Sinkhole Investigations Tampa What Data Can You Obtain from Sinkhole Investigations?

Tampa and the entire state of Florida is home to some unique conditions; conditions that are very friendly to sinkhole formation. In fact, Florida is one of the most sinkhole prone regions on the planet due to our unique geology.

So, what causes sinkholes and how can companies such as Amdrill, Inc. help with sinkhole investigations? Tampa natives can read on to learn more!

Why is Florida So Prone to Sinkhole Formation?

The state of Florida has some unique geology that makes this peninsula prone to sinkhole formation. While many other regions of the country are situated atop a dense type of bedrock, such as granite, Florida is located atop limestone bedrock. Overlaying this limestone bedrock is very sandy soil, which can hold a lot of water and it is also highly permeable when it comes to underground water flow.

Unfortunately, limestone is prone to dissolving when it’s exposed to even mild acids, including the acid that’s found in acid rain and even in groundwater. This can result in the erosion of the limestone, which dissolves over the years to form a large underground void or air cavity. Think of it as a “bubble” in the earth. The weight of the overlaying rock and soil can ultimately cause the void to collapse, resulting in the formation of a sinkhole.

Of course, Florida also sees lots of rain, which means there’s more groundwater, a faster rate of limestone erosion and there’s also a potential for greater pressures and added weight in the land that overlays these underground voids. This can have added weight can prove to be too much, causing the earth to collapse as a sinkhole forms.

How Do You Perform Sinkhole Investigations?

Tampa natives routinely call Amdrill, Inc. for help with sinkhole investigations. An investigation may be initiated after a property owner notices changes in the terrain, such as rapidly-forming depressions or other shifts in the earth. The signs of an impending sinkhole formation are most obvious when you have a solid structure, particularly one made of inflexible materials such as masonry, cement and concrete. While wood structures have a small amount of give, these inflexible materials tend to crack and shift in response to the ground movement. So, it’s not uncommon to see cracks and other signs of damage in an area of a structure.

When a sinkhole is suspected, the property owner will typically call a sinkhole remediation and investigation team. The efforts may include the use of ground-penetrating radar, which evaluates the earth’s density, identifying the location of underground voids. Our geotechnical drilling teams can also come in to perform drilling operations, as it’s very apparent to the drill operator when the drill bit strikes an underground void because there is a sudden lack of resistance and friction.

Drilling can be used to can determine the exact depth and dimensions of the underground void. The bore holes can also be used as access points for pumping a filler material into the void, such as concrete. Once filled, the hole will no longer be prone to collapse. In cases where the void is extremely large, any overlaying structures may be reinforced with stabilization rods that can be penetrated down into the bedrock (with the help of our drilling teams.) This way, the structure will remain standing, even if the surrounding ground falls away.

Precision Drilling Tampa What are the Most Common Uses for Precision Drilling?

Tampa geotechnical drilling firms such as Amdrill, Inc. are frequently called in to perform precision drilling projects. Precision drilling methods may be required for a number of different projects, from projects involving an existing well, too difficult access drilling projects and sinkhole investigations, amongst other efforts.

So, in today’s article, we’ll explore precisely what’s involved with this specific style of drilling and some of the special considerations that our technicians must keep in mind when embarking upon this type of project.

What is Precision Drilling?

Tampa drilling technicians may be called upon to perform precision drilling techniques in a variety of different settings and scenarios.

Perhaps one of the best-known uses of precision drilling occurred during the Deepwater Horizon oil rig disaster in the Gulf of Mexico, as BP drilling technicians were tasked with drilling relief wells through thousands of feet of bedrock to hit the primary well, which was just a matter of 30 inches in diameter. They were drilling in an environment with 5,000 feet of water and the intersection point was 2.5 miles beneath the sea floor. This remarkable feat of precision drilling ultimately brought an end to the Deepwater Horizon disaster, as experts were finally able to cap the well once those relief wells were drilled.

