Areas of Application
BLOCK C902 TERRA XPRESS is used for quick, permanent sealing of leaks and water ingress in concrete, masonry and natural stone structures. Upon contact with BLOCK C902 TERRA XPRESS, the water flow stops within seconds. In the special sealing system AQUASTOPP, BLOCK C902 TERRA XPRESS is required in the second work step after BLOCK C901 TERRA SPECIAL. Areas of application include sealing leaks in basement buildings, underground car parks, tunnels, dams, sewage systems, sewage treatment plants, concrete pipes, elevator shafts, rainwater cisterns, harbour walls, pipe penetrations (as a flanking measure), bunker systems, dams, sprinkler tanks, tunnels, locks, underpasses, lifting systems, Assembly pits, pumping stations and in all places where sealing from the outside is not possible.
The surface must be solid, stable, clean and free of plaster. Loose parts and residues of oil, formwork oil, grease, dust or other separating layers of any kind must be removed.
To seal a leak, a handful of BLOCK C902 TERRA XPRESS is dry pressed together into a solid lump, similar to a snowball. After forming, this lump is pressed very quickly and with appropriate pressure into the water ingress point until the water is stopped. If there is very strong water pressure or a larger water jet, quickly mix BLOCK C902 TERRA When processing as a component in the special waterproofing system AQUASTOPP, the first layer of BLOCK C901 TERRA SPECIAL is rubbed dry with BLOCK C902 TERRA XPRESS. When processing, non-profile gloves must be worn as occupational safety.
