Render Façade Remediation

Trident Facades provides render façade remediation services for buildings affected by cracking, deterioration, water ingress, detachment or other defects within the external render system.

The appropriate solution may range from localised repair through to complete removal and replacement of the render build-up.

Common Render Façade Problems

Render systems can develop defects including:

  • Cracking
  • Delamination
  • Detachment
  • Impact damage
  • Water ingress
  • Failed joints
  • Failed interfaces
  • Deterioration
  • Poor adhesion
  • Substrate movement
  • Defective insulation
  • Defective detailing

The cause of the defect should be established before remedial works are specified.

Render Remediation Options

Depending on the condition of the façade, remediation may include:

  • Localised repairs
  • Crack repair
  • Re-rendering
  • Removal of defective areas
  • Complete render removal
  • Substrate repairs
  • Insulation replacement
  • Membrane replacement
  • Waterproofing
  • Interface repairs
  • Complete external wall refurbishment

Investigating Render Defects

Visible cracking or staining does not always reveal the underlying cause.

Where required, intrusive investigation can establish:

  • Wall construction
  • Insulation type
  • Substrate condition
  • Fixings
  • Membranes
  • Cavity construction
  • Moisture pathways
  • Interface details

Our survey team can undertake façade investigations and opening-up where additional evidence is required.

Render Removal and Replacement

Where the existing render system cannot be satisfactorily repaired, removal may be required before the underlying wall is prepared for a new system.

Replacement design can consider:

  • Render system
  • Insulation
  • Substrate
  • Fixings
  • Membranes
  • Fire performance
  • Thermal performance
  • Weather resistance
  • Interfaces

Render and External Wall Remediation

Render may form only one component of a wider external wall system.

For that reason, remediation should consider the complete wall construction rather than treating the render finish in isolation.

Complete Render Remediation

Trident Facades can support the project from:

Investigation → Diagnosis → Remediation Strategy → Design → Removal/Repair → Replacement → Completion
