Pipe inspection using a camera, also known as CCTV (closed-circuit television) pipe inspection, is a method of inspecting the interior of pipes, sewers, and drain lines to detect any damage or blockages. This method is commonly used in the maintenance and repair of drainage systems, plumbing systems, and other underground infrastructure.

The process typically involves inserting a small camera, mounted on a flexible rod, into the pipe. The camera is connected to a monitor or recording device that allows the operator to view the inside of the pipe in real-time. The camera is equipped with a light source to illuminate the pipe, making it possible to see any cracks, blockages, or other damage that may be present.

The camera is usually moved through the pipe using a winch or push rod, allowing the operator to inspect the entire length of the pipe. Some cameras also have pan and tilt functions which help the operator to take images from different angles of the interior of the pipe.

The inspection results are recorded and can be saved for future reference. The footage can be used to create a detailed report of the condition of the pipe, including the location, size, and severity of any damage or blockages. This information can then be used to plan repairs or maintenance work.

CCTV pipe inspection can be done for various types of pipes such as, PVC, Cast Iron, Steel, AC and Concrete. The choice of camera and method of inspection will depend on the type of pipe and the condition of the pipe.

Ground Penetrating Radar (GPR) is used to identify subsurface features and characteristics without the need for excavation. The process involves emitting a radio frequency signal into the ground and measuring the reflections that return to the surface. The reflection data is then used to create a cross-sectional image of the subsurface.

Knowing the location of an oil tank is important for a number of reasons:

Safety: If an oil tank is leaking, it can pose a serious safety hazard to the environment and nearby residents. Knowing the location of the tank can help prevent leaks and spills, and ensure that any leaks or spills that do occur are quickly contained and cleaned up.

Environmental protection: Oil leaks and spills can cause significant environmental damage, including contamination of soil and water. Knowing the location of the tank can help prevent these types of incidents, or minimize their impact if they do occur.

Property value: Knowing the location of an oil tank can affect the value of a property, especially if the tank is found to be leaking or otherwise in poor condition. This information can be important for buyers and sellers of properties that may have underground oil tanks.

Compliance with regulations: Many local and state governments have regulations regarding the installation, maintenance, and removal of underground oil tanks. Knowing the location of a tank is necessary to comply with these regulations and avoid potential fines.

Cost savings: Knowing the location of an oil tank can help avoid costly mistakes, such as accidentally digging through or damaging the tank during construction or landscaping projects.

A concrete scan in land and underground surveying is the process of using specialized equipment to create a detailed image of the interior of a concrete structure.

This type of scan is typically done using Ground-Penetrating Radar (GPR) equipment. GPR sends electromagnetic waves into the concrete and measures the reflection to create a detailed image of the subsurface features

Concrete scans are commonly used in construction and engineering projects, such as new building construction, renovations, and remodels, as well as in infrastructure projects like bridges and roads. They are used to locate and map potential issues such as reinforcing steel, post-tension cables, conduit, voids, and other objects that may be embedded in the concrete, which could affect the structural integrity of the building or infrastructure.

Our specialist can detect several types of defects in underground cables, including:

Corrosion: GPR can detect corrosion on metal cables, both on the outer surface and inside the cable.

Cracks: GPR can detect cracks and breaks in underground cables, which can cause loss of power or signal transmission.

Water infiltration: GPR can detect water infiltration inside underground cables, which can cause damage to the cable insulation and lead to short-circuiting.

Splices and connections: GPR can detect splices and connections in underground cables, which can indicate a potential point of failure.

Cable depth: GPR can also detect the depth of underground cables, which can be useful in determining the location of the cable and avoiding damage during excavation or construction.

Cable damage: GPR can also detect damage to the cable insulation and the metal conductor inside the cable.

One of the main advantages of GPS survey is its high level of accuracy. GPS surveying can achieve sub-meter and even centimeter-level accuracy, depending on the type of GPS system used and the correction methods applied. This level of accuracy is much higher than traditional surveying methods, such as total stations or traditional ground-based methods, which can only achieve accuracy in the range of a few centimeters to decimeters.

Additionally, GPS surveying allows for the collection of data in real-time, which eliminates the need for multiple visits to the survey site. It also allows for the collection of data in remote or hard-to-access areas. This can save time and money compared to traditional methods. It also allows for the integration of data from multiple sources, such as satellite imagery, aerial photographs, and field measurements. This can provide a more complete picture of the survey area.

It uses electromagnetic fields to locate and identify underground utilities such as pipes and cables. It works by transmitting an electromagnetic signal into the ground using a transmitter, which induces a secondary signal in any conductive objects that are present underground. This secondary signal is then detected by a receiver and used to locate the underground utilities.

It is to determine the strength, stability and safety of underground structures such as tunnels, mines, and underground buildings. This includes assessing the ability of these structures to withstand loads and forces such as soil pressure, rock stress, and ground movement. The analysis also considers factors such as the geology of the site, the materials used in construction, and the design of the structure. The outcome of the analysis is used to determine if the structure is safe for use and if any modifications or repairs are needed to ensure its long-term stability and safety.

Water leak detection is the process of identifying and locating leaks in water pipes, irrigation systems, and other water-supply systems. There are two methods for detecting water leaks, including:

Acoustic Leak Detection: This method uses specialized listening devices to pick up the sound of water escaping from a pipe. The devices can be placed directly on the pipe or used in conjunction with a stethoscope to locate the source of the leak.

Correlation Leak Detection: This method uses specialized electronic devices that emit a high-frequency sound ad listen for the sound to return. The time it takes for the sound to return can be used to determine the location of the leak.

Utility utility location engineering is the process of identifying and locating underground utility lines, such as gas, water, and electrical lines, using a variety of equipment and techniques. This can include ground-penetrating radar (GPR), subsurface imaging, and electromagnetic induction. The goal of utility location is to locate and map the position and depth of underground utilities so that they can be avoided during construction and excavation projects to prevent damage and maintain safety.
