Project Overview

In December 2022, 4,950m² of Concrete Canvas^® CCX-UTILITY^® GCCM (CCX-U^®) was used to protect a slope in Črni Kal, Slovenia. Situated alongside a single track railway, the slope required weed suppression to reduce fire risk

Slope prior to works being carried out, mini excavator used to dig anchor trenches, CCX-U^® laid vertically down the slope, intermediate fixing to slope substrate

to install, while the line remained open

Solution

Alternative solutions such as shotcrete was considered, however, this would have required the line to close for an extended period of time beyond the regular maintenance periods to allow heavy plant machinery onto site and would have been both time consuming and costly for the client.

CCX-U^® was chosen as it didn’t require line closure (just regular railway maintenance), eliminating associated disruption for users of the railway.

CCX-U^® overlapped and jointed using stainless steel screws

Anchor trenches backfilled with excavated substrate

Design & Installation

Vegetation, large rocks and debris were removed
CCX-U^® Bulk Rolls specified and deployed from teh railway line for easy deployment
Vertical layup
CCX-U^® secured to the slope with intermediate fixings as per large structure detailing
Overlaps jointed using stainless steel screws
Hydrated twice using a water tank and hose

Completed Installation

Summary

4,950m² of CCX-U^® was installed in just 13 days by a team of 6 in cold weather conditions. The material was installed only in the regular railway maintenance periods every Monday. The use of CCX-U^® allowed the line to stay open, and provided a more ecological solution than the shotcrete alternative, while the speed and ease of installation, together with possibility not to work continuously reduced end costs for the client.
