This is a new revolutionary method for seismically upgrading existing masonry structures. The cost can be drastically cheaper compared to conventional seismic upgrades. Spray on Foam + Coatings works with SR Contractors in SW Portland on seismic rehab projects. For bids, please contact SR Contractors: 503-246-1480.
As discovered in the 1989 Loma Prieta earthquake, unreinforced masonry buildings have limited capacity for resisting seismic loads. They are susceptible to wall collapse caused by out-of-plane loads from seismic forces.
Masonry Composite Earthquake (MCE) Rehabilitation System
Engineered to help unreinforced masonry buildings better resist seismic activity, the MCE Rehabilitation System counts on an injection of urethane foam into wall interstitial space, providing stability to keep walls standing during even the more intense of earthquakes.
The Technique Is Safe
Skilled technicians inject flowing urethane foam into wall cavities. The urethane bonds to interior wall surfaces. When the foam hardens, it has the structural properties to support clay tile walls in event of seismic activity.
The urethane foam itself can be described as a “sticky, superglue-like substance.” It forms a highly aggressive permanent bond with the clay tile, reinforcing against the effects of an earthquake.
Minimal Disturbance to Existing Space
Whereas other techniques involve the placing of a metal stud wall in front of the existing wall, MCE does not require the addition of another wall; it does not encroach in any way on hallway or room space.
Additionally, MCE leaves wall finishes mostly in tact. Only a small access hole is needed to inject the urethane foam, leaving the other wall finishings entirely unaffected.
Cost-Effective and Expedient
MCE reinforces clay tile walls at lower cost and in less time than other techniques.
In fact, Portland Public School District saved over 75% using MCE, in comparison to traditional methods.
Added Benefit of Insulation Against Heat Loss
Urethane foam is a highly insulative material, providing superior resistance to heat loss. In addition to making an unreinforced masonry structure much safer in event of an earthquake, MCE will help building owners save on energy bills!
Earthquake-Proofing for Unreinforced Masonry Buildings in Portland, OR
Seismologists studying the Cascadia Subduction Zone have predicted there is a 1 in 3 chance of a major earthquake hitting the Pacific Northwest in the next 50 years.
Taking appropriate measures to strengthen unreinforced masonry buildings is essential for preserving the longevity of the structure, and, even more importantly, protecting building occupants from injury or death due to structural collapse.
