Concealed moisture within a roofing system, in a wall system, or in
many other porous building components has never been desirable. The
hidden corrosion damage to ferrous framing members and decking from
concealed moisture has cost building Owners considerably, and
detecting and avoiding these problems has been an important
engineering endeavor for many decades.
Concealed moisture can prove damaging to the exterior building
envelope, interiors, and below-grade components.
Undetected concealed moisture can ruin building components to
the point of failure. With current media coverage surrounding the
presence and propagation of mold spores, the construction industry
is looking to proven non-destructive moisture detection technology
and time-tested cost effective remedies.
Hixson Consultants, Inc. offers Boroscope,
Dielectric Capacitance Meter and Infrared
Thermographic Imaging to detect and quantify concealed moisture as
cost effective means of assessing building exterior skin, interior
and roofing moisture conditions and thermal performance.
Thermographic images coupled with field experience can better
identify moisture trapped in and under the roofing membrane, in an
insulation component, in a wall system, in cast stone, precast
limestone, and other porous building components. This information is
very timely for evaluation of an existing roofing system for water
tightness, or when deciding between roof replacement and recover
roofing based upon the location and percentage of moisture in the
roofing system.
Wall Systems & Glazing
Offering the following services:
1.
Design recommendation:
Recommendations
on the proper glass and glazing system to be used for the specific
project needs and how to tie the glazing system to the surrounding
exterior waterproofing materials.
2.
Shop Drawing Reviews:
Review
shop drawings for sealant joint location, application and the
compatibility of the sealant with the surrounding waterproofing.
Review the glazing system’s ability to weep water and incorporate
flashing to control migrating water into the building. Review proper
anchoring methods for the type of system and surrounding supporting
structural elements.
3.
Submittal Reviews:
Review
submittals regarding curtain wall, window wall and storefront
glazing systems, glass types for suitability on the project, and
aluminum door review, including hardware comments. Test report
reviews on the glazing system, along with comments on the system’s
installation instructions for proper installation, as dictated from
the manufacturer.
4.
Jobsite inspections:
Jobsite
inspections to verify installation of curtain wall, window walls,
storefronts, and their internal seals as recommended by the aluminum
framing manufacturer. Anchoring, sealant joint sizes and field
application of end dams are usually critical in regard to the
glazing system’s ability to control water. Also, to review that the
materials being used are the materials that were approved for use in
the project.
5.
Spray nozzle testing:
Field
water hose spray testing with a Monarch calibrated brass nozzle to
verify major leaking in windows, perimeter sealants, or wall systems
which follows generally, but not specifically the guidelines per
AAMA 501.2-03. The proper water source and the proper water pressure
are required to accomplish this test along with access to the
exterior of the test specimen. This test will locate large voids in
perimeter sealant or other flaws that can usually be located at the
exterior and repaired easily. This test will not usually pinpoint
internal leaks resulting from system failures caused by internal
deterioration, installation errors or design inadequacies.
6.
Chamber Air and Water Testing:
Field
air chamber water testing to pinpoint (internal or external)
potential problems within glazing systems, perimeter sealant
applications, and tie-in problems with surrounding waterproofing
elements.
