Technical Survey and Analysis for Foundation Repair or Retrofitting (Part-1)

Dear reader we will publish series of posts about foundation repair and retrofitting in this blog. At first we like to introduce technical survey and analysis required before taking decision for foundation repair and choosing method of foundation repair.


Any types of retrofit work of large scale should be supervised by professional to evaluate structural and geotechnical conditions in and around the foundation. As extensive repair are very expansive we should be very careful about feasibility of repair and also method of repair and a detail survey followed by analysis is required.


Excavating trench for foundation to be retrofitted
A historical survey is required to have information about foundation or foundation walls. The extent of survey and subsequent analysis depend on the following:

  • Size of to be retrofitted building 

  • Age of building 

  • Condition of building foundation 

  • Change in use of buildings etc.
Seismic retrofitting of steel tank with concrete foundation
From this survey we will evaluate condition of foundation which will define whether a foundation can be retrofitted economically or not. We have already learnt about cost involvement in this process. A tolerable amount of cracks and tilts is considered enough not to retrofitted when settlement is stopped or further settlement is unlikely to happened.


Dear reader we will learn about different types of surveys that should be included in this survey in next part of this post. Please stay with us.
