Materials & Processes
Special paraffin (ISOTEC injection agent)
Injected into the dried-out masonry during horizontal barrier installation, permanently stopping capillary water transport.
Masonry and concrete
Building materials of the buildings to be remediated, including crack injection for crack widths above 0.2 mm.
Bitumen thick coating (ISOTEC-VAS)
Two-layer waterproofing with fabric reinforcement and a total thickness of at least 4 mm for exterior waterproofing.
Polymeric thick coating (ISOTEC combination flexible waterproofing)
Flexible waterproofing structure for earth-contact components, combined with thermal insulation boards and sealing plaster.
Restoration plaster
Absorbs building-damaging salts and allows moisture from the masonry to diffuse out.
Liquid plastic
Liquid-applied waterproofing system for seamless surfaces.
Climate board and thermal insulation boards
Raise the wall surface temperature, regulate the indoor climate and prevent condensation and mould formation.
