A GINGERBREAD HOUSE GETS READY FOR THE TWENTY-FIRST CENTURY WITH TENSAL SR4

 

When the University of Nevada Reno wanted to convert this 100+ year old house into a business office there was concern about the seismic stability of the cobblestone basement and foundation.  The mortar had about the consistency of a gingerbread cookie and would not have been much help in the event of an earthquake.


Rather than excavate then form and pour a buttress foundation, UNR chose a FiberMatrix Tensal SR4 parge coat, hand packed and trowelled to the entire interior face of the foundation/basement wall.  The high-ductility Tensal—fourteen thousand lbs in all—provided the tensile capacity to reinforce the historic cobblestone foundation.   A savings of about  $75,000 was noted.   Several minor earthquakes since then have had no effect.
