Pipebursting operations create outward ground displacements. These displacements tend to be localized and dissipate rapidly away from the bursting operation. The bursting operation also can cause ground heave or settlement above or at some distance from the pipe alignment. Critical conditions for ground displacement occur when the pipe to be burst is shallow and ground displacements are ...
Concrete is one of most durable manmade materials, but even this old industry workhorse has its weaknesses. Exposure to harsh weather, reactions with common elements, and poor construction can all lead to concrete failure.
