Professional Monitoring Surveys In London
Our experienced surveyors provide precise movement monitoring surveys across London and surrounding areas. With over 11 years of local expertise, we install monitoring systems, track structural movement, and produce detailed reports for buildings affected by subsidence, basement excavations, or insurance claims.



Monitoring Survey Overview
Structural movement monitoring uses fixed targets or prisms to track shifts over time. Data is reported through graphs, triggering investigation if limits are exceeded.
Crucial for projects near shared structures like basement excavations and underpinning, it ensures safety and compliance. With extensive experience in London, we provide reliable monitoring for projects from small builds to multi-million-pound refurbishments.

Monitoring Survey Service - How It Works?
1 - Proposal Plan Produced [Free Of Charge]
If you haven't received specifications from your Structural Engineer, we can provide a complimentary initial monitoring specification document for approval by your contractor or engineer.
2 - Monitoring Scheme Installed
Our skilled surveyors conduct on-site visits and ongoing surveys to track movement over time. We establish survey points and provide guidance on optimal placement during the site visit.
3 - Post Setup Report
After the initial setup, we provide a detailed report outlining key aspects, including point locations, setup positions, and any relevant considerations.
4 - Monitoring Begins
Once you're ready to begin, we’ll schedule site visits at set intervals (weekly, monthly, etc.) to survey the monitoring points. After each visit, we process the data and deliver the results to you.
5 - Removing The Monitoring Points
At the end of the monitoring process, THS Concepts can arrange a site visit to remove the monitoring points. Our cost-effective, disposable targets can also be easily removed by your contractor if needed.

What Projects Typically Require Movement Monitoring?
Basement Construction
Particularly in urban areas where properties are closely packed, such as in many parts of the UK. Monitoring is crucial when excavating for basements to ensure the stability of neighbouring structures, especially party walls.
Insurance
Monitoring surveys often accompany insurance claims as a way of verifying if a building is moving and to what extent.
Underpinning
This is often required for structural stability or as part of basement creation. Monitoring ensures that the underpinning process does not adversely affect the surrounding soil and structures.
Demolition
Monitoring is essential to ensure that the demolition process does not cause damage to nearby buildings, particularly in dense urban environments.

Brilliant service - we were in a desperate position needing to documentation relating to a landlord certificate and they came out the next day squeezing us into their schedule -
Minniedale Projects ★★★★★
We recently approached THS Concepts to carry out a level survey of the screed to the ground floor of a large residential property we were Project Managing. The property was undergoing extensions and re-furbishment work. We had a tight time … More scale to receive the information and THS Concepts delivered quickly and efficiently to meet our deadline. This is the second time we have used them and would highly recommend. -
Billy Buckley ★★★★★
I contacted Tom to carry out a Topographic survey, and cannot recommend them enough. Nothing was to much, and I was kept up to date with everything as it happened! Great company to deal with and reasonably priced.
