Oceanside, California.  One of the largest subdivisions required paint and stucco removal from 7 miles of 6” high block walls.  The walls were located in a high density residential area which made this project very challenging . The residents were concerned about the dust but a dustless sandblasting system and 20/40 crushed glass which has no free silica was a perfect solution. The San Diego Air Quality Management Department was called to the project by the residents and there were found to be no issues that would create an air quality issue.
