Dry ice blasting for heritage & monuments
Natural stone, listed brick, sculptures, ornaments and historic facades require a non-abrasive cleaning technique, without chemicals and without water. Dry ice blasting is the ideal solution for heritage sites in Wallonia and Belgium.


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.
