The external wall is an important part of a building’s overall construction.
Depending on the building and its construction, façade-related issues can involve:
Where defects are identified, the appropriate response needs to be established from the available evidence and the requirements of the project.
Concerns relating to an external wall can arise from a range of circumstances, including:
Not every external wall defect requires complete replacement.
The appropriate remediation solution depends on the construction, condition, assessment findings and design requirements.
Where a building has undergone an external wall assessment, the findings can help establish what remediation may be required.
Our dedicated survey team, Trident Facades Surveys, undertakes façade investigations, opening-up and external wall survey work.

Where appropriate, assessment evidence can then feed into the remediation process.
A façade remediation project can progress through:
Investigation → Assessment → Remediation Strategy → Design → Procurement → Remedial Works → Completion
The assessment establishes the issues.
The remediation strategy determines the appropriate response.
The design develops the technical solution.
The remediation contractor then delivers the works.
Depending on the project, remediation may include:
PAS 9980 provides a methodology for undertaking fire risk appraisals of external walls.
Where a FRAEW or other external wall assessment identifies remediation requirements, the findings can become an important part of the subsequent remediation process.
For assessment and survey requirements, see Trident Facades Surveys.
A remediation strategy should establish how identified defects are going to be addressed.
This may involve determining:
See our Façade Remediation Strategy service.
Trident Facades is able to progress beyond consultancy and design into physical façade remediation works.
This provides a route from identified façade defects through to practical remediation.
