Locating Underground Utilities

Whether you are going to be digging around your property for home enhancement purposes or you need repairs on your septic system, you will want to make certain that you understand where any of your underground utilities are found. Many times, public utility systems will be run beneath the ground either for visual purposes or due to the nature of their function. Not finding the underground energies prior to excavating may cause a dangerous circumstance or expense you a great deal even more cash in repairs. Fortunately, there are ways that you can inform where these underground energies are found in close proximity to your home.

For the most part, you are visiting that colored lines or flags are utilized to assist mark the place or to denote the presence of specific type of underground utilities. You could even observe that there will be fluorescent spray paint on the ground marking where the lines are placed. In case of a flag, there is typically a logo that is on it that will inform the municipal energy or business that have energies set up below. When it come to sprinkler heads on industrial ground, you will also see them specially marked so that any landscaping teams or construction employees have the ability to find them or contact somebody to  locate underground services.

Whether it is wires underneath the ground, sprinkler systems or piping, it is very important that they are properly marked to help stop any possibility of an accident from happening. These location techniques are vital in case there is any sort of absence of information on out-of-date maps in the location. When you have the underground utilities appropriately marked, you are going to have the ability to determine precisely where they are so that the right amount of clearance can be offered to assist cover all bases.

Concrete Scanning Can Identify Metal Objects Underground

metal detectorIn any excavation project, if underground objects can be detected, a great deal of money, time and trouble can be saved. A technology called GPR, or ground penetrating radar, can perform a subsurface imaging scan in order to provide the evaluation of a site prior to beginning the excavation.

Concrete scanning Brisbane can locate utilities that are buried underground, obstacles and debris, bedrock, old foundations and other underground debris. The technology specializes in finding both metallic and non-metallic utilities including copper, PVC, concrete and plastic pipes and in addition various conduits that in many cases can not be detected in any other way.

This is an ideal way to locate the position of buried utilities, storage tanks, drums, and man made items such as old roads, runways and underground buildings using the exciting technology. Obvious, if you discover a utility line that is underground, and for some reason it is not on anyone’s map or chart, you will be glad that you uncovered it.

The process is not hazardous to the operator of the machine doing the scanning, as it emits only 1 % of the power of a cell phone signal.

The system operates by the sending of a small pulse of energy into a material through an antenna. The strength and metal detector 2the time that the signal takes to return to the device will create reflections that are then picked up by the recovery system and stored on digital media. The reproductions then come out as visual replications of the object, such as man-made objects of pipes, wire, tanks, and the like.

When it comes to locating and identifying metallic and non-metallic objects of various sizes and shapes, this system is very accurate.

GPR has been in existence for the past 40 years, and of course there have been improvements over the years, but it has saved many an excavation project precious time and money by its availability.

Easy Ways to Measure the Thickness of a Concrete Can Help to Ensure Quality and Forecast Problems During Any Modifications to a Slab

Engineers quite often find the need of measuring concrete slab thickness, when they require making some modifications to the slab. They may also need such information when they are planning any additions, or have doubts about the structural stability of the slab to bear present or future loads. When a non destructive method of measuring the thickness of a concrete slab can be of great advantage, this is.

 

Such non destructive testing enables the information to be obtained without having to conduct on site breaking of a slab or even taking cores to get the information. This reduces any need for future repairs to the damaged portion of the slab, which is in a sense weakened by such actual breaking of the concrete. One of the most common of these devices uses ultrasonic frequencies or other systems that propagate vibrations.

The vibration generator produces frequencies varying from 1,000 c/s to 4,000 c/c and these are made to act vertically on the slab whose thickness is required. These vibrations are detected by a pick-up device, which is then moved around till the vibrations of the generator and those detected in the pickup are in phase. These measuring devices are all hand held and battery powered, which makes their use very versatile and allows their use in the most restricted of situations.

