Joints & Repair Method

In many cases in-situ concrete barriers need to be repaired, extended or connected to existing objects. The EP series offers patented joint solutions to safely eliminate all those weak points. DELTABLOC® was the first provider of an EN 1317 tested joint and repair method with containment level H2.

  • EP-CJO construction joint to objects
  • EP-REP repair method


End-of-Shift Joint

In-situ concrete safety barriers require "end-of-shift" construction joints every 200 to 400m. DELTABLOC® overcomes this weak point with the introduction of the reinforced joint solution EP-EOS. It ensures reliable breakthrough protection at containment level H2 – tested according to EN 1317.

The EP series is the first in-situ concrete barrier with crash tested “end-of-shift joints”.


Construction Joint to Objects

In many cases in-situ concrete barriers need to be connected to existing objects such as tunnel portals or foundations for gantries and signs.

The EP-CJO safely connects the EP series to rigid objects.


Repair Method

After any repair work the restored safety barrier must again ensure the full safety performance as originally tested. DELTABLOC® was the first provider of a crash tested repair method.

The EP-REP ensures that the barrier provides full safety performance even after significant repair works.
