Los Angeles School Asbestos Abatement: Black Mastic Removal

Asbestos-containing materials can become a major concern when schools, commercial buildings, and other older facilities undergo flooring replacement, renovation, or demolition.
Inland Contractors, Inc. recently completed a large asbestos abatement project at a school in Los Angeles, California, involving approximately 4,875 square feet of asbestos-containing black floor tile mastic located beneath carpet glue and leveling compound.
Because the project was completed at an active school property, the work required careful preparation, containment, controlled removal, wet methods, proper waste handling, and detailed coordination from beginning to end.
This project is a good example of why professional asbestos abatement in Los Angeles involves much more than simply removing an old flooring system.
Project Overview: Los Angeles school asbestos abatement

The asbestos abatement scope consisted of:
Material: Black floor tile mastic beneath carpet glue and leveling compoundQuantity: Approximately 4,875 SFProperty type: School facilityLocation: Los Angeles, CaliforniaService: Asbestos abatement, removal, and manifested disposal
Rather than identify the school or specific areas of the campus, this project highlight focuses on the asbestos removal process itself and the controls used throughout the work.
The size of the project required our crew to work through multiple areas while maintaining controlled work zones and protecting surfaces outside the abatement areas.
What Is Black Mastic?
People searching for terms such as “black mastic asbestos,” “asbestos floor adhesive,” “old flooring asbestos,” or “black glue under carpet” are often referring to an adhesive that was historically used beneath certain flooring systems.
In this project, the identified asbestos-containing material was black floor tile mastic located underneath carpet glue and leveling compound.
One of the challenges with flooring projects is that asbestos-containing material may not be obvious from the finished surface. A room may have relatively modern carpet, tile, or other flooring while older adhesives or flooring materials remain underneath.
The EPA advises that asbestos-containing building materials cannot reliably be identified simply by looking at them. When suspect materials will be disturbed during renovation, proper evaluation and testing by a qualified asbestos professional is important.
Before Abatement: Preparing the School Work Areas

Before removal began, the affected areas had to be prepared for controlled asbestos work.
The original flooring system was still in place when our crews began preparing the work zones. Furnishings and other items were relocated or protected as required, and the work areas were isolated from surrounding portions of the facility.
Containment is a critical part of many asbestos abatement projects because it helps separate the regulated work area from unaffected portions of the building.
For this Los Angeles school project, extensive polyethylene sheeting was installed throughout the affected spaces, including walls, openings, fixtures, and other surfaces that needed protection.
The result was a clearly defined work environment where the removal process could proceed under controlled conditions.
During Abatement: Controlled Flooring Removal
Once containment and required preparations were established, the flooring system could be removed so the asbestos-containing mastic beneath it could be addressed.
Our project photos show the process progressing from the existing finished flooring to exposed flooring adhesive and substrate within containment.
The removal process was performed using controlled asbestos work practices designed to minimize unnecessary disturbance.
South Coast AQMD Rule 1403 establishes asbestos work-practice requirements intended to limit asbestos emissions during renovation, demolition, asbestos removal, and associated disturbance of asbestos-containing materials.
For contractors performing asbestos work in California, Cal/OSHA's asbestos construction standard also covers activities including asbestos removal, containment, housekeeping, transportation, storage, and disposal associated with construction work.
Wet Method Asbestos Abatement With Amended Water
An important part of this project's removal process was the use of a wet method with amended water.
Keeping asbestos-containing material adequately wet during removal helps control dust and reduces the potential for fibers to become airborne while the material is being disturbed.
Our crew used the wet method throughout the abatement process while removing and working around the flooring materials.
This is one reason professional asbestos removal can look very different from ordinary flooring demolition.
Instead of aggressively tearing out materials as quickly as possible, asbestos abatement requires a controlled process where the removal method, containment, worker protection, waste handling, and site conditions all have to be considered.
4,875 Square Feet of Asbestos-Containing Mastic
At approximately 4,875 square feet, this was a substantial flooring abatement project.
Large asbestos flooring projects require careful sequencing because crews may be working through multiple rooms, corridors, or sections of a facility while maintaining the integrity of the regulated work area.
For a school, minimizing the potential for contamination outside the work zone is especially important.
Throughout this project, our team maintained containment while progressing through the removal of the flooring system and asbestos-containing black mastic.
Asbestos Waste Packaging and Manifested Disposal
Removing asbestos from the floor is only one part of the job.
Materials generated during asbestos abatement must also be properly handled, packaged, and prepared for disposal.
Our project photos show removed flooring materials being securely wrapped and staged within the controlled work area.
The project's scope included manifested disposal in accordance with applicable South Coast AQMD, Cal/OSHA, EPA, and DTSC requirements.
South Coast AQMD identifies the handling and disposal of asbestos-containing materials as part of the responsibilities covered by Rule 1403 for regulated demolition and renovation activities.
Proper disposal is an important distinction between professional asbestos abatement and ordinary construction debris removal.
After Removal: Preparing the Area for the Next Phase

