When a road turns into a raging river, it becomes both dangerous and damaging. This is exactly what happened in July 2013, when the city of Lebanon, N.H., was swamped with more than 4 in. of rain within 48 hours—2 in. fell in just 45 minutes. The deluge caused flash flooding, which left residents stranded and cost $6.5 million in infrastructure damage. The biggest chunk—$3.4 million—was slated to repair Slayton Hill Road,[url=http://maintenancemachineprice.com//crack-repair/cheap-rubber-bridge-expansion-joint.html]cheap rubber bridge expansion joint[/url] which was washed out during the storm.
According to city officials, washouts on this road had been an ongoing problem. Stantec Engineering (formerly Fay, Spofford & Thorndike) was asked by the city to assist with the design of emergency repairs and tasked with coming up with a more resilient solution.An additional challenge was to complete the project quickly to keep traffic moving and allow access to residents,[url=http://maintenancemachineprice.com//crack-repair/pavement-irregular-fractured-humerus.html]pavement irregular fractured humerus[/url] including a housing complex at the bottom of the hill. The solution needed to reinforce the land along the road in a timely manner, as well as be durable enough to withstand salt spray and aesthetically maintain the character of the scenic roadway. Based on these criteria, Redi-Rock was chosen for the job.“Slayton Hill Road is a vital throughway for many Lebanon residents,” remarked Bryan Sicard, a local Redi-Rock Representative.Eric Merluzzi, P.E., Independent Wall Designer explained, “Using Redi-Rock gravity walls up against a bank saves excavation work, which speeds up the project and is more economical. Along with the drainage pipes,[url=http://maintenancemachineprice.com//crack-repair/routine-road-maintenance-manual.html]routine road maintenance manual[/url] a stable retaining wall will prevent future washouts.” Redi-Rock is an engineered precast retaining-wall system that uses one-ton blocks that stack up like giant Lego blocks. Because the blocks are so massive, the Redi-Rock system can rely on gravity to hold the wall up in many applications. Gravity walls require less excavation,[url=http://maintenancemachineprice.com//crack-repair/canadian-tire-concrete-crack-repair.html]canadian tire concrete crack repair[/url] minimizing disturbances to nearby homes and infrastructure. Because each block is manufactured using architectural-grade precast concrete, Redi-Rock walls can stand up to harsh elements. |
