Methods of prevention and remediation of the consequences of differential settlements Foundation remediation by concrete underpinning. Foundation remediation with jet grouting. Foundation remediation with micro piles. Foundation remediation by using expanding geopolymers.

The best way to prevent potential differential settlements is to carry out adequate exploration and investigation works at the location where the structure is planned.

Note: the consolidation settlement can be reduced by conducting any of the following: 1. Increase the length of piles (when the length of piles are increased, H value in the preceding equation would reduce. H is the thickness of the compressible portion of the clay layer).

Differential settlement is the uneven or unequal settling of a building's foundation. This occurs when the soil under your foundation contracts, expands, or shifts irregularly. Differential settlement causes the structure to settle at a variable rate.

Prevention. Uneven foundation settlingdifferential settlementis best prevented by careful analysis of the soil before a building foundation is constructed. The best soils for building foundations are nonexpansivemeaning that they contain little clay or silt content.

Compacting the soil. Draining the soil, in case of cohesive types. Compacting the soil, in case of cohesion less soils. Confining the soil, increasing stiffness.

Optimization Design Based on 03b2 In order to solve the differential settlement problem in a PRF caused by pile-soil interaction and different loads on top of the piles, variable pile lengths are used in this paper to decrease the differential settlement.

Monitoring Settlement Cracks in floor slabs and walls are monitored with crackmeters. Misalignment or separation of incoming utilities or expansion joints can be monitored with jointmeters. Differential settlement of floors and walls can be monitored with hydrostatic level cells.

Doors and windows, sinking of chimneys, bulging walls and sunken slabs are often considered as the adverse effects of differential settlement and can be devastating to a building. These effects are a result of increased axial force, shear force and bending moments in the structure.
