During the revolutionary war, General Washington burned the wooden bridge over a small brook in the Northeastern United States to delay the advance of Cornwallis’ army. Immediately after the war, the bridge was rebuilt with stone and survived for nearly 200 years until a massive rainstorm coupled with an impact from a drunk driver to the stone guardrail jeopardized the Eastern abutment wall.
The state Department of Transportation called GeoStabilization International® to stabilize the failing abutment using a combination of drilled SuperMicropiles™ and SuperNails®. In a matter of days, the abutment was fixed and ready to withstand centuries of continued service.
