The foundational goal behind the development of SR Foam was to solve problems inherent with construction methods used on old buildings. The founders of SR Contractors sought to provide structural solutions to strengthen older buildings for contemporary seismic requirements while minimizing the impact on a building's historical finishes and character. In 2002, the structural engineers that founded SR Contractors saw a potential structural solution for Unreinforced Masonry Buildings (URM) and Under-Reinforced Concrete Buildings that repurposed a two part spray foam as a structural bonding and strengthening material. Through extensive testing and evaluation, the founders of SR Contractors developed the required installation processes and foam chemistry that became the basis for all our SR Foam systems.
SR Foam is used to restrain existing walls against forces that exploit their inherent weaknesses and anchor veneers or other nonstructural materials to the structural elements supporting them. SR Foam provides a way to cost effectively enhance an existing buildings ability to resist seismic forces while providing increased capacity for other lateral and vertical loads the building may experience as well.
Masonry and concrete buildings do not perform well in current energy code analysis. The reason for this poor energy code performance is that these materials, such as masonry, concrete and brick, do not absorb energy in the way that energy codes have provided a method to quantify. An added benefit to using SR Foam for structural improvements is the quantifiable energy absorption abilities of SR Foam which are defined and applicable to current energy codes.
SR Foam is a closed cell foam material that has high bonding strength and is also able resist moisture intrusion, reduce sound transmission and provide additional insulation value to buildings (R-7 per inch of thickness). The highly adhesive nature of SR Foam provides good structural performance and is typically much less labor intensive and invasive to the building finishes than current competing technologies. These features allow building owners to improve their buildings for both safety and performance with less cost and less loss of historical character.
