How extraction works

Bricks are carefully removed in a line near the base and at intervals higher up where needed. The fill is broken up and drawn out with an extraction vacuum, the cavity is cleared and checked with a camera, and the bricks are rebuilt in matching mortar. Extracted material is bagged and disposed of properly.

What is included in Coleraine

  • Full extraction and cavity clean
  • Camera check before rebuild
