Delamination Problem Requires Multi-Layered Approach

Post by:

RJ Lee Group was retained to investigate the cause of the delamination of acoustic fireproofing applied to steel beams of a number of large public facilities. To examine the materials in-situ, we worked in collaboration with a well-known fire protection expert already retained by the client to assess the situation. During inspection we investigated several […]
