Your Property

Geotechnical drilling companies do not just drill for the sake of making a deep hole in the ground. Many companies that drill are often taking samples of different areas of a property to get a full assessment what is going on below the surface. Farmers for example are one of the groups that can benefit the most for site drilling and sampling. With Geotechnical Drilling, Sanford residents can have many aspects of their property tested such as with soil testing and water testing. Geotechnical companies are called out to a residence to dig the samples, and then they send the samples out to laboratories to have them analyzed to see what exactly you are dealing with and what is going on below the surface.

The most Popular Medium to Sample: Soil!

It comes as no surprise that most of the sample drilling that geotechnical companies have to dig for is actually soil samples and soil composition tests. By getting a piece of their property sampled, farmers can increase their productivity by identifying their soils nutrients and chemical compositions that are limiting plant growth in their crops. With geotechnical drilling, Sanford farmers and residents can find out the composition of their soil to know how efficiently their fertilizer is working and if they are using to much or too little for specific crops and locations. Last, soil samples can help identify pollutants and contaminants on your property.

Benefits of Water Testing a Site

Usually when geotechnical drilling companies get involved in a water project, it is usually to dig holes for a structure such as a bridge or dock. It is possible to sample the soil composition underneath the water as well as sample the water itself to see if there is anything suspicious. When testing water through a company that specializes in geotechnical drilling, Sanford residents can find out if there are any foreign contaminants in their water that can cause health problems for people, livestock, and crops alike. Contamination and pollutants are a huge concern for any water source, especially one that supplies many.

Geotechnical Drilling Winter Garden Traditional Sinkhole Repair Methods

In the state of Florida, sinkholes are a very common problem that may need to be addressed at some point in your homes existence. Repair methods can vary, and the method used depends largely on economics and the location of the sinkhole. The method and materials needed to fill in a small sinkhole in a backyard or in a rural area can be quite different from those needed to repair a sinkhole in the middle of a street or under an occupied home or business in a highly urbanized area. Sinkholes require some geotechnical drilling; Winter Garden residents should not be alarmed by a drill making the sinkhole bigger. Drills are needed in order to fill the sinkhole.

Sourcing a Sinkhole’s Triggering Mechanism

During repair, a sinkhole’s triggering mechanism must be addressed in order to minimize additional soil settlement or sinking. As water is usually the primary triggering mechanism, it is necessary to identify and remove to the extent the possible source of the water that may have caused the sinkhole. It is better to construct a plug, or a drain stopper, directly at the location of the bedrock drain. This allows the plug to be in direct contact with the bedrock, providing a better seal. This is an easy task for a team that in knowledgeable in geotechnical drilling. Winter Garden should know that there are other methods for filling sinkholes as well.

Permeation Grouting is Sometime More Appropriate

Permeation methods are effectively used to fill voids, cracks, fractures, cavities, and to create barriers to the movement of liquids through the ground. Permeation grouting is the direct pressure injection of a fluid grout that is either chemical or cementitious into the ground to fill the spaces between particles. Pressure grout methods are used for preventing water flow, stabilizing granular material, encapsulating organic material, and improving the physical properties of soil or rock with geotechnical drilling. Winter Gardens residents should know that the process is quite flexible, and therefore, is advantageous for use in urban areas or areas of limited access.

Geotechnical Drilling Winter Springs Handling Rock Abrasiveness

Drilling companies deal with a lot of  conditions that are not ideal for their team or their equipment. Of the many ground conditions that they may have to deal with, rock abrasiveness is probably one of the most common problems with geotechnical drilling. Winter Springs drill operators that have to deal with abrasiveness usually means that it is going to be difficult to drill through any level of ground hardness because abrasive ground can wear down drill bits prematurely. It does not matter what drill bit you use because abrasiveness is a factor that is going to destroy your drill bit no matter what.

Consider Using Core Bits Designed For Abrasive Rock

One of the most important aspects of drilling is making sure that you have the right drill bit to bore through the sediment or rock in your path. In a case in which you are dealing with abrasive rock, do not use one of your usual drill bits. Instead, companies produce drill bits specifically designed for the abrasive rocks that show up in geotechnical drilling. Winter Springs drill operators should be aware that these kinds of customized bits have a special matrix made of alloys and diamond designed to penetrate abrasive material well and last longer than traditional drill bits would.

Adding Drilling Fluid Can Make a World of a Difference

Drilling fluid additives, such as some polymers, are products that can improve the performance of drills in abrasive conditions of geotechnical drilling. Winter Springs drill operators should be aware that drilling fluid can ensure that your drill mud has the necessary viscosity to carry and flush rock cuttings from the bore and keep them from settling at the bottom of the hole you are drilling. Drilling fluid not only makes it easier on your drill by flushing and cooling the moving parts, but it can also help in situations that have rock abrasiveness.
