THS Concepts helps building contractors with their crack monitoring requirements. We setup crack monitoring schemes and monitor crack widths over time. Following each survey, we provide easy to understand graphs and reports.

Our crack monitoring service is typically utilised where building work is being undertaken or subsidence is occurring. The crack monitoring data and reports can help satisfy key requirements and agreements associated with the works.

We have completed and advised on several different projects that have required crack monitoring. We work alongside Party Wall Surveyors and Engineers to ensure that the process is undertaken correctly.
