PCB in Caulk
Polychlorinated biphenyls (PCB) are a group of manmade chemicals that were introduced in the 1930’s due to their chemical stability, non-flammability, high boiling point, and insulating properties.

Concrete Slab Delamination
Delamination is a common type of concrete slab distress. Surficial delamination is when the finished surface of the concrete separates from the underlying slab. Although surficial delamination may not significantly affect the structural integrity of the slab, it increases the susceptibility of the concrete to environmental impacts, decreases durability, hampers functionality, and is not aesthetically pleasing.
ATL Receives Accreditation for ASTM C666 and ASTM C215
ATL has received AASHTO Laboratory accreditation for ASTM C666: Standard Test Method for Resistence of Concrete to Rapd Freezing and Thawing and ASTM C215: Standard Test Method for Fundamental Tranverse, Longitudinal, and Torsional Resonant Frequencies of Concrete Specimens.
Testing of Newly Installed Fenestration Products
Air and water passing through a building envelope can create an uncomfortable environment, increase energy costs, cause property damage, and create health and safety hazards. Fenestration products, including windows, doors, skylights, and curtain walls, are designed to allow the passage of people and light, while restricting the passage of air, water, noise, and debris.
