10 Most Common Reasons of Foundation Failure
A foundation is a structural element that provides support for various loads acting on the superstructure. It is the link between the structure and its eventual support, i.e., the soil underneath. The actual transfer of load may be by direct ...
How to Construct Footing for Residential Buildings with Maximum Two storeys?
The construction of footing for residential buildings of a maximum two-story is relatively easy. This is because the imposed load is small, hence problems related to underlying soil can be solved properly with a good degree of certainty. The building ...
How to Use Preloading to Improve Soil Bearing Capacity?
Preloading is an economical and effective soil improvement method that can reduce settlement and increase the bearing capacity of soft soil. In other words, preloading accelerates settlement of the soil before the construction of the structure. Commonly, the combination of ...
What are the Important Pile Integrity Test Methods?
Pile integrity test (PIT) is defined as a qualitative evaluation of the integrity of piles. As per ASTM D5882, pile integrity comprises the material’s physical dimension, continuity, and consistency. The physical dimension includes the length and the cross-section of the ...
How to Improve Soil Properties by Vacuum Preloading Method?
The vacuum preloading method uses atmospheric pressure as a temporary surcharge to accelerate soil settlement and improve its characteristics. The process involves the application of vacuum pressure into a separated soil mass to decrease atmospheric pressure and pore water pressure, ...
What to Do if Estimated Settlement of a Building Exceeds Allowable Limits?
If the estimated settlement of a building exceeds the allowable settlement, then the designer can choose the following methods to cope with the excessive settlement:i. Alter the structureii. Provide deep foundationiii. Change the foundationiv. Improve the characteristics of the soil ...
How to Determine Termination Point of Piles in Construction?
Deciding on the termination point of piles during the construction process is a critical task. The actual pile termination level may increase or decrease and is finalized during the execution of the drilling process. Pile penetration ratio and chisel energy ...