Of course, this is an extreme example of precision drilling, but there are many other projects that may involve a high degree of skill and expertise.

One of the most common uses for precision drilling involves difficult access drilling projects, where there may be limited access to the area that needs to be sampled, drilled into or otherwise accessed.  In these settings, our drilling technicians may need to drill in a very precise angle and direction in order to hit the target.

Cases where you’re working with an existing underground structure, such as drilling with an objective of intersecting existing well, aquifer, pipeline or bore hole, also require a unique degree of precision. The task can be made even more complex if you must maneuver around structures or obstacles.

Even a case involving sinkhole investigation and remediation can require precision drilling techniques, as you must place the drilling rig on stable ground; ideally ground that is not situated directly atop the void if the vibrations and added weight trigger a collapse. But the presence of structures such as buildings and roadways can make this more challenging, resulting in some cases where you must position your drilling rig a bit further away than would be considered ideal. This can make it more challenging to hit the target.

When it comes to precision drilling, Tampa natives trust Amdrill, Inc. because we have the equipment, training, vehicles and expertise required to get the job done properly.

Marine Drilling Tampa What Are the Uses for and Challenges of Marine Drilling?

Tampa developers, environmental experts or companies involved in extracting natural resources such as oil and natural gas, may turn to a geotechnical drilling firm like Amdrill, Inc. for help, as one of our many specialties is marine drilling. Tampa Bay marine drilling projects may entail several different challenges so for this reason, it’s important to have an experienced team of technicians overseeing the drilling efforts.

What is Marine Drilling?

Tampa natives may turn to an environmental drilling firm like Amdrill Inc. for help with a marine drilling project, which is the term for any drilling project that involves a marine environment, whether it’s an ocean, a bay, a river, a lake, a pond or wetlands.

Marine drilling can be utilized for several different projects, including:

  • Determining the composition and integrity of the seabed
  • Sampling the sediment and the bedrock that lies beneath
  • Evaluating the environment for the presence and prevalence of contaminants
  • Drilling wells for gas companies, oil companies or energy companies
  • Drilling bore holes and monitoring wells
  • Evaluating the depth and extent of water saturation in a location
  • Evaluating the depth and integrity of the bedrock
  • Drilling holes for anchors for a larger structure such as a wind turbine, dock, bridge or another construction project.

These are just some of the many Tampa marine drilling projects that Amdrill, Inc. has performed. Of course, marine drilling is associated with lots of challenges. One challenge involves the very act of drilling underwater or in a wetlands environment. This requires the usage of a boat, barge or amphibious vehicle. Wetlands and shallows can be quite challenging in cases when you require a large, heavy drill for the project, as large drills require a large boat, barge or amphibious vehicle, but this can create challenges since you risk “bottoming out” and experiencing other challenges maneuvering the appropriate equipment into position.

Wetlands and marine environments also feature delicate ecosystems; many wetlands are even considered “protected” environments.  So, it’s important that you work with a company that can take measures to prevent and limit any damage to the surrounding environment. This can create some additional obstacles in a marine drilling project. In areas, adjacent to a marine or wetlands environment, your drilling team will need to ensure that lubricants, drill cuttings and vehicles do not cause any damage.

Accessibility and environmental concerns aside, you also have challenges associated with the dynamic nature of a water environment, with changing tides and water depths, which can complicate the drilling project. Simply keeping the drilling rig in a stationary position can be tremendously challenging amidst the waves and tides. So, you need a company that has the right vehicles and the right technicians who know how to ensure that the drilling effort goes as planned. We have also encountered issues when drilling at depths, as the pressures found in deep water environments can have some unique impacts on the drilling equipment.

For these reasons, it’s vital to trust your project to an experienced Tampa marine drilling company like Amdrill, Inc.

Geotechnical Survey Tampa How is Drilling Used in a Geotechnical Survey?

