Excess moisture can be present in concrete and affect the integrity and durability of the entire structure. High moisture content can cause paint to blister, floor coating to paint, and other problems associated with coating damage. Hence, concrete moisture testing must be conducted using a high-quality device that can provide accurate results. One of the tools you can use in this test is the relative humidity (RH) meter, which is a small and compact sensor that can conduct measurements and provide accurate readings quickly. Relative humidity testing identifies and monitors concrete moisture levels easily and fast in a minimally destructive manner. This way operators can save time and money. An advanced RH meter for concrete moisture testing minimises damage to the concrete’s surface while reducing the time it takes to set up. The minimal air volume on the test sleeve enables humidity equilibrium to be processed quickly and easily. When using an RH meter, you need to follow ...

The right equipment and service can make a difference in your project’s results and turnaround time. If you require non-invasive scanning of a subsurface, consider a ground penetrating radar service, which can help speed up the progress of your project while ensuring accurate results. Ground penetrating radar (GPR), is currently the most advanced non-destructive testing method for scanning what is located underground. Here are six reasons why this service is great: No need to excavate – Engineers used to order excavations or rely on schematics to determine what is beneath the surface. Ground penetrating radar eliminates the need to excavate the ground. The device is not likely to miss on certain details, and the service itself is more cost-effective and faster than excavations. Good for many applications – GPR uses electromagnetic waves, to bounce off any objects they hit underground. The signals then bounce back to the device and the exact location of the objects...

The ground penetrating radar system is quite a useful tool with its ability to locate underground utilities with relative ease. It ensures the safety of existing construction beneath the ground while excavation is in progress for new constructions. Ground penetrating radar can also be used on concrete surfaces. Here is a blogpost telling you about applications of ground penetrating radar on concrete surface. The most impressive use of GPR in concrete is to locate the reinforcement bars inside. There are times when drilling or other invasive operation is to be carried out in a concrete structure. To ensure that sufficient cover is left for the rebars, GPR is used to map the mesh inside the concrete form. The ability of GPR to distinguish between layers of different materials helps to map interfaces between concrete and other surfaces. This comes in handy while determining pavement thickness, as the radar detects soil-concrete interface.So many important applications of GPR are ...

Excavations used to be the practice when it comes to locating utilities, but with utility locator tools, the process has become safer and quicker. A utility locator device is used in non-destructive testing to find problems, cracks, and manufacturing or structural defects in a surface or material without damaging anything. The most important advantages of using this tool involves savings in terms of the time, money, and effort needed for excavations and destruction of the structure, and it makes the job of locating hidden objects safer, quicker, and cost-effective. Here are the different types of tools used for finding utilities: ·        Pipe locators – When locating pipes, you can use either passive or active tools. Utility locator systems make a sound when a pipe or leak is detected. Active locators may yield complex results, as it will detect both the pipe and the leakage on other pipes and try to stop or minimise water leakage. Once the utilities...

Final protective coating on products ensures its enhanced life cycle and is hence an extremely important part of the manufacturing process. Whether or not the coating chemistry will work depends on achieving the right adhesion. Testing for adhesion has been simplified with tools like the Pull-off Adhesion Tester that measures how adhesive coatings are on different surfaces such as metal, wood and concrete.   Let’s take a look at some of the features that you should be looking at before you buy that tester- How accurate your equipment is: Since the entire objective of the instrument is to measure the required force to pull coating off a particular surface, accuracy is of prime importance. Achieving an accuracy level of ±1% is recommended and desirable. Compliance to both national as well as international standards provides some degree of reliability. Moreover, self-aligning dollies are a great way to ensure that readings are accurate on all kinds of surfaces. ...

Non-destructive testing is typically favoured over conventional destructive tests as it helps save money and time, especially when examining materials like concrete. Concrete geometry testing involves a range of equipment that can determine rebar location and cover foundation depths and slab thickness. The following is an overview of concrete geometry testing equipment and their importance for the job: Foundation test gauge – The device is a compact shaft and pile inspection tool that uses sonic echo testing method, which is also known as ‘pile integrity test’ (PTI). Sonic echo investigations are conducted to determine the length and integrity of deep foundations. They may be conducted on a shallow wall structure, too, and on different materials such as steel, concrete, and wooden piles. The various applications of a foundation test gauge include week and uncured concrete in cast piles, determining the foundation depth, and assessment of the condition of foundations. It may be us...

Paint thickness gauges are widely used to measure the thickness of the paint coat on any surface. Mostly their application is industrial, with the widest range of uses arising in the construction industry. They are used for compliance purposes, measuring coating thickness on materials and many other uses. There are many types of paint gauges available in the market. What works best for your application needs to be carefully selected. Here is an overview of types and applications of paint thickness gauge . Types of gauges While these gauges cannot be distinctively classified into categories, there are certain variants available which help in measuring the thickness of the coating on different surfaces. The digital gauge is popular due to its ease of use and direct output. One can place this device on the surface to be measured for thickness and get the results on the LED screen as a convenient read-out with preferred units of measurement. The second kind of thickness gaug...

California Bearing Ration is the test which is carried out, in a very indirect way, to find out the thickness of pavements and layers in road construction. The principle lies in using a penetration equipment on a prepared soil sample and then taking ratios of it with a standard value; this results in an empirical curve which is then analysed to work out the thickness of pavements. In this blogpost, you will get to know the basic procedure of California Bearing Ratio (CBR) test . Procedure: ·          Weigh the empty mould for accurate results. ·          Assemble the mould and attach the collar over it. ·          Add water to the specimen and start compaction as per the Standard Proctor or the Modified Proctor test. ·          When compaction is complete, remove the collar and use a cutting edge to level off t...
