Haulbowline Naval Base

Hearthstone works included lime mortar pointing, leadwork, limestone repairs and limestone replacement.

Stonework cleaning (removing dirt, grime, moss, algae) using our DOFF System which uses superheated water designed and developed to effectively remove dirt and grime without causing harm or shock to the substrate.

DOFF System can be used internally or externally for use on surfaces such as brick, stone, concrete, tiled (glazed and encaustic), wood, faience and terracotta.

The superheated water vapour will remove paint, moss, algae, fungi and other biological matter and will also kill off spores. With no need to use a chemical biocide during the removal process or as a protection against further biological activity.