Tampa geotechnical drilling firms such as Amdrill, Inc. are routinely called in to perform drilling as part of a geotechnical survey. But what is a geotechnical survey and why is drilling used as part of the surveying process? Well, that’s precisely what we’ll explore in today’s article.

What is a Geotechnical Survey?

Tampa technicians with Amdrill, Inc. may be dispatched to drill at a site that’s the subject of a geotechnical survey. This type of survey is typically performed as one of the first steps in evaluating a site’s suitability for the construction of a structure. This can include a house, a commercial or industrial structure, a large multi-unit building, or another structure type, like a bridge, levee or communications tower.

When performing a geotechnical survey, Tampa surveyors will typically be seeking a lot of data and information, including:

  • The soil composition
  • The soil density
  • The soil saturation levels
  • The moisture level in the soil
  • The groundwater levels
  • The depth and integrity of the underlying bedrock
  • The presence of any underground voids which could collapse into a sinkhole

These attributes can be determined through geotechnical drilling efforts, which can include everything from performing permeability drilling tests, to collecting soil samples and core samples – cylindrical tubes of earth that are vertically extracted to provide insight into the composition, moisture content, compaction levels and density. Core samples are effective at providing experts with key data that may otherwise be lost during the drilling process, which can disrupt the earth, making it challenging to accurately evaluate the attributes of various soil layers.

In other cases, if a geotechnical survey were to reveal the presence of underground voids which could potentially collapse to form a sinkhole, the developers may choose to drill into the cavities. Then, concrete can be pumped into the void, filling the cavity and preventing a future collapse. This is one of the many options available for sinkhole prevention.

Geotechnical Services Tampa How Do Engineers and Developers Use Geotechnical Services?

Tampa geotechnical drilling firms such as Amdrill, Inc. frequently perform geotechnical services, which can include drilling efforts which are an important aspect of the surveying process. The integrity of the soil and underlying bedrock at a site will have a major impact on the overall stability of the site. Other wildcards, such as highly saturated soil, a high-water table or underground voids, can complicate matters significantly, resulting in the potential for serious instability or even a catastrophic collapse.

Several different clients utilize our geotechnical services. Tampa engineers, including civil engineers, along with developers, property owners and other companies (particularly companies in the energy sector) call upon our expert technicians to provide geotechnical drilling services in a wide range of environments, including on land, in remote forested locations, in wetlands and in marine or ocean environments.

What Are the Uses for Geotechnical Services?

Tampa drilling technicians with Amdrill, Inc. provide geotechnical services that span a number of different areas. Some of the clients who contract our firm include the following.

Civil engineers – call upon our drilling technicians to help gather key data from a site so they can solve an engineering challenge, whether it’s with a canal, levee, bridge, roadway or drainage system.

Construction and building engineers – who are designing large commercial and industrial buildings, multi-unit office or residential structures, bridges, canals, communications towers, wind turbines, or other structures, particularly those that are especially large, tall, heavy or otherwise unique. We can gather data from the soil and bedrock that allows experts to evaluate the suitability of a site.

Construction firms and developers – who need help installing stabilization rods into the bedrock to create a “deep foundation” or to stabilize an unstable structure. We can also assist with extracting samples from the foundation if it’s suspected that defective or otherwise problematic building materials are present.

Sinkhole investigation and sinkhole remediation companies – that require help accessing an underground void that they wish to fill with cement to prevent a collapse. Some remediation efforts may also involve penetrating down into the underlying bedrock and inserting stabilization rods to help support a structure that’s overlaying the potential sinkhole site.

Environmental firms – that require help evaluating a site for the presence, nature or extent of contamination. This can include evaluating for the depth of contamination, the precise location of the contamination, and whether the contaminants have reached underground aquifers, wells or other water supplies.

