The foundation heave occurs in various patterns like doming, edge, cyclic, and lateral movement. Differential movement of expansive soil is more damaging than a uniform heave. It mostly affects lightly loaded structures like one or two-storey structures, highways, retaining walls, […]

This leads to the sinking of the foundation, which compromises the stability of the structure. When moisture is extracted from the soil, shrinkage occurs in the soil, and the corresponding area of the foundation moves downward. Subsidence usually […]

The first step involves the identification of the cause of heaving. This enables the engineers in implementing the appropriate solutions. One of the major causes of foundation heave is the soil saturation underneath the foundation. In this case, […]

Controlling the signs and symptoms of foundation heave at an early stage is important to prevent further enlargement of heave pressure and avoid serious damage to the foundation and superstructure. Common signs of foundation heave are cracked and […]

It is stated that financial losses due to heaving in the United States are larger than those […]

Tunnels in water are not new in civil engineering. Since about the 1900s, several immersed tunnels have been constructed around the world. Bridges […]

Shafts have many advantages and are used in constructing tunnels. When the position and course of the tunnel are correctly aligned and accordingly set out on the surface, shafts are sunk at defined points on the tunnel line to aid tunneling […]
