How do you avoid settlements?
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.
What is the difference between settlement and differential settlement?
After a building has been constructed, some settlement is quite normal. Differential settlement, however, is when a building's piers or foundation settles unequally. Differential settlement can result in damage to the structure, and is therefore, of concern.

What is an acceptable settlement for foundations?
Generally the settlements of shallow foundations such as pad or strip footings are limited to 25 mm (Terzaghi, 1996). Recent studies on (especially small scale) shallow foundations have shown that allowable bearing capacity occur at settlement of between 5 to 10 % of foundation width.
What is uneven settlement?
Understanding Differential Settlement. 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.
How is building settlement measured?
There are several ways to monitor building settlement. These include:Tilt Beam Sensors.Optical Surveys.Liquid Level Sensors.
What causes the most damage to structural foundations?
Soil movement beneath a home's foundation is the leading cause of structural damages.
How many types of foundation settlements are there?
The settlement in the foundation can be classified into two types namely the uniform foundation settlement and the differential foundation settlement.

What causes settlement cracks?
Settlement cracks are the result of the home settling onto its foundation. Typically, these cracks appear at the weakest points of a structure – namely, windows and doors.