Notably, Amdrill, Inc. has lots of different drilling rigs, which can be placed on a variety of different vehicles, including boats, barges, trucks, ATVs, remote controlled vehicles and even vehicles with tank-like tracks, which are ideal for rugged, hard-to-access areas. So, there is virtually no area that’s inaccessible to our Tampa geotechnical service providers.

Geotech Environmental Tampa How Can Projects Benefit from Experts in Geotech Environmental?

Tampa geotechnical drilling firms such as Amdrill, Inc. deal in a range of geotech environmental projects, such as performing drilling operations that aid in geological investigations, investigations into the presence or extent of contamination in soil, groundwater and a variety of other areas.

Contamination is one of the most significant issues impacting our environment and drilling can be a key method for determining and evaluating the extent and severity of contaminants. We also work with environmental experts who require help extracting ground and soil samples, which can then be used for   evaluating the earth, including the degree of saturation and various geological attributes.

These are just some of the many Geotech/environmental drilling projects that we perform in Tampa and the surrounding region.

What are the Most Common Drilling Projects Involving Geotech/Environmental?

Tampa technicians with Amdrill, Inc. are frequently dispatched to assist with geotechnical and environmental drilling projects.

Environmental drilling projects very frequently involve investigations concerning contamination. Contamination can arise from many different sources and the environmental and ecological impact can be quite dramatic. For this reason, we find great satisfaction in aiding with these investigations. Our drilling technicians can help environmental scientists acquire key data for analysis, including:

  • The precise nature and severity of the contamination
  • The depth of soil affected by contamination
  • Whether the contamination has extended down into the groundwater supply and/or aquifers
  • The extent and location of the contamination
  • Groundwater content and water table levels
  • Sediment composition and contamination level
  • The soil composition and presence/nature of the microbial life
  • Soil saturation levels and beyond

In addition, we can also provide geotechnical drilling services, which may be considered alongside environmental factors when building a structure of some type, whether it’s a new building, a canal, a bridge or a levee. Whatever the case, we can help you to derive important data about the composition, integrity and other properties of the soil and underlying bedrock.

When performing Geotech environmental Tampa drilling crews are often asked to insert a monitoring well or other monitoring equipment which can be used to keep an eye on the site and collect data over an extended period. Environmental scientists can glean a lot of insight from noting changes that occur over time, so these monitoring wells and other monitoring sites can be helpful for gathering long-term data.

Several different clients utilize our geotechnical services. Tampa engineers, including civil engineers, along with developers, property owners and other companies.

Foundation Drilling Tampa What is Foundation Drilling and Why is This Technique Utilized?

Tampa engineers may turn to a geotechnical drilling firm like Amdrill, Inc. for assistance with a foundation drilling project. Foundation drilling can be utilized to improve a structure’s stability, particularly in areas with less-than-ideal ground composition. Foundation drilling can be performed on existing structures that require some added stability or on new construction projects.

Tampa developers and engineers may contact the expert drilling technicians at Amdrill, Inc. to assist with a project involving a building or another structure, such as a wind turbine, communications tower or bridge.

Foundation drilling near Tampa involves drilling at the site of a structure’s foundation, typically penetrating down into the bedrock. Once the bedrock is accessed, metal rods may be inserted and affixed to the foundation. This transfers the structural loads deeper into the earth, reducing some of the load that is placed upon the foundation.

This type of foundation, known as a “deep foundation” can be ideal for areas with soil instability, as is commonly the case in Florida, where we have an abundance of wetlands and sandy soil which can necessitate the creation of a deep foundation, particularly for large structures.

Florida also has a high-water table, meaning that the ground is saturated with water at a fairly shallow depth. This is one of the reasons why Florida homes generally do not have basements. As a result, you can end up with a situation where you cannot create a sufficiently large and deep foundation or footing.  This results in more widespread usage of foundation drilling for the placement of anchor rods that shift the loads down below the shallow subsurface layer and into the bedrock.

