Stone Facade

A Facade Facing Replacement. Preserved with ZYTERRA.

Restoring and protecting a 12 year old natural stone facade while retaining its original character and colour.

Before
After

The Problem

  • Water penetration caused salt efflorescence and crystallisation across the natural stone.
  • The stone was weakening, deteriorating and crumbling at the surface.
  • Wholesale replacement would have been disruptive, and new stone would not match the naturally weathered facade.

The ZYTERRA Treatment

  • Weakened surface layers were removed, joints repaired and stones too weak to retain were selectively replaced.
  • ZYTERRA was then applied as the final strengthening and protective treatment.
  • One treatment provided strengthening and water protection while maintaining vapour permeability.

The Result

  • The vast majority of the original 12 year old stone was retained.
  • The conventional month long wait and a separate sealer visit were avoided.
  • The rope access crew, equipment and machinery were required only once rather than twice.
  • The completed facade retained the character and colour of the original stone.
