Crawlspace Encapsulation ACM Soils, Western New York


  • Encapsulation of 17,000 square feet of ACM soil in crawl spaces of multiple buildings
  • Removal of asbestos-contaminated soils
  • Excavation and saw-cutting of foundations for the installation of trench boxes and access to work areas

SES was retained by a Veterans Affairs Medical Center to provide remediation and encapsulation of asbestos-contaminated soils within multiple crawlspaces.

Significant space restrictions created limited access, as well as type of equipment and remediation methods that could be utilized. Another challenge this project presented was the facility’s need to maintain full operation status.

The remedial activities included the cleaning of all piping systems, collection and management of contaminated water, and segregation and removal of hazardous and non-hazardous soils. SES provided onsite stabilization of liquids and solids, which were then loaded into permitted vehicles and transported off-site via non-hazardous and hazardous waste manifests to an approved facility.

A 15-mil polyethylene barrier was then installed. Following barrier installation, a flowable fill concrete mix was pumped throughout the crawlspaces to encapsulate the contaminated soils. The crawlspace was then cleaned and cleared of all contaminated debris to facilitate further work to be performed by other trades.
