Surface indentations, often small and localized, can appear in hardened cementitious materials. These imperfections, varying in size and distribution, detract from the aesthetic appeal and potentially compromise the structural integrity of the construction. For instance, a driveway exhibiting numerous small surface voids demonstrates this phenomenon.
Addressing such deficiencies is crucial for preserving the long-term durability and functionality of structures. Preventing moisture ingress, which can accelerate deterioration processes like freeze-thaw cycles and corrosion of reinforcement, is a primary benefit. Historically, various techniques, ranging from careful mixture proportioning to specialized surface treatments, have been employed to mitigate the occurrence of these flaws and maintain the integrity of the finished product.
