POLYCRETE jacking pipes
Superior performance under ground
Underground pipe jacking is a construction method that has been tried and tested for years, and that has well-known, undisputed advantages, especially in residential areas. At the same time this process makes particularly high demands on the pipe due to the extreme jacking loads applied during installation. The pipe must sustain these enormous forces and transfer them evenly and in a controlled manner, which requires perfect dimensional accuracy. Meyer-POLYCRETE has specialized in this application area. Our POLYCRETE® jacking pipes have proven their usefulness in this environment over decades.
The consistent use of high quality resins and aggregate materials in advanced recipes enables the pipes to reliably cope with high jacking forces. Thanks to a modern casting process with subsequent milling of the spigot ends the pipes feature excellent dimensional accuracy. And furthermore the very smooth, non-absorbing outer pipe surface minimizes static and dynamic friction and thus the breakaway and jacking resistance. This allows remarkable jacking lengths without using intermediate jacking stations.
