Many below-grade waterproofing membrane manufacturers require a third-party independent observation agency to be present to monitor membrane installation at appropriate intervals throughout the Project prior to issuing a premium watertight warranty. The purpose of the independent observer is to monitor waterproofing work and report on the observed conditions to ensure that it is carried out in accordance with all the manufacturer’s requirements for issuance of their warranty.

McGinnis Chen Associates, Inc. is a certified third-party warranty inspector for most of the below-grade waterproofing membrane manufacturers and our employees are regularly trained on all of the systems and details.
