Subsequently produced load-free zone under a roadway

To protect subterranean concrete structures against unintended loads, a flatly load-free layer must be created. This prevents unintended load, by deflections due to dynamic traffic loads (heavy vehicles, trucks, etc.). With the Egcovoid® former, you can reach a planned load-handling after the concreting.

Subsequently produced load-free zone under a roadway

How to:

  • The Egcovoid® panels are laid over a sandbed or similar underground. The choice of the plate thickness (35 mm or 50 mm) depends on the calculated deflection of the decoupled roadway plate.
  • The individual plates are connected securely to each other with a hose system (MAX FRANK accessories) at the prefabricated valve points. The sufficiently long tube end is guided upwards over the bottom plate.
  • A PE film is laid over the Egcovoid® panels as additional moisture protection, a clean concrete layer is applied as mechanical protection to the PE film.
  • After the base plate hardens, the Egcovoid® former are watered via the mounted hose system. Due to the water applied, the Egcovoid® panels create a load-free layer and an independent bearing bottom plate.