Once the affected flooring materials and asbestos-containing mastic were removed, the project transitioned into final cleaning and preparation of the work areas.
The before, during, and after photos from this Los Angeles school asbestos project show a major transformation:
Before: Finished flooring and occupied room configurations were still present.
During: The rooms were placed under containment while flooring and asbestos-containing materials were removed using controlled methods.
After: The flooring system and affected mastic had been removed, leaving the exposed substrate prepared for the next stage of the renovation process.
We avoid representing an area as having received independent final clearance unless that clearance has been specifically confirmed. The photos shown here document the physical progression of Inland Contractors' abatement work.
Why Asbestos Surveys Matter Before Renovation
Projects like this demonstrate why older flooring should not simply be removed without first understanding what materials are underneath it.
South Coast AQMD requires asbestos surveys before covered demolition and renovation activities so that asbestos-containing materials can be identified before they are disturbed. The agency states that applicable surveys must be performed by a Cal/OSHA Certified Asbestos Consultant (CAC).
EPA asbestos regulations also require thorough inspection before certain regulated renovation and demolition work begins.
Inland Contractors, Inc. performs asbestos abatement and removal. We do not perform independent asbestos testing. When testing or a survey is needed, that work should be performed by an appropriately qualified third-party asbestos consultant.
Once the asbestos scope has been established, our team can perform the abatement work required for the project.
Searching for Asbestos Removal in Los Angeles?
Property managers, school administrators, general contractors, facility managers, and building owners commonly search for services using terms such as:
asbestos removal Los Angeles
asbestos abatement Los Angeles
Los Angeles asbestos contractor
school asbestos abatement
commercial asbestos removal
black mastic asbestos removal
asbestos floor mastic removal
black floor adhesive asbestos
asbestos flooring removal
asbestos abatement contractor near Los Angeles
Those searches often begin when a renovation project uncovers an unexpected material beneath flooring, walls, ceilings, roofing, or other building components.
The best time to address asbestos is before those materials are unnecessarily disturbed.
Asbestos Abatement Regulations in the Los Angeles Area
Asbestos projects in Southern California can involve requirements from several agencies.
South Coast AQMD Rule 1403 establishes local requirements relating to asbestos surveys, notifications, work practices, removal, handling, and disposal during applicable renovation and demolition activities.
Cal/OSHA Section 1529 regulates occupational asbestos exposure during construction activities, including removal, renovation, containment, cleanup, and disposal.
Federal EPA asbestos NESHAP regulations establish additional requirements for asbestos during covered renovation and demolition activities.
The exact requirements for any individual project depend on the property, scope, material, quantity, and type of work being performed.
Professional School and Commercial Asbestos Abatement
School and commercial asbestos projects can require significant coordination.
Work may involve:
Large containment systems
Multiple rooms or work areas
Flooring and adhesive removal
Wet method abatement
Controlled material handling
Proper packaging
Manifested disposal
Coordination with consultants, contractors, and facility representatives
The objective is not simply to remove material. It is to complete the asbestos scope using a controlled process that protects workers, surrounding areas, and the project itself.
