Air sealing is a comprehensive service that also involves eliminating cracks, crevices, and leakage points around windows, doors, vents, and all other openings in your buildings — or anywhere else for that matter. The principle is simple: if you’re heating or cooling a leaky house, you’re...
These bladders or hoses can eventually be burstable by the pressure applied to them from the sheet, whereupon the out-flowing sealing material is sucked into the surface cracks by the negative pressure inside them. Primarily water, but in some cases even some of the sealant will flow out ...
Wall plates in attics. Partition and exterior walls are typically framed with truss chords fastened to the top plates. Once the ceilings are hung with drywall, you generally end up with hundreds of feet of cracks on either side of the top plates open to the attic. Each stud bay in the ...
crack-free concrete foundation hinders the passage of termites. However, most slabs have some minor cracks in them are created as a result of movements induced by stress, drying shrinkage or temperature variations. In this regard, studies have shown that termites can pass through a crack as smal...
“prefoam” my houses by having one of my carpenters detail all the cracks and penetrations with canned foam and caulk. We focus on breaks in the framing, penetrations, overhangs, mechanicals, and where framing meets the foundation. I initially used lots of caulking for sealing these areas, ...
decreased significantly. During the heating process, the free water and partially bound water inside the concrete produced water vapor pressure, which caused micro-cracks and the concrete to be strained, resulting in concrete damage and a decline in the axial compression strength and splitting ...
In the failure stage, as the impact load continued to increase, the concrete specimen continued to absorb energy, forming micro-cracks inside the specimen, and the concrete specimen finally broke into small pieces along the main crack. However, under the impact load, the specimen treated at 400...
