ASR and freeze thaw cycles causes concrete to crack,
weakening the concrete, reducing its service life.

For years Balvac has been researching and working to stop ASR, remediate affected structures, and restore service life. ASR can cause extensive damage throughout any concrete structure and recommended repair options typically include tear out and rebuild.

Balvac offers a cost effective alternative to using vacuum impregnation to not only neutralize the spread of ASR, it also restores the structures integrity–increasing is service life. Below are samples from our 20+ years of experience neutralizing ASR.

Robert Purcell Community Center
	Where:	Cornell University, Ithaca, NY
	Problem:	Load bearing cantilevered beams suffered extensive damage from ASR jeopardizing the structure.
	Solution:	Balvac’s Vacuum Impregnated the beams restoring structural integrity without impacting the buildings operating schedule  › Read More

Washington Metropolitan Area Transit Authority
	Where:	WMATA Rail Platform, Washington, D.C.
	Problem:	On-grade platforms suffered server premature deterioration from ASR
	Solution:	Performed in-situ repair using Vacuum Impregnation restored structure’s compressive strength to 6,200–7,400PSI. › Read More

Niagara Frontier Transportation Authority (N.F.T.A.)
	Where:	Buffalo, NY
	Problem:	ASR Damaged Catenary Pole Concrete Foundations
	Solution:	Vacuum Impregnation restored structural integrity and test 10 years later show no further signs of damage from ASR. › Read More
