STRUCTURAL INVESTIGATIVE AND REHABILITATION SERVICES FAQs
What counts as a structural repair?
A structural repair refers to restoring a building’s structural elements that have been damaged or weakened over time. It can include repairs to load-bearing walls, beams, columns, foundations, and slabs to ensure the building’s safety and functionality.
What is an example of a structural repair?
What is structural fixing?
Structural fixing involves the corrective actions to fix issues within a building’s framework. It includes applying various techniques and materials to mend or enhance the building’s structural integrity, such as welding additional support to a steel frame or using concrete injections to repair cracks.
What are the basic structural repairs?
Basic structural repairs can range from patching minor cracks in concrete, reinforcing steel elements, and replacing damaged bricks in load-bearing walls to more comprehensive solutions like retrofitting buildings for earthquake resilience. The goal is always to address the deterioration and restore the structural system to its intended performance level.
