Crack Monitoring Surveying
• 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
Crack monitoring is the simple process of monitoring crack in wall / structure for movement. Depending on what the situation is a crack may grow in width or close up. Typically there are 2 ways of monitoring a crack for movement:
- Crack gauges
- Demec Studs
Crack Gauges
Crack gauges come in a variety of different products designed for varying applications. The basic premise is that you glue or mechanically fix the gauge either side of a crack using glue or mechanical fixings. Over time the crack opens and closes, the movement is then illustrated on the gauge.
Crack gauges are very simple to setup and a fairly cheap method of monitoring cracks. You can quickly understand the movement of the crack as there are no further tools required, it just requires you to read the gauge!
Demec Studs
Monitoring studs (often referred to as Demec Studs) area another simple method of monitoring movement of cracks over time. 2 Demec studs are securely glued either side of a crack. Once the glue has set, the distance between the Demec studs can be recorded using a precise calliper.
The Demec studs have little groves in their centres to ensure that the calliper can precisely locate the measuring hole each time. Modern digital callipers can typically give you a very accurate reading. Depending on how much money is spent, readings can be as small as 0.01 mm
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
