Why dry ice blasting

The most suitable technology for sensitive listed surfaces

Zero abrasion on stone

Dry ice sublimates with no mechanical action on the substrate. It does not scratch, does not dig and does not tear away material, unlike sandblasting or pressure washing which irreversibly degrade stone.

No water, zero infiltration

Pressurised water infiltrates joints and accelerates the degradation of old masonry. Dry ice blasting brings no moisture at all, ideal for the thick walls of historic buildings.

Preserves architectural details

Mouldings, sculptures, cornices, ornaments: dry ice cleans with precision without erasing details. The nozzle is adjusted to each area for a surgical result.

Intervention report

Icetec provides a detailed report of each intervention, useful for restoration files, grant applications and reports to heritage authorities.
