Spalling 101: Everything You Should Know
Spalling refers to the process of chipping, cracking, or breaking off small pieces from a material such as concrete, masonry, or metal. Various factors can cause spalling, and the specific types of spalling depend on the material involved. Here are the different types of spalling and their causes for commonly encountered materials:
Concrete Spalling
Freeze-Thaw Spalling:
when water penetrates the concrete, freezes, and expands, causing internal pressure that leads to cracking and spalling.
Chemical Attack Spalling:
Chemicals like acids, sulfates, and chlorides can react with concrete and weaken its structure, resulting in spalling.
Alkali-Aggregate Reaction:
Certain aggregates in concrete can react with alkalis in the cement, causing expansion, cracking, and spalling.
Fatigue Spalling:
Repeated stress cycles, vibrations, or excessive loads can cause fatigue failure in metal, resulting in cracking and spalling.
Corrosion-Induced Spalling:
Reinforcing steel within the concrete can corrode due to exposure to moisture and oxygen, leading to rust expansion and spalling.
Masonry Spalling
Weathering:
Exposure to the elements, such as rain, wind, and freeze-thaw cycles, can cause erosion and spalling of masonry materials like brick or stone.
Chemical Attack:
Similar to concrete, masonry can be affected by chemical reactions, including acid rain or exposure to corrosive substances, resulting in spalling.
Structural Overload:
Excessive loads or improper distribution of weight can cause stress on masonry structures, leading to cracks and spalling.
It's important to note that these are general categories of spalling causes, and specific situations may involve a combination of factors. Regular maintenance, proper material selection, and preventive measures can help mitigate spalling issues. When dealing with spalling problems, seeking the assistance of a skilled professional like Lance Luke can ensure that the repairs are carried out with precision and efficiency, leading to long-lasting and reliable solutions.

14 Common Area Concerns (The Word According To Luke)
VARIOUS SPALLING CONDITION
Introducing our Services
Leading Edge Spall
Leading Edge Spall typically begins with the penetration of water or moisture into the concrete, which can happen through cracks, joints, or porous areas. When this water reaches the reinforcing steel within the concrete, it can cause the steel to corrode. As the steel rusts, it expands, exerting pressure on the surrounding concrete, leading to cracking and eventual spalling.
Full Depth Spall
In the case of full-depth spall, the damage extends entirely through the thickness of the concrete, from the surface to the reinforcement layer. This type of spalling is considered more severe than surface spalling, where only the top layer of concrete is affected. Full-depth spalls can compromise the structural integrity of a concrete element, posing safety risks and requiring prompt attention.
Partial Depth Spall
Partial depth spalling refers to a type of concrete deterioration that occurs when the surface layer of a concrete structure, such as a road or a bridge, starts to break off or chip away in small pieces. It is a common problem in regions with significant temperature variations and exposure to de-icing salts or other corrosive substances.
Vertical Spall
Vertical spalling is a common issue in aging structures and can compromise their structural integrity if left unaddressed. Proper maintenance and repair are essential to prevent further damage and ensure the safety and longevity of the affected structure.
Horizontal/Overhead Spall
Horizontal/overhead spalling refers to the phenomenon where fragments or chips of concrete dislodge and fall from the underside or upper surface of a structure, typically caused by the deterioration of reinforcing steel or other structural elements. It is a form of concrete deterioration that can occur due to factors such as corrosion, freeze-thaw cycles, or excessive loading.
