Foundation heave is the movement of expansive soil due to changes in its moisture content. 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 ...

What are the Signs of Soil Subsidence?
Subsidence is the downward movement of the ground underneath a building due to the withdrawal of moisture. This leads to the sinking of the foundation, which compromises the stability of the structure. When moisture is extracted from the soil, shrinkage ...
Construction Techniques for Cast-in-Situ Reinforced Concrete Pile
A pile foundation is considered for construction whenever the load of a structure is large, and a thick and weak soil layer is present below. It is a type of deep foundation that transfers the load of the superstructure to a ...
Repair Methods for Foundation Heave
Foundation heave is a serious structural issue that should be fixed as soon as it is diagnosed. The first step involves the identification of the cause of heaving. This enables the engineers in implementing the appropriate solutions. One of the ...
What are the Signs of Foundation Heave?
Foundation heave is the upward movement of the expansive soil layer after it is saturated with water. Controlling the signs and symptoms of foundation heave at an early stage is important to prevent further enlargement of heave pressure and avoid ...
What are the Causes of Foundation Heave?
Foundation heave is an upward movement of the foundation due to soaked expansive soil. The factors that lead to the saturation of soil beneath a foundation are seasonal changes in moisture, underground aquifer, or leakage in underground pipes. It is ...
Submerged Floating Tunnel: Principle, Features, and Challenges
A submerged floating tunnel (SFT), also called Archimedes bridge or suspended tunnel, is a tunnel that floats in water supported by its buoyancy (specifically, by employing the hydrostatic thrust, or Archimedes’ principle). Tunnels in water are not new in civil ...
Tunnel Shafts: Types, Construction, and Advantages
Tunnel shafts are vertical passages that connect the ground surface to the tunnel roof. 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 ...
