After an earthquake, installed barrier, anchored mesh and drapery lines may look standing while the anchors, braking elements and rope connections have taken load. What is done in the first 72 hours, what is checked, when to call us; an inspection request with one link.
Why a separate inspection
An earthquake triggers rockfall and slope instability in two ways: blocks that break off during the shaking, and blocks loosened by the shaking that will break off days later. An installed protection line may have met the first wave; whether it is ready for the second is not known without looking. Flexible systems absorb energy by deforming: an opened braking element, a stretched rope or a shifted plate looks "intact" from outside.
A post-earthquake inspection differs from a periodic one: it is fast, it first ranks the hazard, then it measures. If your installed line has a tag, the inspection and findings are entered on the line's tag; if not, the first inspection starts with a tag record.
The first 72 hours: what the owner does
| Hours | What is done |
|---|---|
| 0 – 24 | Traffic and access decision for the road and structures below the line: if there is a visible block, a full net or a bent post, the line counts as "loaded" and the area below is closed. Record with photographs; if there is a tag, report through its QR code. |
| 24 – 48 | Observation from a distance: new breakout marks in the source area, new cracks or dust traces on the slope, new accumulation behind the net. Binoculars and a drone are enough; nobody goes under the line. |
| 48 – 72 | Inspection request and crew plan: which lines first (above settlements and main roads), access, weather. While the risk of aftershocks continues, nobody works in front of the line; the inspection is done from above and from the sides. |
Component checklist
| Component | Red flag (report at once) | Yellow flag (take into periodic inspection) |
|---|---|---|
| Anchor heads and base plates | Plate separated from the ground, loose nut, new crack or scour around the anchor | Superficial mortar crack |
| Posts | Bent, rotated at the base hinge, impact marks | Small horizontal deviation |
| Support and tensioning ropes | Bundle of broken wires, slipped clip, slack rope | Local crushing |
| Braking elements | Opened, elongated, deformed ring | Cracked paint, faint mark |
| Net and panel connections | Tear, opened ring, broken shackle, blocks accumulated behind the net | Small notch |
| Anchored mesh and drapery | Lifted plate, new loosening under the mesh, slack top edge rope, new accumulation at the toe | Local slackness in the mesh |
| Slope and source area | Newly opened crack, hanging block, new breakout surface | Fine ravelling on the surface |
A single red flag makes the line "loaded": the area below stays closed, measurement and repair are planned. What is measured and how decisions are made is in the tables on the inspection, maintenance and service life page.
What we provide
The inspection crew records the component checklist in a report with photographs, assesses the remaining capacity of the line, replaces opened braking elements and damaged panels, empties the net, and proposes scaling or additional protection for blocks that have loosened in the source area. The report goes to the owner and its summary is written on the tag. We also work on other manufacturers' systems.
To request an inspection: post-earthquake inspection request — the location and length of the line and, if any, the tag code are enough. Emergency phone: +90 312 215 43 47.
