Condition Surveys, Defect Mapping & Investigation

Understanding the Condition of Your Asset

The condition of a structure or protective system is not always apparent from a general visual inspection. Deterioration can develop beneath coatings, within concrete, around joints and at waterproofing interfaces before the full extent of the problem becomes visible.

H³ Construct undertakes specialist condition surveys and defect investigations across concrete structures, car parks, podium decks, waterproofing systems, protective coatings, industrial floors and other existing assets.

Surveys can be used to investigate a known problem, establish the extent of visible deterioration, support planned refurbishment works or provide information for future maintenance and budget planning.

Our practical experience delivering repair and protection works helps us recognise common deterioration mechanisms and understand how defects can affect the subsequent repair process. Where appropriate, surveys can be supplemented by specialist testing, opening-up works and further investigation to build a clearer picture of the existing condition.

Where structural engineering interpretation or assessment is required, H³ Construct can work alongside the client’s appointed structural engineer or coordinate appropriate specialist input.

The objective is to provide clear, practical information about the condition observed, the extent of identified defects and the appropriate next steps for further investigation, maintenance or repair.

  • What We Survey:

  • Concrete cracking, spalling & delamination

  • Reinforcement corrosion & corrosion staining

  • Protective coating condition & failure

  • Deck waterproofing & water ingress

  • Movement & expansion joints

  • Drainage channels, outlets & interfaces

  • Resin & industrial flooring defects

  • Steelwork corrosion & coating breakdown

  • Surface deterioration & localised defects

  • Previous repairs & areas of recurring failure

  • Traffic coatings & demarcation condition

  • Defects affecting planned refurbishment works

Surveys Tailored to the Asset

Defect Mapping
Systematic recording and measurement of visible defects to help establish locations, quantities and the potential scope of remedial works.

Suitable for: concrete repairs • coating failures • waterproofing defects • flooring deterioration

Targeted Defect Investigation
Focused investigation of a particular problem such as water ingress, recurring cracking, joint failure, coating breakdown or localised deterioration.

Suitable for: known defects • recurring failures • repair planning • troubleshooting

Specialist Investigation & Testing
Where visual inspection alone is insufficient, further investigation and specialist testing can be undertaken or coordinated to provide additional information about the substrate or deterioration.

Suitable for: refurbishment planning • concrete investigation • unknown deterioration • consultant-led investigations

Specialist Testing & Investigation

Some defects cannot be fully understood through visual inspection alone. Where additional information is required, H³ Construct can undertake or coordinate further investigation and specialist testing as part of the survey process.

Depending on the structure and purpose of the investigation, this can include hammer tapping and delamination surveys, concrete breakout and opening-up works, reinforcement location, cover measurements, coating thickness assessment, moisture testing and other site-based investigation.

Where required, specialist testing organisations can also be engaged for laboratory or more detailed testing such as chloride analysis, carbonation depth testing, petrographic examination and other concrete investigations.

The scope of testing is developed around the information required from the survey rather than applying the same investigation regime to every structure.

Where results require structural interpretation, remaining-life assessment or engineering design, the findings can be provided to the appointed structural engineer or other suitably qualified consultant for assessment.

Combining practical site investigation with appropriate specialist testing can provide a much clearer basis for developing repair and refurbishment works.

How We Survey

Our Survey Approach

1. Define the Requirement
Establish why the survey is being undertaken, the areas to be inspected and the information required from the investigation.

2. Review Available Information
Where available, review previous reports, drawings, specifications, repair records and information relating to known defects.

3. Inspect & Investigate
Undertake the agreed inspection, defect mapping, measurements and site investigation while recording the condition observed.

4. Specialist Testing Where Required
Undertake or coordinate additional testing where visual inspection alone cannot provide the information required.

5. Report & Next Steps
Present the findings clearly, supported by photographs, defect information and recommendations for further investigation, maintenance or remedial works as appropriate.

  • What You Can Receive

    Depending on the scope of the survey, deliverables can include:

  • Photographic condition report

  • Defect schedules & location plans

  • Mapped repair areas

  • Measured or estimated repair quantities

  • Testing and investigation results

  • Identification of areas requiring further investigation

  • Recommended next steps

  • Outline remedial options

  • Budget costs where requested

  • Information to support refurbishment planning and tendering

Surveys in Live Operational Environments

Condition surveys are frequently required within assets that remain fully operational. Car parks, shopping centres, industrial facilities and commercial buildings may continue to accommodate vehicles, pedestrians, employees and members of the public throughout the investigation.

H³ Construct plans survey activities around these operational requirements, with access, work areas and inspection methods considered before site activities begin.

Where surveys require access equipment, localised opening-up, hammer tapping or other intrusive investigation, appropriate controls and segregation can be introduced around the inspection area.

We coordinate with clients, managing agents and site teams to minimise disruption while ensuring that the areas included within the agreed survey scope can be inspected effectively.

This practical experience of working within live environments allows investigation to be undertaken with the subsequent repair and delivery requirements already in mind.
