Projects on the Board

Seeing is believing !

In the fall of 2014, Dec-Tam was presented with the unique challenge of abating, remediating, and demolishing a building in Middleton Massachusetts all while preserving its' sister building attached by a foot bridge. We were able to capture every moment of the project through its completion and the results are in this time lapse video. Watch as our highl-skilled crew safely removes all asbestos and PCB material, strategically dismantles the structure and backfills the site.

See for yourself why Dec-Tam is the only answer to all your environmental remediation needs.
