A KÖSTER tem vindo a produzir membranas para coberturas desde os anos 80. Muitas membranas desta altura estão ainda hoje visíveis e intactas em muitas coberturas incluíndo a cobertura da própria fábrica da KÖSTER.
The KÖSTER ONE-DAY-SITE Packer allows injection work to be completed in one day.
The screw packer for pressure injection has a firmly mounted cone-head fitting and two non-return valves. Immediately after injecting, that part of the port which protrudes from the wall can be unscrewed and removed. The central part of the port stays in the wall sealing the borehole so that no injection material can flow out of the borehole even under high pressure. The borehole can then be closed immediately after injection.
