Draft gauge - draft development

Servi carries tools for measuring cracks in concrete: 

 
Crack ruler

A ruler made of plastic with a scale that measures crack widths. 
It can also be used in corners and other difficult areas. 
The scale goes from 0.1 mm to 7 mm. 

 
Crack loupe

A magnifying glass with a built-in scale. 
Used to see and measure small cracks with high precision. 
Very useful for closely inspecting small cracks. 

 
Crack development meter

A tool that is attached to the concrete to monitor cracks over time. 
It records changes in crack width. 
Helps to understand if the crack is getting bigger and if repair is needed.

We measure crack development in concrete for several important reasons: 

• Safety: Cracks can indicate structural problems that can affect the safety of a building or structure. By monitoring cracks, we can detect and address potential hazards early.
• Maintenance: Crack monitoring helps plan maintenance and repairs. This can prevent small problems from developing into larger and more costly damage.
• Quality control: Measuring cracks provides information about the quality and performance of concrete over time. This is important to ensure that materials meet required standards and specifications.
