Method for sealing house openings, especially doors and windows of basement area

摘要

The opening cross-section is inflated by a matching valve mating hose (4) which is provided in a moisture-proof closure body (5) which has a constant seal retainer for evenly limiting the hose expansion, using the required pressure. The valve (7) of the mating hose which is formed like a rubber hose, is plugged in a channel-outflow and inflated, so that a safer seal-lock is formed. The pump pressure is greater than the potential water pressure in the drain system, and is preferably 2 to 3 bar.
