Tripe Walls - A Sealing Challenge

» Triple walls elements are standard today from a technical point of view and have many advantages that cannot be overlooked on the construction site. Since two construction joints are produced transversely from the inner and outer shells and a core that has been cast in situ when making the wall, any water that occurs should be stopped at the outer shell. This prevents any slip or creepage of the pipe penetration.

» Depending on the requirements and the loads involved in that particular case, we can offer in the form of our KRASO DFW Pipe Penetrations a simple and tight solution to meet this challenge!
