What is a Cone Test? If you want to know the basics, start here

A Cone Penetration Test (CPT) also referred to more informally as a Cone Test, is a way to get at subsurface information without having to directly sample the subsurface. Many organizations that order drilling services are also using CPT within their operations. CPT testing services is a good support option to well drilling services, since many of the potential customers and skills overlap. What is Cone Penetration Testing? Cone Penetration Testing (CPT) is the practice of using an ASTM standard hardened cone shape that is directly pushed into the ground to substantial depths. The cone is pushed using steel rods that are able to be connected to each other in 1 meter lengths as the depth increases. A powerful hydraulic ram is used to generate a substantial amount of downward force to enable the cone to penetrate soils, sand, clay and sometimes even soft rock. In order to keep the surface equipment (truck) in place and not simply be lifted up by the ram force, the vehicles that the CPT equipment is mounted on or in are typically quite heavy. Also, the use of anchor systems to the ground will increase the ability of any vehicle mounted CPT system to push harder and therefore deeper. There are a couple of different imperative goals to any subsurface investigation. The first one is the nature and sequence of strata or soil,sediments and other geological subsurface features. Using CPT for this is called geo-technical testing. In addition, the groundwater conditions can be established during a sounding. CPT can be used to determine: the composition, strength and distribution of subsurface soils. These can range from clay, sand, bedrock, groundwater table, hydrocarbons, contaminants and more. Advantages of CPT There are many different advantages to Cone Penetration Testing (CPT), including, prompt collection and interpretation of field [...]

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 [...]
