A structural pathology report is a key technical document used to identify, assess, and diagnose damage affecting a building’s structural elements. This type of report not only helps determine the extent of a construction problem but also prevents major risks and allows for proper intervention planning.
The main purpose of the report is to provide a clear, evidence-based diagnosis that serves as the foundation for making decisions — from minor repairs to complete rehabilitation or urgent safety measures.
What Are Structural Pathologies?
Structural pathologies are defects, damages, or alterations that affect the load-bearing elements of a building and compromise its stability. They can be visible or hidden but always impact the building’s safety, comfort, and durability.
Common examples of structural pathologies include:
- Cracks in load-bearing walls or slabs.
- Ceiling or floor fissures that worsen over time.
- Deformations in beams, slabs, or roofs.
- Foundation settlements.
- Reinforcement corrosion in reinforced concrete.
- Structural dampness damaging load-bearing materials.
- Detachments or loss of adhesion in construction components.
These pathologies may be caused by design errors, poor workmanship, changes in building use, overloading, material aging, soil movement, or external factors such as water or chemicals.
What Is a Structural Pathology Report Used For?
A structural pathology report serves several essential purposes:
- Technical diagnosis: Identifies what’s happening, how severe it is, and how it might evolve if no action is taken.
- Risk prevention: Detects potential hazards before they become critical or lead to collapse.
- Basis for rehabilitation or reinforcement projects: Provides documentation for architects and engineers to design the right solutions.
- Administrative justification: Often required to process permits, legal reports, or to comply with regulations (such as ITE inspections or rehabilitation grants).
- Legal and insurance evidence: If signed by a qualified professional, it has legal validity and can be used in disputes, damage claims, or expert assessments.
In short, it’s an essential tool for understanding a structure’s real condition and acting accordingly.
When Is This Type of Report Necessary?
A structural pathology report is advisable — and sometimes mandatory — in situations such as:
- Visible cracks that grow in size or shape.
- Deformations or sagging in ceilings, floors, or façades.
- Persistent dampness affecting structural areas.
- Rehabilitation of old or previously damaged buildings.
- Change of use (e.g., converting a commercial space into a dwelling).
- Major renovations that affect load-bearing walls or structural elements.
- Purchase of old properties — to assess their actual condition before investing.
- Neighbor or legal disputes involving structural damage.
- Legal obligations — such as the Technical Building Inspection (ITE) in cities like Barcelona.
What Should a Structural Pathology Report Include?
While each report adapts to the case, it generally includes the following sections:
- Building identification: Address, type, construction year, and current use.
- Inspection details: Dates, methods used, and areas examined.
- Photographic record: Clear images indicating damage and its location.
- Description of detected pathologies: Type, extent, location, and progression.
- Analysis of probable causes: Explanation of the mechanisms behind the damage.
- Risk assessment: Impact on structural safety and urgency of intervention.
- Technical recommendations: Possible solutions, necessary reinforcements, or preventive measures.
- Conclusions: Summary of the diagnosis.
- Signature and seal of a qualified, licensed professional authorized to issue such reports.

Who Can Carry Out a Structural Pathology Report?
This type of report must be prepared by a qualified professional specialized in building structures. The most common professionals with the required competencies are:
- Building surveyors (technical architects).
- Architects.
- Building engineers.
- Civil or structural engineers, depending on the building type.
It is essential that the technician be licensed and experienced in diagnosing structural damage, with updated knowledge in construction regulations, material mechanics, structural reinforcement techniques, and building pathology behavior.
Common Structural Pathologies
Cracks in Load-Bearing Walls
Vertical or diagonal cracks in load-bearing walls may indicate soil movement, foundation problems, or overloading. They’re especially concerning if they extend across several floors or widen over time.
Reinforced Concrete Corrosion
Steel reinforcement oxidation causes concrete expansion, loss of section, and detachment. It’s common in structures over 40 years old without proper maintenance or exposed to saline humidity.
Differential Settlements
Uneven foundation settlement leads to inclinations, diagonal cracks, and deformations. Causes include expansive soils, poor compaction, or water leaks.
Structural Dampness
Constant moisture in load-bearing elements (such as basement walls) deteriorates materials, reduces strength, and encourages biological or chemical attacks.
Deformations in Timber Structures
Loss of stiffness in wooden beams or trusses due to termites, humidity, or rot can compromise entire roofs or ceilings.
The Importance of the Report Before Any Intervention
One of the most common mistakes is acting without a proper technical diagnosis. Often, superficial fixes (like filling cracks or changing finishes) don’t address the root cause — they may even hide it temporarily and worsen it over time.
A structural pathology report allows informed action, designing a solution that addresses the cause, not just the symptom.
