Why Would You Need a Track CPT Rig?

Vertek CPT wants to ensure that you have the right equipment to grow your business. As you are going through the CPT rig purchase process, we’ll have extensive conversations to ensure that we are both on the same page when it comes to where you will be testing, what types of tests you can most easily sell, and which rig or rigs will help you to make the most money. Track Rig Features As you look around our site, you’ll see that some rigs are built on tracks, as opposed to truck beds with wheels. As per with construction equipment, you might expect the tracked equipment to be larger, with CPT rigs the tracked units tend to be smaller. This is because tracked rig CPT platforms are designed to not only traverse and work in difficult terrains, but also to be highly maneuverable around obstacles such as trees, rocks and gulleys. Remember, CPT testing may be specified by your customer for pre-construction activities, meaning that it takes place on a site with little preparation. Having a highly maneuverable platform with low ground pressure can make the difference between you being able to win certain jobs and not. Track rigs are usually designed in order to distribute the weight of the rig over more square inches of contact area. This helps to minimize damage to sensitive areas as well as help the rig not get stuck in less than optimum ground conditions. The overall rig footprints are designed so that the units can be effectively trucked to sites within your service area. Track rigs are designed for deep pushes in tough geologies and the Vertek CPT tracked rigs push from about 10 tons up to 25 tons. With the right combination of weight, ease of maneuverability and set-up features, a tracked [...]

Soil Electrical Conductivity

In terms of measuring soil contamination, measuring soil electrical conductivity can provide useful information for a more complete site characterization study. Measuring sub-surface soil electrical conductivity is becoming less expensive as well as faster and easier. This form of measurement has most commonly been used for measuring physical and chemical soil properties but the ability to pinpoint contaminants is improving, particularly with software designed for the job. How to Measure Soil Conductivity Measuring soil electrical conductivity is facilitated by two different types of sensors, a contact sensor and a non-contact sensor. Contact sensors work by making contact with soil to measure electrical conductivity directly. These types of instruments are most often used along the surface of a field to characterize the soil for agricultural purposes. Non-Contact Sensors Non-contact sensors, as the name implies, function without having to touch the soil directly. This method is based on the measurement of the change in mutual impedance between a pair of coils passed through the soil. Electricity is applied through the coils, which creates a magnetic field. Much like the way an induction motor operates, this magnetic field induces an electrical current in nearby materials that are magnetic. You can assess the level of current induced by measuring the impedance in the operating coils. Passing non-contact sensors down a borehole has been used effectively to establish geophysical properties such as the presence of clay (which may have highly conductive materials distributed through it) and water table levels. In cases where an area is known to have contamination, the identification of clay layers and groundwater distribution can help to estimate where 'plumes' of contamination might be contained orspread underground. In the case of a borehole test, water samples can be gathered directly from discrete depths to confirm the presence of various types of contaminants. [...]

The Advantages and Disadvantages of Geotechnical Boring; Why CPT May be Your Better Option

As we noted in a previous post about Soil Quality, there are a wide range of reasons that 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 using a drilling rig of some kind. Sure enough, there are special kinds of boring tools that will let you drill deep into the ground and extract a sample of the soil at depth for analysis. Advantages & Disadvantages of Geotechnical Boring Using Geotechnical Boring, whether it be small-diameter or large-diameter equipment allows users to see the solid that is extracted. This can be useful for gaining an understanding of the sub-surface topology if a goal is to create a multi-dimensional map of the subsurface Geological conditions. There are significant disadvantages however to using Geotechnical Boring to obtain soil samples for testing. One disadvantage is that the operation of boring is for obtaining samples only, you can't gather data from the boring activity itself and therefore all of this investment in equipment, labor and time provides value only in that it presents a sample for testing. Another disadvantage is that the soil being sampled then needs to be tested using some type of laboratory equipment. This often means removing a large number of samples from the site, getting them safely in an organized way to a lab facility somewhere, hopefully nearby, and waiting for the lab results to come back. If there are apparent conflicts in data, or a particular part of the site needs more evaluation, the entire process needs to be started up from scratch again. Perhaps the [...]

CPT Testing, Part 1: Introduction to the Basic Concepts

If you have ever been curious about the Cone Penetration Testing (CPT) business, you have come to the right place. In today's post we are going to take a dive into the basic concepts and what expanding into CPT can do for your engineering business. Geotechnical Engineers and CPT Testing Geotechnical engineering is a branch of civil engineering that focuses on the engineering behavior of earth materials. Geotechnical engineers have been using Cone Penetration Testing (CPT) for over 40 years to assist in the design and construction of foundations, embankments and other structures. The standardized CPT works by pushing a 55-60 degree cone into the ground at a rate of 1-2 cm per second and is used to identify the conditions in the upper 100 feet of the subsurface. The data compiled from this testing is valuable for assessing the subsurface stratigraphy associated with soft materials, discontinuous lenses, organic materials, potentially liquified materials (such as sand, silt and granule gravel), and predicting landslides or ground settling. The cone resistance in conjunction with the friction ratio can also be used to determine soil types. While these results are often more accurate when referring to textbook soils, there are some major benefits to utilizing CPT techniques as opposed to drilling. In fact, there are a number of different advantages of CPT, including: economically friendly testing, as well as its ability to perform at a fast rate and effective in characterizing large volumes of soil without having to do a large number of laboratory testing. CPT is also accurate, eliminating the possibility of disturbances to soil samples and sample storage. By leveraging CPT results, engineers can determine the best methods for several aspects of design and construction projects. Detect lenses, thin layers and sand stringers. Evaluate the thickness and extent of compressible soil [...]

What to Consider Before Buying a Used CPT Rig

When faced with the prospect of a major purchase, it’s common to look into the possibility of buying used. In most circumstances, this is a perfectly valid option with a number of upsides, the most obvious of which being a lower upfront investment. However, when it comes to buying a used CPT Rig, you might be better off buying a new rig from a trusted vendor. Here’s why. Used Means Used First and foremost, Cone Penetration Testing is too important to leave up to chance. Sure, your used CPT Rig may appear in fine working order and you may have acquired it from a reputable seller, but there’s no getting around the simple fact that a used rig has a higher chance of failing than a brand new one. This point is further compounded when you consider the fact that even the best used CPT Rig dealer can’t match the expertise of a CPT Rig manufacturer. Expertise Straight from the Source When you buy a CPT Rig from Vertek CPT, you’re also getting access to our knowledgeable technical sales staff; something used CPT Rig sellers can’t offer. Additionally, in some instances, Vertek CPT will provide comprehensive training and will even accompany you to your first job site to maximize your chances of success. You can’t get that kind of service or expertise from a used CPT Rig dealer. Even if you think you have enough experience with CPT Rigs to ensure success with a used rig, though, it’s also worth noting that not every CPT Rig is right for every task. A Wide Variety of CPT Rigs If you have a broad enough knowledge base to feel comfortable buying and setting up a used CPT Rig, then you probably also know that there are many kinds of CPT Rigs. Cone [...]
