Crepitus or crepitation is the noise that may be heard during joint movements, such as a cracking, popping, snapping, or grinding. These sounds and sensations can occur in the neck as well. Most people at some point have experienced neck crepitus. One example is feeling a cracking sensation in the neck when turning the head to back up a car.

Neck crepitus can occur at any age, but it is more likely to occur as a person gets older. The frequency of neck cracking and grinding sounds can vary greatly. Some people might experience neck crepitus a few times a month, whereas others might experience it every day or even throughout the day with most neck movements.
Neck crepitus may go through some periods where it occurs more often than others. For example, neck cracking and grinding might occur frequently for a few days and then go away. In cases where neck crepitus is the result of bone-on-bone grinding due to facet joint osteoarthritis, the neck cracking and grinding sounds are more likely to occur frequently with movements and not go away.
While increased neck cracking and grinding sounds can occur with arthritis, there is currently no scientific evidence to suggest that frequent neck cracking can lead to arthritis. As we age, the sounds tend to move from louder and more pronounced cracks to more grinding or crunching sensations.
If neck cracking or grinding is accompanied by pain, stiffness, or other concerning symptoms, it may indicate an underlying medical condition that needs to be checked by a qualified health professional.
The last 50 years have seen the extremes of people's reaction to movement in buildings. In the immediate post-war years, when we were grateful for any accommodation which had survived the Blitz, attitudes to odd cracks were relaxed. Whilst redecorating my father would summon us children with glee to see finger-wide cracks discovered beneath the wallpaper, before ceremoniously plugging them with newspaper and Polyfilla. No panic attacks for him, whereas nowadays structural engineers are increasingly called out to pronounce upon hairline plaster cracks dramatised by white emulsion paint.
Subsidence, settlement, heave, sway, bouncy floors, bulging walls, cracks, expansion and contraction are all forms of structural movement. Such movement occurs all the time, and usually its magnitude is so small it passes unnoticed. Only when distortions and cracks threaten the use or safety of the structure need we be concerned.
All crystalline materials (stone, concrete and brick for example - see Table 2) expand and contract with changes in moisture-content and temperature. The resultant strain must be accommodated by the structure, or permanent deformations and cracks will occur. If movement is cyclical, then such cracks may grow due to the 'ratchet' effect of debris in the cracks preventing full closure.
Buildings and other built structures are moving all the time, but usually these movements are so small as to be unnoticeable. This movement can be caused by defects, changes in ground conditions, foundation settlement, changes in the building fabric, and so on. However, if the building is unable to accommodate this movement, cracking is likely to occur. The appearance of cracks and other distortions caused by building movement can be visually unattractive and disconcerting for occupants, and if left untreated they can affect the integrity, safety and stability of the structure.
BRE assessed a number of properties as part of a study that was published as BRE Digest 251 Assessment of damage in low-rise buildings. This identified six categories of cracks together with the typical damage caused and the remedy required:
If cracking occurs in buildings, they should first be examined for the likely cause of movement, and assessed to determine whether this is due to an external factor such as subsidence, or is caused by the fabric of the building itself. It is important to establish whether the cracking static, or whether it is likely to be progressive and to deteriorate further, and if so, to what extent and over what period of time. Research of archival information, such as previous surveys or photos, can help with this assessment.
Repair strategies can range from limited cosmetic works to major interventions, however, unless the underlying cause has been dealt with, it is likely that further remedial work will be required in the future. Movement caused for example by vibration or by thermal expansion and contraction is likely to persist. In this case, repair materials must be chosen carefully; those with the ability to deform in a plastic manner will be more successful than those that simply increase strain around the crack and so are likely to cause the repair to fail. For example, hydraulic or fat limes may provide enough plasticity to accommodate strain. Corrosion-resistant stainless steel reinforcements can be inserted into bed joints to reduce the risk of failure by redistributing strain and stress over a wider area.
Rather than simply covering up problems, it is important to understand the reason that cracks have occurred, particularly if they are large, or if they are increasing in size, and it may be wise to seek expert advice, particularly if there might be implications for structural integrity or safety.
When your home is built, be sure to have a professional install the foundation. They must place it in the proper area and complete the drainage and curing process properly. Otherwise, you could end up with several foundation cracks.
Step cracks are a combination of both vertical and horizontal foundation cracks, making them one of the most serious and potentially damaging types. Other examples include map, diagonal, and spalling cracks.
One of the best things you can do when you notice foundation damage is to hire a professional to help with the process. This is especially true if you have serious horizontal cracks that may put your home in grave danger.

Surface Repairs:ElastiPoxy is also handy for filling spalls, pit marks, or holes in concrete, as well as cracking caused by rusting embedded steel. If appropriate, mix ElastiPoxy with sand and trowel the epoxy-sand mix into spalls to provide a strong and rigid repair, similar in appearance to concrete. Check out the Picture Guide for Repairing Cracks in Concrete Blocks.
Unlike China, Hong Kong has numerous political parties. They have traditionally split between two factions: pan-democrats, who call for incremental democratic reforms, and pro-establishment groups, who are by and large pro-business supporters of Beijing. The latter have typically been more dominant in Hong Kong politics. (Historically, only a small minority of Hong Kongers have favored outright independence.) Since 2014, student protesters demanding a more democratic system have formed several political groups, including more radical, anti-Beijing parties such as Youngspiration, Hong Kong Indigenous, and Demosisto. But the power of these groups and pro-democracy parties have weakened significantly as Beijing has cracked down on political opposition, including via the national security law. Several parties have disbanded, and members have been forbidden from running in elections or jailed.
MRI studies have revealed that the displacement of the joint surfaces forming the knee joint can create a vacuum, and the compression of the joints can lead to flow of synovial fluid into the joint, which can lead to the collapse of gas bubbles formed in this process. This collapse of gas bubbles could also lead to knee cracking.
A cracking sound during activities could simply mean your kneecap is mobile and moving. The kneecap moves in a groove located in the knee joint during activities such as walking, running or squatting.
The most common type of foundation crack repair is interior epoxy injections. This solution involves sealing up foundation cracks with epoxy and polyurethane crack injections. The method is both reliable and cost-effective if done professionally. However, epoxy injection repairs when originally issues is not diagnosed properly, a low-quality epoxy is used or repair is made incorrectly.
Structural foundation cracks pose a serious threat to the structural integrity of homes. The repair method involves a combination of carbon fiber countersunk staples and epoxy injections depending on the severity of the crack.
Renco Tip: Foundation weeping title drains can get clogged causing foundation crack and water issues. If you suspect an issue get a weeping tile inspection which can save your foundation from future issues.
