The repair needed also differs based on the severity and extent of the cracking. For minor cracks, preventative crack filling is a good procedure that can help prevent future potholes from forming. In the early stages, sealing cracks with crack sealant limits further deterioration of the subgrade due to moisture penetration.
Permeable pavement is commonly used on roads, paths and parking lots subject to light vehicular traffic, such as cycle-paths, service or emergency access lanes, road and airport shoulders, and residential sidewalks and driveways.
Repair in damaged sections is possible, but the reaction will continue. In some cases, when a sufficient drying of thin components (walls, slabs) of a structure is possible, and is followed by the installation of a watertight membrane , the evolution of the reaction can be slowed down, and sometimes stopped, due to the lack of water needed to ...
