First pumpable and flow-grade concrete replacement mortar: valuable problem solver for time-critical construction sites

With weber.floor 4640 Outdoor RepFlow Saint-Gobain Weber offers the first flow-grade concrete replacement mortar, which can be processed with modern pump technology. This allows large areas to be placed in just a few hours - an invaluable advantage for time-critical or delayed construction projects.

The pumpable and flow-grade weber.floor 4640 Outdoor RepFlow is pumped by hose from the Weber Mixmobil or a silo directly to the job site, where it is poured while standing and levelled with a wobbling bar. Compared with conventional flooring works, this technology can save up to 90% of the time and staff.
