Projex Group  have decided to address a definite need in the Australian/New Zealand market for a range of specialty remedial products, which can be used by a competent tradesman.

Koster, from Germany, have specialised in such systems for decades in different parts of the world.

Whether the project is restoration of a heritage building, reinstalling failed horizontal barriers in masonry, plugging in-rushes of water within seconds, potable water solutions, waterproofing products, which work from both the positive and negative side of the structure, Projex Group/Koster now have the optimum solution.

Koster products can be used for rectification of most masonry substrates because the technology is not based on water soluble silicates that only work and react with new concrete.

The products that are now available from Projex Group include:

  • KD2 Blitz powder is a highly reactive powder with short setting time that can be used to stop rushing water within seconds.
  • KB Flex 200 sealing paste is a permanently plastic sealing compound for sealing of tubular feedthroughs against moisture and pressurised water. It can be applied to wet, moist and dry substrates and adheres to all building substrates.
  • NB1 Grey is a cementitious waterproof system for sealing against ground water non-pressurised and pressurised. NB1 Grey has been certified for use in potable water applications.
  • KSK BL Primer is a solvent free Low VOC Bitumen Primer with good adhesion to dry and moist substrates.

Projex Group also stock Kosters Urethane cleaner and Bitumen cleaner.