We may also perform foundation drilling in cases where the integrity of the concrete and the underlying earth may be in question. We can drill and extract a cylinder of concrete (better known as a core sample) from the structure’s foundation, which is then sent out for testing to evaluate the quality and strength of the building materials.

In other cases, if the foundation appears to be cracking and deteriorating in an abnormal manner and the integrity of the underlying earth is in question, our geotechnical drilling crews can drill into the ground to extract core samples and perform testing to determine the density and other ground attributes. In some cases, we may find that there is an underground void – a potential sinkhole site – which requires remediation.

Drilling Tampa What Types of Projects Involve Geotechnical or Environmental Drilling?

Tampa is home to a diverse range of companies and organizations that may seek out help from a drilling company such as Amdrill, Inc., as we specialize in environmental and geotechnical drilling projects.

But most who think of drilling automatically envision one of Texas’ iconic oil drills or they may think of drilling a water well. And while these are two very common types of drilling, there are a wide variety of other projects that may benefit from environmental or geotechnical drilling services. And that’s precisely what we’ll explore in today’s article from Amdrill, Inc.

What Are the Most Common Uses for Drilling?

Tampa clients turn to our geotechnical drilling experts for assistance with a variety of different environments and locations, from undeveloped land, to densely populated urban environments, to wetlands or even marine environments.

Difficult Access Drilling Tampa What Challenges Do You Face with Difficult Access Drilling?

Tampa developers, property owners, energy companies, environmental firms and a diverse range of other individuals may turn to Amdrill, Inc. for assistance with a project that involves what we call difficult access drilling. Tampa is home to many challenging drilling environments, which can pose many unique obstacles that less experienced firms may be unable to overcome.

So, what are the most common difficult access drilling locations? And how can Amdrill, Inc. help you to overcome this type of obstacle?

Tampa clients may turn to an environmental and geotechnical drilling firm for help with a vast range of different projects, from seeking out underground voids that could collapse into a sinkhole, to evaluating the extent of contamination, extracting soil and rock samples, or evaluating a property for its integrity and suitability for a building or development project.

The Tampa Bay area is unique because we have marine environments, canal and coastal wetlands, lots of densely populated areas, and to compound matters, the entire state of Florida is comprised of sandy soil that overlays limestone bedrock, creating conditions that are ripe for sinkhole formation. These factors can make for lots of difficult access drilling projects.

Here are a few of the most common challenges we face with difficult access drilling.

Tampa and the surrounding area has a high population density – Which means that we encounter many cases where we must maneuver our drilling rigs and vehicles around structures, fences and a variety of other obstacles. Fortunately, we have several different drilling rigs and vehicles that allow us to access and drill in even the most challenging, densely populated locations.

Tampa has lots of marine environments – Which can make for challenging drilling projects. It can be difficult to maneuver a large drilling rig and a boat or amphibious vehicle with a sufficient degree of stability into many marine environments, including wetlands, rivers and canals. What’s more, undeveloped regions of Florida – including those surrounding Tampa proper – tend to feature extremely dense, jungle-like vegetation. We have lots of rugged vehicles that can access these locations, including vehicles with tank-like tracks and ATVs.

Florida is very prone to sinkhole formation – Which makes sinkhole investigations extremely challenging. The weight and vibrations from a drilling rig and its accompanying vehicle could be sufficient to cause a void to collapse into a sinkhole, so this may restrict us in terms of where we can position our equipment. The equation can be complicated further if there are lots of structures in the immediate area, as we must work around those structures. Underground imaging, such as ground penetrating radar can be used to locate underground voids, enabling us to position our vehicles and drilling rigs in a safe location.

If you’re seeking a geotechnical drilling company that specializes in difficult access drilling, Tampa area natives can turn to the expert team here at Amdrill, Inc. We have experience with a broad range of challenging drilling environments and we even have several smaller portable drilling rigs that have allowed us to perform drilling operations inside structures! Our many vehicles and drilling rig models give us the flexibility we need to access and drill in virtually any location.
