Chipping is a term used to describe areas of concrete that have cracked and delaminated from the substrate. There are several reasons why husking occurs, including freeze-thaw cycles, the expansive effects of the alkaline silica reaction, or exposure to fire. Cracked or peeled concrete occurs for several reasons and requires immediate attention. Chipping may indicate moisture penetration into the steel reinforcement, which can lead to corrosion if left untreated.

Mike that's really disappointing, or we're not seeing the same thing, peeling is a crumbling or flaking of the masonry surface; in your case, the masonry block, cracks appear as lines or gaps between the surfaces of the material. *I could* see some wear on the edges of such cracks on the outer surface of the block, but no mason would call cracking chipping. With all due respect to your engineers, you may want to look.
My picture is of heavily chipped bricks on the lower walls of a building in the Dosoduro section of Venice, a city increasingly subject to flooding and water damage as tides get higher and storms more severe as global warming progresses. Some concrete blocks, particularly older masonry blocks that contain a high percentage of sand, ash or soil and not enough concrete, may be more vulnerable to water damage and husking damage. Cracks, microcracks, blisters, flaking, chipping or delamination are symptoms of defective concrete that must be removed and then repaired before you can proceed to surface preparation. And, if you have chipping, have it treated as soon as possible to maintain the structural integrity of the concrete as much as possible.
Chipping can also be caused by mineral crystal forces or salt formation as moisture passes and evaporates from the surface of masonry materials, resulting in peeling or peeling of the surface. Common causes of flaking are the presence of moisture, salts, heat and mechanical expansion within the concrete that cause cracking, peeling and chipping, etc. This type of surface failure, known as husking or husking, is more common in colder climates where freeze-thaw cycles and de-icing chemicals are prevalent. Delamination and chipping of a concrete member are undesirable conditions; they not only represent a potential impact hazard in the scenario in which chipped concrete falls and hits a person, but also reduces the cross-sectional area of the concrete member and decreases its load-bearing capacity securely imposed.
Pouring it in optimal condition, using quality concrete and keeping snow out of it and sealing it regularly will help avoid the severity of cracks and chipping and help your concrete look like new for as long as possible. Chipping is normally caused by penetration of water into the masonry surface, often combined with freezing, to expel material flakes from the surface of the brick or masonry block or, occasionally, from the concrete surface. While sealing it will not completely eliminate flaking, it will help reduce the chance of it occurring. Chipping is similar to flaking, except that expansion occurs from deeper into concrete, causing the surface to disintegrate into larger fragments In the email they suggested that I contact a structural engineer who is qualified to respond and evaluate chipping.
An additional consideration is that both delamination and descaling offer greater access of air and water to the reinforcing steel within that member; thus creating a corrosion cycle and increased access for corrosive elements that exacerbate the process with each subsequent cycle. In addition, delamination and descaling require greater maintenance, subsequent maintenance costs higher, and can result in decreased service life of concrete members. .
