Whether you’re building a new home or renovating an existing one, chances are you’ll need to perform a number of concrete repairs. One of these is to repair a damaged concrete wall. Luckily, there are several ways to do this, but one of the easiest is to use concrete coring.
Stitch drilling
Using stitch drilling for concrete coring is a clever way to remove large slabs of concrete. The technique is usually used when the diameter of the drill is too small to bore a square hole. Stitch drilling is also popular for holes with irregular shapes, such as holes for windows or doors.
Stitch drilling is also used to create openings through concrete walls or floors. Stitch drilling is also a good option for creating larger holes than a hand saw can accomplish.
Diamond stitch drilling creates holes in concrete that are in a stitch-like pattern. It is also the most efficient way to create holes of virtually any size. Diamond tipped core barrels come in a range of diameters, from 12mm to 600mm.
Stitch drilling for concrete coring can be used in many applications, including for window and door openings, lift shaft openings, and crane base removals. It is also commonly used for smaller holes that are more difficult to drill using traditional saws.
Circular cuts in walls
Whether you’re a construction manager or you’re a homeowner, if you want to run electrical, phone, plumbing, or HVAC lines through your home, then you’ll need to have a core hole. This is a large hole that’s cut through your concrete wall.
To make a core hole, you’ll need a specialized drilling tool. The most common tool is the diamond core drill. Unlike other types of drilling, it makes round holes in concrete that are consistent in diameter.
For larger holes, a drill rig is often used. This is especially useful if your wall is thick or you have limited space. The advantage of using a drill rig is that you can create a hole that’s large enough to accommodate cable lines or phone lines.
If you’re building a home, you may need to install a sewer line. Depending on your needs, you’ll also need to make a core hole for water and phone lines. This is a common requirement for any type of construction project.
Airport runway lights
During the runway safety project at the airport, the airport team realized that the lighting system was not up to par. The project leaders decided it was time to install a new system.
The new system includes new approach lights, taxiway lights, runway edge lights, runway threshold end lights, snow plow rings, wave-off systems, communications and fiber optic cabling. The contractor will be compensated for all of the assembly and installation.
New light fixtures were installed in concrete-encased bases. The existing system was a combination of stake-mounted light fixtures. This type of lighting required high levels of maintenance.
The project team determined a temporary jumper concept was necessary to connect the existing circuit to the new light fixtures. Originally, this was intended to replace the existing light fixtures. However, the project engineers found that the circuit was not compliant with the new light fixtures. This was due to the age and condition of the circuit.
After a careful inspection of the existing circuit, the project team decided to install a new system. The new system required a 3,000 foot home run to the electrical vault.
Investigating the condition of existing concrete
Having the right information and analysis is important in investigating the condition of existing concrete structures. This is a crucial task that needs to be completed by a qualified structural engineering team. Before starting the task, the team must establish the scope of the study. They should also review the construction documents and specifications available. The team should also document the condition and distress of the structure.
The first step in investigating the condition of concrete structures is visual inspection. During this phase, the team will review all available documentation to find out the extent of distress and its cause. In addition, the team will take note of structural observations and conduct field investigations. The team will also use construction materials testing to document the condition of the structure.
Once the condition survey is complete, the engineering team will be able to document the deterioration of the structure and provide a diagnosis. This will then be used to determine the scope of the investigation. The team will also conduct laboratory investigations to gather further information about the condition of the structure. These tests are usually non-destructive. The team will then be able to develop a database that can be used to produce detailed reports on concrete structures. This database will also allow for sophisticated data search strategies.
