Harvey Construction is busy with site work at the co-op’s future building location. Because our project is part of Monadnock Economic Development Corporation‘s larger redevelopment of the Railroad Square area, there are many time-consuming pieces that need to be coordinated in conjunction with our project. Please be patient, progress is being made.
Geopiers are a type of foundation support system made of stiff rock columns used to strengthen soft soil. A Geopier is constructed by drilling a hole in the soil, referred to as the Geopier shaft. After drilling, 2 to 4 inches of crushed rock is poured into the shaft and then rammed into the bottom of the shaft with a hydraulic hammer and specially designed Geopier rammer tool to create the pier.
