Krannert Hall

CTLGroup was retained by Purdue University to identify the source(s) of reported water leakage associated with the replacement of its vertical strip windows in Krannert Hall.

During our investigation, our team utilized various tests and techniques including thermography, water penetration testing, and partial disassembly to identify and document numerous sources of water leakage. We identified improperly located, failed, and improperly designed sealants among many of the windows. We also eliminated both the limestone and granite cladding as source(s) of leakage.

CTLGroup recommended that all failed sealants should be removed and replaced, including, in some instances sealing the window frames to the adjoining stone, and using spray foam sealant in the open joint of the stone cladding to reduce future moisture and air infiltration. Second floor windows should be re-installed and external pressure plates should be re-attached with a wept, break metal, head flashing above each window head. Hooded weeps at the vertical mortar joints should be installed to drain the flashing while minimizing moisture entry from windblown rain.
