History
The foundational goal behind the development of SR Adhesive was to solve problems inherent with some of the construction methods used on old buildings that were caused by a focus on fire prevention. 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 solution for Unreinforced Masonry (URM) and Under-Reinforced Concrete buildings that repurposed injected construction adhesive as a structural bonding and strengthening material. Through extensive testing and evaluation the founders of SR Contractors refined the product chemistry and developed installation methods and quality control standards that became the basis for all our wall systems.
SR Adhesive 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 Adhesive provides a way to cost effectively enhance an existing buildings ability to resist seismic forces while helping develop 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 Adhesive for structural improvements is the energy absorption abilities of SR Adhesive which can be provided for use in evaluating a building with respect to current energy codes.
SR Adhesive is a closed cell, two part liquid installed material that has high bonding strength, is able resist moisture intrusion, helps to reduce sound transmission and provides additional insulation value to buildings (R-6 per inch of thickness). The strong bond strength of SR Adhesive provides good structural performance and the installation process tends to be less labor intensive, cleaner and less 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.