Concrete slab measurements are quite often required to ensure quality control in pavements, tunnel linings and other structures that have a continuous plate. Most of these devices are economical and while being very user friendly, are eminently portable. Data produced them can be directly fed into computers and this allows for automatic warning systems to be put into place. These instruments are calibrated using them on slabs whose thicknesses are known and confirmed. Both thin and thick slabs can be measured, and while for thin slabs the range that can be detected varies from 2.8 t0o 22 inches, when the thick mode is used, slabs can be between 10 and 60 inches. This gives a very big thickness of concreterange that allows most structures to be measured. The functioning of these devices is not affected by paints and measurements can be carried out, even through tiles.

Quality assurance and control engineers use these devices constantly in pavements and linings that are difficult to measure after the work is in place, because one side of the slab is no more visible or approachable once the work is completed. Frequently when holes are needed to be drilled in existing slabs to introduce additional services, these devices may be used in conjunction with rebar locators so that the any drilling that is done is done with the full knowledge of what is likely to be encountered during the operation.

Concrete Strength and Density Testing Is Very Important to Determine the Safety of Reinforced Concrete Structures

 

Concrete is such a versatile material that it is very extensively used to build many structures, whether they are for residences, commercial properties, factories, bridges, dams, roads or any structure that requires a durable and strong material. This makes the strength of the concrete being used very vital to ensure the safety of structures.

strength and density concreteThe mix of the concrete is decided by earlier testing of the various ingredients that will be used to make the concrete. These mixes are then made in the laboratory where the desired strength and density of the concrete is then tested. It is then a responsibility of the construction engineers to ensure that the concrete that is manufactured and poured reaches the required strength and density as required by the laboratory and designers.

Normal construction procedures require that samples of the concrete being used is poured into molds to form blocks that can be used to test the strength of the concrete that has been poured into the structure. Building codes are in place which decides the quantum of testing. Concrete density testing gathers strength over time and standards have been set that requires certain strengths to be developed by the concrete over periods of 3, 7 and 28 days. The blocks that have been taken as samples of the concrete have to be kept in the same conditions as the original structure.

The weight of each block is then taken to arrive at the density of the concrete. A number of blocks are taken for each batch of concrete, while tabs are also kept on where this particular batch has been used in the structure. These strengths of all the tested blocks and their densities are noted.

 

 

At times, when the tests show results below what is required, engineers may prefer to go in for other non destructive tests to establish the strength and density of the concrete. There are various methods like rebound hammers, and ultrasonic testing that are in wide use. In very rare cases, quality control engineers may insist on actual load testing of the structure by using dead weight or hydraulic forces and checking that the deflection caused is within accepted standards.

Location of Rebar in a Reinforced Concrete Structure Is Very Important While Carrying out Modifications

Concrete has a very high compressive strength compared to its tensile strength which is very low. It is possible to increase this tensile strength by introducing rebar in to concrete to make a reinforced concrete structure which can then take both tensile and compressive stresses and make for structures that have strength and durability.

 

 

Rebar location service  reinforced concrete needs to be put at very specific locations so that it allows the structure to have the required tensile strength. Building codes determine the distance this rebar needs to be at from the surface of the concrete. Rust formation can cause rebar to lose its form and strength and thus affect the strength of the reinforced concrete structure.

Quite often it is necessary to create new ducts or holes in a reinforced concrete structure to position services or other utilities. When this requires the concrete structure to be drilled through or partially, it is very important to make sure that any such modification is not hampered by the presence of the rebar. It then becomes very important to know the exact position of the rebar, so that any drilling or breaking done does not come across a rebar. While this can negate the entire process of installing new utilities, because of this obstruction, any damage to the rebar can severely affect the strength of the structure.

rebarTechnologies are available that allow the location of the rebar in concrete to be pinpointed, without any necessity for damaging the concrete to locate the rebar. These concrete scanning operations use ground penetrating radar to locate rebar. This allows the exact location for the rebar to be established so that any subsequent operations can avoid damaging them. There are times, when a structure is showing signs of distress, and at such times one of the first things that engineers do is check on the position of the rebar, as any shift from previously designed parameters can lead to weaker structures. Location of rebar in concrete can help engineers to assess the soundness of a structure.
