What this work involves
Cracks and movement can have several causes. Gather existing information and arrange assessment before choosing a repair method. Consider the transition between an existing building and an extension.
- Existing drawings and foundation information
- Damage or new load assessment
- Ground and structural information
- Suitable methods
- Monitoring and completion records
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Design structural function, connections and visible finishes together.
What the drawing needs to explain
Detail one connection with structural dimensions, visible finishes and adjoining materials. Have required protection measures and service space explicitly assessed.
Decide this before construction
Coordinate the visible detail before producing structural elements. Plan services and finishes early so unwanted boxing does not later surround a deliberately exposed connection.
Cost factors for this service
Investigations, access, method and scale determine the cost. Floor area alone is usually insufficient for a reliable estimate.
Bring this to the discussion
Damage photographs, building age, earlier reports and plans.
Questions about the work
Does every crack mean foundation failure?
No. Cracks can have other causes. Their nature, development and relationship should be assessed before drawing conclusions.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
