Crack Monitoring

Accurately measuring and reporting crack movement within 0.1 millimetres.​

• Excavations • Piling • Underpinning • Insurance Claims • Subsidence

Working alongside Party Wall Surveyors and Building Contractors across London & The South East, we undertake precision crack monitoring using gauges and/or pins to accurately report crack movement over time.

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.

Crack Monitoring FAQ's

We primarily use 2 types of crack monitoring devices. One is a tell-tale crack gauge that is secured to your wall and sits either side of the crack. Over time the 2 separate plates move as the crack opens or shuts. We can then read the measuring plate to observe the movement over time.

The other method we use is by gluing small monitoring studs either side of the crack. These studs are less than 10 mm in diameter and have a dimple in the middle to precisely measure to with a measuring calliper.

The crack monitoring process will not significantly damage your wall and will only cause minor areas that may need re decorating. We use glue and small fixings to secure them to the wall so it us usually a case of filling and painting over.

We can usually get the crack monitoring setup and in place within a week of the instruction. It usually takes us a few hours to get everything setup at your property.

Yes, we can suggest positions to monitor however this would need to be approved by you, your Structural Engineer and / or Party Wall Surveyor.

We have been involved in a range of different projects varying in size. Typically, our crack monitoring survey service is applied for projects such as:

  • Basement construction
  • Underpinning
  • Heavy nearby demolition
  • Earth movement projects
  • Settlement and deformation
