The cause remains unclear
Several contractors have given conflicting opinions. Measurements allow us to rule out any hypothesis that does not fit the facts.
Building expertise in Luxembourg
Technical surveys
Findings backed by measurements, not impressions: that is what makes a technical conclusion hard to challenge.

A technical survey is built on data. A crack can be measured. A damp wall can be quantified. The fall of a terrace can be surveyed. A surface temperature can be read. Without these figures, an opinion is just an opinion, and an opinion can be argued over indefinitely.
We therefore document every case with the readings appropriate to the defect: crack width and depth, moisture content of materials, surface temperatures, flatness and levels, drainage falls, pipe sections and gradients, and checks at critical waterproofing points.
This data serves two purposes. It allows us to identify the cause with a high degree of certainty. It also allows a defect to be tracked over time, which is often the only way to tell an active movement from one that has stopped.
Situations where we can help
A defect needs monitoring over time
We set up markers and take successive readings, over several months if needed, to track how the defect evolves.
Works need checking before handover
Flatness, levels, falls, plumb, joinery tolerances. We compare against the applicable tolerances rather than a subjective impression.
An insurance claim needs evidence
Photographs, measurements, precise location. A costed, documented claim is processed far faster than a descriptive letter.
A report from the other side needs checking
We review the method used, the relevance of the measurements taken and how solidly the findings support the conclusions.
Why call in an expert
Conclusions you can verify
Every statement traces back to a reading taken on site, with its location and date.
A clear technical framework for discussion
Faced with measurements, disagreements over impressions come to an end. The case moves forward on shared ground.
Monitoring over the long term
The initial readings become a baseline. Any later change becomes measurable rather than assumed.

How the survey works
01
First contact
We define the technical question to be answered and the data needed to answer it.
02
Readings on site
We carry out the necessary measurements, with reference photographs, and record the conditions under which they were taken.
03
Analysis
We interpret the data against the applicable standards and the specific layout of the building.
04
Report
We present the results, the interpretation adopted, the conclusions, and any monitoring that should follow.
The expert report
The technical report keeps three levels clearly separate: the raw measurements, their interpretation, and the conclusions that follow. This separation lets a third party check the reasoning for themselves.
It also states the limits of the investigation, including any areas that could not be accessed and any sampling that was not carried out. This transparency strengthens the document's credibility rather than weakening it.
What the report contains
- Table of measurements and readings taken
- Reference photographs
- Technical interpretation of the data
- Conclusions and level of certainty
- Limits of the investigation and next steps proposed

Frequently asked questions
Depending on the defect: crack width, moisture content of materials, surface temperatures, levels and flatness, drainage falls, and checks at critical waterproofing points.
By default, no. Where a sample opening is genuinely necessary to reach a conclusion, we propose it, with your agreement, and keep the opening as small as possible.
Generally six to twelve months, to cover a full seasonal cycle. A shorter period does not allow a reliable conclusion on whether the movement is still active.
Yes. We review the method, the measurements, the assumptions made and anything left out, then provide reasoned technical observations.
They establish the technical cause. Legal liability is then determined from the contract, the guarantees and the applicable rules, working alongside your legal adviser.
Yes. Where structural calculations or a soil study are needed, we specify what should be studied and incorporate the results into our own analysis.
